I'm of the same opinion. Given the db abstraction that sqlobject offers I'm not sure I want to handle a too detailed exception hierarchy if any at all. Most of the time if I know it's a DatabaseError it will be enough to make a decision. This is why I said that catching all backend's specific errors and raising a DatabaseError will do the job as a starter, then specific exceptions can be added later as need arises (if such a need arises that is). > > That is true, but in the end do you prefer a solution that covers 60% > > of the usage cases out there right now or do you prefer to wait until > > someone will implement the perfect 100% complete solution somewhere > > in the unknown future? > > even thought handling specific db exceptions goes agains the db > abstraction layer of SQLObject I think the same here. A generic exception should do. The any other exception I can think of the moment as being useful would be an IntegrityError that says that the record you are trying to insert is a duplicate one (the uniqueness of some column is not satisfied). > I think it's better to have 100% then > 60% lots of errors could be swallow by the generic exception. I think the meaning of 60% was not 60% functionality, but 60% coverage of user needs. -- Dan ------------------------------------------------------- All the advantages of Linux Managed Hosting--Without the Cost and Risk!
