Hi,
I'm using Django 1.0.2, psycopg2 and PgSQL 8.3 on Ubuntu...
I've created a models.py with the following structure to represent a
"party model". The target for this is a simple CRM system.
Structure:
class Party(models.Model):
class Meta:
abstract = True
class Organisation(Party):
name = models.CharField(max_length=100)
class Person(Party):
first_name = models.CharField(max_length=50)
last_name = models.CharField(max_length=50)
This generates two tables (product_organisation + product_person) when
I run syncdb. According to This Week In Django [1], it states that
the model would be flattened into a single table inheritance model [2]
but it doesn't do this.
>From experience with other ORM platforms (nHibernate, custom built),
I'd expect this to flatten out to a table with approximately the
structure:
create table party (
party_id bigserial,
type char(1), -- p = party ... o = organisation
first_name character varying(50),
last_name character varying(50),
name character varying(50),
...
)
Is there something I am missing here?
Many Thanks,
Chris Smith
