我制作了一个简单的本地化应用程序（django 2.2.4）。我建立了一种改变语言的方法，并在当我在本地使用

python manage.py runserver

它工作得很好，但当我在不同的ubuntu服务器上通过nginx和gunicorn运行它时，我得到了

Exception while resolving variable 'redirect_to' in template 'home/index.html'.

您可以在此处找到解决方案：

我解决问题的方法如下：

记住，在siting.py中，您必须添加

'django.middleware.locale.LocaleMiddleware',

未来的中间件

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
   'django.middleware.locale.LocaleMiddleware',

]

此外，您还必须添加您的语言列表

_ = lambda s: s
LANGUAGES = (
    ('en', _('English')),
    ('ar', _('Arabic')),  

)

在url.py中，您的conde必须如下所示：

from django.conf.urls.i18n import i18n_patterns 
urlpatterns = [
url('admin/', admin.site.urls),
                path('', include('document_control.urls')),
            ] + static(settings.STATIC_ROOT
                        ,document_root=settings.MEDIA_ROOT)

urlpatterns += i18n_patterns( 
#url('admin/', admin.site.urls), 

url('', include('document_control.urls')), 

prefix_default_language=True, ) + static(settings.STATIC_ROOT
        ,document_root=settings.MEDIA_ROOT) #for active static files

在模板中，您的代码必须如下所示

{% load i18n %}
<ul class="nav navbar-nav navbar-right language menu">
    {% get_current_language as LANGUAGE_CODE %}
    {% get_available_languages as LANGUAGES %}
    {% get_language_info_list for LANGUAGES as languages %}
    {% for language in languages %}
        <li>
            <a href="/{{ language.code }}{{ request.get_full_path|slice:'3:' }}"
               class="{% if language.code == LANGUAGE_CODE %}selected{% endif %}"
               lang="{{ language.code }}">
                {{ language.name_local }}
            </a>
        </li>
    {% endfor %}
</ul>    




{% if   LANGUAGE_CODE  == "ar" %}
your code by arabic language
{% else %}
you code by english language


{% endif %}

{%loadi18n%}

{%get_当前语言为语言代码%}
{%get_可用语言为语言%}
{%get_language_info_list for LANGUAGES as LANGUAGES%}
{%用于语言中的语言%}


{%endfor%}

{%if LANGUAGE_CODE==“ar”%}
你的代码是用阿拉伯语写的
{%else%}
你用英语编码
{%endif%}

我希望它对您有用
