Hey guys -
I forgot about the really obvious way to do this - class decorators:
from sqlalchemy import *
from sqlalchemy.orm import *
from sqlalchemy.ext.declarative import declarative_base
Base = declarative_base()
def common_columns(cls):
cls.created_at = Column(DateTime, default=func.now)
cls.udpated_at = Column(DateTime, default=func.now, onupdate=func.now)
return cls
@common_columns
class MyClass(Base):
__tablename__ = 'mytable'
id = Column(Integer, primary_key=True)
data = Column(String)
@common_columns
class MyOtherClass(Base):
__tablename__ = 'myothertable'
id = Column(Integer, primary_key=True)
data = Column(String)
engine = create_engine('sqlite://', echo=True)
Base.metadata.create_all(engine)
