如何测试为 CBV ListView 生成的上下文中是否存在“object_list”

Question

我正在尝试编写一个测试，测试在基于类的视图ListView 传递的上下文中是否存在object_list。

目前我有代码：

views.py

    class BlogView(ListView):
        model = Post
        template_name = 'core/blog.html'

model.py:

    class Post(models.Model):
        title = models.CharField(max_length=500)
        content = models.TextField()

tests.py

    class BlogListViewTests(TestCase):

        def setUp(self):
            self.resp = self.client.get('/blog/')

        def test_has_a_post_list(self):
            self.assertContains(u'post_list', self.resp.context)

当我运行测试时出现以下错误：

    Traceback (most recent call last):
      File "/home/breno/projects/blog/core/tests.py", line 36, in test_has_a_post_list
          self.assertContains(self.resp.context, 'post_list')
      File "/home/breno/.virtualenvs/blog/local/lib/python2.7/site-packages/django/test/testcases.py", line 325, in assertContains
          self.assertEqual(response.status_code, status_code,
     AttributeError: 'ContextList' object has no attribute 'status_code'

打印self.resp.context 我看到一个带有u'post_list' 键的Tube：

[[{'False': False, 'None': None, 'True': True}, {u'paginator': None, u'post_list': [], u'object_list': [],...,]]

我的测试出了什么问题？我怎样才能做这个测试？类型

class BlogListViewTests(TestCase):

    def setUp(self):
        self.resp = self.client.get('/blog/')

    def test_has_a_post_list(self):
        self.assertTrue('post_list' in self.resp.context)
