This helper to exposes a method for caching of view fragments. See ActionController::Caching::Fragments for usage instructions.
Methods
Public Instance methods
A method for caching fragments of a view rather than an entire action or page. This technique is useful caching pieces like menus, lists of news topics, static HTML fragments, and so on. This method takes a block that contains the content you wish to cache. See ActionController::Caching::Fragments for more information.
Examples
If you wanted to cache a navigation menu, you could do the following.
<% cache do %> <%= render :partial => "menu" %> <% end %>
You can also cache static content…
<% cache do %> <p>Hello users! Welcome to our website!</p> <% end %>
…and static content mixed with RHTML content.
<% cache do %> Topics: <%= render :partial => "topics", :collection => @topic_list %> <i>Topics listed alphabetically</i> <% end %>
