= Render Caching
Cache render calls in Rails controllers.
== Install
First install the gem.
gem install ryanb-render-caching --source=http://gems.github.com
Then specify it in your Rails config.
config.gem 'ryanb-render-caching', :lib => 'render_caching', :source => 'http://gems.github.com'
Rails 2.1 or later required.
== Usage
This gem adds the render_with_cache method to all controllers. Call
this inside of an action to cache the view.
def show
@user = User.find(params[:id])
render_with_cache
end
This will cache the full rendered contents into a key matching the URL
path (similar to action caching). You can change this key by simply
passing any parameter.
def show
@user = User.find(params[:id])
render_with_cache @user.cache_key
end
Cache key is a method supplied by Rails. This includes the updated_at
time which will give you an auto-expiring cache when the user record is
updated.
You can also supply a block to the render call which will only get
executed if there is no cache. Here is a good place to do any custom
render calls.
def show
@user = User.find(params[:id])
render_with_cache @user.cache_key do
render :layout => false
end
end
