Thank you for your hard work on this pull request! There are a few critical issues that need to be addressed before we can proceed:
-
Field Type for
show_time: Theshow_timefield in theMovieSessionmodel is currently set to useauto_now_add=True, which automatically sets the field to the current date and time upon creation. This is not suitable for a field that should be set manually. Please adjust this to allow manual setting. -
Foreign Key
on_deleteBehavior: The current setting ofon_delete=DO_NOTHINGfor foreign keys can lead to orphaned records. Consider usingCASCADEorSET_NULLto handle deletions more gracefully. -
Field Type for
rowsandseats_in_row: These fields are defined asIntegerField, which allows negative values. It would be more appropriate to usePositiveIntegerFieldto ensure only positive values are accepted. -
Related Name for ForeignKey: The
related_namefor thecinema_hallForeignKey in theMovieSessionmodel is set to"cinema_halls", which might be misleading. Consider using a more descriptive name like"movie_sessions".
Please address these issues to ensure the code fully meets the task requirements. Once these changes are made, your solution will be in great shape! Keep up the good work! 😊

The show_time field uses auto_now_add=True, which automatically sets the field to the current date and time when the object is created. This might not be suitable if you need to set the show time manually. Consider using auto_now=False and auto_now_add=False to allow manual setting.

The on_delete=django.db.models.deletion.DO_NOTHING setting for foreign keys means that no action is taken when the referenced object is deleted. This might lead to orphaned records in your database. Consider using CASCADE, SET_NULL, or another appropriate option to handle deletions more gracefully.

Changing rows from PositiveIntegerField to IntegerField allows negative values, which might not be appropriate for this field. Consider using PositiveIntegerField to ensure only positive values are accepted.

Consider using PositiveIntegerField for rows to ensure only positive values are accepted, as negative numbers do not make sense for this field.

The related_name 'cinema_halls' might be misleading as it suggests multiple halls. Consider using a more descriptive name like 'sessions' or 'movie_sessions' to better reflect the relationship.

The show_time parameter is expected to be a string, but MovieSession.show_time is a DateTimeField. Consider converting the string to a datetime object before assigning it to session_to_update.show_time.

The show_time field is set with auto_now_add=True, which automatically sets the field to the current date and time upon creation. This is not suitable for a field that should be set manually. Consider removing auto_now_add=True to allow manual setting.
