Your models have changes that are not yet reflected in a migration, and so won't be applied. Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.
$ python manage.py makemigrations && python manage.py migrate $ git add --all $ git commit -m "fixed migrate error" $ git push heroku master $ heroku run python manage.py makemigrations $ heroku run python manage.py migrate --- Done ___
