Bootstrap datatable queryParams & pagination

I don't understand why. I also have a little problem with my pagination: The pagination goes outside the card and my tags are correctly closed so I don't get why it goes sideway. Thank for your help. -

How to implement JWT access mechanism for a Django application (not django rest_framework)
I'm actually looking for a way to implement. I have a django project folder (only django, not django rest framework). All the views across all the apps in the project will be returning a JsonResponse parsed response. (Instead of rendering to a template) A basic view looks like this, with necessary imports from django.views.decorators.csrf import csrf_exempt from django.views.decorators.http import require_http_methods from django.http import JsonResponse @csrf_exempt @require_http_methods(['POST']) def sample_route(request): # validate request object, use them to query / process data # .. some more statements result = {"a": 1, "b": 2} return JsonResponse(result, status=200) I understand that this isn't a conventional practice like in a DRF project, but I would like to make such routes accessible by tokens (supposedly JWT). Can I get suggestions about how this would be possible - like with or without depending on djangorestframework library or any extensions or any other JWT associated libraries. Thanks -

Django admin - admin inheritance
When registering django admin, I inherited another admin, but I don't know why the model of list_display is changed. Let me explain the situation in detail with code. @admin.register(User) class UserAdmin(models.Model): list_display = [a.name for a in User._meta.concrete_fields] @admin.register(Sales) class SalesAdmin(UserAdmin): pass According to the code above, SalesAdmin Admin appears to inherit from UserAdmin. In this case, shouldn't list_display of User model appear in list_display? I don't understand why the list_display of Sales Model comes out. If I want to display the list_display of the Sales model while inheriting UserAdmin, shouldn't I have to redeclare the list_display as shown below? @admin.register(User) class UserAdmin(models.Model): list_display = [a.name for a in User._meta.concrete_fields] @admin.register(Sales) class SalesAdmin(UserAdmin): list_display = [a.name for a in Sales._meta.concrete_fields] I did not redeclare list_display, but I do not understand whether it is automatically output as the list_display of the changed model. If anyone knows, please explain. -

Querying within a list of dicts within a Django model JSONField
I'm trying to query an element within a list of dicts in a Django JSONField. I can find similar questions to mine but not one that covers what I'm trying to do. It seems like it should be simple and fairly common so I suspect I'm missing something simple. So. to expand slightly on the example in the Django docs Let's say I have a Dog model with a JSONField named data and it has some data like so: Dog.objects.create(name='Rufus', data = {"other_pets": [{"name", "Fishy"}, {"name": "Rover"}, {"name": "Dave"}]} ) There's a key named "other_pets" which is a list of dicts. I would like to write a query which returns any models which includes a dict with the key name=="Dave" I am able to directly do this if I refer to the element by the index, eg: Dog.objects.filter(data__other_pets__2="Dave") Would return me the row, but I need to reference the index of the list element, and both the position of the item I'm looking up, and the size of the list vary among models. I thought that maybe: Dog.objects.filter(data__other_pets__contains={"name":"Dave"}) Would work but this returns no elements. Is what I'm trying to do possible? As an aside, is it possible to add … -
