没有路径前缀的Django i18n默认语言
我有一个要移植到Django 1.4的现有多语言Django应用程序。I18n支持目前基于一些丑陋的技巧，我想使其使用Django的内置i18n模块。
一个约束是我不想更改已经存在的URL。这个网站已经活跃了一段时间，并且有一些我不想破坏或重定向的外部链接。url方案的工作原理如下：英语内容位于网站的根目录，而其他语言则在域名中使用前缀：
英文网址：
//articles/
/suggestions/
西班牙语网址：
/es//es/articulos/
/es/sugerencias/
我已经将翻译后的页面与Django 1.4的i18n模块一起使用，但是它确实非常希望将所有英文url放在/ en /下。我尝试了几种不同的技巧，包括为英语版本定义了非国际化的URL：
def build(callback): return callback('',
url(_(r'^$'), home.index, name="home"),
url(_(r'^articles/$'), content.article_list, name='article_list'),
url(_(r'^suggestions/$'), suggestions.suggestions, name='suggestions'),
)
urlpatterns = build(patterns)
urlpatterns += build(i18n_patterns)
这样可以正确解析网址，但是{％url％}标签无法进行反向解析。
回答：
请看下面的答案，Django 1.10本身支持它
我遇到了这个问题并以这种方式解决了：
创建了一个
i18n_patterns不加前缀网站主要语言（在中定义settings.LANGUAGE_CODE）的替代方法。创建了仅使用URL前缀语言来激活当前语言的备用中间件。
使用此技术我没有看到任何副作用。
代码：

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
