Url to the product after payment for subscription with Stripe in Django app
I've build Django app with authentication (Login/Sing up function). Then I created with Striple functionality to pay subscription for the product. In what way I can redirect user to the url with the product after payment? Does it require any special url/mechanism to activate the url after payment? I haven't yet created webhooks, is the mechanism of redirection to product url anyway related to webhooks implementation? -

How to open a DAL ( Django Autocomplete Light ) Select2 programmatically
I'm using DAL to render an autocomplete from a form field like this: search = forms.ChoiceField( widget=autocomplete.Select2( url='/search/my_search/', attrs={ 'data-placeholder': 'Select an option', 'data-minimum-input-length': 1, 'data-theme': 'bootstrap4', }) ) It gets rendered with this class: "select2-hidden-accessible" and gets this attr "data-autocomplete-light-function="select2". It doesn't get the "select2" class, that is given to one of its spans. Everything works well, except that I can't open the select2 programmatically. I tried: $('#id_search').select2('open') But it gives the error: "The select2('open') method was called on an element that is not using Select2.", because DAL doesn't pass the class "select2" to the rendered form field "id_search". Due to some peculiarities, I can't pass the class manually to the component. If I click on the field, it opens and works normally. I need some help in opening the select2 on page load. -

Assigning issue, unable to give or take roles in user admin , django
so basically what is happening is that i am trying to stop a user from acessing specific views, for example: admin and so on, unfortunately for some weird reason every time i create a user it receives every group role i created, even tho i didnt even write the code for it. I also cant take out a user from a group or put him in one, when i go inside a user infos. it is worth noting i am using, an abstract user model which may be the cause. This is how my user admin currently is, this is a new user by the way And this is how i think it should look like -
How to create separate form widgets for ModelMultipleChoiceField in Django
I have a ManyToMany relationship between two Django Models: Team and Member. A single Member can be part of multiple teams. I am able to successfully bind a Form class to a CreateView, and, using the standard ModelMultipleChoiceField,can successfully save the Form using the save_m2m method. However, the default widget for the field is not suitable for my user experience. Instead of using a picklist, I would like to create a separate select box for each number of selectable Members per team. For example, if the Team can have 7 Members, I would like to show 7 select boxes, rather than one pick list that a user selects 7 different objects from. I understand I may not get a complete answer, but would appreciate any pointers on if I should be looking into overriding the Field with a custom MultiWidget, or if using an inline formset might be a more appropriate route. Or, something else... -

Why does javascript create spurious images using ajax?

Circles not showing up in webpage when created via JavaScript (Django, Python)
I have made a page in my Django webapp that displays an image and allows the user to click on the image and should place a circle on top of the image where the user clicked. The following code is able to get the location of the mouse click on the image, and adds a tag to the html in the right place, but it won't actually show up on the page. If I hard code a circle into the html, it shows up just fine. It also seems like the mouse is on a different coordinate system than the SVG element... I have tried event.x, event.pageX, and event.clientX but noticed no difference. Even if I hard code the position of the circle, it won't show up on the click html: {% extends 'main/base.html' %} {% block head_content %} {% load static %} <script type="text/javascript" src="{% static 'js/click.js' %}"></script> {% endblock %} {% block content %} <div class="my-div"> <div> <h1>The Page!</h1> </div> <form enctype="multipart/form-data" method="POST" action="/mysite/nextpage/"> {% csrf_token %} <svg id="svg"> <image href="data:image/png;base64,{{ my_img }}"/> <!-- Placing a circle manually works just fine! --> <circle cx='50' cy='150' r='50' fill='red'/> </svg> <input type="submit" name="submit" class="submit-btn"></input> </form> </div> {% endblock %} Javascript: … -
get the name of the qs lookup instead of the value
I am trying to display the total number of tickets created in a day and have them show up as a dashboard feature . it only gives me the "0" for resolved and "p" for paused instead of the actual "Paused" or "Open".

How to use loop for requesting from html template in Django
From html template say "createlist" I want to add link which actually request server to get one more object of image form to the "createlist" page.

Cannot get Django to connect to MySQL within Dockerfile
I have been trying to get a Django project to connect to a MySQL database on my local computer using a Dockerfile. I would like to be able to do this so that I can use a container to host a website on AWS, so ideally I would like to use a Dockerfile only (not docker compose) as it makes installing it onto Elastic Beanstalk and Lightsail easy. I have created a repository on GitHub in the following location: https://github.com/MarkyMark1000/PYTHON_MySQL_Django_Docker I have tried all kinds of things such as using 'RUN apk update && apk add py3-mysqlclient' or trying to install python mysql connector, but I have no luck at present. If you could let me know what I need to do, I would be very grateful. Many thanks Mark -

Email automation for Amazon Orders - MWS API/SP API
I am trying to create a tool for sending automatic follow up ( review request, feedback request) for the Amazon order and I am using Amazon SES for the email service. I successfully connected marketplaces via login with Amazon and fetched user order, buyer email etc and sending emails to those buyer emails. SES shows they are delivered on the buyer email but I can't find them inside seller-buyer messages in amazon seller central. After playing around a bit I added my email as a verified sender on my own account then it sends the email and I can also see inside buyer-seller central. Now the problem is how can I verify my email as a verified email for other sellers who registered on my website via login with Amazon. Thanks in advance for the help. -
Django project is missing migrations, prodcution and development has different migrations
So I started working on a project that is right now on production but the preovious dev kinda made a mess with migrations (or maybe I am wrong), the migrations in developement and in production are not the same (he gitignored them) and I can not start working because there are missing migrations in development so the database is no fully migrated. Im thinking I can just delete all migrations in development, reset them but I don't think that is a good idea in production. What should I do? -
