419	Create meta.AbstractModel	Adrian Holovaty	Adrian Holovaty	"{{{
#!python

class BaseModel(meta.Model):
    foo = meta.CharField(maxlength=200)

class FirstChild(BaseModel):
    bar = meta.CharField(maxlength=10)

class SecondChild(BaseModel):
    bar = meta.CharField(maxlength=10)
}}}

In this example, {{{BaseModel}}} only exists as an ""abstract class"" -- its only purpose is to be extended. We don't want to install SQL for it, and we don't want it to be available via the API. So we could introduce a {{{meta.AbstractModel}}} for models that serve this purpose."	enhancement	closed	Metasystem		enhancement	duplicate		eric@…	Unreviewed	0	0	0	0	0	0
