Django authentication with modelform

Question

I have two models

from django.contrib.auth.models import User class Vendor(models.MOdel): user = models.ForeignKey(User,related_name = 'vendor') ...................................................... ...................................................... class Customer(models.MOdel): user = models.ForeignKey(User,related_name = 'customer') ........................................................ ....................................................... 

what I want to do is enable the login for the provider and customer. The provider URL is “provider / login” and the client is “client / login”. While the provider submits its credentials, I want to check whether the user is a seller or not and is causing a verification error. I could not find a way to accomplish this with django. What I basically need is something like modelform for a user who checks that the user is a provider using queryset.But django auth has nothing like this.

Answer 1

You can use the Django custom model , add a type field, and use it as a factory source to load Vendor / Customer objects. This solution worked very well for me. Where to begin:

models.py

 from django.contrib.auth.models import AbstractUser TYPES = ( ('Vendor', 'Vendor'), ('Customer', 'Customer'), ) class MyUser(AbstractUser): type = models.CharField(max_length=10, choices=TYPES, default='Customer') 

This approach is very flexible and scales well if you need to add other types in the future. A small example of a forwarding approach:

 class Base(): def __init__(self, auth_user): self.user = auth_user def redirect_to(self): return "" class Vendor(Base): def redirect_to(self): return "/login/vendor" class Customer(Base): def redirect_to(self): return "/login/customer" 

Then, in the login view, you simply dynamically create a user object:

 auth_user = form.get_user() cls = globals()[auth_user.type] user = cls(auth_user) # This will return either Vendor or Customer object return HttpResponseRedirect(user.redirect_to()) 

You can easily create other types of users by simply adding a new class and applying the necessary methods without even touching the rest of the code.

The best strategy for me is to record two Authentication Backends, one of which allows authentication of the provider, and the other for the client.

AUTHENTICATION_BACKENDS is a settings constant that provides the root authorization code. here you can check the authentication documentation.

Declare your capabilities with a parameter parameter. When ordering, django will try to use all the backends until it is successful.
