Django setup url parameter for certain requests only
So I'm trying to setup my Django view such that when they POST to an endpoint they don't need an url parameters, but when they call GET they require it path('posts/', views.PostView.as_view(), name="post"), path('posts/<int:count>/', views.PostView.as_view(), name="post"), The issue with this is that it makes swagger messy and swagger with assume that url/posts/ you can POST and GET from, and url/posts// you can as well, but I only want to be able to POST to the first and GET from the 2nd. Is there a way to do this without creating separate view classes for them? Or is it better practice in this case to create separate view classes? -

My HTML and CSS causes this padding issue to happen in Django
I am not sure why when resizing my page this happens around the iPad media query level, and then gets fixed for smaller mobile devices like the iPhone once the toggle hamburger icon appears. It is broken until it goes below 768 x 1080 and above 908 x 1080. A lot of this was copy, and paste as I was trying to understand it, but this is stumping me. If anyone can help explain this issue in detail I would be very appreciative.

Should a background process be part of Django project?
I'm trying to build a web app which provide an interface to do some queries upon data extracted from another public API server. To complete the queries in real time, I would have to prefetch the data from the public API server. So I think it is reasonable to separate the app deal with query input(there is still some logic here, so only javascript wouldn't be enough) from the app which runs in background and builds the database which could possibly answer the query in real time. Then what comes to my mind is does this background app really have to be a part of Django project? It runs almost without interacting with any Django component. Except for the database which is also accessible by a Django app and some signals maybe(when to start/stop collecting data, but this could probably also decided internally). What would a be good design choice for my situation? -

Python Separate User Data - User Authentication/Access - Django
I've nearly built a full website using python and Django and now I need to build in separate user data. By this I mean I need to keep the same model and fields and pages but when User1 submits a form and it is displayed User2 who has logged in, the same form is there but User1's data will not be displayed for User2 to see and same for when User2 uploads data. I already have models made and I already have working signup and login. I've found a lot of information on restricting pages for curtain users and other things along those lines but that's not what I'm going for. This website will have a lot of users too so I can't really do something tricky with url's but I could be wrong. My models are very big so I would prefer a solution that automatically does something for all of them but at this point I'll take any solution and any help. Thanks! -

Why am I getting 'module not found' on my project when trying to deploy django with apache and bitnami?
I realize this question has been asked, I've tried the other solutions but can't get the configuration right. I'm using the django instance on aws lightsail.

Django Paypal: How To Pass User ID With Webhooks Or In Subscription
I am trying to pass the user id with the webhook or the subscription so that i can know which user has subscribed.

Is there a better way to do this? i have seen a few hack ways of doing it but they don't seem like the best way. I am trying to look for ways so i think i can maybe pass the subscriber id by javascript on approve of the subscription and then use that to identify the user but i would rather not use ways that can be manipulated by javascript. -

Self-submitting CreateView form
As a newcomer to Django, I'm struggling to achieve my ultimate aim of submitting a form to the same page on which it's defined and displaying values entered in the form within text elements of an SVG diagram, displayed below the form. Thus far, I've managed to create a form using a CreateView and can submit the contents of that form to a separate view which displays the entered values in SVG format... models.py class Diagram(models.Model): val1 = models.FloatField(null=True, blank=True, default=None) val2 = models.FloatField(null=True, blank=True, default=None) def get_absolute_url(self): return reverse('diagram-results', kwargs={'diagram_id': self.pk}) forms.py class DiagramForm(ModelForm): class Meta: model = Diagram fields = ['val1', 'val2'] views.py def show(request, diagram_id): try: diagram = Diagram.objects.get(pk=diagram_id) except Diagram.DoesNotExist: raise Http404("Diagram does not exist") return render(request, 'calc_app/diagram.svg', {'diagram': diagram}) class DiagramCreateView(CreateView): model = Diagram form_class = DiagramForm urls.py urlpatterns = [ path('diagram/add/', DiagramCreateView.as_view(), name='diagram-add'), path('diagram/<int:diagram_id>/', views.show, name='diagram-results'), ] diagram_form.html {% extends "calc_app/base_generic.html" %} {% block content %} <form action="." method="post"> {% csrf_token %} <table> {{ form.as_table }} </table> <input type="submit" value="Submit"> </form> {% endblock %} diagram.svg <svg width="800" height="600" xmlns="http://www.w3.org/2000/svg"> <text id="val1" stroke="#ddd" y="50.0" x="50.0">{{ diagram.val1 }}</text> <text id="val2" stroke="#ddd" y="50.0" x="50.0">{{ diagram.val2 }}</text> </svg> I'd like to take this one step further and submit …
