Passing instance of a model to another model

Using Django
21

I tried this

def save(self, *args, **kwargs):
        
        super(Movie, self).save(*args, **kwargs)
        self._create_seats()

but throws different error: FOREIGN KEY constraint failed

22

The error would have more detail - which Foreign Key constraint failed?

23

Probably the movie field

24

I already solve the problem by setting the db_constraints to False. Thank you! <3

movie = models.ForeignKey(Movie, on_delete=models.CASCADE, db_constraint=False)
