Hi,
I am using SQLAlchemy 0.5rc4.
Is there a way to test if the values of an object are valid for
commiting? I tried something like:
try:
session.commit()
except:
notify the user
But the problem is, that if the commit fails and I change the non
valid value to a valid one the session will still not commit.
One other thing I'd like to know:
Is it possible to ask a mapped object information about the mapped
values like:
- what data type is expected (int, str ...)
- what is the maximal length
- is it nullable
Regards,
Hinrich.
