Django：如何将login_required装饰器应用于整个网站（不包括静态媒体）？ [英] Django: How can I apply the login_required decorator to my entire site (excluding static media)?

问题描述

示例提供了一个代码段对于应用程序级别视图，但是如果我的urls.py文件中包含许多不同的（和一些非应用程序）条目，包括模板呢？如何将这个login_required装饰器应用于每个装饰器？

The example provides a snippet for an application level view, but what if I have lots of different (and some non-application) entries in my "urls.py" file, including templates? How can I apply this login_required decorator to each of them?

(r'^foo/(?P<slug>[-\w]+)/$', 'bugs.views.bug_detail'),
(r'^$', 'django.views.generic.simple.direct_to_template', {'template':'homepage.html'}),

推荐答案

将其删除为code> middleware.py 文件在我的项目根目录中：

Dropped this into a middleware.py file in my project root:

from django.http import HttpResponseRedirect
from django.conf import settings
from re import compile

EXEMPT_URLS = [compile(settings.LOGIN_URL.lstrip('/'))]
if hasattr(settings, 'LOGIN_EXEMPT_URLS'):
    EXEMPT_URLS += [compile(expr) for expr in settings.LOGIN_EXEMPT_URLS]

class LoginRequiredMiddleware:
    """
    Middleware that requires a user to be authenticated to view any page other
    than LOGIN_URL. Exemptions to this requirement can optionally be specified
    in settings via a list of regular expressions in LOGIN_EXEMPT_URLS (which
    you can copy from your urls.py).

    Requires authentication middleware and template context processors to be
    loaded. You'll get an error if they aren't.
    """
    def process_request(self, request):
        assert hasattr(request, 'user'), "The Login Required middleware\
 requires authentication middleware to be installed. Edit your\
 MIDDLEWARE_CLASSES setting to insert\
 'django.contrib.auth.middlware.AuthenticationMiddleware'. If that doesn't\
 work, ensure your TEMPLATE_CONTEXT_PROCESSORS setting includes\
 'django.core.context_processors.auth'."
        if not request.user.is_authenticated():
            path = request.path_info.lstrip('/')
            if not any(m.match(path) for m in EXEMPT_URLS):
                return HttpResponseRedirect(settings.LOGIN_URL)

然后在设置中追加 projectname.middleware.LoginRequiredMiddleware 到我的MIDDLEWARE_CLASSES .py。

Then appended projectname.middleware.LoginRequiredMiddleware to my MIDDLEWARE_CLASSES in settings.py.
