Hello, everyone,
Let's say I have a class like this:
Class Foo(...):
id = Column('id', Sequence('id_seq'), primary_key=True)
color = Column(...)
size = Column(...)
How do I instantiate one of these Foo objects without specifying an id for it
(letting it come from the id_seq sequence) and have immediate access to its
'id' attribute value before I commit the session? In other words, what I'd like
to do is this:
new_foo = Foo(color='blue', size='large') # do not specify id
print(new_foo.id) # at this point, new_foo is a Foo, but new_foo.id is None!
I've tried putting FetchedValue() on the Foo.id column, and I've tried flushing
the session before accessing new_foo.id, but neither of those things seem to
work.
Thanks for your time and reply,
Mike
