But since the commit #12977, it doesn't work because when this is done, (in the {{{__new__}}} method of the Transmeta metaclass), the field has no model yet, and then an exception is raised in {{{__setstate__}}} at ligne 146 of [http://code.djangoproject.com/changeset/12977/django/trunk/django/db/models/fields/__init__.py db/models/fields/__init__.py] Is it a bad way of doing it in django-transmeta ?" closed Database layer (models, ORM) 1.2-beta duplicate Unreviewed 0 0 0 0 0 0
