Question

我创建了一个新的控制器并添加了一个新动作（ my_new_action ）。对于routes.rb，我添加了此操作的路由，但是当我在URL浏览器中设置地址 localhost：3000 / users / my_new_action 时，我将收到主题中的错误。< / p>

class UsersController < ApplicationController
  # ....

  def my_new_action  
  end
end

有人可以帮助我，如何解决？

由于

修改

  resources :users do
    collection do
      get 'my_new_action'
    end
  end

EDIT2 这是终端的确切输出：

    Started GET "/users/my_new_action" for 127.0.0.1 at Sat Nov 26 13:55:50 +0100 2011

Answer 1

标题具有误导性，您放置<controller>因为您可能看到User，但它很可能是指您正在尝试构建或使用的模型。因为你没有粘贴更多的代码，所以我不能确切地说出问题的位置，而是寻找对你在代码中使用的id的引用 - 这很可能是null。

Answer 2

您收到错误是因为路由无效，代码显示的是url / users / my_new_action正在尝试为默认的“show”找到'/ users / my_new_action'的用户ID动作。

我会将您提供的路线代码替换为类似的东西（请注意，这不是经过测试的代码）......

resources :users do
    match '/my_new_action', :controller => 'users', :action => 'my_new_action', :as => :mynewaction
end

Rails 3 - 找不到没有ID的<controller> </controller>
