How can I implement advanced features in Django REST Framework?

You can implement advanced features like custom authentication, pagination, and filtering. What specific feature are you interested in?

I'm particularly interested in custom authentication methods.

For custom authentication, you can create a custom authentication class by extending BaseAuthentication. Would you like a code example?

Yes, please provide a code example for a custom token authentication.

Here's a simple example:

from rest_framework.authentication import BaseAuthentication
from rest_framework.exceptions import AuthenticationFailed

class CustomTokenAuthentication(BaseAuthentication):
    def authenticate(self, request):
        token = request.META.get('HTTP_AUTHORIZATION')
        if not token:
            return None
        # Validate the token and retrieve the user
        user = validate_token(token)
        if not user:
            raise AuthenticationFailed('Invalid token')
        return (user, None)
