How to create objects while creating another object?

Question

Django

Hello, do you have models?

class Day(models.Model):
    date = models.DateField()


class ReservedTable(models.Model):
    is_reserved = models.BooleanField()
    table = models.ForeignKey(Table, on_delete=models.CASCADE)
    day = models.ForeignKey(Day, on_delete=models.CASCADE)

how is it possible, when creating a Day, to run through all Tables, create a ReservedTable and associate it with the same Day?

Answer 1

post_save signal on Day.
And there, already inside, go over the table and assign the day to the ReservedTable, which will fly to you in instance ...
