Thank you for your hard work on this pull request! 😊 While your code is mostly well-structured and meets many of the task requirements, there are a few critical issues that need to be addressed before we can approve it:
-
Repetition of
save()Method: In thecreate_orderfunction, thesave()method is called twice. This can lead to inefficiencies and potential errors. Please refactor the code to ensuresave()is called only once. -
Use of Previously Created Functions: In the
update_userfunction, directly retrieving the user instead of using the existingget_userfunction affects readability and maintainability. Please update the code to use theget_userfunction. -
Exception Handling: Ensure that exceptions are handled when retrieving users by ID or username. This will prevent the application from crashing if a user is not found.
-
Return Type for
create_movie: The return type forcreate_movieis incorrectly specified. It should return aMovieinstance, not aQuerySet. -
Missing Migrations: Please confirm that the migration file is up-to-date with the current model changes to ensure tests pass.
Once these issues are addressed, your code will be in great shape! Keep up the good work, and feel free to reach out if you have any questions or need further assistance. 🚀

Ensure that the AUTH_USER_MODEL setting in your Django settings is correctly configured to use this custom User model. This is crucial for the ForeignKey relationship defined here.

The unique constraint 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 clean method in the Ticket model is correctly implemented to validate that the row and seat numbers are within the valid range for the associated cinema_hall. This ensures data integrity and prevents invalid ticket entries.

Calling self.full_clean() in the save method ensures that the clean method is executed before saving, which is a good practice to maintain data integrity.

Consider handling exceptions when retrieving the user by username. If the user does not exist, get() will raise a DoesNotExist exception, which should be caught and handled appropriately.

The AUTH_USER_MODEL setting is correctly configured to use the custom User model from the db app. This ensures that the custom user model is used throughout the project.

Great job on addressing most of the previous issues! 🎉 Your code is well-structured and adheres to Django's best practices in many areas. However, there are a few points that need your attention to enhance the code's functionality and maintainability:
-
Repetition of
save()Method: In thecreate_orderfunction, thesave()method is called twice. Refactor this to ensuresave()is called only once per object to avoid redundancy. -
Use of Previously Created Functions: Improve maintainability by using the
get_userfunction within theupdate_userfunction for consistency. -
Return Type for
get_orders: Update the return type annotation toQuerySet[Order]to accurately reflect the function's output. -
Exception Handling: Implement exception handling for scenarios where a
MovieSessionwith the given ID is not found to prevent runtime errors. -
Timezone Settings: Consider setting
USE_TZ = Trueto enable timezone-aware datetimes, which is a recommended practice for handling time data in Django applications.
These improvements will not only enhance the robustness of your code but also make it more maintainable and consistent. Keep up the great work, and continue learning from these experiences to refine your skills! 🚀

Implement exception handling to manage scenarios where the MovieSession with the given ID is not found. This will prevent potential runtime errors during deletion.

There was a problem hiding this comment.
The save() method is called twice in the create_order function: once after setting the created_at date and again implicitly when tickets are associated with the order. Consider refactoring to call save() only once after all modifications are complete to avoid redundancy.

The return type annotation for get_orders is incorrect. This function returns a QuerySet of Order objects, not a single Order. Consider updating the return type to QuerySet[Order].

Consider using the get_user function to retrieve the user instance in the update_user function. This will improve code maintainability and consistency by reusing existing functionality.
