Extend taggable-mixin to support different Tag models. Usage is pretty simple. Tag model is default in Taggable constructor but you can call it with different model like GHOPTaskType that inherits from Tag model. Both Taggable and Tag models have been updated and they don't use hardcoded Tag model anymore and instead use cls of class methods or self.__class__. In case of Taggable it's self.__tag_model.

from django.core.management.base import AppCommand

class Command(AppCommand):
    help = "Prints the CREATE TABLE, custom SQL and CREATE INDEX SQL statements for the given model module name(s)."

    output_transaction = True

    def handle_app(self, app, **options):
        from django.core.management.sql import sql_all
        return u'\n'.join(sql_all(app, self.style)).encode('utf-8')
