Restructure default hierarchy of Django project, moving all apps into a folder with custom model

Question

I am trying to move all the apps that I have in my Django application to a folder call apps:

The structure that I have right now is:

miApp
-accounts #App folder
-participation #App folder
-administration #App folder

-miapp 
--wsgi.py
--urls.py
--settings
---development.py
---production.py
---__init__.py
-static

And I would like to have something like this

miApp
-apps #New folder for the apps
--accounts #App folder
--reputation #App folder
--participation #App folder
--administration #App folder
--__init__.py
-miApp 
--wsgi.py
--urls.py
--settings
---common.py #Common settings for develpment and production
---development.py
---production.py
---__init__.py
-static
...

I tried already to move them all to the same folder,

I did the following change in miApp.urls

path('', views.inicio, name='inicio'),
path('admin/', admin.site.urls),
path('cuentas/', include('apps.accounts.urls')),
path('participation/', include('apps.participation.urls')),
path('administracion/', include('apps.administration.urls')),

And also this, in the settings of common.py

DJANGO_APPS = ['django.contrib.admin',
                'django.contrib.auth',
                'django.contrib.contenttypes',
                'django.contrib.sessions',
                'django.contrib.messages',
                'django.contrib.staticfiles',
                'django.contrib.sites'
               ]
THIRD_PARTIES = [# Django AllAuth
                'allauth',
                'allauth.account',
                'allauth.socialaccount',
                'allauth.socialaccount.providers.facebook',
                'allauth.socialaccount.providers.google',
                'allauth.socialaccount.providers.twitter',
                # Django guardian
                'guardian',
                #Django meta
                'meta',
                # Django push notifications
                'push_notifications',
                ]

MI_APP_APPS = [# MyVoto Instaled apps
                'apps.accounts.apps.AccountsConfig',
                'apps.participation.apps.ParticipationConfig',
                'apps.administration.apps.AdministrationConfig']

INSTALLED_APPS = DJANGO_APPS + THIRD_PARTIES + MI_APP_APPS

I have the following config classes in apps.py

class AccountsConfig(AppConfig):
    name = 'apps.accounts'

class AdministrationConfig(AppConfig):
    name = 'apps.administration'

class ParticipationConfig(AppConfig):
    name = 'apps.participation'

And I am getting the following error:

Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x107afa488>

During handling of the above exception, another exception occurred:

I have the following in apps.accounts.apps.py

class AccountsConfig(AppConfig): name = 'accounts'

You did not publish the content of your Config classes. – Cyrlop Jul 16 '18 at 13:27 — Cyrlop, Jul 16 '18 at 13:27

I think that's not a good practice to move apps folders this way but did you try to add a __init__.py file in apps?

miApp
-apps #New folder for the apps
--accounts #App folder
--reputation #App folder
--participation #App folder
--administration #App folder
--__init__.py

EDIT
Ithink the problem is the location of your apps.py file. From what you have in INSTALLED_APPS, it tries to get your config classes from an apps.py in every app folder.

Check this answer, the guy describes exactly what you're trying to do.
Really make sure you have the __init__.py file inside your apps folder and inside each app folder.

Move your apps
Change your prefix your apps in INSTALLED_APPS and urls.py by apps.

Yes , I have the __init__.py file , I forgot to add it in the schema – Roberto Fernandez Diaz Jul 16 '18 at 11:29
Do you get the same error if you replace `apps..apps.` by `apps.` in your installed apps? – Cyrlop Jul 16 '18 at 13:26

The problem was that as I am using a custom user model in my common.py I had this:

AUTH_USER_MODEL = 'accounts.User'

With the changes I was doing, I also add the prefix apps to this setting, don't know why this setttings it works different, but instead of adding the prefix apps I had to leave it like it was before.

I think it maybe cause of the initial migration, that some how as is in the initial migration where the custom model is set up, probably the route is store somewhere and that maybe the thing causing the problem
