Thank you for your hard work on this project! 🌟 There are a few critical issues that need to be addressed before we can approve the pull request. Specifically, the related_name for the cinema_hall field in the MovieSession model is misleading and should be changed to something more descriptive like 'sessions'. Additionally, the get_movie_by_id and get_movie_session_by_id functions should handle potential DoesNotExist exceptions more gracefully, perhaps by using get_object_or_404 if these functions are used in views. Once these issues are resolved, your code will be in great shape! Keep up the great work! 💪

The related_name for the cinema_hall field in the MovieSession model is set to 'cinema_halls'. This might be misleading because it suggests a reverse relation from CinemaHall to MovieSession instances. Consider changing it to something more descriptive like 'sessions' to better reflect the relationship.

The get_movie_by_id function uses Movie.objects.get(id=movie_id), which will raise a DoesNotExist exception if no Movie with the given ID exists. Consider using get_object_or_404 from Django shortcuts if this function is used in a view, or handle the exception appropriately if used elsewhere.

Great work on setting up the models and migrations! 🎉 Your implementation is mostly aligned with Django's best practices, and the structure is well-organized. However, there are a few areas to improve:
-
Exception Handling: The
get_movie_by_idandget_movie_session_by_idfunctions currently lack exception handling forDoesNotExisterrors. It's recommended to useget_object_or_404if these functions are used in views, or handle the exceptions within the functions to ensure robustness. -
related_nameforcinema_hall: Therelated_namefor thecinema_hallfield in theMovieSessionmodel was initially misleading but has been updated to'movie_sessions', which is now appropriate and descriptive.

The cinema_hall field in the MovieSession model is missing a related_name. Consider adding related_name='sessions' to provide a descriptive reverse relation name.

The get_movie_by_id function should handle the DoesNotExist exception to avoid potential errors if the movie ID is not found. Consider using get_object_or_404 if this function is used in views, or handle the exception within the function.
