Hi everyone! I need to declare a few unrelated classes (from a "business" perspective) that share some attributes/fields, so I thought I could use an abstract class to group these common attributes (note that just a few classes should have them, not every one)
This post http://groups.google.it/group/sqlalchemy/msg/d3de02f609a0bbd9?hl=it suggests to use mixins, but I can't get it to work, SQLA generates the tables without the common fields. I'm testing it with this script: >from sqlalchemy.ext.declarative import declarative_base >from sqlalchemy import Column, Integer, String >from sqlalchemy import create_engine > ># --- Tables definition >Base = declarative_base() > >class Abstract(object): > notes = Column(String) > >class Concrete(Base, Abstract): > __tablename__ = 'concrete' > id = Column(Integer, primary_key=True) ># --- > ># DB creation >engine = create_engine('sqlite:///:memory:', echo=True) >Base.metadata.create_all(engine) Here's the sql call: >CREATE TABLE concrete ( > id INTEGER NOT NULL, > PRIMARY KEY (id) >) What am I missing? Did I misunderstood how the mixin should be used? (I'm using SQLA 0.5rc4) Many thanks! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
