I have some perfectly functional code which uses Class::DBI, but I find it a bother to maintain because fields are added to the database with some frequency.

I decided to try Class::DBI::Loader but have run in to a problem with transactions. When I was using Class::DBI, I simply defined a routine do_transaction() as suggested in the documentation, and this was inherited by all my table classes. However, with Class::DBI::Loader, the table classes are automatically created and don't inherit my code.

I solved this by creating a second package in the file, which contained the do_transaction() routine, and describing it as an additional_base_class. This seems to work, but I'm not sure if it was the best way to handle the problem, so I hope that someone with experience using Class::DBI::Loader could tell me how this is usually addressed. The documentation for Class::DBI::Loader is a bit on the skimpy side.

Thank you for your advice.
