ruby-on-rails - 简单的 redirect_to 显示路径不起作用

Question

我试图在资源创建后显示它。

路线.rb

  resources :eco_systems do
    member do
      get 'new'
      post 'create'
      get 'show'
    end
  end

eco_systems_controller.rb

class EcoSystemsController < ApplicationController
  def new
    @eco_system = EcoSystem.new
  end
  def create
    @eco_system = current_user.eco_systems.create(params[:eco_system])
    redirect_to eco_system_path(@eco_system.id)
  end
  def show

  end
end

当 redirect_to eco_system_path(@eco_system.id) 运行时，生成的 URL 是

http://localhost:3000/eco_systems/5

控制台输出:

Started GET "/eco_systems/5" for 127.0.0.1 at 2011-06-14 16:04:22 +1000
  Processing by EcoSystemsController#new as HTML
  Parameters: {"id"=>"5"}

但是加载的页面是新页面。为什么没有加载显示操作/ View ？

Answer 1

这是因为 show 操作是在 new 之后定义的，如果你运行 rake routes 你会看到

 eco_system GET    /eco_systems/:id(.:format)      {:action=>"new", :controller=>"eco_systems"}
            POST   /eco_systems/:id(.:format)      {:action=>"create", :controller=>"eco_systems"}
            GET    /eco_systems/:id(.:format)      {:action=>"show", :controller=>"eco_systems"}

当从顶部开始检查路由时，第一个 Action 被调用
