If you have problems with translating strings:

• read How Django discovers translation https://docs.djangoproject.com/en/1.5/topics/i18n/translation/#how-django-discovers-translations
• Define in your settings.py to make sure that strings are first read from the directory defined by you:
  • BASEPATH = realpath(join(dirname(_file), '..'))
  • LOCALE_PATHS = (
  • join(BASE_PATH, 'locale'),
  • )
