Question

I’m having a problem when using django custom commands on Heroku.
On my local machine, the custom command appears in help if I run ./manage.py help and running ./manage.py deletedphotos runs it too.
All the init.py files are there and the settings are also correct, i.e. there are not major config differences between my local and Heroku instances.

Now, when I put it on Heroku, it does not show up. All my other non-default commands are there: ping_google that comes from installing sitemap.xml support and commands for south migrations. But for some reason, my self written commands do not show up.

I’ve also sent a support request to Heroku, but haven’t heard back from them in a few days, so I thought I’d post here as well, maybe someone has had any similar problems.

The deletedphotos.py file contents are pretty much like this if that matters anything:

from django.core.management.base import BaseCommand, CommandError
from foo.app.models import *

class Command(BaseCommand):
    help = 'Delete photos from S3'

    def handle(self, *args, **options):
        deleted_photos = Photo.objects.filter(deleted=True).exclude(large='', small='', thumb='')
        self.stdout.write('Found %s photos\n' % str(len(deleted_photos)))

I’ve tried checking all the correct python paths etc, but not 100% if I’m not missing something obvious.

I was actually able to find a solution. The INSTALLED_APPS had my local app referenced, but for some reason it was not working as intended.

My app is in: /name/appname/ and having ‘name.appname’ in INSTALLED_APPS was working fine in local setup.

Yet, on Heroku, I had to change the reference to just ‘appname’ in INSTALLED_APPS and all started working magically.
