It does :) Read up on the "get_set_on_save" variants of the methods created for the various relationship types. In this case, a one-to-one relationship, the default automatically created method types: http://search.cpan.org/dist/Rose-DB-Object/lib/Rose/DB/Object/Metadata/Relationship/OneToOne.pm#default_auto_method_types are "get_set_on_save" and "delete_on_save". Looking at the method map: http://search.cpan.org/dist/Rose-DB-Object/lib/Rose/DB/Object/Metadata/Relationship/OneToOne.pm#METHOD_MAP shows that methods of the "get_set_on_save" method type re created by Rose::DB::Object::MakeMethods::Generic, specifically its "object_by_key" method maker, using the interface "get_set_on_save" http://search.cpan.org/dist/Rose-DB-Object/lib/Rose/DB/Object/MakeMethods/Generic.pm#object_by_key Reading the documentation for the "get_set_on_save" interface reveals the details of the method behavior. An excerpt: "The object will be saved into the database when the "parent" object is saved." And there you have it :) I know it's quite a trip through the docs (there are links to click on, at least) but modular architecture tends to lead to modular documentation. -John ------------------------------------------------------------------------- Using Tomcat but need to do more?
