问题描述
我们有一个支持多种语言的Django网站.尝试添加对多种语言的opensearch插件支持.
We have a Django site that supports many languages. Trying to add opensearch plug-ins support for multi-language.
OpenSearch.org规范使用 IETF语言标记(xx-YY格式).默认的Django设置使用完全匹配.
OpenSearch.org spec uses IETF language tag (xx-YY format). Default Django setup uses exact matching.
-
当前状态,该站点仅支持xx形式的其他任何内容,返回E404.示例:
The current state, the site support only xx form anything else return E404. Example:
http://website.domain/en/...
根据用户配置,浏览器将插入语言参数为xx或xx-YY.它需要对两者都起作用
Depending on user configuration the browser insert language parameter as xx or xx-YY. It needs to work for both
- 如果
xx-YY
不可用,则网站应提供xx
(母语). - 如果
xx
不可用,则网站应提供en
(英文)结果.
- If
xx-YY
is not available, site should providexx
(mother country language) results. - if
xx
is not available, site should provideen
(English) results.
要支持的网址示例:
http://website.domain/fr-YY/...
fall-back to: http://website.domain/fr/...
http://website.domain/xx/...
fall-back to: http://website.domain/en/...
Mozilla网站的示例URL: https://support.mozilla.org/en-US/questions/949545
Example URL from Mozilla site:https://support.mozilla.org/en-US/questions/949545
如何使Django支持IETF语言标记(xx-YY格式)?我什至在寻找无需修改django上游代码即可实现此目标的提示.
How to make Django support IETF language tag (xx-YY format)? I'm looking even for hints to implement this without modifying the django upstream code.
更新:
好吧,官方文档明确表示应该退后(例如:en-us to en),但我的案子引发了404错误.
Well, official documentation says clearly it should fall-back (ex: en-us to en) but my case raises 404 error.
来源: https://django.readthedocs.io/en/1.5.x/topics/i18n/translation.html
...
语言=(('de',_('German')),('en',_('English')),)
LANGUAGES = ( ('de', _('German')), ('en', _('English')), )
此示例将可用于自动选择的语言限制为德语和英语(以及任何副语言,例如de-ch或en-us).
This example restricts languages that are available for automatic selection to German and English (and any sublanguage, like de-ch or en-us).

推荐答案
据我所知,Django i18n确实支持将 xx-YY
转换为 xx
然后设置为默认值(在我的情况下为 en
),但仅适用于 Accept-Language
用户代理标头.URL语言切换与之不同.
Well as far I can test, Django i18n does supports fall-back xx-YY
to xx
then to default (en
in my case) but only for Accept-Language
user agent header. It does not do same for URL language switch.
这是我可以提出的解决方案:
Here is the solution I could come up with:
from django.views.generic import RedirectView
from django.conf import settings
...
urlpatterns += patterns('',
url(r'^(?P<lang>[a-z]{2})-[A-Za-z]{2}/(?P<path>.*)$', RedirectView.as_view(url='/%(lang)s/%(path)s',query_string=True)),
url(r'^[a-z]{2}/(?P<path>.*)$', RedirectView.as_view(url='/{}/%(path)s'.format(settings.LANGUAGE_CODE),query_string=True)),
)
- 任何未由i18n模式处理的
xx-YY
都已重定向到xx
- 任何未由i18n模式处理的
xx
都重定向为使用LANGUAGE_CODE
设置的默认语言. - Any
xx-YY
not handled by i18n pattern redirected toxx
- Any
xx
not handled by i18n pattern redirected to default language set usingLANGUAGE_CODE
.
