I'm trying to deploy a django app that uses nested_inline on a heroku instance. Everything works great locally, but I'm getting an error on the heroku server during collectstatic.
I followed the heroku guide to getting a minimal django setup working. Then I added "django-nested-inline" to my requirements.txt, added 'nested_inline' to the end of my INSTALLED_APPS, and "from nested_inline.admin import NestedModelAdmin, NestedStackedInline" to my admin.py.
Everything still works perfectly locally, with no issues. But when I push to heroku "git push heroku master", I get the following error:
$ git push heroku master

As it says, the forms-nested.css file references images like nav-bg.gif, that don't appear to exist anywhere as far as I can tell. But this doesn't stop django and nested_inline from working perfectly fine locally. I'm not sure why it's breaking on heroku?
