Example 1: how to create migrations in django
//to create migration files
python manage.py makemigrations
//to migrate migration files
python manage.py migrate
Example 2: 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
