title: Django makemessage command not processing app
body: <p>I'm trying to internationalize a django application. I followed the tutorial, but when i run ...</p>
  
  <pre><code>./manage.py makemessages --all
  </code></pre>
  
  <p>... django only creates a .po file that contains the translations of my settings.py (see below). It completely ignores anything inside my app and its templates.</p>
  
  <p>This is my file structure:</p>
  
  <pre><code>myproject
    |- myproject
        |- course
            |- templates
            |- static
            |- ...
            |- apps.py
            |- models.py
            |- views.py
            |- ...
        |- locale
        |- myproject
            |- settings.py
            |- ...
        |- manage.py
  </code></pre>
  
  <p>My settings file looks like this:</p>
  
  <pre><code>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'),
  )
  </code></pre>
  
  <p>My templates contain translation texts:</p>
  
  <pre><code>{% extends "course/base.html" %}
  
  {% load i18n %}    
  {% trans "Back to modules" %}
  ...
  </code></pre>
  
  <p>If I run the 'makemessages' command, the only thing that's being included in the .po file is the language names in the settings.py file, but not the template variables or anything I translated with ugettext in a view.</p>

  <p>Can anyone tell what I'm missing? The app works just fine, all templates are found at runtime. Thanks a lot.</p>
