John,
I think my confusion was this:
I expected the accessor to be named the lowercase, plural version of the
class name:
My::DB::GMain is the class name, so I expected gmains. In practice, I
looked a the loader code and it is using the ACTUAL table name, so the class
is:
My::DB::GMain with manager class My::DB::GMain::Manager, and method
get_g_main. That works as expected now that I know what to expect.
