OK, if you are trying to select an object with the mapper, then you
want to select it again and insure it is fresh from the DB, then you
have to remove it from the identity map. Since you say the object
isnt even present in the identity map, that means it definitely wasnt
loaded by a mapper (unless you are clearing things out in between).
I guess you are dealing with a newly constructed object and just want
to reset its attributes ? Im not exactly sure what youre doing that
it would matter (maybe a simplified version of your previous code
would help me understand)...
anyway, if you have an object that is managed by a mapper, and you
want to remove the attribute history, just do :
objectstore.global_attributes.commit(obj)
or to roll back its attributes to what they were before modified:
objectstore.global_attributes.rollback(obj)
but show me what youre trying to do again, a little more simply, so i
can see what youre looking for.
