Thank you for your hard work on this project! 😊 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 the pull request:
-
Critical Issue in
models.py: TheTicketmodel'scleanmethod referencescount_rowsandcount_seats_in_rowattributes that do not exist in theCinemaHallmodel. This will cause errors during ticket validation and needs to be fixed to ensure the functionality of your application. -
Type Annotations: The task requires type annotations in class methods, which are currently missing in your viewsets and serializers. Adding these will improve code readability and maintainability.
-
Redundant
.all()Method: The use of the.all()method before.prefetch_related()and.select_related()in your viewsets is unnecessary and should be removed for optimal performance.
Once these issues are resolved, your code will be in great shape! Keep up the good work, and don't hesitate to reach out if you need any help. 🚀

Great job on your progress! 🎉 While your code is mostly well-structured and follows Django conventions, there are a few critical issues that need attention to ensure functionality and performance:
-
Critical Issue in
models.py: TheTicketmodel'scleanmethod references non-existent attributescount_rowsandcount_seats_in_rowin theCinemaHallmodel. This will cause errors during ticket validation and should be corrected. -
Type Annotations: The task requires type annotations for class methods. Adding these to your viewsets and serializers will enhance code readability and maintainability.
-
Redundant
.all()Method: The use of.all()before.prefetch_related()and.select_related()in your viewsets is redundant. Removing.all()will optimize performance. -
Minor Issue in
.gitignore: There's an extra space beforedb.sqlite3. Removing it will ensure consistency and avoid potential issues with ignoring the file.
These improvements are crucial for the functionality and performance of your code. Please address these issues in future revisions to enhance your learning experience. Keep up the good work and continue to learn from these challenges! 🚀

There is an extra space before db.sqlite3. It is recommended to remove this space to ensure consistency and avoid potential issues with ignoring the file.

The use of .all() before .prefetch_related() and .select_related() is redundant. You can directly use CinemaHall.objects.prefetch_related() or CinemaHall.objects.select_related() in the get_queryset method to optimize performance.
