Table-less model as base class?

[Eric Walstad]

Hi all,

I'd like to make a base class for my model classes that defines some
fields but doesn't result in a table in the database.  If my base class
is derived from meta.Model, then django makes a table for it in the
database.

Is it possible to do what I want, move common fields to a super class,
without generating a table for that super class?

Thanks,

Eric.

contrived example follows (I don't want the 'experiment_mybaseclasss'
table created):

experiment/models/experiment.py:
from django.core import meta
class myBaseClass(meta.Model):
    created_on = meta.DateTimeField(auto_now_add=True)
    modified_on = meta.DateTimeField(auto_now=True)
class myDerivedClass(myBaseClass):
    name = meta.CharField(maxlength=25)
    class META:
       module_name = 'my_derived_class'


$ django-admin.py sql experiment
BEGIN;
CREATE TABLE experiment_mybaseclasss (
    id serial NOT NULL PRIMARY KEY,
    created_on timestamp with time zone NOT NULL,
    modified_on timestamp with time zone NOT NULL
);
CREATE TABLE experiment_my_derived_class (
    id serial NOT NULL PRIMARY KEY,
    modified_on timestamp with time zone NOT NULL,
    created_on timestamp with time zone NOT NULL,
    name varchar(25) NOT NULL
);
COMMIT;
