Resolving the Superuser Login Issue in Django Rest Framework

When working with Django Rest Framework (DRF), encountering problems during user authentication can be frustrating, especially when you can't log in as a superuser. In this guide, we will walk through a common issue faced by developers and provide a tailored solution to get your superuser access back on track.

The Problem: Unable to Login as Superuser

Imagine you've created a superuser account in your Django application. Here are the credentials you've used:

Username: admin

Password: root

Even though you've created the superuser multiple times through the terminal and Django's ORM, the login attempt fails. This situation might look like the following code snippet you’ve tried:

Unfortunately, the response yields None, suggesting that Django cannot find or validate the superuser. This issue started occurring after integrating JWT tokens for authentication.

The Scenario:

Normal users authenticate without an issue and receive valid tokens.

However, attempts to log in using the superuser credentials fail.

Diagnosing the Issue

The underlying problem relates to how passwords are being handled in the custom User model. By default, Django's UserManager hashes passwords when creating a superuser. However, if you’ve overridden the save() method in your User model to also hash passwords, you may inadvertently cause a double-hashing scenario.

Example of Overridden save() Method:

This means whenever you use create_superuser, the password is hashed once by Django and then again by your custom logic, resulting in a hash conflict when trying to log in.

The Solution: Simplifying Password Handling

To fix this issue, you can do one of the following:

1. Avoid Overriding save():

Instead of rewriting the save method, use Django's built-in User methods that handle hashing automatically.

Create users with:

This approach hashes the password automatically during user creation, including superusers, without needing custom logic.

2. Maintain Custom Logic (If Needed):

If you still want to implement a custom save method, you must ensure that it's not causing double hashing for superuser accounts. You can check if a user is created as a superuser before going through the password hashing again.

Conclusion

In summary, the inability to log in as a superuser in Django Rest Framework often stems from double password hashing due to custom save methods. The recommended solution is to utilize Django's built-in methods for user creation, ensuring your passwords are hashed only once and correctly. By following these tips, you will not only resolve the current issue but also streamline your user management procedures.

With proper authentication in place, you can proceed confidently with your development, knowing that superuser access is within reach!
