Rename field using migrations in django 1.7

gistfile1.txt

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.

4.  Apply the migration  
$ python manage.py migrate myApp

2. Create an empty migration

It is a bit easier to create an automatic migration, and replace the RemoveField + AddField pair with one RenameField (or with RenameField + AlterField if needed).

operations = [ migrations.RenameField('MyModel', 'old_field_name', 'new_field_name'), ]
perfect!

I'm not sure when this feature is added to Django but just accidentally found Django 2.1.4 asks for renames when running makemigrations. At least in my case, which was location_state -> location_city.

@amirkarimi I found this doesn't always happen - I came here from a google search because I needed to change a migration that dropped the field and added the new one instead of renaming it.

HERO!!!

thanks!

Thankyou so much!

Great! Working !

Easier way I found:
1st: Is changing the model to the correct name you want.
2nd: Changing the file in migrations folder which usually looks like 0001_initial.py and changing the field name in the list to the correct field name you want also.
3rd: change the column name in the Database.

It's working to me. Thanks!!

💯. Thanks
