的Python，Django的，教程，測試詳細信息視圖，錯誤

Question

我通過Django的教程製作方式，並在教程5>「測試詳細信息視圖」

已經跌進錯誤在我的部分。當我運行：

python manage.py test polls

在終端

，我迎接此消息：

Creating test database for alias 'default'... 
.F.......

這是對「噸的代碼我有tests.py內相用過去的問題來看詳細視圖'（它是函數的後者）。

class QuestionIndexDetailTests(TestCase): 
    def test_detail_view_with_a_future_question(self): 
     """

     return a 404 not found. 
     """ 
     future_question = create_question(question_text='Future question.', 
              days=5) 
     response = self.client.get(reverse('polls:detail', 
            args=(future_question.id,))) 
     self.assertEqual(response.status_code, 404) 

    def test_detail_view_with_a_past_question(self): 
     """

我是新來的社區＃1，所以我很抱歉，如果這個問題的格式和phraising是不正確，不完整或不恰當的，但是從這個問題提前任何幫助，將不勝感激。

你要檢查 '過去的問題。'在response.content中，而不是response。將test_detail_view_with_a_past_question的最後一行更改爲：

self.assertContains(response.content, past_question.question_text, 
         status_code=200)
