sqlite WITHOUT ROWID with (flask-)sqlalchemy

model.py

import flask_sqlalchemy
from sqlalchemy import schema
from sqlalchemy.ext.compiler import compiles

db = flask_sqlalchemy.SQLAlchemy()


class Tag(db.Model):
    __table_args__ = {'info': {'without_rowid': True}}
    text = db.Column(db.String, primary_key=True)


@compiles(schema.CreateTable)
def compile(element, compiler, **kw):
    text = compiler.visit_create_table(element, **kw)
    if element.element.info.get('without_rowid'):
        text = text.rstrip() + ' WITHOUT ROWID\n\n'
    return text

Wonderful. Thank you @chaoflow !
