Question

I just deployed my first django app to the Heroku platform. I basically followed this tutorial, just that instead of creating a dummy django-admin.py startproject hellodjango . django app, I used my app that currently works on my Windows PC. When deploying the app and running the server on heroku I get a No module named theme.urls.

Here is the traceback. Any ideas?

Environment:

Answer 1

So I found that the error was that heroku created the app in a folder named ‘app’ instead of ‘theme’. I tried renaming the app via the heroku CLI using

heroku apps:rename theme

but for some reason I cant figure out still, it gave a You do not have access to appname error. So instead I just went and changed every part of my code that had theme.foo to app.foo. And it worked.
