'dict'對象沒有任何屬性'保存'POST不起作用

Question

我正在構建REST Web服務，GET方法似乎正在工作 但是當涉及到POST錯誤消息時總是顯示： '字典' 對象有 '保存'

models.py沒有屬性

from django.db import models 


class Users(models.Model): 
    Fullname = models.CharField(max_length=50) 
    Username = models.CharField(max_length=15) 
    Password = models.CharField(max_length=8) 
    Email = models.CharField(max_length=50, unique=True) 
    Type = models.CharField(max_length=5) 
    TwitterName = models.CharField(max_length=15, unique=True) 
    FacebookName = models.CharField(max_length=15, unique=True) 
    CreationDate = models.DateTimeField() 

serializer.py

class UserSerializer(serializers.ModelSerializer): 

    class Meta: 
     model = Users 
     fields = ('Fullname', 'Username', 'Email', 'Password', 'Type', 'TwitterName', 'FacebookName') 

views.py

@api_view(['GET', 'POST']) 
def users_list(request, format=None): 
    if request.method == 'GET': 
     users = Users.objects.all() 
     serializer = UserSerializer(users, many=True) 
     return Response(serializer.data) 

    elif request.method == 'POST': 
     serializer = UserSerializer(request.DATA, many=True) 
     if serializer.is_valid(): 
      serializer.save() 
      return Response(serializer.data, status=status.HTTP_201_CREATED) 
    return Response(serializer.data, status=status.HTTP_400_BAD_REQUEST) 

我使用PyCharm和Django的1.7

如果你要保存的POST數據，那麼你應該通過數據data關鍵字參數：

serializer = UserSerializer(data=request.DATA, many=True) 
     if serializer.is_valid(): 
      ... 

另外，我會建議你使用Class based views with Mixins，因爲這將使你的代碼更清晰aner和更短的：

from rest_framework import generics, mixins 

class UserList(mixins.ListModelMixin, 
       mixins.CreateModelMixin, 
       generics.GenericAPIView): 

    queryset = Users.objects.all() 
    serializer_class = UserSerializer 

    def get(self, request, *args, **kwargs): 
     return self.list(request, *args, **kwargs) 

    def post(self, request, *args, **kwargs): 
     return self.create(request, *args, **kwargs)
