Hey! Just started working with Pylons in conjunction with SQLAlchemy, and my model looks something like this:

from sqlalchemy import Column
from sqlalchemy.types import Integer, String

from helloworld.model.meta import Base

class Person(Base):
    __tablename__ = "person"

    id = Column(Integer, primary_key=True)
    name = Column(String(100))
    email = Column(String(100))

    def __init__(self, name='', email=''):
        self.name = name
        self.email = email

    def __repr__(self):
        return "<Person('%s')" % self.name

To avoid sqlite reusing id's that might have been deleted, I want to add AUTOINCREMENT to the column "id". I've looked through the documentation for sqlalchemy and saw that the sqlite_autoincrement can be issued. An example where this attribute is given can be found here.

sqlite_autoincrement seems though to be issued when creating the table itself, and I just wondered how it can be supplied when using a declarative style of the model such as mine.
