Django restframework發送發佈數據從測試APIClient中斷

Question

request.data.get('answers_ids')返回str '2'而不是從APIClient數據發送的array ['1', '2']。但是，當我從休息框架web-gui發送數據的所有作品。

使用：

• Django的== 1.10.4
• djangorestframework == 3.5.3

tests.py：

class ApiCompletePoll(APITestCase): 
    def setUp(self): 
     self.user = User.objects.create(
      username='123', 
      password='123', 
      email='123@123.ru' 
     ) 
     self.client = APIClient() 
     self.client.credentials(
      HTTP_AUTHORIZATION='Token ' + self.user.auth_token.key 
     ) 

    def test_complete_poll(self): 
     data = {'poll_id': 1, 'answers_ids': [1, 2]}  # SENT DATA 
     self.client.post(reverse('complete-poll'), data) 
     self.assertTrue(
      CompletedPoll.objects.filter(
       user=self.user, poll__id=data['poll_id'] 
      ) 
     ) 

views.py：

@api_view(http_method_names=['post', ]) 
def update_or_create_user_answers(request): 
    user = request.user 
    poll_id = request.data.get('poll_id', 0) 
    answers_ids = request.data.get('answers_ids', []) 

    print(list(request.data.items()), request.data, answers_ids) # GETTING DATA 

輸出：

[('answers_ids', '2'), ('poll_id', '1')] 
<QueryDict: {'answers_ids': ['1', '2'], 'poll_id': ['1']}> 
2 

Answer 1

要檢索值的列表中，你需要使用.getlist()方法QueryDict傳遞的關鍵：

answers_ids = request.data.getlist('answers_ids', []) 

這應該輸出：['1', '2']
