Make startapp generate an apps.py

[Tim Graham]

I guess it might look like:

from django.apps import AppConfig

class AppnameConfig(AppConfig):
    name = 'appname'

and in __init__.py: default_app_config = 'appname.apps.AppnameConfig'

I reviewed the ​PR.

Fixed #24971 -- Made startapp generate an apps.py

[James Beith]

I just tested this with Django 1.9rc1 and the default_app_config statement was not added to the __init__.py file, the file was blank.

I noticed this first in my own project but also in a blank test project.

Steps

• Created a new Python 3.4 virtualenv
• Installed Django 1.9rc1 via pip
• Ran django-admin startproject mysite
• Ran python manage.py startapp polls from within the project

Expected Behaviour

• An apps.py file is created with appropriate content
• An __init__.py file is created with appropriate default_app_config statement

Actual Behaviour

• An apps.py file is created with appropriate content
• An __init__.py file is created but no default_app_config statement is included, the file is blank

[Tim Graham]

That's intentional, see #25356.

[Tim Graham]

That said, how about ​a small enhancement to the 1.9 release notes to clarify the expected behavior?

[James Beith]

Yeah I think so. Especially if using default_app_config is discouraged, I wasn't aware of this.
