为什么这个表格不会改变网站的语言？

Question

这是我的语言转换表格。

{% get_current_language as lang_code %}
{% get_available_languages as languages %}
{% get_language_info_list for languages as langs %}
<form action="{% url 'set_language' %}" method="POST">
{% csrf_token %}
<select name="language" title="{% translate 'Language' %}">
{% for lang in langs %}
<option value="{{ lang.code }}"{% if lang.code == lang_code %} selected{% endif %}>
{{ lang.name_local }} ({{ lang.name_translated }})
</option>
{% endfor %}
</select>
<input type="submit" value="OK" />
</form>

我将它包含在我的基本模板的页脚中。

然后，这是我的课程/urls.py（应用程序网址）。

from django.contrib import admin
from django.urls import path
from django.utils.translation import gettext_lazy as _
from . import views

admin.site.site_header = _("FilFak administration")
admin.site.site_title = _("FilFak admin")
admin.site.index_title = _("Manage FilFak")

urlpatterns=[
    path("courses/", views.CourseList.as_view(), name="course_list"),
    path("professors/", views.ProfessorList.as_view(), name="professor_list"),
    path("exams/", views.ExamList.as_view(), name="exam_list"),
    path("courses/<slug:slug>", views.CourseDetails.as_view(), name="course_details"),
    path("professors/<slug:slug>", views.ProfessorDetails.as_view(), name="professor_details"),
    path("exams/<slug:slug>", views.ExamDetails.as_view(), name="exam_details"),
    path("", views.Index.as_view(), name="index"),
]

filfak/urls.py（项目 urls.py）

from django.contrib import admin
from django.urls import path, include
from django.conf.urls.i18n import i18n_patterns
from django.conf.urls.static import static
from django.conf import settings
from django.utils.translation import gettext_lazy as _

urlpatterns = [
    path("admin/", admin.site.urls),
    path("lang/", include("django.conf.urls.i18n")),
]

urlpatterns += i18n_patterns(
    path("", include("courses.urls")),
    prefix_default_language=False
)

urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

这是来自 settings.py 的中间件列表。

MIDDLEWARE = [
    "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",
]

当我在语言切换表单上单击“确定”时，它实际上只在默认语言的主页上更改了语言。在任何其他 URL 上，它只是刷新页面，而不更改语言。

我是不是做错了什么？

检查USE_I18N的标志值，看起来它设置为False，这就是语言设置不正确的原因。

将其更改为：-

USE_I18N = True

根据 Django 文档：-

如果你不使用国际化，你应该花两秒钟在你的设置文件中设置 USE_I18N = False。
