Django makemessage命令不处理应用程序

Question

我正在尝试国际化 django 应用程序。我遵循了教程，但是当我运行时...

./manage.py makemessages --all

... django 只创建一个 .po 文件，其中包含我的 settings.py 的翻译（见下文）。它完全忽略了我的应用程序及其模板中的任何内容。

这是我的文件结构：

myproject
  |- myproject
      |- course
          |- templates
          |- static
          |- ...
          |- apps.py
          |- models.py
          |- views.py
          |- ...
      |- locale
      |- myproject
          |- settings.py
          |- ...
      |- manage.py

我的设置文件如下所示：

from django.utils.translation import ugettext_lazy as _

...

INSTALLED_APPS = [
     ...
     'course.apps.CourseConfig',
]

MIDDLEWARE_CLASSES = [
    ...
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.locale.LocaleMiddleware',
    'django.middleware.common.CommonMiddleware',
    ...
]

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': False,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.i18n',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

LANGUAGE_CODE = 'en-us'
TIME_ZONE = 'CET'
USE_I18N = True
USE_L10N = True
USE_TZ = True


LANGUAGES = [
    ('en', _('English')),
    ('kr', _('Korean')),
    ('cn', _('Chinese')),
    ('pt', _('Portuguese')),
]

LOCALE_PATHS = (
    os.path.join(BASE_DIR, 'locale'),
)

我的模板包含翻译文本：

{% extends "course/base.html" %}

{% load i18n %}    
{% trans "Back to modules" %}
...

如果我运行 'makemessages' 命令，.po 文件中唯一包含的是 settings.py 文件中的语言名称，而不是模板变量或我在视图中用 ugettext 翻译的任何内容。

msgid "Chinese"
msgstr ""

谁能告诉我缺少什么？该应用程序运行良好，所有模板都在运行时找到。非常感谢。

我终于找到了“问题”。我不得不进入我的 django 应用程序的目录，course然后../manage.py makemessages -l en再次从那里运行等。然后，创建了文件并且一切正常。Django 文档并没有明确说明我必须cd进入我的每个应用程序。
