Module: ActionController::Components

Defined in:
lib/action_controller/components.rb

Overview

Components allows you to call other actions for their rendered response while execution another action. You can either delegate the entire response rendering or you can mix a partial response in with your other content.

class WeblogController < ActionController::Base
  # Performs a method and then lets hello_world output its render
  def delegate_action
    do_other_stuff_before_hello_world
    render_component :controller => "greeter",  :action => "hello_world", :params => { "person" => "david" }
  end
end

class GreeterController < ActionController::Base
  def hello_world
    render_text "#{@params['person']} says, Hello World!"
  end
end

The same can be done in a view to do a partial rendering:

Let's see a greeting: 
<%= render_component :controller => "greeter", :action => "hello_world" %>
