<%doc> =head2 maybe_link_view C takes something returned from the database - either some ordinary data, or an object in a related class expanded by a has-a relationship. If it is an object, it constructs a link to the view command for that object. Otherwise, it just displays the data. This tests whether or not the returned value is an object, and if so, creates a link to a page viewing that object; if not, it just displays the text as normal. The object is linked using its stringified name; by default this calls the C method, or returns the object's ID if there is no C method or other stringification method defined. <%args> $object % if ( UNIVERSAL::isa( $object, 'Maypole::Model::Base' ) ) { <& link, table => $object->table, command => "view", additional => $object->id, label => $object &> % } else { <% $object %> % }
