Customize/modify Rails 3 resources routing

Question

I'm currently writing a rails app that has your regular resource like objects. However I would like to make my resources syncable. My web application uses web offline storage to cache results from the server (user's cannot modify data on server making syncing easier). When I fetch from the server, it returns a hash response like:

{
  :new => [...]
  :updated => [...]
  :deleted => [...]
}

This is all well and good until I want to have a regular fetch method that doesn't do any sort of syncing and simply return an array of models

Now my question is I want to create a method in my routes.rb file that sets up routes so that I have a route to synced_index and index. Ideally, I'd be able to do something like this:

synced_resources :plans

And then all of the regular resource routes would be created plus a few extra ones like synced_index. Any ideas on how to best do this?

Note: I do know that you can modify resources with do...end syntax but I'd like to abstract that out into a function since I'd have to do it to a lot of models.

You can easily add more verbs to a restful route:

resources :plans do
  get 'synced_index', on: :collection
end

Check the guides for more information on this.

If you have several routes that are similar to this, then sure, you can add a 'synced_resources' helper:

def synced_resources(*res)
  res.each do |r|
    resources(r) do
      get 'synced_index', on: :collection
    end
  end
end

Wrap above method in a module to be included in ActionDispatch::Routing::Mapper.

Ended up putting it in an initializer which is necessary since it needs to be executed before routes get drawn. Thanks!
