Module Not Found Error after forking the oscar app

[ayo femi]

Am experiencing module not found error after forking the oscar catalogue app. 

Tried adding the forked app to get_core_apps in the settings file, running python manage.py runserver returns  No module name 'apps', which was where i created catalogue app. The __init__.py is present in the apps folder and catalogue.

Meanwhile, an not getting this error for other apps in the same folder added to the INSTALLED_APPS

I have no clue of what might be wrong.

Enter code here...

from oscar import get_core_apps

INSTALLED_APPS = [

'django.contrib.admin',

'django.contrib.auth',

'django.contrib.contenttypes',

'django.contrib.sessions',

'django.contrib.sites',

'django.contrib.messages',

'django.contrib.staticfiles',

'django.contrib.flatpages',

# 'clue.apps.my_products',

'elasticsearch5',

# 'debug_toolbar',

    'compressor',

    'widget_tweaks',

] + get_core_apps(['clue.apps.catalogue'])

What version of Oscar are you using? Also please share the full stack trace.

I have Django Oscar 1.6.7 installed in my environment.

Django is failing to find the module you reference in `clud.apps.catalogue` - I guess that import path isn't correct. You can try importing it from the shell, and if it doesn't work you need to specify a path that does depending on where your module is located.

I really appreciate your response.

What I did was to include the "apps/catalogue.__init__.py' in the get_core_apps

But I still don't know the implication of doing it this way but is working for now.

Also not sure if this is a bug in Django Oscar.

from oscar import get_core_apps

INSTALLED_APPS = [

'django.contrib.admin',

'django.contrib.auth',

'django.contrib.contenttypes',

'django.contrib.sessions',

'django.contrib.sites',

'django.contrib.messages',

'django.contrib.staticfiles',

'django.contrib.flatpages',

# 'clue.apps.my_products',

'elasticsearch5',

'debug_toolbar',

    'compressor',

    'widget_tweaks',

] + get_core_apps(['apps/catalogue.__init__.py'])

Try to add this line in __init__ file of your forked catalogue app.

default_app_config = 'clue.apps.catalogue.apps.CatalogueConfig'

I am not 100% sure, but think it's highly likely that the reason you're having to do this is because you're on Windows which handles file paths differently. Oscar doesn't officially support Windows, and I suspect you will run into more issues further down the line.

The dafault_app_config is automatically generated by Oscar.  It is in the catalogue app __init__.py file after running the oscar_fork_app command . 

Still getting the same outcome

Sincerely would love to contribute to seeing Windows being supported in Django Oscar.

How do we go about it please ?

Thanks for the help

The get_core_apps issue should have been resolved in Oscar 2 (currently in beta), because it was removed completely and we now rely on Django's app framework.

I am sure there are still other issues with some of Oscar's dependencies - don't know exactly which ones because we don't develop with Windows, and there haven't been many bug reports. I guess a good place to start would be to identify where things don't work on Windows, and create an issue on Github that describes where the problems are. It would then need someone to spend the time trying to find solutions for them.

More than happy to facilitate code review for any fixes you are able to provide.

Thanks,

Samir
