Question

我遇到中间件问题我发现了很多关于它的问题，但在我的情况下没有任何帮助。

我使用中间件来获取current_user以在我的模型中使用以在save方法中保存修改后的用户而不在视图中写入此内容。

中间件

from threading import local

_user = local()


class CurrentUserMiddleware(object):
    def process_request(self, request):
        _user.value = request.user


def get_current_user():
    return _user.value

此代码中存在错误，因为我收到的错误如下：

Traceback (most recent call last):
  File "C:\Program Files (x86)\Python35-32\Lib\wsgiref\handlers.py", line 137, in run
    self.result = application(self.environ, self.start_response)
  File "C:\Users\loc\dJangoEnvironment\lib\site-packages\django\contrib\staticfiles\handlers.py", line 63, in __call__
    return self.application(environ, start_response)

    self.load_middleware()

    mw_instance = mw_class()

我的中间件设置：

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.locale.LocaleMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.middleware.gzip.GZipMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'django.middleware.security.SecurityMiddleware',
    'reversion.middleware.RevisionMiddleware',
    'task.current_user',
)

你可以给我一些建议，哪里有错误或什么？我没有任何其他想法尝试，所以我希望你有一些。

您必须提供中间件类的完整路径。不是包含中间件的模块。

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.locale.LocaleMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.middleware.gzip.GZipMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'django.middleware.security.SecurityMiddleware',
    'reversion.middleware.RevisionMiddleware',
    'task.current_user.CurrentUserMiddleware',
)

请注意，上面有很多例子。
