How to Implement Multiple User Type Registration Using Django Rest Auth?

You can implement multiple user type registration using Django Rest Auth by extending the default user model and creating separate registration views for each user type.

1. Define User Types

First, define the different user types you want to support. For example:

Customer: A standard user who can purchase products.
Admin: A user with administrative privileges.
Vendor: A user who can sell products.

2. Extend User Model

Extend the default User model in Django to add a field for the user type:

from django.db import models
from django.contrib.auth.models import AbstractUser

class User(AbstractUser):
    USER_TYPE_CHOICES = (
        ('CUSTOMER', 'Customer'),
        ('ADMIN', 'Admin'),
        ('VENDOR', 'Vendor'),
    )
    user_type = models.CharField(max_length=10, choices=USER_TYPE_CHOICES, default='CUSTOMER')

3. Create Registration Views

Create separate registration views for each user type using Django Rest Framework. You can use the @api_view decorator to create the views:

from rest_framework.decorators import api_view
from rest_framework.response import Response

@api_view(['POST'])
def customer_registration(request):
    # ... (Implementation for customer registration)

@api_view(['POST'])
def admin_registration(request):
    # ... (Implementation for admin registration)

@api_view(['POST'])
def vendor_registration(request):
    # ... (Implementation for vendor registration)

4. Implement Registration Logic

In each registration view, you'll need to:

Validate the request data.
Create a new user instance.
Set the user type.
Save the user.
Send an email verification link (optional).

5. Configure Django Rest Auth

Use the REST_AUTH_REGISTER_SERIALIZERS setting to specify the serializers for each user type registration view:

REST_AUTH_REGISTER_SERIALIZERS = {
    'CUSTOMER': 'your_app.serializers.CustomerRegistrationSerializer',
    'ADMIN': 'your_app.serializers.AdminRegistrationSerializer',
    'VENDOR': 'your_app.serializers.VendorRegistrationSerializer',
}

6. Create Custom Serializers

Create custom serializers for each user type to handle specific fields and validation:

from rest_framework import serializers

class CustomerRegistrationSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ('username', 'email', 'password', 'user_type')
        extra_kwargs = {
            'user_type': {'required': True, 'default': 'CUSTOMER'},
        }

7. Update Frontend

Update your frontend to handle the different registration forms and redirect users to the appropriate views based on their chosen user type.

Conclusion

By extending the Django user model, creating separate registration views, and using custom serializers, you can implement multiple user type registration using Django Rest Auth. This approach allows you to create a more flexible and personalized user experience.
