Django 的注销功能删除语言环境设置

Question

当我使用 Django 的注销功能注销经过身份验证的用户时，它会将区域设置切换为默认的 en_US。

from django.contrib.auth import logout

def someview(request):
    logout(request)
    return HttpResponseRedirect('/')

如何在退出后保留用户的语言环境？

Answer 1

我通过在自定义 View 中包装 django.contrib.auth.views.logout 并在注销后重置 session 语言解决了这个问题。有一些代码。

我有一个名为 login 的应用程序，其 urls.py 如下:

# myproject/login/urls.py
from django.conf.urls.defaults import patterns

urlpatterns = patterns('myproject.login.views',
    ...
    (r'^logout/$', 'logoutAction'),
    ...
)

所以现在 URL/logout/在 vi​​ews.py 中调用了一个名为 logoutAction 的 View 。在 logoutAction 中，旧的语言代码被临时存储，并在调用 Django 的 contrib.auth.views.logout 后插入回 session 。

# myproject/login/views.py
...
from django.contrib.auth.views import logout as auth_logout

def logoutAction(request):
    # Django auth logout erases all session data, including the user's
    # current language. So from the user's point of view, the change is
    # somewhat odd when he/she arrives to next page. Lets try to fix this.

    # Store the session language temporarily if the language data exists.
    # Its possible that it doesn't, for example if session middleware is
    # not used. Define language variable and reset to None so it can be
    # tested later even if session has not django_language.
    language = None
    if hasattr(request, 'session'):
        if 'django_language' in request.session:
            language = request.session['django_language']

    # Do logout. This erases session data, including the locale language and
    # returns HttpResponseRedirect to the login page. In this case the login
    # page is located at '/'
    response = auth_logout(request, next_page='/')

    # Preserve the session language by setting it again. The language might
    # be None and if so, do nothing special.
    if language:
        request.session['django_language'] = language

    # Now user is happy.
    return response
