[Answer]-Model Inheritance with Django

You do not have to define the definition in your ActionType because it will be inherited already from your ControlVocabulary

You can check it already as follows:

x = ActionType.objects.all()
x[0].__dict__

Other way to check is by looking at the fields of you model in the database

EDIT:

Tried replicating the error:

models:

class ControlVocabulary(models.Model):
    definition = models.TextField()
    term = models.CharField(primary_key=True, max_length=255)
    class Meta:
        abstract = True
class ActionType(ControlVocabulary):
    #definition = ControlVocabulary.definition # <-- Error
    class Meta:
        verbose_name='Action'

and in the shell:

Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from testapp.models import *
>>> x = ActionType.objects.all()
>>> x
[]
>>> y = ActionType(definition='my definition')
>>> y.save()
>>> ActionType.objects.all()
[<ActionType: ActionType object>]
