Django語言沒有切換模板

全部。我有一些問題與語言切換的非常簡單的應用：Django語言沒有切換模板

settings.py

INSTALLED_APPS = (
    'django.contrib.admin', 
    'django.contrib.auth', 
    'django.contrib.contenttypes', 
    'django.contrib.sessions', 
    'django.contrib.staticfiles', 
) 

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware', 
    'django.middleware.locale.LocaleMiddleware', 
    'django.middleware.common.CommonMiddleware', 
    'django.middleware.csrf.CsrfViewMiddleware', 
    'django.contrib.auth.middleware.AuthenticationMiddleware', 
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware', 
) 

ROOT_URLCONF = 'lr.urls' 

TEMPLATES = [ 
    { 
     'BACKEND': 'django.template.backends.django.DjangoTemplates', 
     'DIRS': [ 
      os.path.join(BASE_DIR, 'templates'), 
     ], 
     'APP_DIRS': True, 
     'OPTIONS': { 
      'context_processors': [ 
       'django.template.context_processors.i18n', 
       'django.template.context_processors.debug', 
       'django.template.context_processors.request', 
       'django.contrib.auth.context_processors.auth', 
      ], 
     }, 
    }, 
]

urls.py

urlpatterns = [ 
    url(r'^$', home, name='home'), 
    url(r'^auth/(?P<cmd>.*)$', auth, name='auth'), 
    url(r'^i18n/(?P<lang>.*)$', i18n, name='i18n'), 
    url(r'^admin/', include(admin.site.urls)), 
]

views.py

class HomePageView(TemplateView): 
    """ 
    Template view for Home page 
    """ 
    template_name = 'home.html' 


def home(request): 
    """ 
    Site title page 
    """ 
    return HomePageView.as_view()(request) 


def i18n(request, **kwargs): 
    """ 
    Change locale processing 
    """ 
    from django.utils.translation import check_for_language 

    if 'lang' in kwargs: 
     lang = kwargs['lang'] 

     if lang and check_for_language(lang): 
      if hasattr(request, 'session'): 
       request.session[LANGUAGE_COOKIE_NAME] = lang 

    if request.method == 'POST' \ 
      and 'redirect' in request.POST: 
     # Place hidden input, named 'redirect' in login form in html template 
     # for making redirect to the same page after login/logout 
     return HttpResponseRedirect(request.POST['redirect']) 

    return HttpResponseRedirect('/')

頁模板空，它只是標題，登錄表單和ru/eng切換表單（只有三個單詞用於翻譯）。

不知何故，模板中的語言代碼（get_current_language）總是'en'，除非我將'django.middleware.locale.LocaleMiddleware'放在MIDDLEWARE_CLASSES的頂部 - 在這種情況下，他總是'ru'。我試過使用django.conf.urls.i18n，translation.activate（）和許多其他的東西，但無濟於事。請告訴我一些，我做錯了什麼？這裏提供
