How to separate user authentication in Django3 by the types of user?
is it possible to make an authentication option for users depending on their types in Django3? For instance, I have Customer and Seller which has one User model. When I am trying to sign as a Customer customer1@test.com with a sign-in/?next=/customer/ link it's signed as a user, if I will try to sign with the same Customer customer1@test.com into Seller sign-in/?next=/seller/ it will allow the same customer1@test.com user. How to split them and restrict users depending on sign URL link or maybe split the User model depending on the type of User(Seller, Customer). Thank you.

How to validate inlineformset_factory while validating the parent form?
I'm working on a Django project and I'm unable to find a way to validate an inlineformset_factory while validating the parent form. Its master/detail form approach SaleMSTForm is a parent model form from the SaleMST model and SaleDTLForm is a detail form from SaleDTL model. When I submit the form the parent form works fine and displays errors that it supposes to display while validation but the formset doesn't display any error and it got reset after the submission error. Also, I want to save both forms even if an error occurs the parent form shouldn't be saved. here's my code: models.py class SaleMST(models.Model): customer = models.ForeignKey(Customer, on_delete=models.RESTRICT) date = models.DateField() desc = models.CharField(max_length=200, blank=True) disc = models.DecimalField(max_digits=20, decimal_places=2, blank=True) created_by = models.CharField(max_length=20, null=True, blank=True) created_at = models.DateTimeField(auto_now_add=True) modified_by = models.CharField(max_length=20, null=True, blank=True) modified_at = models.DateTimeField(auto_now=True) def __str__(self): return self.desc class SaleDTL(models.Model): mst = models.ForeignKey(SaleMST, on_delete=models.RESTRICT) product = models.ForeignKey(Product, on_delete=models.RESTRICT) desc = models.CharField(max_length=200, blank=True) qty = models.IntegerField() def __str__(self): return self.desc forms.py class SaleMSTForm(forms.ModelForm): class Meta: model = SaleMST fields = ['customer', 'date', 'desc', 'disc'] widgets = { 'customer': forms.Select(attrs={ 'class': 'form-control' }), 'date': forms.DateInput(attrs={ 'class': 'form-control', 'type': 'date' }), 'desc': forms.TextInput(attrs={ 'class': 'form-control' }), 'disc': forms.TextInput(attrs={ 'class': 'form-control' }), … -
Cannot Authenticate Test Requests with Both User Token and API Key in Django Rest Framework
My project requires two authentication methods for some endpoints: A global API key using this app. A user authentication token using the default one provided by DRF All works fine when working with the API using Postman or an iOS app, but I couldn't make the authentication work in my tests. The user auth works fine, but the global key fails. This is how the HTTP headers look in Postman: X-Api-Key: KEY_VALUE Authorization: Token TOKEN_VALUE I tried to experiment with the code in the shell and authentication worked fine using the exact same code used in the test! Only in the tests it fails so I'm not really sure how to debug this further. This is a small sample of the project underneath hopefully it could help someone spot the issue. But if I missed posting something please let me know and I'll update it. app.views.py from rest_framework.views import APIView from rest_framework.response import Response from rest_framework import status from rest_framework.permissions import IsAuthenticated from rest_framework_api_key.permissions import HasAPIKey class MyView(APIView): permission_classes = [HasAPIKey, IsAuthenticated] def get(self, request, format=None): return Response(status=status.HTTP_200_OK) app.tests.py from rest_framework.test import (APITestCase, APIRequestFactory, force_authenticate) from rest_framework import status from accounts.models import User from .views import MyView class MyTests(APITestCase): def … -

Django Unit Testing : MultipleChoiceField dependent on objects created during setUp

The login session is not alive after setup in django unitest

Uncaught TypeError: t is null when plotting Polygon in Leaflet
I am trying to plot a polygon on a Leaflet map. I'm using Django with a postgis database (as bundled with Geodjango). I posted here last week, seeking advice on getting the polygon data out of the database and plotted on a map. I had 1 answer to this question which I think gets me very close to a resolution. The key, it seems, is to use Django's json_script tag. Having incorporated the answer's code into my app I get the error: Uncaught TypeError: t is not null.
