Python self.assertContains失败；不能'；在响应中找不到*word*

我很难完全呈现

TopicsPage

的模板。假设它呈现

sub_heading.html

，它扩展了

listing.html

（两个模板位于同一个模板文件夹中）。测试通过了self.assertTemplateUsed（）断言

但是，在以下情况下会提出断言错误：

self.assertContains（响应“寻找更多？”）

AssertionError:False不正确：在响应中找不到“查找更多内容”

当模板已经在使用时，如何获取要呈现的

sub_heading.html

内容以通过测试？我特意将GET方法的实现设置为

pass

，以显示我是如何子类化视图的

test_views.py

class TestTopicsPage__002(TestCase):
    '''Verify that a topic and associated information is displayed
    on the main page once the topic is created'''

    @classmethod
    def setUpTestData(cls):
        user = User.objects.create_user("TestUser")
        python_tag = Tag.objects.create(name="Python")
        js_tag = Tag.objects.create(name="JavaScript")
        content = {
            'heading': "Test Title",
            'text': "Mock text content",
            'posted': datetime.datetime.now()
        }

        cls.topic = Topic(**content)
        cls.topic.author = user
        cls.topic.save()
        cls.topic.tags.add(python_tag, js_tag)

    def test_topics_main_page_rendered_topics(self):
        response = self.client.get(
            reverse("listing")
        )
        self.assertEqual(response.status_code, 200)
        self.assertTemplateUsed(response, "topics/sub_listing.html")
        self.assertContains(response, "Looking for more?")

由于listing.html扩展了index.html，因此它只能覆盖index.html中存在的块。以上内容必须放在{%block content%}内才能呈现。然后将呈现sub_listing.html对{%block page_branch%}的使用。

listing.html扩展index.html。index.html是否有块页面分支？我觉得listing.html的所有内容都应该在block content中，{%block page_branch%}块只在listing.html中。我试图创建两个从listing.html分支出来的模板。假设sub_listing.html和其他模板之间的listing.html内容相同。然而，这两个模板的内容在到达{%block page_branch%}时也是唯一的。我认为它永远不会到达{%block page_branch%}，因为它不是最高级别模板中的块，也不包含在最高级别模板中的块中。尝试将{%endblock content%}移动到最底部？这样就完成了任务。
