With this change, - only the methods present in this whitelist will be delegated. - - The whitelist contains: - - #&, #+, #[], #all?, #collect, #detect, #each, #each_cons, #each_with_index, - #flat_map, #group_by, #include?, #length, #map, #none?, :one?, #reverse, #sample, - #second, #sort, #sort_by, #to_ary, #to_set, #to_xml, #to_yaml - - To use any other method, instead first call `#to_a` on the association. - - *Lauro Caetano* - * Use the right column to type cast grouped calculations with custom expressions.
