Static page caching for Action Pack (removed from core in Rails 4.0)
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install actionpack-page_caching
Page caching is an approach to caching where the entire action output of is stored as a HTML file that the web server can serve without going through Action Pack. This is the fastest way to cache your content as opposed to going dynamically through the process of generating the content. Unfortunately, this incredible speed-up is only available to stateless pages where all visitors are treated the same. Content management systems -- including weblogs and wikis -- have many pages that are a great fit for this approach, but account-based systems where people log in and manipulate their own data are often less likely candidates.
Specifying which actions to cache is done through the
caches_page class method:
class WeblogController < ActionController::Base caches_page :show, :new end
This will generate cache files such as
weblog/new.html, which match the URLs used that would normally trigger
dynamic page generation. Page caching works by configuring a web server to first
check for the existence of files on disk, and to serve them directly when found,
without passing the request through to Action Pack. This is much faster than
handling the full dynamic request in the usual way.
Expiration of the cache is handled by deleting the cached file, which results
in a lazy regeneration approach where the cache is not restored before another
hit is made against it. The API for doing so mimics the options from
class WeblogController < ActionController::Base def update List.update(params[:list][:id], params[:list]) expire_page action: 'show', id: params[:list][:id] redirect_to action: 'show', id: params[:list][:id] end end
Additionally, you can expire caches using Sweepers that act on changes in the model to determine when a cache is supposed to be expired.
