[Rails] update_attrbutes without saving?

[Rubén Gil]

Hello all,

Is there a method for updating all the attributes from a hash without
saving to the database? (the counterpart of update_attributes but
without saving).

What I want to do is:

person = Person.find(params[:id])
person.update_without_saving(params[:person]) #update the in-memory
object.
# Process person object
.......
person.save

I know that when you are creating a new object, you can use Person.new
(updates in memory object) or Person.create (updates and saves to the
database), but don't know if the second option (apart from
update_attributes that saves to the database) exist when updating.

Thanks in advance,

Ruben
