Django i18n没有路径前缀的默认语言

Question

我有一个现有的多语言Django应用程序,我正在移植到Django 1.4.I18n支持目前基于一些丑陋的黑客,我想使用Django的内置i18n模块.

一个限制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,并且有一些外部链接,我不想打破或重定向.网址方案的工作方式如下:英文内容位于网站的根目录,而其他语言则使用域名中的前缀:

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模块配合使用了,但它确实非常非常希望将所有英文网址放在/ 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的网址:

def build(callback):
  return callback('',
    url(_(r'^$'), home.index, name="home"),
    url(_(r'^articles/$'), content.article_list, name='article_list'),
    url(_(r'^suggestions/$'), suggestions.suggestions, name='suggestions'),
  )

urlpatterns = build(patterns)
urlpatterns += build(i18n_patterns)

这使得网址正确解析,但执行反向解析的{%url%}标记不起作用.

完成非前缀英语网址的最佳方法是什么？

我使用solid-i18n-url来解决类似的问题:https: //github.com/st4lk/django-solid-i18n-urls

Answer 2

Django 1.10原生支持它.正如他们在文档中所说:

i18n_patterns(*urls,prefix_default_language = True)

此函数可以在根URLconf中使用,Django会自动将当前活动语言代码添加到其中定义的所有url模式中i18n_patterns().

将prefix_default_language设置为False将从默认语言(LANGUAGE_CODE)中删除前缀.将翻译添加到现有网站时,此功能非常有用,这样当前网址就不会更改.

更新:阅读下面的答案,Django 1.10原生支持它

我遇到了这个问题并解决了这个问题:

• 创建了一个i18n_patterns不为网站主要语言(在中定义settings.LANGUAGE_CODE)添加前缀的替代方法.

• 创建了一个替代中间件,它只使用URL前缀语言来激活当前语言.

我没有看到使用这种技术的任何副作用.

代码:

# coding: utf-8
"""

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
