Override destroy -- how to save it?

I would like to override the destroy method of my AR objects with
something like this:

module Restorable

  alias_method :really_destroy, :destroy

  def destroy
    self.destroyed = Date.today
    self.save(false)
    self
  end

  def restore
    self.destroyed = nil
    self.save(false)
    self
  end

end

Problem is that Restorable doesn't have a destroy method to
alias_method. Is there a way to get this sort of functionality? I
would like to avoid adding a new method (like delete) to save
confusion and so I don't have to go back and change my controllers.

Thanks,

Hi,

Problem is that Restorable doesn't have a destroy method to
alias_method. Is there a way to get this sort of functionality?

everytime a module is included as a mix-in, the method "included" of the module is called, and the class including the module is passed as a parameter, so you can practice any kind of ruby dynamic black magic over the original class, in your case an AR object. I'm pasting a small template you can use for yor mix-in

def self.included(parent_class)
    class << parent_class
      #everything you do here will be evaluated on the parent class content, so any method aliasing and/or overwriting should be done here
    end
  end

You might want to look at acts_as_paranoid:

http://ar-paranoid.rubyforge.org/

though I guess that doesn't give you a restore method....

Thanks for the reply. I'll extend a_a_paranoid to include a restore
method.

Thanks also to javier.
