Django 1.7 introduced Migrations so now you don’t even need to install extra package to manage your migrations.

To rename your model you need to create empty migration first:

$ manage.py makemigrations <app_name> --empty

Then you need to edit your migration’s code like this:

from django.db import models, migrations

class Migration(migrations.Migration):

dependencies = [
    ('yourapp', 'XXXX_your_previous_migration'),
]

operations = [
    migrations.RenameField(
        model_name="Foo",
        old_name="name",
        new_name="full_name"
    ),
    migrations.RenameField(
        model_name="Foo",
        old_name="rel",
        new_name="odd_relation"
    ),
]

And after that you need to run:

$ manage.py migrate <app_name>
