Module: Ardes::ResourcesController::Actions

standard CRUD actions, with html, js and xml responses, re-written to mnake best use of resources_cotroller. This helps if you‘re writing controllers that you want to share via mixin or inheritance.

This module is used as the actions for the controller by default, but you can change this behaviour:

  resources_controller_for :foos, :actions_include => false               # don't include any actions
  resources_controller_for :foos, :actions_include => Some::Other::Module # use this module instead

Why?

The idea is to decouple the model name from the action code.

Here‘s how:

finding and making new resources

Instead of this:

  @post = Post.find(params[:id])
  @post = Post.new
  @posts = Post.find(:all)

do this:

  self.resource = find_resource
  self.resource = new_resource
  self.resources = find_resources

referring to resources

Instead of this:

  format.xml { render :xml => @post }
  format.xml { render :xml => @posts }

do this:

  format.xml { render :xml => resource }
  format.xml { render :xml => resources }

urls

Instead of this:

  redirect_to posts_url
  redirect_to new_post_url

do this:

  redirect_to resources_url
  redirect_to new_resource_url
