h1. Example

Example controller:


  

    class CommentsController < ApplicationController

      parent_resources :article, :document

      

      def new

        @parent = parent_object

        @comment = Comment.new

      end

      

      def create

      

        @parent = parent_object

        @comment = @parent.comments.build(params[:comment])

      

        if @comment.valid? and @comment.save

          redirect_to send("#{ parent_type }_url", @parent)

        else

          render :action => 'new'

        end

      end

    end
