Shared Model Methods

Hi all,

I just have a question about shared model methods. I have a method that will be used for quite a few models in my application (once I've cleaned it up a bit). Where can I place shared model methods? I know that controllers can use helpers or even the application_controller. But, what do models use for a shared mechanism? Is it config/initialize?

Yes, just use Ruby modules.

module SharedMethods

  def list     # ...   end end

And in your model,

class MyModel < ActiveRecord::Base

extend SharedMethods

end

Does this help?

Thanks a lot Jeff - yeah that's what I'm looking for. Does the ruby module have to belong in a certain place in my project to be usable by other models?

I figured it out. I actually made it simpler for me since I will be using a lot of methods (duplicate) for 37 different models.

I just created a plugin..

script/generate plugin template_searches

init.rb added..

ActiveRecord::Base.send :include, TemplateSearches

template_searches.rb added..

module TemplateSearches   def self.included(base)     base.extend(ClassMethods)   end

  module ClassMethods

  My Methods...

  end end

Removed the duplicate code and restarted and all is working well.
