如何访问DRF服务器端的请求主体模型字段？

Question

在android客户端，我向带有ContactRequest主体的服务器端点发出请求：

public class ContactRequest {

    @SerializedName("senderId")
    @Expose
    private int senderId;

    @SerializedName("receiverId")
    @Expose
    private int receiverId;

    public ContactRequest(int senderId, int receiverId) {
        this.senderId = senderId;
        this.receiverId = receiverId;
    }
}

使用改造，我将此对象作为请求主体传递：

@POST("friendship/create-friend-request/")
Call<Void> sendRequest(@Body ContactRequest contactRequest);

在服务器端，然后将此端点​​映射到CreateFriendRequestView ：

class CreateFriendRequestView(views.APIView):

    def post(self, request, *args, **kwargs):
        sender = User.objects.get(pk=request.senderId)
        receiver = User.objects.get(pk=request.receiverId)
        Friend.objects.add_friend(sender, receiver)
        return Response({'status': 'Request sent'}, status=201)

但是，当对此端点发出请求并调用该视图时，发生内部服务器错误，状态码为500。

AttributeError：“请求”对象没有属性“ senderId”

如何在Django senderId Framework客户端上引用字段senderId和receiverId ？

Answer 1

请求数据在请求对象的data字段中。

结帐http://www.django-rest-framework.org/api-guide/requests/#data

您必须使用：

sender = User.objects.get(pk=request.data.get('senderId'))

request.data是一个python字典。
