`07-django-models.md` 的 `models.ForeignKey` 現在需要on_delete #38

Open doomleika opened 6 years ago

doomleika commented 6 years ago 
class MenuItem(models.Model):

    store = models.ForeignKey('Store', related_name='menu_items')
    name = models.CharField(max_length=20)
    price = models.IntegerField()

    def __str__(self):
        return self.name

現在models.ForeignKey的 on_delete是必要參數
