资源说明：Abstract resource controller + generator for Rails
CrudGenerator
=============
A combination of a base controller class, and a generator. You use the CRUDController as the base class for your controllers (e.g. BooksController < CRUDController). You use the generators to generate the models / controllers, much like the scaffold generator and scaffold_resource generator. The views that get generated all follow the syntax of the new RESTful features built into Rails, and the conventions used by the SimplyHelpful plugin.
You don't have to move code anywhere, the CRUDController and helper hook themselves in automatically. There are various ways to override the behavior of the CRUDController without needing to replace the method by writing it directly in your controller.
INSTRUCTIONS
===============
Generates a CRUD-ready controller and model.
Example:
script/generate crud book
Will generate a Book model (and associated migration), a Books controller (which inherits from CRUDController), and some sample views.
This generator assumes the use Rails 1.2+, so don't forget to put something like:
map.resources :books
in your routes.rb.
EXAMPLES:
=============
These examples are taken from real applications.
For an XML API controller where we only wanted to allow :show and :index methods. This particular controller just delivers XML to HTTP requests from a Flash SWF running in the page. This examples shows the override for the model name and a way to block some of the default actions that would otherwise be available by inheritance.
class PlaylistApiController < CRUDController
undef :new, :create, :edit, :update, :destroy
model_class Playlist
end
This example shows overrides of some methods (including controller actions and the protected #build_model)
class ProductsController < CRUDController
def update
current_instance.product_images << @product_images if @product_images
super
end
protected
def build_model
product = super
returning product do
product.product_images << @product_images if @product_images
end
end
end
Requirements
============
* Rails 1.2+
* SimplyHelpful plugin (http://dev.rubyonrails.com/svn/rails/plugins/simply_helpful)
* AuthenticatedSystem from acts_as_authenticated or restful_authentication
