Thank you for your hard work on this project! 🎉 While your code is well-structured and follows many best practices, there are a few critical issues that need to be addressed before we can approve the pull request. Specifically, the use of User instead of get_user_model() can impact the flexibility and maintainability of your code. Additionally, the redundant user.save() call and the missing migrations are important to fix to ensure the functionality and integrity of the application. Once these issues are resolved, your code will be in great shape! Keep up the great work, and I'm confident you'll nail it with the next iteration. 😊

The User model is being created here. If this is intended to replace the default Django user model, ensure that AUTH_USER_MODEL is set correctly in your settings. This is crucial for maintaining consistency across your application.

The UniqueConstraint on the Ticket model ensures that each combination of row, seat, and movie_session is unique. This is a good practice to prevent duplicate tickets for the same seat in a session.

The try-except block for User.DoesNotExist is redundant here since the outer try-except block already handles this exception. Consider removing the inner try-except block and directly handling the exception in the outer block.

Instead of printing an error message when a user does not exist, consider using logging or returning None to handle this case more gracefully.

Review Summary
Great job on your submission! 🎉 Your code demonstrates a solid understanding of Django's best practices, especially in areas like using transaction.atomic for atomic operations and extending AbstractUser for the custom User model. However, there are a few critical issues that need attention:
-
Custom User Model in Migrations: It's crucial to define your custom
Usermodel inmodels.pyand set it asAUTH_USER_MODELinsettings.pyrather than creating it directly in migrations. This ensures better integration with Django's authentication system. -
Use of
get_user_model(): Inservices/user.py, replaceUser.objects.create_user()andUser.objects.get()withget_user_model()to enhance flexibility and maintainability. -
Redundant
user.save()Call: Thecreate_userfunction contains an unnecessaryuser.save()call afterUser.objects.create_user(), which should be removed. -
Security Concern with
SECRET_KEY: Avoid hardcoding theSECRET_KEYinsettings.pyfor production. Use environment variables or a separate configuration file to manage sensitive information securely.
These adjustments will help you improve your code quality and adhere to best practices. Remember, addressing these issues will not only enhance your current project but also strengthen your skills for future endeavors. Keep up the great work, and continue learning from these experiences! 🚀

The creation of a User model directly in the migration is not recommended. Instead, you should define your custom user model in the models.py file and set it as the AUTH_USER_MODEL in your settings. This approach ensures that your user model is properly integrated with Django's authentication system.
