I recently added a model to my app (UserProfile) and when I pushed the changes to Heroku, I think I accidentally ran heroku run python manage.py makemigrations. Now when I try to run heroku run python manage.py migrate I get the error below

  Your models have changes that are not yet reflected in a migration, and so won't be applied.

How do I fix this? Please help!

You need to first create the migrations locally, add them to your repository, commit the files with the new migrations and then push to heroku.

The sequence is something like this:

1. (add/modify some someapp/models.py)
2. python manage.py makemigrations someapp
3. python manage.py migrate
4. git add someapp/migrations/*.py (to add the new migration file)
5. git commit -m "added migration for app someapp"
6. git push heroku
7. heroku run python manage.py migrate

Configuring Django Apps for Heroku, First, and most importantly, Heroku web applications require a Procfile .

Deploying Python and Django Apps on Heroku, Heroku automatically identifies your app as a Python app if any of the following files are present in its root directory: requirements.txt; setup.py  Heroku recommends the use of WhiteNoise (a Django package) to serve static files in production, since Django does not support serving static files in production, by default. Add whitenoise middleware at the top of the middleware list in settings.py

It sounds like you ran makemigrations after you made changes to your model but before you had an initial migration file. Try to revert your app to the state it was before you added the new model and run makemigrations again to create the initial migration. Then add your updates back in and run makemigrations once more. This will create a second migration from your initial data structure to the new updated one. Then try your deployment.

Comments
  • First - thanks a bunch for attempting to help me. Now, my local environment is up to date and working as I expect. When I run git status, it says my files are up to date and when I run git push heroku master it says Everything up-to-date. Yet, when I run heroku run python manage.py migrate I get the error "Your models have changes that are not yet reflected in a migration" as I described. Any other ideas or suggestions for me to troubleshoot?
  • It seems then that your repositories are out of sync; do you have any untracked files?
  • If you're referring to my .gitignore file, it is a copy of this github.com/github/gitignore/blob/master/Python.gitignore with nothing extra
  • I deleted my app inside heroku, but when I added it back I still get the same error! Any chance I could hire you to help me get this figured out?
  • What do you get with this: git ls-files . --exclude-standard --others ?
  • Your last sentence solved me problem!!! Thanks
  • Thanks. allauth.socialaccount was giving me the error. I ended up dropping it and everything migrated fine after that. Other people have reported the error here github.com/pennersr/django-allauth/issues/836 Hoping they come up with a patch.
