Django----JSON数据添加

#店主表
class Shop(models.Model):
    name = models.CharField(max_length=50)
    passwd = models.CharField(max_length=255)
    class Meta:
        db_table = 'shop'
#商品表
class Goods(models.Model):
    name = models.CharField(max_length=50)
    price = models.DecimalField(max_digits=7,decimal_places=2)
    image_url = models.CharField(max_length=255)
    shop = models.ForeignKey(Shop,on_delete=models.CASCADE,related_name='goods')
    class Meta:
        db_table = 'goods'
        
#如果要查看店主表下的商品直接方法就是序列化，格式添加
#序列化商品表
class GoodsModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = Goods
        fields = '__all__'

#序列化店主表
class ShopModelSerializer(serializers.ModelSerializer):
    #goods的变量名必须跟商品表里的related_name='goods'，goods一样，直接书写商品序列化many=True,就会生成json字符串，然后直接书写业务逻辑即可
    goods = GoodsModelSerializer(many=True)
    class Meta:
        model = Shop
        fields = '__all__'
