Question

这是 models.py：

的一部分

class Discount(models.Model):
    discount_id = models.AutoField(primary_key=True)
    discount_category = models.ManyToManyField(Category)
    discount_store = models.ManyToManyField(Store)
    ...

class Store(models.Model):
    store_id = models.AutoField(primary_key=True)
    store_company =models.ForeignKey('Company')
    store_city = models.ForeignKey('City', to_field='city_name')
    ....

这是我的 serializer.py：，

的一部分

class StoreSerializer(serializers.ModelSerializer):
class Meta:
    model = Store
    fields = ('store_location', 'store_city', 'store_name', 'store_address')


class DiscountSerializer(serializers.ModelSerializer):
    class Meta:
        model = Discount
        fields = ('discount_description', 'discount_start', 'discount_end', discount_title', 'discount_category', 'discount_store')

当我为折扣创建JSON时，我得到了这个JSON。

[{
    "discount_description": "Description here.",
    "discount_start": "2014-08-07T14:35:13Z",
    "discount_end": "2014-08-30T14:35:15Z",
    "discount_title": "Lorem İpsum",
    "discount_category": [
        3
    ],
    "discount_store": [
        1
    ]
}]

但我希望在＆＃34; discount_store＆＃34;中看到商店详情。我为此尝试了很多关系。但是我一直得到这个JSON。

您是否尝试将选项depth添加到Meta类？也许是这样的：

class DiscountSerializer(serializers.ModelSerializer):
    class Meta:
        model = Discount
        fields = ('discount_description', 'discount_start', 'discount_end', 'discount_title', 'discount_category', 'discount_store')
        depth = 1
