Resolving the Call to undefined method App\Models\User::createToken() Error in Laravel

If you're new to Laravel and working on an application that involves user authentication, you might encounter an error that can be quite confusing. The error in question is: Call to undefined method App\Models\User::createToken(). This error can halt your progress, especially when you're eager to implement token-based authentication. In this guide, we'll break down this issue and provide you a clear solution to get your Laravel project back on track.

Understanding the Problem

The error arises when you try to call the createToken() method on a User model instance, and the Laravel framework cannot find this method. The createToken() method is integral when you are using Laravel Passport for API authentication, as it is responsible for generating an access token for the authenticated user.

Why Does This Happen?

Missing Trait in the User Model: The createToken() method resides within the HasApiTokens trait. If this trait is not included in your User model, Laravel won't recognize the method.

Authentication Setup Issues: Incorrect configurations in your authentication setup can also lead to this error, though in this case, the missing trait is the most likely culprit.

Solution: Adding the HasApiTokens Trait

To resolve this issue, you need to include the HasApiTokens trait in your User model. Here’s how to do it step by step:
