Django 测试客户端响应包含空模板列表？

Question

根据 Django 测试文档，Django 客户端 Response 对象包含"template"，即:“用于呈现最终内容的模板实例列表，按照它们呈现的顺序排列。对于列表中的每个模板，如果模板是从文件加载的，则使用 template.name 获取模板的文件名。(该名称是一个字符串，例如“admin/index.html”。)”

但是，尽管我确信模板已渲染，但我得到的是空模板列表。

from django.test.client import Client
c = Client()
response = c.post('/signup/', {'email': 'a@b.com', 'password1': 'smith', 'password2': 'smith'}, follow=True)
print response.templates
# []

为什么模板是空的？我如何查看渲染的模板？

您是否在交互式 session 中尝试过您的代码？ Django documentation说:

Although * your code * [+] would work in the Python interactive interpreter, some of the test client's functionality, notably the template-related functionality, is only available while tests are running. The reason for this is that Django's test runner performs a bit of black magic in order to determine which template was loaded by a given view. This black magic (essentially a patching of Django's template system in memory) only happens during test running.

因此，如果您在测试运行中运行它，它应该可以工作。
