REST + Pagination + Caching

Hi all,

I want to have a RESTful resource (because I need to use atom_feed_builder).

For the sake of the exemple, let say I need : map.resources :news

I want to be able to list all the news in index action, paginate it (using will_paginate for example) and add cache to it each paginated page.

To add cache I need to have url like news/page/2, urls like news/?page=2 can't be cached page by rails.

So any idea to solve this problem ?

Thanks.

The answer was "use fragment caching"

# Controller def index     unless read_fragment({:page => params[:page] || 1}) # Add the page param to the cache naming       @news = News.paginate :all, :page => params[:page]     end end

# View <% cache ({:page => params[:page] || 1}) do %>      ... All of the html to display the posts ... <% end %>
