虽然设置了 dgango_language cookie，但 django 翻译不起作用

Question

已经三天了，我已经厌倦了。 这是我的设置文件：

from pathlib import Path
from django.utils.translation import gettext_lazy as _

# Build paths inside the project like this: BASE_DIR / 'subdir'.
BASE_DIR = Path(__file__).resolve().parent.parent


# Quick-start development settings - unsuitable for production

    "mainapp",

MIDDLEWARE = [

DEFAULT_AUTO_FIELD = "django.db.models.BigAutoField"

如您所见，我尝试将“django.middleware.locale.LocaleMiddleware”添加到 MIDDLEWARE 并将“django.template.context_processors.i18n”添加到内容处理器。

网址：

from django.contrib import admin
from django.urls import path, include
from mainapp import views

urlpatterns = [
    path('contact/', views.SendMessage.as_view()),
    path("admin/", admin.site.urls),
    path('about/', views.about),
    path('articles/<int:id>/', views.ShowArticlesView.as_view()),
    path('articles/', views.ArticlesListView.as_view()),
    path('projects/<int:id>/', views.ShowProjectView.as_view()),
    path('projects/', views.ProjectsListView.as_view()),
    path('i18n/',include('django.conf.urls.i18n')),
    path('', views.home),
]

浏览次数：

def home(request):
    return render(request, 'home.html')

区域设置文件：

                    django.po

                   django.po
                   django.mo

msgstr "فارسی"

#: .\templates\home.html:6
msgid "Hello"
msgstr "سلام"

home.html：

{% load i18n %}
<form action="{% url 'set_language' %}" method="post">{% csrf_token %}
    <input name="language" type="hidden" value="fa"/>
    <input type="submit" value="change"/>
</form>
{% trans "Hello" %}

当我检查浏览器 cookie 时，djngo_language 设置为“fa”，但它不会将“Hello”一词翻译为“Săram”：

我尝试了

manage.py makemessages --all

和

manage.py compilemessages

数百次。我尝试了在互联网上找到的所有解决方案，但没有一个有效。然后我删除了我的项目并将其所有代码移至一个新项目，但这也不起作用。我什至尝试以不同的方式多次重新安装 gettext。我还尝试使用 {% blocktrans %}{% endblocktrans %} 而不是 trans 标签。我简直要疯了

我希望 django 将“Hello”翻译为“Săram”

Answer 1

您使用什么版本的 Django？

trans

HTML 模板标签似乎不再使用，在 4.x 文档中

translate

是示例中标签的名称。

我也会检查这个，以防万一它与

Accept-Language

HTTP 标头有关。

Answer 2

'django.middleware.locale.LocaleMiddleware'

应放置在

"django.contrib.sessions.middleware.SessionMiddleware"

和

"django.middleware.common.CommonMiddleware"

之间，因此您的

MIDDLEWARE

设置应如下所示：

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