当我运行 django 测试时，出现以下错误，这些错误超出了我的测试套件：

谁能解释一下，我做错了什么或者我应该如何设置才能通过这些测试？

【问题讨论】：

如果您发布产生错误的代码会有所帮助。
我真的不知道我可以发布什么 sn-p。这已经是一个有点大的项目了，我所有的测试（大约 90 个）都可以正常工作。我只是对来自 contrib.auth 的问题有疑问。

标签： django testing django-authentication django-contrib

【解决方案1】：

通过执行以下操作，我设法重现了您看到的测试结果：

MIDDLEWARE_CLASSES = (
    'django.middleware.cache.UpdateCacheMiddleware',
    .... <your middleware classes> ....
    'django.middleware.cache.FetchFromCacheMiddleware',
)

如果您有这些行，请尝试删除它们并重新运行单元测试。但是，我对此没有解决方案。

【讨论】：

我很确定这是一个错误。我提交了ticket #14105

【解决方案2】：

看起来您的上下文中没有可用的“用户”键，甚至根本没有上下文...

在您的 settings.py 中有以下内容吗？

TEMPLATE_CONTEXT_PROCESSORS = (
    "django.core.context_processors.auth",
    "django.core.context_processors.debug",
    "django.core.context_processors.media",
    "django.core.context_processors.request",

     etc ....
)

确实，您有 TEMPLATE_CONTEXT_PROCESSORS 吗？ IIRC django-admin.py startproject 实际上并没有将这些包含在默认 settings.py 中

希望有帮助

【讨论】：

我的设置中没有 TEMPLATE_CONTEXT_PROCESSOR，但是当我添加上面的行代码时它没有帮助。
TEMPLATE_CONTEXT_PROCESSOR 或 TEMPLATE_CONTEXT_PROCESSORS（注意“S”）
另外，您使用的是哪个版本的 Django？ osdir.com/ml/DjangoUsers/2009-05/msg00282.html 表示去年将修复推送到主干 --> code.djangoproject.com/changeset/10674

【解决方案3】：

如果你有 Python 2.6.5，你需要这个补丁：http://code.djangoproject.com/changeset/11821。

否则，您是否导入了 django.contrib.admin？ django.contrib.auth 的 tests 需要存在某些模板（如果它们不存在，您的代码不应该受到影响）才能工作，并且 django .contrib.admin 恰好提供了它们。

【讨论】：

我应该在哪里进行导入？在测试中？我确实有 Python 2.6.5，但我真的不想以这种方式修补我的 django，而宁愿等待我可以安装的正式版本。
你应该在你的 settings.py 中导入它（将它添加到 INSTALLED_APPS 列表中）。但是，对于 Python 2.6.5，如果没有补丁，它无论如何都会失败。如果你不想应用，我想你得等到 1.1.2 发布。
我已经安装了 1.1.2，但这没有帮助。所以我想这不是问题。
