ruby-on-rails-3 – 如何从Rails 3中的模型进行路由和渲染(调度)

概述我想从模型中调度(路由和渲染). (我只关心GET请求,我忽略了Accept：headers,所以我只看PATH_INFO.) # app/models/response.rbclass Response < ActiveRecord::Base # col :path_info # col :app_version # col :body, :type => :text de 我想从模型中调度(路由和渲染). (我只关心GET请求,我忽略了Accept：headers,所以我只看PATH_INFO.)

# app/models/response.rbclass Response < ActiveRecord::Base  # col :path_info  # col :app_version  # col :body,:type => :text  def set_body    params = Rails.application.routes.recognize_path(path_info,:method => :get)    controller = "#{params[:controller].camelcase}Controller".constantize.new    controller.action_name = params[:action]    controller.request = Actiondispatch::Request.new('rack.input' => [])    controller.request.path_parameters = params.with_indifferent_access    controller.request.format = params[:format] || 'HTML'    controller.response = Actiondispatch::Response.new    controller.send params[:action]    self.body = controller.response.body  endend

上面的代码有效,但感觉很笨拙.什么是正确的方法呢？我想象Yehuda Katz会告诉我类似的东西：

def set_body  # [...]  app = "#{params[:controller].camelcase}Controller".constantize.action(params[:action])  app.process params  self.body = app.response.bodyend

FWIW这是我的路线文件：

# config/routes.rbMyApp::Application.routes.draw do  resources :products                                       # GET /products.Json?merchant_ID=foobar  match '/:ID(.:format)' => 'contents#show',:via => 'get'  # GET /examples  root :to => 'contents#index',:via => 'get'               # GET /end

另见：Rails 3 request dispatch cycle

解决方法 它实际上比那更容易：

session = Actiondispatch::Integration::Session.new(Rails.application)session.get(path_info)self.body = session.response.body
