'str' 对象没有属性 '_encode_json'

Question

我一直在用 RequestFactory 编写测试来测试我的一个视图，代码如下：

class ViewTestCase(TestCase):
@classmethod
def setUp(self):
    self.factory = RequestFactory
    self.user = User.objects.create_user(
        first_name='tester',
        username='test1', 
        password='123', 
        email='testuser@something.com'
        )

def test_room_creation(self):
    payload = {"titlePlanning": "Test1","styleCards": "Fibonnaci","deck": ["1","2","3"]}
    request = self.factory.post('/room', payload)
    request.user = self.user
    response = BeginRoom.as_view()(request)
    self.assertEqual(response.status_code, 200)

这是我需要发送才能使用的数据 POST:

class BeginRoom(APIView):
    permissions_classes = (IsAuthenticated,)
    def post(self, request, format=None):
    data= self.request.data
    user = request.user
    name = data['titlePlanning'].strip()
    styleCards = data['styleCards']
    cards = data['deck']

我的问题是，每当我运行我的测试时，我都会收到以下错误：

    data = self._encode_json({} if data is None else data, content_type)
 AttributeError: 'str' object has no attribute '_encode_json'

我该怎么办？我从这里迷路了，找不到任何相关的东西。感谢您的帮助！

Answer 1

而不是里面的这个 test_room_creation:

request = self.factory.post('/room', payload)

使用这个：

request = self.factory.post('/room', payload, content_type='application/json')

来自docs：

If you provide content_type as application/json, the data is serialized using json.dumps() if it’s a dict, list, or tuple.

'str' 对象没有属性 '_encode_json'
