Rails does this so effortlessly I couldn't believe TG 1.1 doesn't.
To accomplish this I have the following as the base of all my DB model
objects:
<code>
# the identity model
class DBObject(object):
def __init__(self):
object.__init__(self)
def get_values(self):
values = {}
for a in self._sa_class_manager:
try:
values[a] = self.__getattribute__(a)
except:
pass
return values
</code>
If you ensure that your form widget fields have the same name as your
DB columns you can then populate the form quickly with something like:
<code>
user = session.query(User).filter(User.user_id == 1).first()
form = forms.edit_user.form
return {
"form" : form,
"values" : user.get_values()
}
</code>
Have I reinvented the wheel ? Does TG already have this kind of
thing ?

Also: Form Inheritance and field ordering.
If I inherit form B from form A and if form B adds additional fields
(such as may be hidden from a normal user but visible to an admin
user) is it possible to affect the ordering of these field when
displayed ? Current ordering seems to be strictly declaration order.
