Джанго ImproperlyConfigured исключение при выполнении команды из Джанго-администратора, но не manage.py

Question

Когда я бег django-admin migrate, я получаю следующее сообщение об ошибке:

Traceback (most recent call last):

django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. 

То же команда на администраторе; р: python admin.py работает отлично. Я предполагаю, что это означает, что я могу просто использовать admin.py, но я хотел бы понять, почему django-admin не находит конфигурацию моего приложения. Какой процесс он использует? В чем может быть проблема?

Answer 1

У вас есть ошибка, потому что при запуске django-admin он не знает, какой модуль настроек использовать. Вы можете указать его через переменную evironment, как предложено в сообщении об ошибке, или просто использовать manage.py в вашем проекте.

django-admin is Django’s command-line utility for administrative tasks.

In addition, manage.py is automatically created in each Django project. manage.py does the same thing as django-admin but takes care of a few things for you:

• It puts your project’s package on sys.path.
• It sets the DJANGO_SETTINGS_MODULE environment variable so that it points to your project’s settings.py file.
