Django i18n默认语言没有路径前缀 [英] Django i18n default language without path prefixes
问题描述
一个约束是我不想更改已经存在的网址。该网站已经活动了一段时间，并且有外部链接，我不想打破或重定向。网址计划的工作方式如下：英文内容是网站的根，而其他语言在域名中使用前缀：
英文urls：
/
/ articles /
/ suggestions /
西班牙语urls：
/ es /
/ es /我已经将翻译的页面与Django配合使用了。 1.4的i18n模块，但真的，真的想把所有的英文网址放在/ en /下。我尝试了一些不同的黑客，包括为英文版定义非国际化网址： def build（callback）：
return callback（''，
url（_（r'^ $'），home.index，name =home），
url（_（r'^ articles / $ '），content.article_list，name ='article_list'），
url（_（r'^ suggestions / $'），suggest.suggestions，name ='suggestions'），
）
urlpatterns = build（patterns）
urlpatterns + = build（i18n_patterns）
这样可以正确解析网址，但反向解析的{％url％}标签不起作用。
完成非前缀英语网址的最佳方式是什么？
解决方案 更新：阅读下面的回答，Django 1.10本身支持
我遇到这个问题，解决了这个问题：
-
创建了一个替代的 i18n_patterns ，它不在站点主要语言前面（在 settings.LANGUAGE_CODE ）。
-
创建了一个替代中间件，仅使用URL前缀语言来激活当前
我没有看到使用这种技术的任何副作用。
代码：
＃编码：utf-8
CauêThenório - cauelt（at）gmail.com
此代码段使Django不为默认语言（settings.LANGUAGE_CODE）创建URL语言前缀（即/ en /）
它还提供了一个激活langu的中间件年龄仅基于网址。
此中间件忽略用户会话数据，cookie和Accept-LanguageHTTP头。
您的网址将如下所示：
在您的默认语言（例如英语）中：
/ contact
/ news
/ articles
在另一种语言（例如葡萄牙语）中：
/ pt / contato
/ pt / noticias
/ pt / artigos
要使用它，请使用'simple_i18n_patterns'代替'i18n_patterns'
在您的urls.py：
from this_sinppet import simple_i18n_patterns as i18n_patterns
使用SimpleLocaleMiddleware代替Django的LocaleMiddleware
在您的settings.py中：
MIDDLEWARE_CLASSES =（
...
'this_snippet。 SimpleLocaleMiddleware'
...
）

I have an existing multi-lingual Django app that I'm porting to Django 1.4. I18n support is currently based on some ugly hacks, I'd like to make it use Django's built-in i18n modules.
One constraint is that I don't want to change the urls that are already in place. This site has been active for a while and there are external links to it that I dont' want to break or redirect. The urls scheme works like this: English content is at the root of the site, while other languages use prefixes in the domain name:
English urls:
/
/articles/
/suggestions/
Spanish urls:
/es/
/es/articulos/
/es/sugerencias/
I've got the translated pages working with Django 1.4's i18n modules, but it really, really, really wants to put all the English urls under /en/. I've tried a few different hacks, including defining non-internationalized urls for the English version:
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)
This makes the urls resolve properly, but the {% url %} tag to do reverse resolution doesn't work.
What's the best way to accomplish non-prefixed English-language urls?
解决方案 UPDATE: Read answer bellow, Django 1.10 supports it natively
I faced this problem and solved this way:
Created an alternative i18n_patterns that do not prefix the site main language (defined in settings.LANGUAGE_CODE).
Created an alternative middleware that only uses the URL prefixes language to activate the current language.
I didn't see any side-effect using this technique.
The code:
# 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
