Fixing JWT Token Issues with Custom User Models in Django

When working with Django's authentication system, particularly with JWT (JSON Web Tokens) and a custom user model, you may encounter a common problem: the lack of password hashing for users created via API views. This issue can prevent you from generating JWT tokens, leading to the frustrating error message: "No active account found with the given credentials." In this guide, we'll explain the problem in detail and provide a comprehensive solution to ensure your custom user model works seamlessly with JWT authentication.

Understanding the Problem

You have created a custom user model using Django and set up JWT authentication with Djoser. However, you noticed that while creating a superuser via the terminal works correctly, creating a user through an API view fails to hash the password. This results in JWT token creation issues because the authentication process can't recognize the user credentials.

Symptoms of the Problem

Creating a user via terminal works (passwords are hashed).

Creating a user via API results in a password that is not hashed.

Attempting to generate a JWT token for that user fails, returning the error: "No active account found with the given credentials."

Solution: Hashing Passwords in Custom Serializers

The main issue lies in the fact that the password is not being hashed when a user is created through the API. To fix this, you need to ensure that your serializer correctly handles password hashing during user creation. Here’s a step-by-step breakdown of the solution:

Step 1: Update Your User Serializer

To properly hash passwords when creating users through the API, you need to add a create method to your serializer. This method will handle user creation and ensure the password is set securely.

Here’s how you can implement the create method in your UserCreationSerializer:

Step 2: Ensure Proper Serializer Usage in Your Views

Make sure you're using the correct serializer in your UserView. When a POST request is made to create a new user, the UserCreationSerializer should be employed to validate and save the user instance:

Conclusion

By ensuring that password hashing is handled properly in your serializer, you can resolve the issue of JWT token creation with a custom user model in Django. This simple adjustment allows your API to create users with secured passwords, ultimately enabling successful JWT authentication.
