Question

我的前端（Angular2）将JSON发布到我的Django Rest Framework后端。我很困惑我的序列化程序应该如何处理JSON并提取信息。我的ContactFormSerializer如何提取JSON data['userDetails']['email']？

# Posted data example:

{
    "sessionID": "1",
    "created": "2/12/2016",
    "completed": false,
    "payment": {
        ...
    },
    "userDetails": {
        "userID": 1,
        "email": "foo@gmail.com",
        "location": "US"
    }
}

class ContactUsView(APIView):

    def post(self, request):
        serializer =  ContactFormSerializer(data=request.data)

        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)


 class ContactFormSerializer(serializers.Serializer):

    def save(self):
        # How can I grab the user email address from the JSON?

        # send email to us

如果要为ContactFormSerializer编写自定义保存方法。也许它会有所帮助

def save(self,validated_data):
    user_details = validated_data.pop('userDetails')
    model = Model.objects.create(
        userID = user_details['userID'],
        email = user_details['email'],
        location = user_details['location']
    )
    model.save()
