AssertionError：移动到基于函数的视图时，False不成立

标签： python django django-models tdd django-views

我正在使用测试驱动开发方法在Django 1.6中创建一个基本博客。

我关注了this tutorial，但我想改用基于函数的视图，因为我刚开始使用Django。

我在测试中遇到此错误，并且我的index.html模板上没有显示任何内容：

self.assertTrue(post.title in response.content)
AssertionError: False is not true

我评论它是否只是那一行，但self.assertTrue def test_index(self): class PostViewTest(LiveServerTestCase):中的所有<html> <head> <title>My Django Blog</title> </head> <body> {% for post in object_list %} <h1>{{ post.title }}</h1> <h3>{{ post.pub_date }}</h3> {{ post.text }} {% endfor %} </body> </html> 测试都发生了这种情况。

在模板中，帖子列表称为object_list，而在您的视图中，您将其作为post传递。两者需要匹配。

如果您将视图更改为以下内容，我认为应解决此问题：

def index(request):
        # get the blog posts that are published
        posts = Post.objects.all
        # now return the rendered template
        return render(request, 'blogengine/index.html', {'object_list': posts})

此外，您的设置中是否将Debug设置为True？这将启用堆栈跟踪，使这更容易调试，如果找不到模板，它会提出一条消息来确认这一点。

很高兴你喜欢我的教程！

您是否在settings.py中设置了TEMPLATE_DIRS？它没有找到你的模板。
