Question

得到代码/

context['menu_shop'] = ShopMenu.objects.filter(shop=shop_id)

型号：

class ShopMenu(models.Model):
    name = models.CharField(max_length=255, verbose_name=u'Название раздела')
    shop = models.ForeignKey(Shop, verbose_name=u'Заведение',
                         related_name="menushop")

class ShopSubMenu(models.Model):

     name = models.CharField(max_length=255, verbose_name=u'Название подраздела')
    shopmenu = models.ForeignKey(ShopMenu, verbose_name=u'Надкаталог',
                             related_name="submenushop")
    dish = models.ManyToManyField(Dish, blank=True)

def __unicode__(self):
    return u'%s' % (self.name)

class Dish........

什么时候创建垂直分页符，但无法理解如何获得Dish限制那么我如何通过LIMIT FROM ShopMenu获得Dish？

\模板：

                            {% for menu in menu_shop %}
                          <h2 class="h1_title">{{ menu }}</h2>
              <div class="row row-catalog">
                          {% for submenu in menu.submenushop.all %}

                            {% for dish in submenu.dish.all %}

                                    choices=criterion_list,
                                    verbose_name=u'Критерий 2')

                               default=True, blank=True)
    sale = models.IntegerField(verbose_name=u'Скидка',
                           blank=True, null=True)
    is_active = models.BooleanField(verbose_name=u'Блюдо активно?',
                                default=True, blank=True)
    shop = models.ForeignKey(Shop, verbose_name=u'Заведение',
                         related_name="dishshop")

是的，是的。 Dish claass需要通过限制为每个子菜单获取它

从相关表中获取LIMIT
