Django Rest Framework - Authentication credentials were not provide even with auth header, rest_framework.authtoken
So best I can tell this happened out of nowehere, I just deployed this API and it was working two days ago now that I've come back to it it's not working. I've regenerated fresh tokens, Tried with Curl vs postman and both fail, set cloudflare to dev mode and double checked their documentation (which states headers are pass thru), Verified TokenAuthentication was specified in my auth classes as well as double-checked my AuthenticatedUser default auth level. deleted and regenerated the database to create a fresh superuser I can get a token I just can't do anything past that. Any advice or guidance would be MUCH appreciated.

How to refer to all child objects with existing queries in self-referencing foreign key?
I have a model that represents an owner. There is a foreign key on this model to itself to represent a parent entity. There is another model called asset with a foreign key to owner. The purpose of the parent foreign key is to emulate a corporate structure, such that a parent “owns” an Asset whose foreign key is itself or a subsidiary: Class Owner(models.Model): parent = models.ForeignKey( “self”, ) Class Asset(models.Model): owner = models.ForeignKey( Owner, ) Is there a way return all assets owned by a parent and all of its subsidiaries by simply referencing the parent (eg Asset.object.filter(owner=parent))? I know I can create a method to return a queryset of all subsidiaries of a parent, and then filter to all assets in that owner queryset, but I am hoping to avoid a large refactor given the existing code base doesn’t have the concept of a parent owner. My first thought is a custom manager, but I don’t think that will change the behavior of existing queries that are all off the default manager. Can I overload filter on this model? If I need to rethink design that is fine, but I think this approach is cleaner and captures … -
Django REST Framework missing imports with Docker
So, recently I've started creating project using Docker for the first time so my knowledge is not very great. When I'm creating venv using python3 -m venv venv, and installing Rest Framework, everything works fine and I'm not having any problems at all. But in my project with Docker, I have no idea why but PyLance detects missing imports with Django and Django REST. It is really annoying, also when I'm making imports from Django, it makes suggestions: But it won't suggest anything when making imports from REST Does anyone know how to fix this issue? I've tried: Opening VSC in different directories Rebuliding Docker image Everything works fine, my requirements file contains REST Framework therefore it works fine. It is all about theese non-sense missing modules. -

How do I populate my form with the data sent by a user after a GET request in Django?
def index(request): if len(request.GET) == 0: form = FlightSearchForm() else: arr = request.GET.get('arrival_airport') dep = request.GET.get('departure_airport') form = FlightSearchForm({'departure_airport': dep,'arrival_airport': arr}) return render(request, 'app1/index.html', {'form': form}) What I want to do is create a form that would allow users to search for a flight, so I need them to use GET request. The problem is I don't know how to make their search appear in the fields after they go to their specific url (with all the details they searched for). It worked with a POST request in the past, but obviously I can't use it in this case. class FlightSearchForm(forms.Form): def __init__(self, *args, **kwargs): self.departure_airport = kwargs.pop('departure_airport') self.arrival_airport = kwargs.pop('arrival_airport') super.__init__(*args, **kwargs) departure_airport = forms.CharField(max_length=100) arrival_airport = forms.CharField(max_length=100) I tried something like that but it didn't help. Now it shouts that there is a keyerror, which doesn't exist. What can I do about this? -
Django ORM with PostgreSQL return wrong data using icontains
My model is class Seller(models.Model): supplierId = models.IntegerField('Supplier ID', primary_key=True) supplierName = models.CharField('Поставщик', max_length=255, null=True, blank=True) inn = models.CharField('ИНН', max_length=255, null=True, blank=True) ogrn = models.CharField('ОГРН', max_length=255, null=True, blank=True) legalAddress = models.CharField('Юридический адрес', max_length=512, null=True, blank=True) I have 2 records with the same supplierName='Смирнова Ольга Александровна'. sellers = Seller.objects.filter(supplierName__icontains='Смирнова Ольга Александровна') print(sellers.count()) # return 1 sellers = Seller.objects.filter(supplierName__contains='Смирнова Ольга Александровна') print(sellers.count()) # return 2 sellers = Seller.objects.filter(supplierName='Смирнова Ольга Александровна') print(sellers.count()) # return 2 I also try to use supplierName__search, but it returns not normal data too. icontains return wrong data not only in this example. What can i do with it? I need this for correct search on my site.
