24801	AppConfigs aren't loaded when the application is in a nested directory	Josh Smeaton	nobody	"We had someone in IRC trying to use a custom AppConfig with an application that was installed to a subdirectory called ""apps"". The AppConfig wasn't being picked up, and the import_module machinery was throwing errors. I've replicated this locally too.

Application at: project/top/drill/

{{{

INSTALLED_APPS = [
    'top.drill',  # with default_app_config 
    'top.drill.apps.DrillConfig',  # without default_app_config
]

Problem happens using default_app_config or by referencing the AppConfig from INSTALLED_APPS. I suspect there's a problem related to importing modules when the application isn't in the project root directory.

I think that https://code.djangoproject.com/ticket/23470 was the same problem, but it was never fully investigated."	Bug	closed	Core (Other)	dev	Normal	invalid			Unreviewed	0	0	0	0	0	0
