Override destroy -- how to save it?


#1

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.
