timed_fragment_cache (without dogpile)¶ ↑

git clone [email protected]:weibel/timed_fragment_cache.git
in your vendors/plugin directory

or

script/plugin install [email protected]:weibel/timed_fragment_cache.git

In your controller

when_fragment_expired 'some_posts', 1.hour.from_now do
  @posts = Post.find( :all )
end

In your view

<%- cache 'some_posts' do -%>
  <%- @posts.each do |post| -%>
    <%= @post.title %>
  <%- end -%>
<%- end -%>

Or

<%- cache 'some_posts', 20.seconds.from_now do -%>
  <%- @posts.each do |post| -%>
    <%= @post.title %>
  <%- end -%>
<%- end -%>

Prevent cache dogpiling by using

<%- cache_without_dogpile 'some_posts', 20.seconds.from_now do -%>
  <%- @posts.each do |post| -%>
    <%= @post.title %>
  <%- end -%>
<%- end -%>
