Hi All,
I'm wondering if there's a reason why Index doesn't play the sames that
ColumnCollectionConstraint does to allow columns names instead of column
objects to be parsed?
Why? Well, 'cos I'd like to do:
from sqlalchemy import *
metadata = MetaData()
mytable = Table('user', metadata,
Column('id', Integer, primary_key=True),
Column('name', String(40)),
UniqueConstraint('name'),
Index('test','id','name')
)
Er, okay, so why don't you just do:
mytable = Table('user', metadata,
Column('id', Integer, primary_key=True),
Column('name', String(40)),
UniqueConstraint('name'),
)
Index('test',mytable.c.id,mytzable.c.name)
Okay, I lied, I'm evil, what I really want to do is:
class Temporal(object):
id = Column(Integer, primary_key=True)
ref = Column(Integer ,index=True)
value_from = Column(DateTime, nullable=False)
value_to = Column(DateTime, nullable=True)
__table_args__ = (
Index('range','value_from','value_to'),
)
...and then use that mixin all over the place ;-)
I'm happy to do the work, provided there's no reason why this would be
insane / extremely hard to implement...
Chris
