In my application I'd like db related errors that are encountered when using mapped classes to have better exceptions that make more sense in the context of my program. Where is the best place to put this stuff?
For example, say I have a table with a single primary_key column and I have a class MyData mapped to that table. If someone were to try to make and flush a MyData(someDuplicateEntry) instance they'd get an ugly sqlalchemy exception. I'd rather they get, say, an AlreadyExistsException() or something to that effect. Now, I can wrap each flush with a try/except block, or have the __init__ method of the class do a check during instantiation, but I'm wondering if there is some better way to do it. Perhaps a way to map SqlerrorA to throw ExceptionA and SqlerrorB to throw ExceptionB.
