Description

I'm unsure as to how Django is implementing South internally, but one thing that has always caused me pain is when I need to create myself a SubClass of Charfield and suddenly require to redefine all of the south migration profile. It would be better to be able to point to your parent class for the migration profile.

Example of desired ability:

class CharField2(CharField):
    
    .........
    .........

    class Meta:
        migration = super(CharField, self)._meta.migration

django.db.migrations is not just South pulled in. It's actually a rewrite of the entire concept to make it better.

Fields now require a deconstruct method to be used in migrations. As this is a simple method, it is automatically transferred onto subclasses. See the release notes for the current skeleton docs: ​https://docs.djangoproject.com/en/dev/releases/1.7/#new-method-on-field-subclasses
