Javascript 我的控制器操作的路由问题

我的用户控制器中有一个填充表单方法。。问题是，当我在视图中填写文本字段并单击它时，我想在我的控制器中显示，但在我的用户控制器中没有显示操作。任何帮助都将不胜感激

这是我的错误

Started GET "/user/populate_form&emp_id=BILL" for 127.0.0.1 at 2015-03-23 17:39:17 -0400

AbstractController::ActionNotFound (The action 'show' could not be found for UserController):

这是我的用户控制器

class UserController < ApplicationController


def populate_form
  @visual = Visual.find_by_id(params[:emp_id])
     render :json => {

        :emp_first_name => @emp_first_name
     }
  end
end

def show
  @visual = Visual.find_by_id(params[:emp_id])
     render :json => {

         :emp_first_name => @emp_first_name
     }
  end
end

这是我的路线

Rails.application.routes.draw do


 devise_for :users, controllers: { sessions: 'sessions' }

 root to: 'entry#index'

 resources :entry do
 end

 resources :user do
    collection do
      get :populate_form
    end
  end

 # Routes for API calls only.

 namespace :api do

 end
end

这是我在搜索路线时得到的额外费用

                     DELETE   /user/:id(.:format)            user#destroy
                     GET|POST /entry(.:format)               entry#index

现在我明白了，它没有拾取我文本框中的内容，而且它是空的

Started GET "/user/populate_form&emp_id=BILL" for 127.0.0.1 at 2015-03-23 17:52:29 -0400
Processing by UserController#show as JSON
Parameters: {"id"=>"populate_form&emp_id=BILL"}
Visual Load (2.2ms)  SELECT  "EMPLOYEE".* FROM "EMPLOYEE"  WHERE "EMPLOYEE"."ID" IS NULL AND ROWNUM <= 1

这可能有点让人困惑，但让我们一起来看看吧

您有如下配置的路由：

resources :user do
  collection do
    get :populate_form
  end
end

您一直希望访问某个URL，在controller-populate_表单中调用适当的操作，但出于某种原因，它试图将您的请求路由到显示

让我们检查一下您的URL：

/user/populate_form&emp_id=BILL

这会导致整个请求落入被识别为以下内容的路径：

user GET /user/:id

对应于表演动作。整个字符串populate_form&emp_id=BILL在show动作中落入参数[：id]。为什么它没有采取适当的行动？我们一直期待着能达成共识

尝试从以下位置稍微更改您正在访问的URL：

/user/populate_form&emp_id=BILL

致：

这是很容易的改变，但它应该解决你的问题

希望有帮助

根据该错误，您尚未在UsersController中定义show action，是否可以检查是否有，或者是否拼写错误？根据您显示的代码，它丢失了更新的用户控制器。。但现在我得到了一个新的错误，它在rake routes框下面@Pawełdawczakhm。。。在rake routes下面的框中没有错误。。。你能提供它吗？这并不是一个真正的错误，它只是返回null--…开始在2015-03-23 17:52:29-0400由UserControllershow处理127.0.0.1的GET/user/populate\form&emp\u id=BILL:{id=>populate\form&emp\u id=BILL}视觉加载2.2ms选择EMPLOYEE.*从EMPLOYEE中，EMPLOYEE.id为null和ROWNUM

user GET /user/:id

/user/populate_form&emp_id=BILL

/user/populate_form?emp_id=BILL
