To change a field name in django 1.7+ | |
1. Edit the field name in the model (but remember the old field name: you need it for step 3!) | |
2. Create an empty migration | |
$ python manage.py makemigrations --empty myApp | |
3. Edit the empty migration (it's in the migrations folder in your app folder, and will be the most recent migration) by adding | |
migrations.RenameField('MyModel', 'old_field_name', 'new_field_name'), | |
to the operations list. |
