Hey Moritz,

Any methods you add in your Book schema class will be methods that act on a book row object ($self will be a row object).  Doing that is described here (but only wrt overloading methods, but the idea is the same for new methods) http://search.cpan.org/dist/DBIx-Class/lib/DBIx/Class/Manual/Cookbook.pod#OVERLOADING_METHODS

Hope that helps.  Not sure if that's what you were asking about, though.  Your question is a little vague.

Regards,
Byron
