私はモデル製品を持っていて、製品バリエーションのサブモデルバリエーションを持っています。今、私は、商品のショップモデルトップを追加しようとしています。ショップを作成したショップオーナーがアップロードした商品を表示したいと考えています。しかし、私はエラーが発生しています。以下は、私のコードです：私は店を追加しようとしたとき、私は取得していますモデルのDjango ORMが機能しない

class Product(models.Model): 
    title = models.CharField(max_length=120) 
    description = models.TextField(blank=True, null=True) 
    price = models.DecimalField(decimal_places=2, max_digits=20) 
    active = models.BooleanField(default=True) 
    categories = models.ManyToManyField('Category', blank=True) 
    default = models.ForeignKey('Category', related_name='default_category', null=True, blank=True) 
    hits = models.ManyToManyField(HitCount, blank=True) 
    hitcounts = GenericRelation(HitCount, content_type_field='content_type', object_id_field='object_pk',) 


    objects = ProductManager() 

    class Meta: 
     ordering = ["-title"] 

class Variation(models.Model): 
    product = models.ForeignKey(Product) 
    title = models.CharField(max_length=120) 
    price = models.DecimalField(decimal_places=2, max_digits=20) 
    sale_price = models.DecimalField(decimal_places=2, max_digits=20, null=True, blank=True) 
    active = models.BooleanField(default=True) 
    inventory = models.IntegerField(null=True, blank=True) #refer none == unlimited amount 

    def __unicode__(self): 
     return self.title 

class Shop(models.Model): 
    user = models.ForeignKey(settings.AUTH_USER_MODEL, null=False, blank=False) 
    products = models.ManyToManyField(Product) 
    name = models.CharField(max_length=120) 
    image = models.ImageField(upload_to=image_upload_to_shop, null=True) 
    location = models.CharField(max_length=120) 

    def __unicode__(self): 
     return self.name

エラーはクリアされ、中間テーブルは存在しません。 makemigrationsを実行して移行しましたか？ –
