Чем можно заменить «drop_receiving_element» для совместимости с Rails 3+?

html += drop_receiving_element "drop-#{issue.id.to_s}-#{column.status.id.to_s}",
                                       :url => { :action => "update", 
                                                 :where => column.status.id.to_s, 
                                                 :drop => issue.id.to_s,
                                                 :version => @version },
                                       :hoverclass => "hover",
                                       :before => "Element.hide(element)"
