Hi, Allen!
You can use something like this (yeah, I know that it isn't
declarative in any way):
class Node(Base):
__tablename__ = 'node'
id = Column(Integer, primary_key=True)

I am using SQLAlchemy's Declarative Base to fully define and create my

For instance, there is a simple class/table Records, and I would like

If you are open to non RDBMS solution, sounds like what you need is message

I've attached a proof of concept for how I've approached the homegrown

If you have mapper definitions separate from classes, theres nothing
stopping you from adding attributes to the class over there, i.e.
mapper(MyClass, mytable)
MyClass.foo = some_validation_decorator(MyClass.foo)
Personally I wouldn't bother (then again I use declarative for everything

OK, never mind... I solved it.
The default = random.randrange(1000,1) code was happily taking the
static return value. Duh.
I changed it to:
default = lambda: random.Random().randrange(2000,8000)
I dunno if the extra Random() is needed, but it can't hurt, right?
On Jun 21, 4:32 pm,
default = lambda: random.randrange(1000,1)
Seems we crossed in the interwebs.. :)
Is it safe to do this, or do you need to do default = lambda:
random.Random()randrange(1000,1) ?
I ask since I have several tables that this needs to be applied to.
Thank you
3) Can this relation's objects be made read-only? That is:
u.room = new_room would work, but this would not: u.room.name =
'kitchen'
To clarify the question:
Can this objects seen via this relation be made read-only? That is:
u.room = a_room
u.room = a_new_room
...would work fine.
And
you can, you can use a validator that rejects all changes, or if
you're
brave you can create a custom __setattribute__ method that brokers all
attribute setter access. the former is in the SQLA mapping docs the
latter is part of Python.
Thank you. Interesting seems a bit of a round
