Rails中STI的RESTful routes问题

POSTED AT: 2010-06-10 09:14:44 UTC | POSTED IN: Ruby/Rails | 4 COMMENTS

不解释，你是知道STI的——single table inheritance，我们看下问题是什么

现在有两个Model：Asset和Image

class Asset < ActiveRecord::Base; end
class Image < Asset; end

我们定义了这样一个RESTful routes

resources :assets

然后在我们的AssetsController里面

class AssetsController < ApplicationController
  def create
    @asset = Asset.new params[:asset]
    @asset.save
    respond_with(@asset)
  end

  def update
    @asset.update_attributes params[:asset]
  end
end
