prevents the use of attributes that match core functions

I'm creating a resource that has a method attribute, but due to the way it works now:

  define_method attr do
    @model.public_send(options[:delegate] ? options[:delegate].to_sym : attr)
  end unless method_defined?(attr)

It fails to work for me. I know method is a core ruby function, but it's also the word used to describe HTTP's GET and PUT.

One option is to simply drop the unless. Allow rewriting, but warn.

Another option is to provide an in and out type option. Currently I would describe delegate as the in, where it describes how to take in the data, and I would provide a key option as the out functionality (what the resulting key will look like).

Inizia dalla definizione dell’attributo resource mostrata nell’issue e analizza come method_defined? bloccava gli accessor generati per nomi come method. Decidi se le collisioni debbano essere sovrascritte con un avviso o mappate con una chiave di output esplicita, quindi aggiungi una copertura di regressione per il comportamento scelto.
