Question

这与问题Assymetric nature of GET and POST in a Django REST framework Serializer有关。我把它作为一个新问题，而不是在该主题中提出更多问题，而不是SO指南

我正在为User模型编写一个Viewset和一个ModelSerializer来提供一个/ user端点

GET - 以标准DRF方式返回所有用户的列表和信息

POST - 我希望客户端发布的是facebook access_token（因此将所有其他字段作为read_only放在序列化程序中.ViewSet中的pre_save（）连线使用此访问令牌并使用{{ 1}}从facebook api中提取数据（使用访问令牌）并自动创建一个包含该信息的新用户。由于这个新的 django-facebook 是自动创建的，我想抑制正常的DRF在POST期间流动而不是通过DRF创建另一个用户。我该怎么做？

views.py

user

serializers.py

from open_facebook import OpenFacebook
from django_facebook.api import FacebookUserConverter
from django_facebook.connect import connect_user

class UserViewSet(viewsets.ModelViewSet):

    queryset = models.User.objects.all()

    serializer_class = UserSerializer

    def pre_save(self, obj):


        access_token = obj.access_token
        facebook = OpenFacebook(access_token)
        conv = FacebookUserConverter(facebook)

        action, user = connect_user(self.request, access_token)
        # this creates an entire new row, just as required, in the variable "user", so all I want to do is suppress any other row creation in the standard POST method. connect_user fills in data like first_name, last_name, etc from facebook already, and that is exactly what I need to do.


        conv.get_and_store_friends(user)

        obj = user
        user.delete()
        # I am trying to do that by copying user to obj and deleting user, but at the end of it i 

        print obj.username

使用ModelViewSet的create（）函数工作，而不是pre_save - 来禁止保存对象

抑制POST中的对象SAVE - Django Rest Framework
