django i18n_patterns隐藏URL的默认lang_code

Question

我正在使用i18n_patterns将当前lang_code的前缀添加到我的网址。

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

这allowes我得到的URL像/en/about-us/，/pl/about-us/等。 我的默认语言为pl

LANGUAGE_CODE = 'pl' 

我想网址喜欢/美国/客户端浏览我的网站在抛光lenguage 。有没有什么办法可以从默认lang_code的url中隐藏lang_code前缀？

Answer 1

这是我的解决方案：

创建Django的中间件：django_app/lib目录/中间件/ 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 

它的读取请求的GET参数，而且如果它有lang属性，然后切换语言。例：/约-US/LANG = PL

包含此中间件的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', 
)

我面对这个问题，解决了这个办法：

• 创建一种替代i18n_patterns，它们不以站点主要语言为前缀（在settings.LANGUAGE_CODE中定义）。

• 创建了一个只使用URL前缀语言激活当前语言的替代中间件。

我没有看到使用这种技术的任何副作用。

代码：

# 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

你可能要检查yawd-translations这正是这么做的。如果您不关心额外的功能（从db管理语言），您可以查看urls.translation_patterns方法和middleware.TranslationMiddleware以查看如何完成。

Answer 4

这是一个非常简单的包：django-solid-i18n-urls

设置后，没有语言前缀的网址将始终使用默认语言，也就是在settings.LANGUAGE_CODE规定。重定向不会发生。

如果url将有语言前缀，那么将使用该语言。

Answer 5

Django >=1.10可以处理这个本地。在i18n_patterns函数中有一个新的prefix_default_language参数。

设置prefix_default_language到False从 删除前缀的默认语言（LANGUAGE_CODE）。将 翻译添加到现有网站以便当前网址不会更改时，这非常有用。

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

实施例：

# 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/的响应将是在英国和捷克example.com/cs/contact-us/。
