Python Migrate issue

/ By / Category: Code

I encountered an error whilst building an application in Python this morning, I had the feeling that it would be a naming issue and a Stackoverflow post confirmed this.

The problem arose when attempting to build a model migration file using makemigrations

python manage.py makemigrations

Which returned the following error:

django.core.exceptions.ImproperlyConfigured: Cannot import 'apps.accounts'. Check that 'mysite.apps.accounts.apps.AccountsConfig.name' is correct.

The solution? The name in apps.py should be the same value that you put in INSTALLED_APPS in settings.py:

apps.py

from django.apps import AppConfig

class AccountsConfig(AppConfig):
    default_auto_field = "django.db.models.BigAutoField"
    name = "mysite.apps.accounts"

settings.py

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'mysite.apps.accounts',
]
