module CacheHelper
|
|
# 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 %>
