Used to transform value from metadata to data. Accepts Symbols, which it will send against context. Accepts Procs, which it will execute with controller and context. Both Symbols and Procs will be passed arguments of this method. Also accepts Hash of these Symbols or Procs. If any other value will be passed, returns original value.

Parameters:

  • context (Object) —

    Context to resolve parameter, which is usually target or notificable model

  • thing (Symbol, Proc, Hash, Object) —
