RuntimeError: Model class Moonstargram.notifications.models.Notification doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

다음과 같은 에러로그가 발생했는데..

from django.apps import AppConfig

class NotificationsConfig(AppConfig):

name = 'notifications'

앱의 이름이 정확한 위치를 가리키고 있지 않아서 이다.

from django.apps import AppConfig

class NotificationsConfig(AppConfig):

name = 'Moonstargram.notifications'

다음과 같이 해결하였다.
