Question

Is there a way to edit an existing Django model class (adding/removing fields), and make the changes apply to previously created objects in the (SQLite) database?

For instance:

class Mod(models.Model):
    usrID = models.IntegerField(default=0)
    name = models.CharField(default="")

And in a later stage, after there are a large amounts of objects of named class instantiated, change to:

class Mod(models.Model):
    usrID = models.IntegerField(default=0)
    name = models.CharField(default="")
    description = models.TextField(default="")

Answer 1

Yes. Use a database migration tool, one of the most popular database migration for Django is South.
