Django - How to rename a model field using South?
django, django-models, django-south, python
Solution
You can use the `db.rename_column` function.
class Migration:
def forwards(self, orm):
# Rename 'name' field to 'full_name'
db.rename_column('app_foo', 'name', 'full_name')
def backwards(self, orm):
# Rename 'full_name' field to 'name'
db.rename_column('app_foo', 'full_name', 'name')
The first argument of `db.rename_column` is the table name, so it's important to remember how Django creates table names:
Django automatically derives the name of the database table from the name of your model class and the app that contains it. A model's database table name is constructed by joining the model's "app label" -- the name you used in manage.py startapp -- to the model's class name, with an underscore between them.
In the case where you have a multi-worded, camel-cased model name, such as ProjectItem, the table name will be `app_projectitem` (i.e., an underscore will not be inserted between `project` and `item` even though they are camel-cased).
Problem
I would like to change a name of specific fields in a model: ``` class Foo(models.Model): name = models.CharField() rel = models.ForeignKey(Bar) ``` should change to: ``` class Foo(models.Model): full_name = models.CharField() odd_relation = models.ForeignKey(Bar) ``` What's the easiest way to do this using South?
