django i18n_patterns隱藏URL的默認lang_code

Question

我正在使用i18n_patterns將當前lang_code的前綴添加到我的網址。

urlpatterns += i18n_patterns('', 
    url(r'^', include('blaszczakphoto2.gallery.urls')), 
) 

這allowes我得到的URL像/en/about-us/，/pl/about-us/等。 我的默認語言爲pl

LANGUAGE_CODE = 'pl' 

我想網址喜歡/美國/客戶端瀏覽我的網站在拋光lenguage 。有沒有什麼辦法可以從默認lang_code的url中隱藏lang_code前綴？

Answer 1

這是我的解決方案：

創建Django的中間件：django_app/lib目錄/中間件/ locale.py

from django.utils import translation 

    class SwitchLanguageMiddleware(object): 

     def process_request(self, request): 
      lang = request.GET.get('lang', '') 

      if lang: 
       translation.activate(lang) 
       request.LANGUAGE_CODE = translation.get_language() 

     def process_response(self, request, response): 
      request.session['django_language'] = translation.get_language() 
      if 'Content-Language' not in response: 
       response['Content-Language'] = translation.get_language() 
      translation.deactivate() 

      return response 

它的讀取請求的GET參數，而且如果它有lang屬性，然後切換語言。例：/約-US/LANG = PL

包含此中間件的settings.py：

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

    'django_app.libs.middleware.locale.SwitchLanguageMiddleware', 
)

我面對這個問題，解決了這個辦法：

• 創建一種替代i18n_patterns，它們不以站點主要語言爲前綴（在settings.LANGUAGE_CODE中定義）。

• 創建了一個只使用URL前綴語言激活當前語言的替代中間件。

我沒有看到使用這種技術的任何副作用。

代碼：

# coding: utf-8 
""" 
Cauê Thenório - cauelt(at)gmail.com 

This snippet makes Django do not create URL languages prefix (i.e. /en/) 
for the default language (settings.LANGUAGE_CODE). 

It also provides a middleware that activates the language based only on the URL. 
This middleware ignores user session data, cookie and 'Accept-Language' HTTP header. 

Your urls will be like: 

In your default language (english in example): 

    /contact 
    /news 
    /articles 

In another languages (portuguese in example): 

    /pt/contato 
    /pt/noticias 
    /pt/artigos 

To use it, use the 'simple_i18n_patterns' instead the 'i18n_patterns' 
in your urls.py: 

    from this_sinppet import simple_i18n_patterns as i18n_patterns 

And use the 'SimpleLocaleMiddleware' instead the Django's 'LocaleMiddleware' 
in your settings.py: 

    MIDDLEWARE_CLASSES = (
    ... 
     'this_snippet.SimpleLocaleMiddleware' 
    ... 
    ) 

Works on Django >=1.4

你可能要檢查yawd-translations這正是這麼做的。如果您不關心額外的功能（從db管理語言），您可以查看urls.translation_patterns方法和middleware.TranslationMiddleware以查看如何完成。

Answer 4

這是一個非常簡單的包：django-solid-i18n-urls

設置後，沒有語言前綴的網址將始終使用默認語言，也就是在settings.LANGUAGE_CODE規定。重定向不會發生。

如果url將有語言前綴，那麼將使用該語言。

Answer 5

Django >=1.10可以處理這個本地。在i18n_patterns函數中有一個新的prefix_default_language參數。

設置prefix_default_language到False從 刪除前綴的默認語言（LANGUAGE_CODE）。將 翻譯添加到現有網站以便當前網址不會更改時，這非常有用。

來源：https://docs.djangoproject.com/en/dev/topics/i18n/translation/#language-prefix-in-url-patterns

實施例：

# Main urls.py: 
urlpatterns = i18n_patterns(
    url(r'^', include('my_app.urls', namespace='my_app')), 
    prefix_default_language=False 
) 

# my_app.urls.py: 
url(r'^contact-us/$', ...), 

# settings: 
LANGUAGE_CODE = 'en' # Default language without prefix 

LANGUAGES = (
    ('en', _('English')), 
    ('cs', _('Czech')), 
) 

的example.com/contact-us/的響應將是在英國和捷克example.com/cs/contact-us/。
