用于mongodb默认对象ID的串行器，在Django rest框架中有不同的字段名称？

Question

我想从＆＃39; id＆＃39;更改objectId名称到＆＃39; user_id＆＃39;在解析django请求时解析。我正在使用django-rest-framework-mongoengine

我的用户序列化程序看起来像这样

class UserSerializer(DocumentSerializer):

    user_id = serializers.Field(source='id')
    class Meta:
        model = User
        depth = 2
        fields = ('user_id','name','address')

Answer 1

您应该将字段定义为：

from rest_framework_mongoengine.serializers import DocumentSerializer
from rest_framework_mongoengine.fields import ObjectIdField
from my_app.documents import User

class UserSerializer(DocumentSerializer):

    user_id = ObjectIdField(source='id')
    class Meta:
        model = User
        depth = 2
        fields = ('user_id','name','address')

不同之处在于你应该使用django-rest-framework-mongoengine＆＃39; ObjectIdField。
