    cost = models.IntegerField(default=0) 
    slot = models.Model(OrderSlot) 
    order_date = models.DateTimeField(default=datetime.now) 

    def __str__(self): 
     return self.user.name

Answer 1

olduğunu

Sorun, User modeliyle olan ilişkiyi tanımlama biçiminizdir:

Bunu yerleştirilen bir kullanıcıya bir bağlantı var Order istiyorsanız

class Order(models.Model): 
    itemDict = models.CharField(max_length=200,blank=True) 
    user = models.Model(User) # <- HERE 

, ForeignKey field kullanın: "yuvası" modeli de

user = models.ForeignKey(User) 

^{kontrol. Aynı sorun.}
