isn't that exactly what you do with the 'proxy' attribute? see https://metacpan.org/module/DBIx::Class::Relationship::Base#attributes so in your User table, you would define the relationship like this: --8<------------------------------------------------------------------- __PACKAGE__->belongs_to( "user_type", "Your::Schema::Result::UserType", { user_type_id => "user_type_id" }, { proxy => { type => 'name', }, }, ); --8<------------------------------------------------------------------- not sure though about your other intentions with the dynamic columns class. patrick -- Patrick Meidl ........................ patr...@pantheon.at Vienna, Austria ...................... http://gplus.to/pmeidl _______________________________________________ List: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/dbix-class IRC: irc.perl.org#dbix-class SVN: http://dev.catalyst.perl.org/repos/bast/DBIx-Class/ Searchable Archive: http://www.grokbase.com/group/dbix-class@lists.scsys.co.uk
