python - Abstract inheritance from models in third party Django packages -

to abstract model inheritance in django, put

class meta:     abstract = true 

in parent model. mean impossible abstractly inherit model not have meta statement? specifically, not possible abstractly inherit model in existing model in third party package (unless change model)?

here example clarify asking. let's there django package called djangofoo i've installed in project's installed_apps. in djangofoo.models, let's have

from django.db import models  class person(models.model):     first_name = models.charfield(max_length=10)     last_name = models.charfield(max_length=25) 

i sub-class person in 1 own apps follows

from djangofoo.models import person  class myperson(person):     middle_initial = models.charfield(max_length=1) 

however, concrete inheritance. possible abstract inheritance? here's fictitious example of kind of magic looking for:

from djangofoo.models import person  abstractperson = abstractify(person)  class myperson(abstractperson):     middle_initial = models.charfield(max_length=1) 

of course change person model definition in djangofoo.models add appropriate abstract = true statement, preferable not have obvious reasons.
