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')),
)

它允许我获取/en/about-us/，/pl/about-us/等网址。我的默认语言为pl

LANGUAGE_CODE = 'pl'

我希望url喜欢/ about-us /用于在波兰语中查看我的网站的客户。有没有办法从url隐藏lang_code前缀以获取默认的lang_code？

Answer 1

这是一个非常简单的包：django-solid-i18n-urls

设置完成后，没有语言前缀的网址将始终使用settings.LANGUAGE_CODE中指定的默认语言。重定向不会发生。

如果url具有语言前缀，则将使用该语言。

我遇到了这个问题并以这种方式解决了：

创建了一个替代i18n_patterns，它不以网站主要语言为前缀（在settings.LANGUAGE_CODE中定义）。
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'
    ...
    )

您可能需要检查yawd-translations哪个确实如此。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以了解如何完成。

这是我的解决方案：

创建django中间件：django_app / lib / middleware / 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

它读取了请求的get参数，如果它有lang属性，则切换语言。例如：/ about-us /？lang = pl

将此中间件包含到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',
)

django i18n_patterns隐藏来自url的默认lang_code
