single table inheritance

[braver]

Is there a way to do single table inheritance in django?  E.g., I have
this part of a classical CD model:

# order is preserved here,
# but changes for derived classes => so we invert it for them!

class Person(meta.Model):
    middle_name = meta.TextField(null=True)
    last_name   = meta.TextField()
    first_name  = meta.TextField()

class Composer(Person):
    pass

class Conductor(Person):
    pass

class Soloist(Person):
    pass

Here's the SQL generated by django:

CREATE TABLE "cd_persons" (
    "id" integer NOT NULL PRIMARY KEY,
    "middle_name" text NULL,
    "last_name" text NOT NULL,
    "first_name" text NOT NULL
);

CREATE TABLE "cd_composers" (
    "id" integer NOT NULL PRIMARY KEY,
    "first_name" text NOT NULL,
    "last_name" text NOT NULL,
    "middle_name" text NULL
...

-- notice that the order of columns for Person corresponds to
cd_persons, but for the derived classes it's backwards!  Thus, I
inverted it in Person -- which is, in fact, abstract in C++ sense, I'm
only going to use Composer/Conductor/Soloist.  The SQL generator
appears broken for the order of the derived classes, or I'm not
supposed to do such things in a model?

Rails has "single table inheritance" in the sense you can put all
attributes into one table, and superimpose all classes on it, with an
extra "type" column as the discriminant/class tag.  Any such thing in
django?
