django 模型序列化器合并

Question

使用django2.0.2 ptyhon3.4

MySerializer.py
class post(serializers.ModelSerializer)
    class Meta:
        model = post
        fields = ("postuid","useruid","content")

class reply(serializers.ModelSerializer)
    class Meta:
        model = reply
        fields = ("replyuid","postuid","useruid","content")

class postview(serializers.ModelSerializer)
    reply = reply()
    post  = post()
    fields = ('reply','post')???

我想要这样的表格

{"postview":{"post":{postfield},"reply":[{replyfield}]}

怎么做

postview 不是模型序列化器？

Answer 1

您可以改用serializers.Serializer 类：

class postview(serializers.Serializer):
    reply = reply(many=True)
    post  = post()

注意Serializer 基类您不需要Meta 选项。只需添加尽可能多的字段作为序列化程序的属性。

您可以使用many=True 属性来指定reply 包含对象列表。
