WooCommerce third-party gateway isn't working on order-pay page
|
<p>I have a third-party payment gateway which works fine on the Checkout page. When the user clicks the Pay button, it actually returns a Javascript command as the redirect, which then opens up a modal iframe to my payment gateway, like so:</p>
<pre><code>public function process_payment( $order_id ): array {
include_once dirname( __FILE__ ) . '/includes/flywire-payment-gateway-request.php';
$FW_request = new WC_Gateway_Flywire_Request( $this, $order_id );
try {
$config= $FW_request->get_config();
} catch ( Exception $e ) {
wc_add_notice( $e->getMessage(), 'error' );
return array(
'result' => 'failure',
'redirect' => ''
);
}
// TODO: add optional call to Google Tag action
$return_array = array(
'result' => 'success',
'redirect' => 'javascript:window.flywire.WooCommerce.show(' . json_encode($config) . ')'
);
$logger = wc_get_logger();
$context = array( 'source' => 'flywire' );
$log = "Initializing Checkout with JSON:\n" . json_encode($return_array) . "\n";
$logger->info( $log, $context );
return $return_array;
}
</code></pre>
<blockquote>
<p>2022-02-17T11:16:19+00:00 INFO Initializing Checkout with JSON:
{"result":"success","redirect":"javascript:window.flywire.WooCommerce.show("{\"provider\":\"woocommerce\",\"env\":\"demo\",\"locale\":\"en\",\"recipient\":\"\",\"amount\":1800,\"return_url\":\"http:\\\/\\\/localhost:8888\\\/checkout\\\/order-received\\\/58\\\/?key=wc_order_2jw2UT4xADHU3\",\"callback_id\":58,\"callback_url\":\"http:\\\/\\\/localhost:8888\\\/wc-api\\\/WC_Gateway_Flywire\\\/\",\"sender_country\":\"US\",\"sender_first_name\":\"Test\",\"sender_last_name\":\"Testing\",\"sender_address1\":\"1 Test\",\"sender_phone\":\"000000000\",\"sender_city\":\"Town\",\"sender_zip\":\"94043\",\"sender_email\":\"admin@example.com\",\"student_first_name\":\"Test\",\"student_last_name\":\"Testing\",\"student_email\":\"admin@example.com\"}")"}</p>
</blockquote>
<p>On the order-pay endpoint, clicking the Pay button generates the exact same button, but the JS does not fire or trigger the breakpoint I put in it. If I manually try to call the JS from the Dev Tools Console, like below, it triggers the breakpoint:</p>
<pre><code>window.flywire.WooCommerce.show('foo')
</code></pre>
<p>So, I know that the JS script has been enqueued properly and is included in the page. I also know that the <code>process_payment</code> function is returning the correct redirect value. And yet, nothing happens.</p>
<p>As far as I can tell, function <code>process_order_payment</code> in class-wc-checkout.php is what actually takes the return value from my gateway's <code>process_payment</code> function and does its magic. I added logging there too and can see it fire when I click Pay from the Checkout page. But, nothing happens from the Order Pay page.</p>
<p><strong>UPDATE:</strong> No solution yet but found some more information. <code>process_payment</code> is called in two places. For checkout, it is called by <code>class-wc-checkout.php</code>. For the order payment page, it is called by <code>class-wc-form-handler.php</code>. The code is in both places is <em>almost</em> the same.</p>
<p>Code on <code>class-wc-checkout.php</code>:</p>
<pre><code>// Process Payment.
$result = $available_gateways[ $payment_method ]->process_payment( $order_id );
// Redirect to success/confirmation/payment page.
if ( isset( $result['result'] ) && 'success' === $result['result'] ) {
$result['order_id'] = $order_id;
$result = apply_filters( 'woocommerce_payment_successful_result', $result, $order_id );
if ( ! wp_doing_ajax() ) {
// phpcs:ignore WordPress.Security.SafeRedirect.wp_redirect_wp_redirect
wp_redirect( $result['redirect'] );
exit;
}
wp_send_json( $result );
}
</code></pre>
<p>Code on <code>class-wc-form-handler.php</code>:</p>
<pre><code>$result = $payment_method->process_payment( $order_id );
// Redirect to success/confirmation/payment page.
if ( isset( $result['result'] ) && 'success' === $result['result'] ) {
$result['order_id'] = $order_id;
$result = apply_filters( 'woocommerce_payment_successful_result', $result, $order_id );
wp_redirect( $result['redirect'] ); //phpcs:ignore WordPress.Security.SafeRedirect.wp_redirect_wp_redirect
exit;
}
</code></pre>
<p>In the checkout version (which works), it does not call <code>wp_redirect()</code> if WP is doing AJAX and instead sends the JSON to the AJAX. In the order payment page version, it always just redirects with <code>wp_redirect()</code>. It's the <code>wp_send_json()</code> that allows the "Javascript:" protocol to work, but I don't understand why paying from the checkout page works differently from the order payment page.</p>

Reproduce OxMetrics' ARFIMA model in R
|
<p>I am working to reproduce some results from OxMetrics (<a href="http://www.timberlake.co.uk/software/oxmetrics.html#ox-pro" rel="nofollow">Ox Professional version 7.10</a>) in R, but I am having a hard time figuring out exactly I get the right specification in R. I do not expect to get identical estimates, but somewhat similar estimates should be possible (see below for estimates from OxMetrics and from R).</p>
<p>Can anyone here help me figuring out how I do what OxMetrics does in R?</p>
<p>I've tried using <code>forecast::arfima</code>, <code>forecast::Arima</code>, <code>fracdiff::fracdiff</code>, and <code>arfima::arfima</code> So far I came closest with the latter.</p>
<p>Below is data and code,</p>
<p>The blow results is from is from OxMetrics ARFIMA(2,0,2) model estimated using Maximum likelihood and from R using <code>arfima</code> from the <code>arfima</code> package (code blow the longer data string).</p>

JS/jQuery: When prepending a dynamic element, how to force the container div to extend upwards instead of downwards?
|
<p>If you've noticed, it seems that when <code>prepend()</code> is used, the additional elements get piled at the top but the container div is extended downwards. </p>
<p>Comparing with FB's load previous message, you will notice that elements are loaded on top of each other but your <strong>view does not change</strong>. It is like <code>append()</code> except the container div "seems" to extend upwards. </p>
<p><strong>I've tried doing this to <em>simulate the div extending upwards</em> but failed</strong></p>
<pre><code>var scrolldif = $('#response')[0].scrollHeight-$('#response').scrollTop();
$('#response').scrollTop(scrolldif);
</code></pre>

Bundle install failure for an existing ruby app. I suspect libv8
|
<p>I have the rather unfortunate position of inheriting a rails app from a previous developer. I have the joy of both trying to learn ruby and picking apart the old code to fix what's broken. I don't have any means for contacting the former developer, nor do I have much knowledge of the app other than that it uses ruby on rails. I'm much more familiar with the .net environment, so getting RoR up and running is proving to be a bit of a challenge. </p>
<p>I'm simply trying to clone their code repo locally and try to run their code on a local rails server. I was able to clone, the next thing I tried was to run bundle install and I got this massive block of text that I can't make heads or tails of.</p>

<p>To me, it looks like there's an issue with libv8, but there is also a warning about python 2 not being installed, which it is, along with being added to the path variable. I should add my dev environment is 64-bit Windows 8.1. Has anyone got this working? </p>

DELETE ROW command is getting skipped without any ERROR
|
<p>I have two tables, table1 has multiple rows with data, while table2 is empty.</p>
<p>I m trying to perform a simple INSET into and DELETE command in php to add the selected row from table1 to table2 and at the same time DELETE the selected row from table1</p>
<p>But here, it gets inserted to table 2 and doesn't get deleted from table 1 but returns to main page without any error.</p>
<p>My code as follows:</p>
<p>Calling row content from table1 to user page:</p>
<pre><code><?php
$sql2 = "SELECT * FROM apromocode ";
$result2 = $conn->query($sql2);
if ($result2->num_rows > 0) {
while($row2 = $result2->fetch_assoc()) {
?>
<tr >
<form id="promocodesub" action="apromocodesubdelete.php" method="post">
<td>
<?php echo ($row2["id"]); ?>
</td>
<td>
<?php echo ($row2["code"]); ?>
</td>
<input type="hidden" form="promocodesub" name="code" value="<?php echo ($row2["code"]); ?>"/>
<td>
<?php echo ($row2["occation"]); ?>
</td>
<input type="hidden" form="promocodesub" name="occation" value="<?php echo ($row2["occation"]); ?>"/>
<td>
<?php echo ($row2["about"]); ?>
</td>
<input type="hidden" form="promocodesub" name="about" value="<?php echo ($row2["about"]); ?>"/>
<td>
<?php echo ($row2["discount"]); ?>
</td>
<input type="hidden" form="promocodesub" name="discount" value="<?php echo ($row2["discount"]); ?>"/>
<td>
<?php echo ($row2["date"]); ?>
</td>
<td>
<button form="promocodesub" type="submit" name="deleteId" value="<?php echo ($row2["id"])?>"class="promocodedelete">Delete</button>
</td>
</form>
</tr>
<?php
}
} else {
echo "0 results";
}
?>
</code></pre>
<p>So, when user open the page, he will see all row contents lined up in sequence along with "delete" button for each. When the user presses the delete button for that particular row, it will get inserted to table2 and should get deleted from the table1 with the following script:</p>
<pre><code><?php include('amerchantassign.php'); ?>
<?php
$servername = "localhost";
$dbusername = "root";
$dbpassword = "";
$dbname = "";
$code = $_POST['code'];
$occation = $_POST['occation'];
$about = $_POST['about'];
$discount = $_POST['discount'];
$date = date_default_timezone_set('Asia/Kolkata');
$date = date('M-d,Y H:i:s');
enter code here
$conn = new mysqli ($servername, $dbusername, $dbpassword, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$deleteId= $_POST['deleteId'];
$sql="INSERT INTO apromocodehistory (code, occation, about, discount, date)
SELECT code, occation, about, discount, date
FROM apromocode
WHERE id= $deleteId";
if ($conn->query($sql) === TRUE) {
$sql4 = "DELETE FROM feedback WHERE id = '$deleteId' ";
if ($conn->query($sql4) === TRUE) {
echo '<a href="amerchantassign.php"></a>';
} else {
echo "ERROR" . $sql4;
}
} else {
echo "ERROR" . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
</code></pre>
<p>Any Suggestions are appreciated...</p>

Linked List, Stuck on file management
|
<p>I am trying to read from a file called data.txt. and store it into a LL which looks like this</p>
<pre><code>Quanta 2
New 2
Ready 2
A 1 3
B 3 4
C 5 6
D 7 9
</code></pre>
<p>I would like to read that file, one line at a time, storing each line at a node in a LL, e.g A 1 3, will be at one node.</p>
<p>The desired layout is this </p>
<pre><code>Name Value
Quanta 2

-------------------------
Process NUT AT

VBA No resultset from stored procedure that backups database
|
<p>I need to execute a stored procedure that make some changes to a specific database and back it up at the same time. For some reason, when the backup code is active, in VBA's recordset I don't get any row but the backup is effectively created. </p>
<p>The recordset comes closed and Err.Description is "Operation is not allowed when the object is closed." If I comment the backup code in the stored procedure, the recordset comes opened I get the 1 row with the results.</p>
<p>In the vb code I am calling the stored procedure with adAsyncExecute and waiting using the following code:</p>
<p>Any Idea why the recordset comes closed and does not return 1 row when executing successfully the sp? </p>
<p><strong>Edit:</strong>
If I execute the sp in SSMS with exec, it works and I can see the row with the values.

plotting input data in simmr and being able to change colors of food sources and consumer group data
|
<p>regarding stable isotope analysis based on package simmr. I am interested in plotting the input data but chosing my own colors for food sources and consummer data. The example for multiple groups in the help section automatically choses the colors.</p>
<p>I would like to know if anyone can help me understand how to modify the command plot(simmr_4,group=1:8,title='Isospace plot of Inger et al Geese data') in the example so that I can choose my own colors for both food sources and consumer group data.</p>
<p>right now I dont have any data, but expecting data collection in the future. I am currently working on the data and example from the simmr author, the one thing I need is to be able to change the points colors</p>
<p>here's the authors data and example which can be found be simple using help on r for plot.simmr</p>

Trie Tree. Unable to access memory

When running tests, I can successfully add several hundred, or even thousands of nodes without issue, until it eventually crashes. Error: Unable to access memory.

Shift contents of array using parameters in C++
|
<p>I have been playing around with a bit of code for the past few weeks. The code is a display of the number 1. I want to essentially create a dot matrix style print out, where the 1 is continuously shifted to the right.
Here is where I am so far:</p>
<pre><code>#include <iostream>
using namespace std;
/* use function to shift all characters one place to the right */
/* use a function to declare the characters of the fiqure */
int i, j;
int matrix([int i][int j]);//dont think this is right
</code></pre>
<p>I have declared my variables, and the matrix with the parameters I and j </p>
<pre><code>int main()
{
//should the matrix be a global function, therefore can be accessed by the move function?
/* the matrix is contained within the matrix function. The goal of main, is to manipulate
the matrix to transponse the elements to the next column*/
// 8 rows and 13 columns
for (i = 0; i < 8; i++)
{
int p = (j + 3)%13;
for (j = p; j < 13 ; j++)
{
matrix[i][j] = matrix[i][j + 3];
//priting out the matrix
cout << matrix[i][j];
}
cout << "\n";
}
cout << endl;
}
int matrix(int i, int j)
/* this function sets up the matrix and returns the value of the matrix.
this function should simply be a display function */
{
int matrix[8][13] = { { 0,1,1,1,1,1,0,0,0,0,0,0,0 },
{ 1,1,1,1,1,1,0,0,0,0,0,0,0 },
{ 0,0,1,1,1,1,0,0,0,0,0,0,0 },
{ 0,0,1,1,1,1,0,0,0,0,0,0,0 },
{ 0,0,1,1,1,1,0,0,0,0,0,0,0 },
{ 0,0,1,1,1,1,0,0,0,0,0,0,0 },
{ 0,0,1,1,1,1,0,0,0,0,0,0,0 },
{ 0,0,1,1,1,1,0,0,0,0,0,0,0 } };
//display the elements
for (i = 0; i < 8; i++)
{
for (j = 0; j < 13; j++)
{
//priting out the matrix
cout << matrix[i][j];
}
cout << "\n";
}
cout << endl;
return matrix[i][j];
}
</code></pre>
<p>Here is the main function, where I attempt to assign actual parameters for the matrix and pass them to the matrix display. The main function specifically defines a variable ‘p’ which (the plan is anyway) to use this variable to cause a shift to the right.
I am using the modulo 13 operator to attempt to clear (or return to 0) values after the shift, so the 1 appears to move across the matrix</p>
<p>In addition to the functions above, I have included the last bits from my code which are essentially notes and ideas that I am attempting now. </p>
<pre><code>/*
int array_size = sizeof(matrix) / sizeof(matrix[0]);
for (i = 0; i < 8; i++)
{
for (j = array_size-1; j > 0; j--)
{
matrix[j] = matrix[j - 1];
}
matrix[0]=
cout << "\n";

C++ on Solaris: How to cope with "Formal argument" wrongly passed error?
|
<p>I am trying to compile the SMT solver Z3 (Version 4.5.0) from Microsoft Research on a Solaris 10 (Sparc) with Solaris Studio 12.3 (and this is due to constraints that I cannot change, so please do not hint to gcc/g++).</p>
<p>I already had to make some (more or less trivial) code changes in order to come to the error I am opposed with now:</p>

<p>The code causing the error can be found <a href="https://github.com/Z3Prover/z3/blob/z3-4.5.0/src/util/map.h" rel="nofollow noreferrer">here</a> at line 54.</p>
<p>I already poked around with a cast to <code>std::pair<expr*, int></code>, but as this is code used with different types, this lead to a similar error with <code>unsigned</code>.</p>
<p>Can anybody help me with this error?</p>

what's wrong with this simple code(objective c)?

<p>i want to download some webpages ,but this example code seems doesn't work.
it prints "begin download" and then exits,why the delegates method does not be executed?

Changing launcher activity when the app is launched second time onwards android
|
<p>I am developing an android app where I have a launcher activity that takes the user's email id. When the user enters his email id he is redirected to another activity that asks for another user authentication in a <code>WebView</code>. After the user is successfully authenticated from this activity, the further execution starts. </p>
<p>Now, I want that after the user is authenticated on the second activity and he closes the app. Next time when he starts the app he should not see the launcher activity and get redirected to the second activity.</p>
<p>Is there any way to do this?
Thanks</p>
<p>My code:-</p>
<pre><code>Animation animTranslate = AnimationUtils.loadAnimation(Login.this, R.anim.translate);
animTranslate.setAnimationListener(new AnimationListener()
{
@Override
public void onAnimationStart(Animation arg0) { }
@Override
public void onAnimationRepeat(Animation arg0) { }
@Override
public void onAnimationEnd(Animation arg0)
{

Why is my modified Pol01 running in batch mode works for all polarized photon states except for left circularly polarized photons?
|
<p>I am attempting to use Pol01 example to examine the angular distribution of initially polarized photons Compton scattering off G4_Si.<br />
I have had to include several lines of code in the SteppingAction.cc which will print out information like, for example, the Compton scattering angle and the photon's final kinetic energy.</p>
<p>The simulations seems to work well for horizontally and vertically polarized photons, linear polarized +- 45 degrees and right circularly polarized (RCP) photons. But when I try and run the simulation for left circuarly polarized (LCP) photons I get a segmentation fault part way through the printing of the information to my terminal window.</p>
<p>In macro code this is what I found</p>
<pre><code>### RCP (works)
# /gun/polarization 0. 0. 1.
### LCP ( Segmentation fault )
/gun/polarization 0. 0. -1.
### vertical ( works )
# /gun/polarization -1. 0. 0.
### horizontal ( works )
# /gun/polarization 1. 0. 0.
### LP ( 45 degrees ) (works)
# /gun/polarization 0. 1. 0.
### LP ( -45 degrees ) ( works )
# /gun/polarization 0. -1. 0.
/gun/particle gamma
#
/gun/energy 511 keV
</code></pre>
<p>However, above this code there is the following instruction</p>
<p><code>/polarization/volume/set theBox 0. 0. 0.08</code></p>
<p>If I set <code>0.08</code> to <code>0.</code> , then I do not get the segmentation fault. I would like help in figuring out why only LCP photons cause the segmentation fault?</p>
<p>FYI, the only extra code I included into Pol01 (in SteppingAction.cc) is the following</p>
<pre><code> // Inside this method you should access the track from the step object:
G4Track *aTrack = aStep->GetTrack();
// Then you should get the KineticEnergy of the track if the process is
// "Compton scattering" and if the volume remains the same in the next step.
// See the code lines below:
G4StepPoint* preStepPoint = aStep->GetPreStepPoint();
const G4VProcess* CurrentProcess = preStepPoint->GetProcessDefinedStep();
if (CurrentProcess != 0)
{
// To implement the next line, one needs to include " #include "G4VProcess.hh" "
// (See SteppingAction.cc in TestEm6)
const G4String & StepProcessName = CurrentProcess->GetProcessName();
// Get track ID for current processes
G4double TrackID = aStep->GetTrack()->GetTrackID();
if( (StepProcessName == "pol-compt")&&(TrackID==1) )
{
// processing hit when entering the volume
G4double kineticEnergy = aStep->GetTrack()->GetKineticEnergy();
auto EkinUnits = G4BestUnit(kineticEnergy, "Energy");
// Get energy in units of keV
G4double En = kineticEnergy/keV;
// Determine angle in radians
G4double thetaRad = std::acos( 2- 511/En );
// Place condition to reject Compton scattering at 0 rad.
// (This is to avoid nan results when dividing through by 2pisin(theta))
if ( (thetaRad > 0) && (thetaRad < pi))
{
// fill histogram id = 13 (angular spread (in radians) as a function of scattering angle)
// analysisManager->FillH1(13, thetaRad);
// get particle name that's undergone the Compton scattering
G4String ParticleName = aStep->GetTrack()->GetParticleDefinition()->GetParticleName();
// Find position (c.f. /examples/extended/medical/GammaTherapy) in CheckVolumeSD.cc
// G4ThreeVector pos = aStep->GetPreStepPoint()->GetPosition();
// G4double z = pos.z();

How to open an uploaded file in another template - Django?

<p>my django app acts as an emailing service, emails that are sent are view-able and it's possible to send html emails. How do I display the html emails on the view-mail page rather than just displaying the name of the file ? (the following is the mail-view for an html email): <a href="https://i.stack.imgur.com/Pzdt4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Pzdt4.png" alt="enter image description here"></a></p>

Reaching the end of an array with a sequence of odd/even jumps
|
<p>I'm trying to understand a Python solution to a programming puzzle that seems to use dynamic programming. I am able to follow most of the solution, but I'm struggling a bit to really formalize the solution.</p>
<p>The problem is stated as follows:</p>
<blockquote>
<p>You are given an integer array <code>A</code>. From some starting index, you can
make a series of jumps. The (1st, 3rd, 5th, ...) jumps in the series
are called "odd" numbered jumps, and the (2nd, 4th, 6th, ...) jumps in
the series are called even numbered jumps. </p>
<p>You may jump <strong>forward</strong> from index <code>i</code> to index j (with <code>i < j</code>) in the following way: </p>
<ul>
<li><p>During <strong>odd</strong> numbered jumps (ie. jumps 1, 3, 5, ...), you jump to the index <code>j</code> such
that <code>A[i] <= A[j]</code> and <code>A[j]</code> is the <strong>smallest</strong> possible value. If there
are multiple such indexes <code>j</code>, you can only jump to the smallest such
index j. </p></li>
<li><p>During <strong>even</strong> numbered jumps (ie. jumps 2, 4, 6, ...), you jump
to the index <code>j</code> such that <code>A[i] >= A[j]</code> and <code>A[j]</code> is the <strong>largest</strong> possible
value. If there are multiple such indexes <code>j</code>, you can only jump to the
<strong>smallest</strong> such index <code>j</code>.</p></li>
<li><p>It may be the case that for some index <code>i</code> are <strong>no legal</strong> jumps.</p></li>
</ul>
<p>A starting index is <strong>good</strong> if, starting from that index, you can reach the end of the array by jumping some number of times (possibly 0 or more than once.) </p>
<p>We ask that you return the number of <strong>good starting</strong> indices.</p>
</blockquote>
<p>Below I show a solution in Python to this problem that a few authors have published. I understand how it builds <code>oddnext</code> and <code>evennext</code> and what these arrays technically hold (the index location one jumps to from that index with an odd or even jump). What I don't understand is how the last loop works, and what's the precise dynamic programming formulation behind it.</p>
<pre><code>def odd_even_jumps(self, A):
N = len(A)
def make(B):
ans = [None] * N
stack = [] # invariant: stack is decreasing
for i in B:
while stack and i > stack[-1]:
ans[stack.pop()] = i
stack.append(i)
return ans
B = sorted(range(N), key = lambda i: A[i])
oddnext = make(B)
B.sort(key = lambda i: -A[i])
evennext = make(B)
odd = [False] * N
even = [False] * N
odd[N-1] = even[N-1] = True
# Why does this loop start from the end?
for i in range(N-2, -1, -1):
if oddnext[i] is not None:
odd[i] = even[oddnext[i]]
if evennext[i] is not None:
even[i] = odd[evennext[i]]
return sum(odd)

NoMethodError in Admin::ApartmentPostsController#create
|
<p>I am using active admin for my admin panel in Ruby on Rails website. I have this code on my ApartmentPost resource.</p>
<pre><code>ActiveAdmin.register ApartmentPost do
permit_params :title, :max_stay, :min_stay, :bed_configuration, :number_of_guests,
:features, :description, :admin_user_id, :apartment_number,:latitude, :longitude, :clean_fee, :country, :location, photos: []
form(html: { multipart: true }) do |f|
f.inputs do
f.input :title
f.input :max_stay
f.input :min_stay
f.input :bed_configuration
f.input :number_of_guests
f.input :features
f.input :description
f.input :country
f.input :location
f.input :apartment_number
f.input :latitude
f.input :longitude
f.input :clean_fee
f.input :admin_user_id, as: :hidden, input_html: {value: current_admin_user.id}
f.file_field :photos, multiple: true
end
f.actions
end
</code></pre>
<p>So the error I am getting is while creating a new ApartmentPost. The error is:</p>
<p><a href="https://i.stack.imgur.com/Lpvl2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Lpvl2.png" alt="enter image description here"></a></p>
<p>I had created a column called rate in AparmentPost but now it is already removed. Still it gives this error.</p>
<p>Here's the table from schema.rb:</p>
<pre><code>create_table "apartment_posts", force: :cascade do |t|
t.integer "admin_user_id", null: false
t.integer "max_stay", null: false
t.string "bed_configuration", null: false
t.integer "number_of_guests", null: false
t.string "features", null: false
t.string "description", null: false
t.json "photos"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.string "title", null: false
t.string "country", null: false
t.string "apartment_number", null: false
t.string "latitude"
t.string "longitude"
t.integer "min_stay", null: false
t.string "location", null: false
t.integer "clean_fee", default: 100, null: false
t.integer "property_type_id"
t.index ["admin_user_id"], name: "index_apartment_posts_on_admin_user_id", using: :btree
t.index ["property_type_id"], name: "index_apartment_posts_on_property_type_id", using: :btree
end
</code></pre>
<p>Here's the code in routes.rb</p>
<pre><code>devise_for :admin_users, ActiveAdmin::Devise.config
ActiveAdmin.routes(self)
</code></pre>
<p>I am new in Rails and Active Admin. I tried searching the solution everywhere even tried uninstalling active_admin gem and installing again and removing apartment_post resource and generating it again but none og them worked. </p>

Recursive join count - Oracle
|
<p>I have this Oracle db structure (something like forum, ok):</p>
<pre class="lang-sql prettyprint-override"><code>CREATE TABLE sections
(
section_id INTEGER NOT NULL ,
parent_section INTEGER NULL ,
section_name VARCHAR2(256) NOT NULL ,
section_desc VARCHAR2(1024) NULL
);
</code></pre>
<pre class="lang-sql prettyprint-override"><code>CREATE TABLE topics
(
topic_id INTEGER NOT NULL ,
topic_name VARCHAR2(256) NOT NULL ,
section_id INTEGER NOT NULL
);
</code></pre>
<pre class="lang-sql prettyprint-override"><code>CREATE TABLE messages
(
msg_id INTEGER NOT NULL ,
msg_text CLOB NOT NULL ,
topic_id INTEGER NULL ,
msg_date DATE NOT NULL ,
user INTEGER NOT NULL
);
</code></pre>
<p>As you can see, <code>sections</code> have hierarchical structure (by <code>parent_section</code> column).</p>
<p>I want to make two queries:</p>
<ol>
<li>Get topics count in section by section id, considering all child sections.</li>
<li>Same with messages instead of topics.</li>
</ol>
<p>Ok, I'm trying to write first query, but even it doesn't work (return wrong count without errors), I have no idea why:
</p>
<pre><code>SELECT si, t.TOPIC_ID, COUNT(*)
FROM (
SELECT s.SECTION_ID si
FROM SECTIONS s
START WITH SECTION_ID = :sectionId
CONNECT BY PRIOR SECTION_ID = PARENT_SECTION
)
LEFT JOIN TOPICS t ON t.SECTION_ID = si
GROUP BY t.TOPIC_ID, si
</code></pre>
<p><strong>EDIT:</strong>
While I'm setting up SQL Fiddle, I got some solution.</p>
<p>Firstly, we should use <code>INNER JOIN</code> instead of <code>LEFT JOIN</code>, because we don't need records with <code>null</code> <code>topic_id</code>.</p>
<p>Secondly, query with <code>COUNT()</code> was wrong, it just returns same records with additional column <code>COUNT</code> with <code>1</code> value. Now I just use <code>SUM(1)</code>:
</p>
<pre><code>SELECT SUM(1)
FROM (
SELECT s.SECTION_ID si
FROM SECTIONS s
START WITH SECTION_ID = :sectionId
CONNECT BY PRIOR SECTION_ID = PARENT_SECTION
)
INNER JOIN TOPICS t ON t.SECTION_ID = si
GROUP BY 1
</code></pre>
<p><strong>But it still not ideal solution</strong>, if we pass section without topics as <code>START WITH SECTION_ID =</code> argument, we will get nothing as answer. It requires additional check in program for prevent <code>NullPointerException</code>.</p>
<p>Maybe someone know, how can we get <code>0</code> as answer in this case?</p>

pyzmq Segmentation fault on large .recv()
|
<ul>
<li>edited - I think I wrongly pointed the blame at pyzmq - I actually was running in a QThread and upon suggestion worked on a full working example - not using QThread and I do not see any issues. I'm going to drop my working example for anyone who may want to reference this example. </li>

<p>I'm attempting to publish data on a <strong><code>pyzmq</code></strong> socket. I have experience here but never for larger data.

Excel (macro): understanding code - get unique values (rows & cols) to use in macro
|
<p>(First, I understand that <a href="https://stackoverflow.com/questions/15799172/use-vba-to-get-unique-values-for-use-within-vba">this</a> may work well for me - I'm trying to understand what's going on with a piece of code from somewhere else.)</p>
<p>I have a macro connected to buttons to hide columns and rows in range "rHFilter" that do not contain the value I want (whatever is in the drop-down in cell "M2"). To get the values for the drop-down, I am trying to check all the values in my range "rHFilter".
<a href="https://i.stack.imgur.com/PMsDz.png" rel="nofollow noreferrer">enter image description here</a></p>
<p>I'm getting <s>duplicates in my code</s> <em>multiple instances of values in my "strFilter" variable</em>, though, and I don't understand what this bit is doing, exactly, that it allows duplicates:</p>
<pre><code> For Each c In Range("rHFilter").Cells
If Application.CountIf(Range(Cells(3, 2), c), c.Value) = 1 Then
strFilter = strFilter & "," & c.Value
End If
Next c
</code></pre>
<p>That seems to be the smallest way to get unique values from a range to use in my macro - but if I can't make it work, I'm looking at trying the "collection" code from the other page. Can anyone help me?</p>
<p>As an aside, I don't understand what this is doing, either:</p>

php mail attachment - error - how to debug
|
<p>I search and try different methods to produce a php mail with an attachment, which is saveable with the Client (Outlook). It doesn't work porper and I don't know why?</p>
<p>If the script send the mail with this code:</p>
<pre><code> $result = mail($mail_to, $subject, $headers);
</code></pre>
<p>I got an email with an inline base64 coded attachment and if use it in this way:</p>
<pre><code> $result = mail($mail_to, $subject, "", $headers);
</code></pre>
<p>or</p>
<pre><code> $result = mail($mail_to, $subject, $text, $headers);
</code></pre>
<p>I got the PHP Error: "false" - the mail could not send.</p>
<p>So it isn't and Mailserverproblem, I think and from headersview I think, it should work and I get no mail error on the Linux site.</p>
<p>A part from the mail coming with the attachment inline:</p>

Trying to match email address and error message in non-delivery report
|
<p>I'm attempting to write a csharp app which parses NDRs (non-delivery reports) sent when an email is un-deliverable. The goal is to unsubscribe email addresses from our mailing lists which are no longer valid.</p>
<p>I've managed to write code which connects to our exchange server using the exchange web services API (EWS). Grabs the message body and what I want to do is match the email address and error code so that we can generate a report of email addresses and errors for manual review.</p>

<p>I am trying to come up with a regular expression that will match the email address that was sent to, and the accompanying error message.</p>
<pre><code> // First we set the input string.
string body = message.Body.Text;
// Regex string
Regex emailregex = new Regex("^<p>(.+?)</a><br>$");
var match = emailregex.Match(body);
if (match.Success)
Console.WriteLine(match.Groups[1].Value);
// Regex string
Regex errorregex = new Regex("</a><br>\n(.+?)<br>$");
match = errorregex.Match(body);
if (match.Success)
Console.WriteLine(match.Groups[1].Value);
</code></pre>
<p>Neither of the regular expressions I setup appear to not be working. I'm not much of a regular expression guru. Can anyone point me in the direction of what I'm doing wrong? </p>
<p>Thanks

How do I add transitions between images in an array
|
<p>Just wanted to know how I could add any transitions, like crossfade or slider, between each image in the array when I click the next button and the previous button. I thought of using JQuery but I've no idea how to implement it into this script was given this and told to add transitions between images for homework. Searched all over the internet but most of them are overlaying images and fading the top into the other and none of them uses array so I didn't know how to integrate it into this code would be nice if someone can give some advice :D<br>

Unity IAP - how to restore my Android purchases
|
<p>I made an Android payment system with IAP and it is currently registered in the App Store. However, a customer paid for the product and used it, but when I turned on the app again, the payment disappeared and the payment was proceeded again, and the window said, "It's an item I already have," and I couldn't pay.</p>
<p>So we need to add payment restoration function, but the official document and googling don't have an accurate restoration method. The only way to find it is old ways and errors I need to add a restoration function as soon as possible. How can I do this? I added the corresponding payment code below UNI.T version is 2021.3.3f1</p>
<p>Also, I added a script to the IAP button using OnPurchaseComplete without IStoreListener and proceeded with the payment, and I would like to recover it. They're all non-consumable products.</p>

<p>I am using asmack-android-8-4.0.6.jar as library for xmpp ,i was able to connect with earlier versions of asmack lib ,but with this new latest lib i am getting below exception,please help me out how to enable SSL authentication using latest asmack lib ,
I don't find connConfig.setSASLAuthenticationEnabled(true); method in latest lib</p>
<pre><code> ConnectionConfiguration connConfig = new ConnectionConfiguration(HOST,PORT);
//connConfig.setSASLAuthenticationEnabled(true);
// connConfig.setCompressionEnabled(true);
connConfig.setSecurityMode(SecurityMode.enabled);
connConfig.setDebuggerEnabled(true);
connConfig.setSocketFactory(new DummySSLSocketFactory());
connection = new XMPPTCPConnection(connConfig);
try {
connection.connect();
Log.i(TAG, "Connected to " + connection.getServiceName());
} catch (XMPPException ex) {
Log.e(TAG, "Failed to connect to " + connection.getHost());
Log.e(TAG, ex.toString());
return null;
//setConnection(null);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();

<p>these is my program i need to output "game over" if the user enter the string no instead of yes, right now it only works with the yes but i dont know how to add the other option the game is suppose to ask the user for a seed , then for a number from 1 to 100 and then the user has to guees the number, once the user guesses the number it asks if it wants to play again, with option of yes or no, i have the yes but i dont know how to output the no.</p>

All words used to used to train Doc2Vec model appear as unknown

<p>I'm trying to make an unsupervised text classifier using Doc2Vec. I am getting the error message of "The following keywords from the 'keywords_list' are unknown to the Doc2Vec model and therefore not used to train the model: sport". The rest of the error message is super long but eventually ends with "cannot compute similarity with no input" which leads me to believe that all of my keywords are not accepted.</p>

<p>I have a struct called <code>member</code>. Within <code>member</code> I have a <code>std::string</code> array called <code>months</code> that I would like to initialize to default values. This is how I am doing it currently:</p>
<pre><code>template <typenameT>
struct member
{
std::string months[12];
std::string name;
T hours_worked[12];
T dues[12];
member() : months{"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"} {};
};
</code></pre>
<p>However, whenever I compile I get this warning message:</p>
<pre><code>warning: extended initializer lists only available with -std=c++0x or -std=gnu++0x
</code></pre>
<p>How can I do the initialization properly and get rid of this error message?</p>
<p><strong>Edit:</strong></p>
<p>I should of made my question more clear. I need compile this program on a older compiler and the <code>-std=c++0x</code> flag option will not be available to me. How can I do this correctly without using the flag.</p>

Filtering a dataframe based on numerical values in a column
|
<p>I am trying to filter the rows in a dataframe based on the values of a column. If the numerical value is above 2, then it takes those rows, if it is below 2 it should not take those rows.
Sample dataframe</p>
<pre><code>| Number | Machine Name | Number of jobs|
|:-------|:------------:| -------------:|
| One | Power Drill | 1 |
| Two | Wench | 3 |
|Three | Screwdriver | 9 |
</code></pre>
<p>Desired outcome: The code should look at the third column "Number of jobs" and see if the number is greater than 2 then it should take it, else it should ignore it.
This is my code:</p>
<pre><code>import pandas as pd
import openpyxl
import glob
import os
source_folder = r'C:\Users\Ahmed_Abdelmuniem\Desktop\YYY'
file_names = glob.glob(os.path.join(source_folder, '*.xlsm'))
target_file = 'XXX.xlsm'
table_2 = pd.read_excel(target_file)
job_list = [3,4,5,6,7,8,9,10]
new_df = table_2['Number of jobs'].isin(job_list)
</code></pre>
<p>I am getting the following error:</p>
<pre><code>C:\Users\Ahmed_Abdelmuniem\AppData\Local\Programs\Python\Python39\python.exe "C:/Users/Ahmed_Abdelmuniem/PycharmProjects/Rig Visualisation/main.py"

File "pandas\_libs\hashtable_class_helper.pxi", line 4562, in pandas._libs.hashtable.PyObjectHashTable.get_item
KeyError: 'Number of jobs'
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "C:\Users\Ahmed_Abdelmuniem\PycharmProjects\Rig Visualisation\main.py", line 57, in <module>
new_df = table_2['Number of jobs'].isin(job_list)

raise KeyError(key) from err
KeyError: 'Number of jobs'
Process finished with exit code 1
</code></pre>
<p>Edit: Upon further investigation I discovered the following:</p>
<pre><code> Unnamed: 0 Unnamed: 1 Unnamed: 2 Unnamed: 3
0 NaN Number Machine Name Jobs
1 NaN 1 Power Drill 1
2 NaN 2 Wench 4
3 NaN 3 Screwdriver 5
</code></pre>
<p>It seems that pandas is not reading the column names, but rather it is reading them as unnamed, why is that?</p>

How to automatically call for a next iterator inside a loop
|
<p>I recently started scripting and am having difficulties with nested loops. I'm not getting the first iterator object from the first loop as an input to the second to run properly.</p>
<p>The problem itself is quite simple. I would like to change the second item (‘20’) on row 1 in my data to a number from the range and create a file.
So if the first number from the range is 14 then the first line of the file is (L,14,0,0,0,0) and gets a name data1.txt.</p>
<p><strong>Data:</strong></p>
<p>L,1,5.827,20,-4.705,0<br>
L,20,0,0,0,0<br>
L,12,15,0,-6,0</p>
<p><strong>Original Script:</strong></p>
<pre><code>import re
from itertools import islice
import numpy as np
x = np.arange(14,30.5,0.5)
size = x.size
with open('data.txt', 'r') as line:
for line in islice(line, 1, 2):
re.sub(r'\s', '', line).split(',')
nline = line[:2] + line[3:]
x = iter(x)
y = next(x)
for i in x:
nline = nline[:2] + str(y)+ nline[3:]
with open('data.txt', 'r') as file:
data = file.readlines()
data[1] = nline
for i in range(1,size):
with open('data%i.txt' %i, 'w') as file:
file.writelines(data)
</code></pre>
<p>EDITED:</p>
<p>Ive made some progress with my script and Im almost there. </p>
<p>After the first loop I have the output that I need (33 cases). All I would like to do now is to write them to a 33 unique files, named data1 to data33. What seems to happen however is that the second loop iterates through the first loop another 33 times and creates 1089 cases. So what ends up in the files is only the last line of the first loop. </p>
<p>Any suggestions how to allow the second loop for file creation but disable it for data? </p>
<p><strong>Updated Script:</strong></p>
<pre><code>import re
from itertools import islice
import numpy as np
x = np.arange(14,30.5,0.5)
size = x.size
with open('data.txt', 'r') as line:
for line in islice(line, 1, 2):
re.sub(r'\s', '', line).split(',')
for i in x:
y=str(i)
nline = line[:2] + y + line[4:]
with open('data.txt', 'r') as file:
data = file.readlines()
data[1] = nline
for i in range(1,size+1):
with open('data%i.txt' %i, 'w') as file:
file.writelines(data)
print data

Why the params go through the function when i use junit?

}
List<HOSStatusEvent> statusEvents = JSON.parseArray(JSON.toJSONString(params.get("statusEvents")),

Storing HTML Form input as an Object using a Constructor class and a dynamic variable name (Plain JS)
|
<pre><code><form id="projectForm" onsubmit="return ptitle.value = new Project(this);">
<div class="form-row">
<label for="ptitle">Title: </label>
<input type="text" id="ptitle" name="ptitle"><br>
</div>
<div class="form-row">
<label for="pdescription">Discription: </label>
<input type="text" id="pdescription" name="pdescription"><br>

<div class="form-row">

</form>
</code></pre>
<p>So I would like to take the data submitted from this form and call a constructor method within the Projects class. I'd also like to be able to dynamically generate the variable name from the title value of the form. Here's the JavaScript code. I'll need to use plain JS as that is what's required for the project! We're also required to use a constuctor class or factory function to generate the projects. As you can see I've tried to take a stab at it but unfortunately it hasn't worked. Thanks in advance.</p>
<pre><code>class Project {
constructor(form) {
this.title = form.ptitle.value;
this.description = form.pdescription.value;
this.dueDate = form.pdueDate.value;
this.priority = form.priority.value;
}
todoList = {};
addTodoList(value, description) {
this.todoList[value] = description;
}
removeTodoList(key) {
delete this.todoList[key];
}
}
</code></pre>
<p>Thanks again!!!</p>

Exception Unhandle System.IndexOutOfRangeException
|
<p>This code is about viewing a published consultation schedule. Unfortunately I'm stuck with the if statement. The error occurs at line : If dr("Lecturer") = ComboBox2.SelectedItem Then || I'm using a combobox to display the data from a database, which means there is a list of items in the combobox, and I will select any lecturer so it will display into the form. I have a database that contained the published schedule inside as shown at the pic. And all data stored in here(database) are actually unavailable(declared as red=unavailable, lime=available), except for the available does not stored into the database. So, what I'm doing now is to read and match the "Time", "Available" and "Lecturer" from the database, and change it to (red color) into the respective label(in lime colored).</p>

Node.js ffmetadata incorrect codec parameters
|
<p>I'm making a song downloader app in Node.js. I managed to get everything to work, the app downloads the song and downloads its artwork (image). So I have the mp3 file and jpg file. The only problem is attaching the jpg file to the mp3 file.</p>
<p>I'm using the ffmetadata node.js module. I downloaded and installed its dependency "ffmpeg" cli.</p>
<p>Now when I try to write the metadata to the mp3 file and attach the artwork it spits this error:</p>
<pre><code>Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
</code></pre>
<p>My code:</p>
<pre class="lang-js prettyprint-override"><code>ffmetadata.write('test.mp3', {}, {attachments: ['test.jpg']}, function(err) {
if (err) console.error(err);
});
</code></pre>
<p>The error:</p>

change JDK version in octave on mac
|
<p>Octave 3.8.2, OS X 10.10.4</p>
<p>I used</p>
<pre><code>ml_jar_version=javaMethod('getProperty','java.lang.System','java.version');
ml_jar_version=['Java ' ml_jar_version];
</code></pre>
<p>to check the java version and I got</p>
<pre><code>ml_jar_version = Java 1.6.0_65
</code></pre>
<p>However, I want Octave to use JDK 1.7 and so I typed</p>
<pre><code>setenv("JAVA_HOME","/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home");
</code></pre>
<p>but <code>ml_jar_version</code> did not change.</p>
<p><strong>My question</strong> is: how to make Octave to use JDK 1.7?</p>
<p><strong>Edit 1</strong>: my Octave was installed through homebrew. I believe homebrew just downloaded precompiled binaries. The following is the configuration of my Octave installation:</p>

Bluehost MySQL and phpmyadmin select sql service.php running slow while insert, delete, and update commands works instantly
|
<p>I am using crud commands in an app and my commands for insert, delete and update in sql work instantly. The select query in my php file called service loads in a few hours. I was wondering what was causing this. It doesn't really make since to me considering the other commands work instantly. Besides it not loading in my app I have it in a website where I can view my table with the php file. This does not load either...</p>
<p>I have my service on a website secured with HTTPS, is there anything on bluehost that I need to change in settings? I also posted my code below for my php file. I've tried a few other coded formats and commented these out of which none work anyway. This leads me to believe this is some setting in bluehost. Anyone else with the same problems and found a solution they could share or any ideas of why this is happening?</p>

Why gstreamer with vaapih264enc shows "context pad peer query failed"?
|
<p>I would like to use hardware encoding to compress a raw video file using gstreamer and vaapi. I am getting <code>Could not initialize supporting library</code>, which does not allow encoder to open. Possibly <code>context pad peer query failed</code> is the root cause for this. But I am not sure. I use the following pipeline:</p>
<pre><code>gst-launch-1.0 -v filesrc location=input.raw ! videoparse width=1280 height=1024 format=yuy2 framerate=20/1 ! vaapih264enc ! h264parse ! qtmux ! filesink location=compressed.mov
</code></pre>
<p>Pipeline fails with message:</p>
<pre><code>Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstVaapiEncodeH264:vaapiencodeh264-0: Could not initialize supporting library.

Python Crash Course -Alien Invasion -Game Ending Error
|
<p>I am working on the Alien Invasion project at the end of Python Crash Course 2nd Edition and I am having a problem with my game ending after the user runs out of lives. The game is supposed to end after all 3 lives are lost but when that happens for mine the aliens continue to move off the bottom of the screen. There are no error messages and from my many checks through the code I have entered it word for word from the book. I have worked up to the section where the scoreboard is added but now I am resetting the scoreboard which requires the game to end properly. Below is a copy of all the necessary code files that would apply to this issue. Each separate file is indicated by #filename.py and the code for said file follows. If there is anything else needed to check through this please let me know.</p>

Finding all object indices satisfying testing function, like array.findIndex() but more than first index

<p>I have an array of objects:</p>
<pre><code>var data = [{"district":"201","date":"Wed Apr 01 2020","paper":671.24,"mgp":36.5},

{"district":"203","date":"Wed Jan 01 2020","paper":607.85,"mgp":89.26}]
</code></pre>
<p>For each <code>district</code> I would like to take the values of <code>paper</code> and <code>mgp</code> for February, March, and April and divide each month's values by their January values to measure % change. </p>
<p>Using Array.findIndex() and reduce() (like <a href="https://stackoverflow.com/questions/30667121/javascript-sum-multidimensional-array">here</a>) I can match the districts and return the correct value, but that only returns the first index of the match, and there are repeat indices because there are subsequent months. I've tried wrapping a loop of months around the findIndex() to no avail: <code>console.log(result)</code> returns nothing</p>
<pre><code>var result = data.reduce((a, b) => {
var months = [...new Set(a.map(m => a.date))];
for (var month of months){
var idx = a.findIndex(e => e.district == b.district && e.date == month)
if (~idx && b.date === "Wed Jan 01 2020") {
a[idx].paper = a[idx].paper/b.paper;
a[idx].mgp = a[idx].mgp/b.mgp}
else {
a.push(JSON.parse(JSON.stringify(b)));
}
return a
}, []);
</code></pre>
<p>Result should look like this:</p>
<pre><code>[{"district":"201","date":"Wed Apr 01 2020","paper":1.17,"mgp":0.94},
{"district":"202","date":"Wed Apr 01 2020","paper":1,"mgp":1.99},
{"district":"203","date":"Wed Apr 01 2020","paper":1,"mgp":0.75},
{"district":"201","date":"Sun Mar 01 2020","paper":1,"mgp":1},
{"district":"202","date":"Sun Mar 01 2020","paper":1,"mgp":1.64},
{"district":"203","date":"Sun Mar 01 2020","paper":1,"mgp":0.77},
{"district":"201","date":"Sat Feb 01 2020","paper":1.17,"mgp":1},
{"district":"202","date":"Sat Feb 01 2020","paper":1,"mgp":1},

Woocommerce product subtitle is misplaced

<p>Hey everyone I hope you can help me with this.
I created 2 subtitles with ACF for my products (subtitle and subtitle_2)
I want them to appear underneath my Product title (duh!!) on both my product page, and my homepage/shop (in the product "little box").</p>
<p>So far I managed to have them appear on the product page, by editing my single-product.php file but they're not in the right spot and I have no idea how to move them to where I want. I think they're considered as subtitles of the Page title rather than subtitles if the Product title.
(and as for the homepage, they don't appear at all but let's sort out 1 problem at a time)</p>

django DB2 inspectdb failure :'NoneType' object is not subscriptable
|
<p>my dev environment is in python 3.6 and virtualenv(virtualenv 15.1.0) and with dependencies below:
django 2.2
ibm-db 3.0.1
ibm-db-django 1.2.0.0</p>
<p>as i used "(env_django2) λ python manage.py check", it return "System check identified no issues (0 silenced)." that is no problom.</p>
<p>however, when i used "python manage.py inspectdb --database db2 DEMO.DEMOUSER", it return like these below:</p>
<pre><code>(env_django2) λ python manage.py inspectdb --database db2 DEMO.DEMOUSER
# This is an auto-generated Django model module.
# You'll have to do the following manually to clean this up:
# * Rearrange models' order
# * Make sure each model has one field with primary_key=True
# * Make sure each ForeignKey has `on_delete` set to the desired behavior.
# * Remove `managed = False` lines if you wish to allow Django to create, modify, and delete the table
# Feel free to rename the models, but don't rename db_table values or field names.
from django.db import models
# Unable to inspect table 'DEMO.DEMOUSER'
# The error was: 'NoneType' object is not subscriptable
</code></pre>
<p>this is my db2 setting:</p>
<pre><code> DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
},
'db2':{
'ENGINE': 'ibm_db_django',
'NAME': 'test',
'USER': 'db2inst1',
'PASSWORD': 'XXXXXX',
'HOST': 'XX.XXX.XXX.XXX',
'PORT': 'XXXXX',
'PCONNECT':True,
}
}
</code></pre>
<p>and i had test it by coding like these below, and that is no problom.</p>
<pre><code>with connections['db2'].cursor() as cursor:
cursor.execute("""
select * from DEMO.DEMOUSER
""")
columns = [col[0] for col in cursor.description]
listResult = [dict(zip(columns, row)) for row in cursor.fetchall()]
print(listResult)
</code></pre>
<p>so my question is how can i make the inspectdb work?</p>
<p>i have check inspectdb.py, and i found that </p>
<pre><code>table_description = connection.introspection.get_table_description(cursor, table_name)
except Exception as e:
yield "# Unable to inspect table '%s'" % table_name
</code></pre>
<p>func get_table_description will invole the code below:</p>
<pre><code>sql = "SELECT TYPE FROM SYSIBM.SYSTABLES WHERE CREATOR='%(schema)s' AND NAME='%(table)s'" % {'schema': schema.upper(), 'table': table_name.upper()}
</code></pre>
<p>it seem i didn't set the table and schema name right.</p>
<p>ok, i have to go to sleep, very tired.</p>
<p>2020.3.13 update........</p>
<p>so when i readed the code in ibm_db_django\introspection.py, i found that below:</p>
<pre><code>schema = cursor.connection.get_current_schema()
</code></pre>
<p>that mean, ibm_db_django will get the schema by default, which is your user name setted in django's setting file. so it will always set the table name like 'db2inst1.DEMO.DEMOUSER' in my case. u can't change the schema by yourself.</p>
<p>as i know, setting the schema immutable is unreasonable,because the schema and user was different things in db2 unlike oracle. everyone can use the granted schema.</p>
<p>hence, i had to change the code like these,so that i can set my schema correctly:</p>
<pre><code># change the code below
#schema = cursor.connection.get_current_schema()
print( '-----------change by HK 20200313-----------------')
if len(table_name.split('.')) == 2:
cursor.connection.set_current_schema(table_name.split('.')[0].upper())
table_name = table_name.split('.')[1]
schema = cursor.connection.get_current_schema()
print('----------------- HK TEST schema:%s'%schema)
# change the code below
#cursor.execute( "SELECT * FROM %s FETCH FIRST 1 ROWS ONLY" % qn( table_name ) )
sql = "SELECT * FROM %s FETCH FIRST 1 ROWS ONLY" % ( schema+'.'+table_name )
print('------------ HK TEST LOG:%s'%sql)
cursor.execute( sql )
</code></pre>
<p>so the problem had been solved,however,another emerged !!
when i typed the command "python manage.py inspectdb --database db2 DEMO.DEMOUSER", it show below:</p>
<pre><code>class DemoDemouser(models.Model):
Traceback (most recent call last):

</code></pre>
<p>checking inspectdb.py，i find out the answer. the description of specified table ,returned from the func in introspection.py implemented by ibm_db_django, is different from inspectdb.py in django 2.2.</p>
<p>so check it with django release history and ibm_db_ango.
ibm_db_ango 1.2 released in 2018.4.3, django 2.2 released in 2019.3.</p>
<p>it seem django 2.2 dont support the ibm_db_ango 1.2(the latest version)</p>
<p>therefore i had to install django 2.0 instead. </p>
<p>finally it work!!!.</p>

How to make images fill my carousel slides
|
<p>I am trying to fit my images into the slides.</p>
<p>Below is my example code and screenshots:</p>
<pre><code><div className="relative h-24 w-20 sm:h-44 sm:w-100 md:h-44 md:w-60 flex-shrink-0">
<Carousel showThumbs={false}>
{imgSrc?.map((url, index) => (
<div className="h-24 w-20 sm:h-44 sm:w-100 md:h-44 md:w-60 flex-shrink-0" >
<img class="object-fill rounded-md" src={`${url}`} />
</div>
))}
</Carousel>
</div>
</code></pre>
<p><a href="https://i.stack.imgur.com/CbOSb.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CbOSb.png" alt="enter image description here" /></a>
<a href="https://i.stack.imgur.com/Yhscz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Yhscz.png" alt="enter image description here" /></a></p>

<a href="https://i.stack.imgur.com/g38KW.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/g38KW.png" alt="enter image description here" /></a></p>
<p>What I have done is:</p>
<ol>
<li><p>Set the first block into fix size. This is the size I want every image will be constrained into.</p>
</li>
<li><p>Inside the Carousel: Since the <code><div></code> and <code><img></code> tags are the protocol in this library. So I'm just following it.</p>
</li>
<li><p>To make sure everything will be constrained into fixed length. I set same CSS rule to every tag.</p>
</li>
</ol>
<p>The result is that not all images display the same size. Some have some empty space which I don't want to see.</p>
<p>May I know how to fix it? Isn't this the way of this CSS is intended to be used?</p>
<hr />
<p>[updated with Ed Lucas's code]</p>
<p>In MD setting, all the images in thumbnail are perfectly fitted into the box.</p>

Plotly animation with factors
|
<p>Converting a num vector to factors yields unexpected results in a plot_ly animation.</p>
<blockquote>
<p>If frame is a numeric variable (or a character string), frames are always ordered in increasing (alphabetical) order; but for factors, the ordering reflects the ordering of the levels <a href="https://plotly-book.cpsievert.me/key-frame-animations.html" rel="nofollow noreferrer">plotly book</a></p>
</blockquote>
<p>With the data set: </p>
<pre><code>>str(genTotal)
data.frame': 1620 obs. of 4 variables:
$ generation: int 0 0 0 0 0 0 0 0 0 0 ...
$ fitness : num 2.38 2.38 2.38 2.38 21.82 ...
$ x : num 0.946 0.946 0.946 0.946 -2.26 ...
$ x2 : num -0.0686 -0.0686 -0.0686 -0.0686 2.0935 ...
</code></pre>
<p>As expected the keyframes are sorted alphabetically:
<a href="https://i.stack.imgur.com/5w3mF.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5w3mF.png" alt="enter image description here"></a></p>
<hr>
<p>When converting <em>generation</em> to a factor as suggested, suddenly all frames are drawn on top of each other:</p>
<pre><code>genTotal$generation <- factor(genTotal$generation, ordered = TRUE)
'data.frame': 1620 obs. of 4 variables:
$ generation: Factor w/ 81 levels "0","50","100",..: 1 1 1 1 1 1 1 1 1 1 ...

Why are suddenly all frames drawn on top of each other? </p>
<p>How can I correctly (ordered) animate a plot_ly plot with a numeric frame vector?</p>

How to redirect to new screen for each dynamic grid view content?

<p>I have one grid view, and i am showing data from my database. So like say, if I have 6 titles.Then my grid view will be 6 (boxes ). Whenever I press each grid view title [ box ]. I need to redirect to separate 6 screen. How to do that?</p>
<p>So if I press my first title in my grid view. That is <code>Orders</code> I need to redirect to <code>order.html</code>, and if I press <code>Delivery</code> I need to redirect them to <code>Delivery.html</code>. How to do that?</p>

Scrapy Xpath construction producing empty brackets on dynamic site
|
<p>I am trying to create a spider via scrapy to crawl a website and extract all links for specific stores. Ultimately, the spider would then use those store links to extract pricing information. The site is designed to break down store information into States and Regions. I have been able to extract all sub links for the States/regions, but I cannot seem to extract the specific information for the stores, that information being the store links. </p>
<p>I thought it had to do with the page not being loaded long enough for those store links to display. So I used selenium and delayed the timing by 20 seconds to allow appropriate time for the webpage to load. An example link would be <a href="https://weedmaps.com/dispensaries/in/united-states/colorado" rel="nofollow">https://weedmaps.com/dispensaries/in/united-states/colorado</a> and as you can see on the left hand side there is information for specific stores. A snippet using the inspect element yields the following HTML: </p>
<pre><code><li class="ng-scope" ng-repeat="listing in listings" wm-listing-detail="" role="listing">
<div ng-class="{unpublished: !listing.published}">
<div class="listing feature-1 recreational dispensary" ng- class="featureClassesFor(listing)" ng-click="setActiveMarker(listing)">
<img class="avatar" ng-src="https://d2kxqxnk1i5o9a.cloudfront.net/uploads/avatars/dispensaries/5566/square_10569095_10152344322971376_2924814837799131094_n.jpg" src="https://d2kxqxnk1i5o9a.cloudfront.net/uploads/avatars/dispensaries/5566/square_10569095_10152344322971376_2924814837799131094_n.jpg"/>
<div>
<div class="name hovers">
<a class="ng-binding" href="/dispensaries/organic-alternatives" role="listing url" ng-bind-html="listing.name">Organic Alternatives</a>
</div>
</div>
<div class="address ng-binding">
<div class="wm_map_inactive_rating">
</code></pre>
<p>I am looking to extract the information following the @href.</p>
<p>I have the following python code in the spider section of the scrapy project:</p>
<pre><code>import scrapy
from scrapy.spider import BaseSpider
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
class scrapybotspider(scrapy.Spider):
name = "scrapybot_spider"
start_urls = ['https://weedmaps.com/dispensaries/in/united-states/colorado']
delay = 20
def __init__(self):
self.driver = webdriver.Firefox()
def parse(self, response):
self.driver.get(response.url)
while True:
StateCountyURL = response.xpath("//*[@id='wm-listings']/div/li[2]/div/div/div[1]/div/@href").extract()
print StateCountyURL
</code></pre>
<p>This produces empty brackets and I have tried a number of different xpath constructions.</p>

<p>I'm trying to make WebMQ act synchronously in MULE in order to turn the message queue into a REST api for an internal project. Unfortunately, I know very little about MULE.</p>
<p>After a good bit of work, I started understanding the Request-Reply scope and tried to use the WMQ Connector with it, only to find out that WMQ only sends once the flow has ended.</p>
<p>I've tried putting the request into a different flow using VM to trigger it<br>
<img src="https://i.imgur.com/PpLnNKu.png" alt=""></p>
<p>but so far that just leads to it waiting forever on WMQ that will never happen.</p>
<p>I've also tried using VMs for back and forth:<br>
<img src="https://i.imgur.com/yv4r9FB.png" alt=""></p>
<p>But it seems to do the same thing as without, where it just ignores the input.</p>
<p>Now I know the input and output for the WMQ are working, as I previously setup a flow that used http to communicate with itself and let it know when a message went through.</p>
<p><img src="https://i.imgur.com/aFOZYAE.png" alt=""></p>
<p>What I essentially want is this, but using HTTP instead of AJAX</p>
<p><img src="https://i.imgur.com/hXPLGAR.png" alt=""></p>
<p>My latest, and perhaps closest attempt looks like thus:

<p>Which almost works, but it hangs indefinitely without sending a response back to the HTTP server. Setting the vm:inbound-endpoint in the Request-Reply flow to one-way keeps it from hanging, but doesn't send the new payload that's been received, but instead the previous payload (as if it's being skipped over).</p>
<p>Any help at all would be greatly appreciated!</p>

How many iterations of the Mandelbrot set for an accurate picture at a certain zoom?
|
<p>I have implemented the mandelbrot set algorithm in Java which I am using to make an animation of zooming into the set. My problem is that the algorithm is performing very slowly since I have it set such that the maximum number of iterations is high (1000) so that clarity will be preserved when zooming in closely. However, when on a more zoomed-out picture, only around 100 iterations are required to have an accurate picture.</p>
<p><a href="https://media.giphy.com/media/C9lNldSBctIFpvmGXY/giphy-downsized-large.gif" rel="nofollow noreferrer"><img src="https://media.giphy.com/media/C9lNldSBctIFpvmGXY/giphy-downsized-large.gif" alt="The Mandelbrot set" /></a></p>
<p>My question is: is there some function <code>f(x)</code> such that for x screen width, clarity will be acceptable? (This only needs to be approximate since the definition of "clear" isn't itself very clear, but the trendline should follow the rate of increase of accuracy which follows the set itself)</p>
<p>Here is my current implementation of the algorithm:</p>
<pre class="lang-java prettyprint-override"><code> private double[] target = {-1.256640565451168862869, -0.382386428889165027247};
// Returns an integer RGB value (0xRRGGBB) representing the colour which should be drawn at a certain position on the screen
private int getMandleRGB(int x, int y, int w, int h) {
Complex c = new Complex();
c.r = lerp(lerp(-2, target[0], 1-zoom), lerp(1, target[0], 1-zoom), x/(double) w);
c.i = lerp(lerp(-1.5, target[1], 1-zoom), lerp(1.5, target[1], 1-zoom), y/(double) h);
Complex z = new Complex();
z.r = c.r;
z.i = c.i;
int i = 0;
for (i = 0; i < 1000; i++) {
z = Complex.add(Complex.multiply(z, z), c);
if (z.i*z.i+z.r*z.r > 4) {
double t = Math.log(i)/Math.log(1000d);
return (int) lerp((gradient[0] & 0xff0000) >> 16,
(gradient[1] & 0xff0000) >> 16, t)*0x10000
+ (int) lerp((gradient[0] & 0xff00) >> 8,
(gradient[1] & 0xff00) >> 8, t)*0x100
+ (int) lerp((gradient[0] & 0xff),
(gradient[1] & 0xff), t);
}
}
return 0x000000; // black

Java: Setting TLSv1.2 in https.protocols not working

<p>I am using <code>Java 7</code> with tomcat and trying to make an API call to paypal which only support <code>TLSv1.2</code> .

Error in `[.data.table`(Data, paste0(j, "_", i) == 1, `:=`(.(j), 0)) :
LHS of := must be a symbol, or an atomic vector (column names or positions).
</code></pre>
<p>My question here is if I can combine both double for loops into one without getting an error.
Also, because my dataset is bigger, any other faster implementation would be greatly appreciated.</p>
<p>Thank you.</p>

<p>I added the line</p>
<p><code>Plugin 'Valloric/YouCompleteMe'</code></p>
<p>to my .vimrc, afterwards the Vim command</p>
<p><code>:PluginInstall</code></p>
<p>executes without errors.</p>
<p>If I then start Vim the following error message is displayed:</p>
<p><code>The ycmd server SHUT DOWN (restart with ':YcmRestartServer'). Unexpected exit code -11. Type ':YcmToggleLogs ycmd_62275_stderr_menu0zqa.log' to check the logs.</code></p>
<p>The here mentioned log file is empty. Does anyone know what's the problem here?</p>
<p>I know there are a lot of other questions on StackOverflow and Github regarding very similar problems. But since I've spent the last 3 hours going through these and trying to get the plugin to work without success, I'd be happy if this won't be marked as duplicate and am very grateful for every response.</p>

Returning customize Array value
|
<p>I have a sample of code that returns each value in an array, in order. I have used <code>forEach()</code>. Is there any way to return value in customize array. </p>
<p>I made some function for split <code>text-area</code> value to all textarea and query using text string. I am able to success. But Some Problem. Below Example.</p>
<ol>
<li><p>Type to <code>Filed1</code> string like:
<br> <code>GFSD</code><br><code>65897542</code></p></li>
<li><p>Then Click Split Button. Output: part all value to reaming text area.</p></li>
<li><p>Put <strong>GF</strong> value to <strong>Input Character</strong> Filed. Output: <strong>6589</strong></p></li>
<li>My Question is When i put value like <strong>GF</strong> then output <strong>6589</strong>. And when put <strong>FG</strong> then also same output <strong>6589</strong> instead of <strong>8965</strong>. If any solution Pls help me out. I wish to the Character strictly follow number.</li>

How to reference more than one controller in one view (CakePHP)
|
<p>I am building an application in CakePHP (I have been using this for a couple of months in a new job, and took over this project from the previous employee, so my understanding is limited).</p>
<p>This application has several database tables, the ones involved in this problem are Centres, Softwares and Categories.</p>
<p>To give you a brief, hat I need, is when a user visits the 'Centres' view, to be able to have a list of all of the software below, and tick which the centres have access to.</p>
<p>To view a list of software, my SoftwaresController uses the function:</p>
<pre><code>public function view() {
$categories = $this->Software->Category->find ('list');
array_unshift ($categories, array('any' => 'Any'));
$this->set ('categories', $categories);
$this->Software->hasMany['Version']['limit'] = 1;
$this->Software->hasMany['Version']['fields'] = array('Version.id', 'Version.version_number', 'Version.created');
if ($this->request->is ('post') && $this->request->data) {
$conditions = array();
$filters = $this->request->data['Software'];
if (!empty($filters['name'])) {
$conditions['Software.name'] = $filters['name'];
}
if ($filters['category'] > 0) {
$conditions['Category.id'] = $filters['category'];
}
$this->paginate = array(
'conditions' => $conditions,
'order' => array(
'Software.latest_released' => 'desc',
'Software.name' => 'asc'
)
);
$this->set ('softwares', $this->paginate ());
$this->set ('paging', false);
} else {
$this->paginate = array(
'order' => array(
'Software.latest_released' => 'desc',
'Software.name' => 'asc'
)
);
$this->set ('paging', true);
$this->set ('softwares', $this->paginate ());
}
// This allows the user software page to show.
}
</code></pre>
<p>In the CentresController function, in which I want to be able to also view the data (as extracted above), looks like this:</p>
<pre><code>public function admin_view($id = null)
{
/* Centres */
$this->Centre->recursive = 0;
$this->Centre->id = $id;
if (!$this->Centre->exists()) {
throw new NotFoundException(__('This centre ID does not exist.'));
}
$centre = $this->Centre->read(null, $id);
$this->request->data = $centre;
$this->set('centre', $centre);
}
</code></pre>
<p>I have tried to combine the above two functions by adding the inside of view() into admin_view(). The view for admin_view() looks like this:</p>
<p>

Method not found: GraphQL.ExecutionOptions.set_NameConverter in netcoreapp2.2

<p>I need to integrate GraphQL in NetCoreApp 2.2 <code><TargetFramework>netcoreapp2.2</TargetFramework></code> (I can't upgrade to NetCore 3 for other reasons).</p>
<p>PS. We have another project in .Net Core 3.1 and we can use <em>GraphQL.Server.Transports.AspNetCore.SystemTextJson</em> and we don't have any problem. Everything works as expected in that project.</p>

Google App Engine and Java org.reflection library - Error during the scan procedure

<p>I'm trying to setup a <code>ConfigurationBuilder</code> for the library <code>Reflections</code>, which use the following configuration:</p>
<p>I'm using the library through a <a href="http://mvnrepository.com/artifact/org.reflections/reflections/0.9.10" rel="nofollow">Maven dependency</a></p>

<li>annotated with <code>@Annotation1</code> or <code>@Annotation2</code></li>
<li>declared in the package <code>package1</code>, <code>package2</code> or <code>package3</code></li>
<li>an extension of the class <code>SuperClass.class</code></li>
</ul>
<p>All the code is executed in a <code>ServletContextListener</code> (triggered and the start of the instance, of dev-server if localhost)</p>
<p>This is the code I managed to create</p>
<pre><code>ConfigurationBuilder configurationBuilder = new ConfigurationBuilder();
// Package filter
FilterBuilder scannerFilter = new FilterBuilder();
scannerFilter.includePackage("com.mypackage1");
scannerFilter.includePackage("com.mypackage2");
scannerFilter.includePackage("com.mypackage3");
configurationBuilder.filterInputsBy(scannerFilter);
// Select the proper location to scan
configurationBuilder.setUrls(Arrays.asList(ClasspathHelper.forClass(SuperClass.class)));
Reflections reflections = new Reflections(configurationBuilder);
// Get all the classes with annotation @Annotation1 or @Annotation2
Set<Class<?>> annotation1Classes = reflections.getTypesAnnotatedWith(Annotation1.class);
Set<Class<?>> annotation2Classes = reflections.getTypesAnnotatedWith(Annotation2.class);
</code></pre>
<p>but it does not works. This line</p>
<pre><code>Reflections reflections = new Reflections(configurationBuilder);

</code></pre>
<p>This code works, as long as I use a <code>main</code> method to test the code (which I did to quickly test various lines of code instead of run every time the App Engine dev-server).</p>
<p>But the same code, executed by the App Engine dev-server triggers the exception error that I already posted above.</p>
<p>Then... the problem seems to be related to the App Engine server and not strictly to the Reflection code.</p>
<hr>
<h2>EDIT2</h2>
<p>It is true that during the scan (with the App Engine environment) there is the exception throwned (many times I need to add, so many that the Eclipse console log cannot contains all the lines and it remove the oldest ones).</p>
<p>But those exception are not really thrown (a catch clause will be pointless) and at the end the scanner provides the correct classes.</p>
<p>At this point those exception seems to be only severe logs thrown by the <code>Reflections</code> constructor but they don't stop the execution of the server.</p>
<p>It remains only to understand why those exception are thrown, maybe it is related to the App Engine environment which block some inside feature of Java.</p>
<hr>
<h2>EDIT3</h2>
<p>I tried to deploy the application to see what kind of behaviour there is on the production enviroment.
Unlike the development environment (which logs a lot of severe exceptions) online there isn't any error logged but the scan result is 0 classes.</p>

Issues populating dictionary with float values from Excel Pandas
|
<p>I'm using an excel spreadsheet to populate a dictionary. Then I'm using those values to multiply the values of another data frame by reference, but it gives me errors when I try. I decided to make the excel spreadsheet out my dictionary to avoid errors, but I haven't been successful. I'm doing this because the dictionary eventually gets long and it's too tedious to edit the keys and its values. I'm using Python 2.7</p>
<pre><code>import pandas as pd
#READ EXCEL FILE
df = pd.read_excel("C:/Users/Pedro/Desktop/dataframe.xls")
#Store the keys with its value in a dictionary. This will become df2
d = {"M1-4":0.60,"M1-5/R10":0.85,"C5-3":0.85,"M1-5/R7-3":0.85,"M1-4/R7A":0.85,"R7A":0.85,"M1-4/R6A":0.85,"M1-4/R6B":0.85,"R6A":0.85,"PARK":0.20,"M1-6/R10":0.85,"R6B":0.85,"R9":0.85,"M1-5/R9":0.85}

ABAddressBookGetPersonWithRecordID return nil
|
<p>My app stores the AddressBook recordIds of Contacts with the same name and later tries to present the addresses to the user to select the desired person. However, when I use the stored recordIds with ABAddressBookGetPersonWithRecordID, it returns nil.
The code below represents the code project - I have "copied" the code that later tries to retrieve the Contact immediately below the code that stores the recordIds.</p>
<pre><code>NSString *full = person.compositeName;
CFArrayRef contacts = ABAddressBookCopyPeopleWithName(addressBook, (__bridge CFStringRef)(full));
CFIndex nPeople = CFArrayGetCount(contacts);
if (nPeople)
{
NSMutableArray *rIds = [[NSMutableArray alloc] init];
int numberOfContactsMatchingName = (int)CFArrayGetCount(contacts);
if (numberOfContactsMatchingName>1)
{
for ( int i=0; i<numberOfContactsMatchingName; ++i)
{
ABRecordID thisId = ABRecordGetRecordID(CFArrayGetValueAtIndex(contacts, i));
NSNumber *rid = [NSNumber numberWithInteger:thisId];
FLOG(@"%d Matched, this ID = %@", numberOfContactsMatchingName, rid);
[rIds addObject:rid];
}
for (int i=0; i<rIds.count; ++i)
{
//contactRecord = ABAddressBookGetPersonWithRecordID(addressBook, (ABRecordID)recId);
ABRecordRef contactRecord;
contactRecord = ABAddressBookGetPersonWithRecordID(addressBook, rIds[i]);
if (contactRecord)
{
}
else
{
FLOG (@"Noone found with recordId %@", rIds[i]);
}
}
</code></pre>
<p>So, for example, I just ran this, and it found two Contacts in the address book with the same name - with ids 143 and 305, but when I then tried ABAddressBookGetPersonWithRecordID with ids 143 and 305, both returned nil.
What have I got wrong here?</p>

Complicated Query + Pagination Script

Combining PCH, PDB, and Zi leads to puzzling C2859 compile error with VS2017
|
<p>I have a project that doesn't currently use precompiled headers, but I'd like to make it do so, as I've demonstrated that it leads to real compilation speed improvements in the project.</p>
<p>I'd also like to use <code>/Zi</code>, so I can capitalize on the parallel build benefits associated with <code>/Zf</code>, which is implied by <code>/Zi</code>.</p>
<p>I'm using the VS2017 C++ compiler, but I'm using a build system that is not Visual Studio, so answers relating to configuring VS aren't helpful. </p>
<p>What I'm finding is that I can set up the build to use precompiled headers just fine, or I can set it up to use <code>/Zi</code> just fine, but I can't seem to form a proper series of invocations to do both. When I try to do what I think is correct, I end up with error <code>C2958</code> stopping the build, and I don't see what I'm doing wrong.</p>
<p>I've built a toy project to demonstrate what I'm seeing. The <code>pch.hpp</code> header looks like this:</p>
<pre><code>#pragma once
#include <vector>
</code></pre>
<p>And we make a short mainline in <code>main.cpp</code>:</p>
<pre><code>int main() {
std::vector<int> xs = { 1, 2, 3 };
return xs.size();
}
</code></pre>
<p>Note that this is the complete file contents for <code>main.cpp</code>: I haven't omitted anything. I am intentionally <em>not</em> including <code>pch.hpp</code> here, because we are going to force inject it with <code>/Fi</code> later. The real project doesn't have include lines for a precompiled header in all the right places, and there would be thousands of files to update to do so. Note that the approach using <code>/Fi</code> does appear to work in the command lines below, and has the advantage that a forceincludes based mechanism can work with GCC style precompiled headers as well.</p>
<p>If we build things without <code>/Zi</code>, everything goes fine:</p>
<pre><code>cl /Fobuild\pch.obj /TP /nologo /EHsc /errorReport:none /MD /O2 /Oy- /Zc:rvalueCast /Zc:strictStrings /volatile:iso /Zc:__cplusplus /permissive- /std:c++17 /Zc:inline /c pch.hpp /Yc /Fpbuild\pch.pch
pch.hpp
cl /Fobuild\main.obj /c main.cpp /TP /nologo /EHsc /errorReport:none /MD /O2 /Oy- /Zc:rvalueCast /Zc:strictStrings /volatile:iso /Zc:__cplusplus /permissive- /std:c++17 /Zc:inline /FIpch.hpp /Yupch.hpp /Fpbuild/pch.pch
main.cpp
</code></pre>
<p>We find the files we would expect to find under the build directory:</p>
<pre><code>main.obj pch.obj pch.pch
</code></pre>
<p>However, if we try to use <code>/Fi</code> and <code>/Fd</code> to generate a per-file <code>.pdb</code> and control its name, it doesn't work at all:</p>
<p>We can compile the precompiled header that way OK:</p>
<pre><code>cl /Fobuild\pch.obj /TP /nologo /EHsc /errorReport:none /MD /O2 /Oy- /Zc:rvalueCast /Zc:strictStrings /volatile:iso /Zc:__cplusplus /permissive- /std:c++17 /Zc:inline /c pch.hpp /Yc /Fpbuild\pch.pch /Zi /Fdbuild\pch.pch.pdb
</code></pre>
<p>And things look OK in the <code>build</code> directory so far:</p>
<pre><code>pch.obj pch.pch pch.pch.pdb
</code></pre>
<p>But when we try to build the object file for main, it all falls apart:</p>
<pre><code>cl /Fobuild\main.obj /c main.cpp /TP /nologo /EHsc /errorReport:none /MD /O2 /Oy- /Zc:rvalueCast /Zc:strictStrings /volatile:iso /Zc:__cplusplus /permissive- /std:c++17 /Zc:inline /FIpch.hpp /Yupch.hpp /Fpbuild/pch.pch /Zi /Fdbuild\main.obj.pdb
main.cpp
main.cpp: error C2859: Z:\data\acm\src\example\build\main.obj.pdb is not the pdb file that was used when this precompiled header was created, recreate the precompiled header.
</code></pre>
<p>This is a very puzzling error, because the error message suggests that <code>main.obj.pdb</code> is being treated as an <em>input</em> somehow, but in fact it is intended to be the name of the <code>.pdb</code> file generated as <em>output</em>, per the value of the <code>/Fd</code> flag for the build of <code>main.obj</code>.</p>
<p>Googling hasn't resulted in much useful guidance, with a lot of hints about reconfiguring VS settings, which isn't really useful in the case of a build driven by something else.</p>
<p>I've also verified that my trickery with the <code>/Fi</code> of <code>pch.hpp</code> isn't the issue. If I update <code>main.cpp</code> to <code>#include pch.hpp</code> and remove the <code>/Fipch.hpp</code> from the compile line for <code>main.obj</code>, the same <code>C2859</code> error still occurs.</p>
<p>I realize there are a lot of flags to get right when using precompiled headers, among them the <code>/Yc</code> and <code>/Yu</code> and <code>/Fp</code> flags, but I think I've got those handled correctly.</p>
<p>Does anyone see where I've got things wrong?</p>
<p><strong>Edit 1 - Demonstrating that /Fd can name different PDB files</strong> </p>
<p>In response to the comment below, it doesn't actually appear to be the case that all targets must share the <code>/Fd</code> argument. Here is an example without the use of precompiled headers that demonstrates that:</p>
<p>Here, I've needed to add <code>common.cpp</code> and create a <code>main1.cpp</code> and <code>main2.cpp</code> which both link it:</p>
<p>The <code>common.hpp</code> header looks like:</p>
<pre><code>#pragma once
int common(int arg);
</code></pre>
<p>With a trivial implementation in <code>common.cpp</code>:</p>
<pre><code>#include "common.hpp"
int common(int arg) {
return arg + 42;
}
</code></pre>
<p>Then introduce two different mainlines:</p>
<p><code>main1.cpp</code>:</p>
<pre><code>#include "common.hpp"
int main() {
std::vector<int> xs = { 1, 2, 3 };
return common(xs.size());
}
</code></pre>
<p>And <code>main2.cpp</code>:</p>
<pre><code>#include "common.hpp"
int main() {
std::vector<int> xs = { 1, 2, 3, 4};
return common(xs.size());
}
</code></pre>
<p>Then compile all three object files. Note that we still have the <code>/Fipch.hpp</code> here to make the includes work right, but we aren't using any of the actual PCH machinery:</p>
<pre><code>cl /Fobuild\common.obj /c common.cpp /TP /nologo /EHsc /errorReport:none /MD /O2 /Oy- /Zc:rvalueCast /Zc:strictStrings /volatile:iso /Zc:__cplusplus /permissive- /std:c++17 /Zc:inline /FIpch.hpp /Zi /Fdbuild\common.obj.pdb
cl /Fobuild\main1.obj /c main1.cpp /TP /nologo /EHsc /errorReport:none /MD /O2 /Oy- /Zc:rvalueCast /Zc:strictStrings /volatile:iso /Zc:__cplusplus /permissive- /std:c++17 /Zc:inline /FIpch.hpp /Zi /Fdbuild\main1.obj.pdb
cl /Fobuild\main2.obj /c main2.cpp /TP /nologo /EHsc /errorReport:none /MD /O2 /Oy- /Zc:rvalueCast /Zc:strictStrings /volatile:iso /Zc:__cplusplus /permissive- /std:c++17 /Zc:inline /FIpch.hpp /Zi /Fdbuild\main2.obj.pdb
</code></pre>
<p>And we find what we would expect in the <code>build</code> directory:</p>
<pre><code>common.obj common.obj.pdb main1.obj main1.obj.pdb main2.obj main2.obj.pdb
</code></pre>
<p>Then we can go ahead and link:</p>
<pre><code>link /nologo /DEBUG /INCREMENTAL:NO /LARGEADDRESSAWARE /OPT:REF /OUT:build\main1.exe /PDB:build\main1.pdb build\common.obj build\main1.obj
link /nologo /DEBUG /INCREMENTAL:NO /LARGEADDRESSAWARE /OPT:REF /OUT:build\main2.exe /PDB:build\main2.pdb build\common.obj build\main2.obj
</code></pre>
<p>And we find that we get both executables and PDB files for those executables in the <code>build</code> directory:</p>
<pre><code>common.obj main1.exe main1.obj.pdb main2.exe main2.obj.pdb
common.obj.pdb main1.obj main1.pdb main2.obj main2.pdb
</code></pre>

How to keep the rails nested resource route url when model save fails?
|
<p><strong>Summary:</strong></p>
<p>I have a nested attribute. I go to route:</p>
<pre><code>/customers/:id/credit_cards/new
</code></pre>
<p>On the create action, save fails, code does </p>
<pre><code>render :new
</code></pre>
<p>This pushes the URL to:</p>
<pre><code>/credit_cards/new
</code></pre>
<p>How do I make sure the url stays with the customer route?</p>
<p><strong>Details:</strong></p>
<p>I want to use the following routes:</p>
<pre><code># Credit cards should be associated with a customer except
# potentially on initial creation:
resources :customers do
resources :credit_cards, only: [:index, :show, :new, :create, :edit, :update, :destroy, :show]
end
# Allow creating a credit card but selecting
resources :credit_cards, only: [:new, :create]
</code></pre>
<p>Basically a nested route for when a customer exists and a non-nested route for when I can create and assign a customer in the same view.</p>
<p>I have a single controller at</p>
<pre><code>app/controller/credit_cards_controller.rb
</code></pre>
<p>In the new and create action I check if I have a customer ID or not</p>
<pre><code>before_action :set_credit_card, only: [:show, :edit, :update, :destroy]
before_action :set_customer, only: [:index, :show, :create, :new, :edit, :update]
# GET /credit_cards/new
def new
@credit_card = if @customer
@customer.credit_cards.build rescue CreditCard.new
else
CreditCard.new
end
end
def create
@credit_card = CreditCard.new(credit_card_params)
respond_to do |format|
if @credit_card && @credit_card.save
format.html { redirect_to on_new_or_update_redirect_location, notice: 'Credit card was successfully created.' }
else
# HERE IS THE ISSUE: Figure out how to make sure the url stays as /customers/:id/credit_cards/new instead of /credit_cards/new
format.html { render :new }
end
end
end
</code></pre>
<p>When there is a validation failure, it re-renders the view, but pushes the URL to</p>
<pre><code>credit_cards/new
</code></pre>
<p>So I no longer am in the correct URL and customer_id is no longer a parameter. I assume if I can pass the customer_id it will do the right thing, but I have not found how to do that.</p>

UICollectionView How to implement horizontal align scrolling
|
<p>I have a <code>UICollection</code> which is implemented and works, however I cannot achieve the scrolling I want.</p>
<p>Here is a picture of my <code>UICollectionView</code>, I have resized the grey cell to <code>250</code> by <code>250</code>. </p>
<p><a href="https://i.stack.imgur.com/QHoWc.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QHoWc.png" alt="enter image description here"></a></p>
<p>My issue is, when I start scrolling, this is what happens. </p>
<p>My cell first starts off on the far left, but notice what happens if I start to scroll horizontally.</p>
<p><a href="https://i.stack.imgur.com/AN1f4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/AN1f4.png" alt="enter image description here"></a></p>
<p><a href="https://i.stack.imgur.com/aACAg.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/aACAg.png" alt="enter image description here"></a></p>
<p><a href="https://i.stack.imgur.com/Ygh2K.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Ygh2K.png" alt="enter image description here"></a></p>
<p>As you can see, the seam between the cells moves over to the left the more I scroll through the cells. This is not what I want. </p>
<p>What I want to achieve is: the cell is aligned to the center, and when you scroll, instead of the center of the cells moving to the left more and more, I want the cell to stay in the middle. Much like a <code>PageViewController</code> does except I want it to be <code>UICollectionViewCells</code>. </p>
<p>I have tried adding in the following code for example:</p>
<pre><code> - (void)scrollViewWillEndDragging:(UIScrollView *)scrollView withVelocity:(CGPoint)velocity targetContentOffset:(inout CGPoint *)targetContentOffset
{
float pageWidth = 210;
float currentOffset = scrollView.contentOffset.x;
float targetOffset = targetContentOffset->x;
float newTargetOffset = 0;
if (targetOffset > currentOffset)
newTargetOffset = ceilf(currentOffset / pageWidth) * pageWidth;
else
newTargetOffset = floorf(currentOffset / pageWidth) * pageWidth;
if (newTargetOffset < 0)
newTargetOffset = 0;
else if (newTargetOffset > scrollView.contentSize.width)
newTargetOffset = scrollView.contentSize.width;
targetContentOffset->x = currentOffset;
[scrollView setContentOffset:CGPointMake(newTargetOffset, 0) animated:YES];

<p>Which achieves the even scrolling, however I want to have <code>paging</code> enabled aswell as <code>bounce</code>. </p>
<p><a href="https://i.stack.imgur.com/ilEqE.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ilEqE.png" alt="enter image description here"></a></p>
<p>Because if I enable <code>paging</code> and <code>bounce</code>, the scrolling is very smooth and elegant, however If I use the code up above the scrolling is very rugged and mechanical.</p>
<p>So How can I achieve even scrolling that is smooth like apples default scrolling, with my <code>UICollectionViewCell</code> being centred in the middle?</p>
<p>If I didn't explain the problem well enough, this post <a href="https://stackoverflow.com/questions/13228600/uicollectionview-align-logic-missing-in-horizontal-paging-scrollview">here</a> explains my problem except I am using one cell instead of three, and I want the scrolling to be smooth and bounce etc.</p>

Is there any way to stop and then start a discord.py bot without having to restart the whole py file?
|
<p>According to discord.py's discord server as well as their docs you'd need to restart the whole py file after using 'bot.close()' since it disconnects from their api. Unfortunately I'm trying to create a launcher and it wouldn't really be ideal to restart the whole launcher to restart the bot, does anyone know any 'hacky' ways of starting up a discord.py bot after using 'bot.close()'? it doesn't have to be pretty, just needs to remotely work. Any suggestions/tips would be greatly appreciated.</p>
<pre><code> @asyncSlot()
async def on_btnStartBot_clicked(self):
self.pushButton_startBot.setEnabled(False)
if self.isBotRunning == False:
self.statusbar.showMessage("Starting Bot...")
try:
if isinstance(cfg["bot"]["token"], str) and cfg["bot"]["token"] != "":
await bot.start(cfg["bot"]["token"])
elif isinstance(cfg["bot"]["token"], list) and not all(token == "" for token in cfg["bot"]["token"]):
def first_token():
for t in cfg["bot"]["token"]:
if t != "":
return t
await bot.start(first_token())
else:
terminal.log("CRITICAL", f"No token was provided in '{utils.config.CONFIG_PATH}'")
except Exception as e:
self.statusbar.showMessage(str(e))
else:
self.statusbar.showMessage("Stopping Bot...")
await bot.close()
self.plainTextEdit_botTerminal.clear()
while not bot.is_closed():
print('Not Yet Closed')
if bot.is_closed():
print("Closed")
self.statusbar.showMessage("Bot Has Been Stopped...")
self.pushButton_startBot.setText("Start Bot")
self.isBotRunning = False
await asyncio.sleep(1)
self.pushButton_startBot.setEnabled(True)
