Django：i18n - 更改语言

我安装了 model_translation、rosetta、locale_url。但改变语言不起作用。

我的设置.py：

LANGUAGE_CODE = 'ru'
MODELTRANSLATION_TRANSLATION_REGISTRY = "project.translation"
TRANSLATION_REGISTRY = "project.translation"
ugettext = lambda s: s
LANGUAGES = (
    ('ru', ugettext(u'Russian')),
    ('uk', ugettext(u'Ukrainian')),
)

我对语言切换的看法：

def set_language(request):
    next = request.REQUEST.get('next', None)
    if not next:
        next = request.META.get('HTTP_REFERER', None)
    if not next:
        next = '/'
    response = http.HttpResponseRedirect(next)
    if request.method == 'GET':
        lang_code = request.GET.get('language', None)
        if lang_code and check_for_language(lang_code):
            if hasattr(request, 'session'):
                request.session['django_language'] = lang_code
            else:
                response.set_cookie(settings.LANGUAGE_COOKIE_NAME, lang_code)
    return response

在模板中：

<a href="{% url set_lang %}?lang=uk&next={{request.path}}">Ukranian</a>

我的中间件：

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.middleware.locale.LocaleMiddleware',
    'localeurl.middleware.LocaleURLMiddleware',
    'django.middleware.common.CommonMiddleware',  
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.middleware.csrf.CsrfResponseMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
)

但语言切换不起作用。如果我打开链接http://localhost/uk/语言开关，但是当切换到另一个页面时-语言又恢复为默认语言。 我应该怎么办？

将 Translation.activate 添加到您的代码中：

from django.utils import translation

def set_language(request):
    next = request.REQUEST.get('next', None)
    if not next:
        next = request.META.get('HTTP_REFERER', None)
    if not next:
        next = '/'
    response = http.HttpResponseRedirect(next)
    if request.method == 'GET':
        lang_code = request.GET.get('language', None)
        if lang_code and check_for_language(lang_code):
            if hasattr(request, 'session'):
                request.session['django_language'] = lang_code
            else:
                response.set_cookie(settings.LANGUAGE_COOKIE_NAME, lang_code)
            translation.activate(lang_code)
    return response
