Question

我想在django admin中编辑与碟子面板上的菜相关的美食。我正在尝试使用 InlineModelAdmin 。问题是我可以编辑DishCuisinesMap对象，但不能编辑菜肴对象。这是屏幕截图：

这是我的models.py：

class Cuisines(models.Model):
    cuisine_id = models.IntegerField(primary_key=True)
    cuisine_mtom = models.ManyToManyField('DishInfo', through='DishCuisinesMap')
    name = models.TextField()
    cuisine_sf_name = models.TextField() 
    type = models.IntegerField()
    insert_time = models.DateTimeField()
    update_time = models.DateTimeField()

    class Meta:
        managed = False
        db_table = 'cuisines'

class DishCuisinesMap(models.Model):
    dish = models.ForeignKey('DishInfo', on_delete=models.PROTECT,
                             related_name='dcm_dish')
    cuisine = models.ForeignKey(Cuisines, on_delete=models.PROTECT,
                                related_name='dcm_cuisine')
    insert_time = models.DateTimeField()
    update_time = models.DateTimeField()

    class Meta:
        managed = False
        db_table = 'dish_cuisines_map'
        unique_together = (('dish', 'cuisine'),)


class DishInfo(models.Model):
    dish_id = models.BigIntegerField(primary_key=True)
    bid = models.ForeignKey(Brands, on_delete=models.PROTECT, db_column='bid',
                            related_name='dinfo_brand')
    name = models.TextField()
    is_live = models.IntegerField()
    veg_nonveg_ind = models.SmallIntegerField(blank=True, null=True)
    sf_name = models.TextField()
    descr = models.TextField(blank=True, null=True)
    expert_tag = models.TextField(blank=True, null=True)
    special_desc = models.TextField(blank=True, null=True)
    reco_percent = models.IntegerField(blank=True, null=True)
    one_liner = models.TextField(blank=True, null=True)
    nutrition = JSONField() 
    insert_time = models.DateTimeField()
    update_time = models.DateTimeField()
    images = ArrayField(models.TextField()) 

    class Meta:
        managed = False
        db_table = 'dish_info'
        unique_together = (('bid', 'name'), ('bid', 'sf_name'),)

    def __unicode__(self):
        brand_name = self.bid.name
        return self.name

这是我的admin.py：

class CityDishFilter(admin.SimpleListFilter):
    title = ('city name')
    parameter_name = 'city_id'

            list_of_cities.append(
                    (str(city.city_id), city.name)
                )
        return list_of_cities

    def queryset(self, request, queryset):

            dopm_query = DishOutletPlatMapping.objects.filter(plot__in

django docs here表示可以从Person或Group详细信息页面编辑成员资格对象，但是从人员详细信息页面编辑组的方法是什么？在我的情况下，我需要一种方法来编辑菜肴页面上的美食，我是django的新手。非常感谢任何帮助。
