Rails删除方法它不起作用

好吧，我在Ruby on Rails中遇到删除方法存在这样的问题，我想，我尝试了所有我读过的但是它不起作用也许你gusy可以帮助修复差距。

当我点击链接它重定向到患者/ 1？确认=是+你+确定％3F＆方法=删除

但是从我的chrome控制台收到一条消息Uncaught SyntaxError：Unexpected token =：3000 / assets / application.js？body = 1:13属于

=需要jquery

我的代码如下：

patients.controller

def show @patient = Patient.find(params[:id]) end def new @patient = Patient.new @patients = Patient.find(:all) end def create @patient = Patient.new(params[:patient]) if @patient.save redirect_to new_patient_path end end def edit @patient = Patient.find(params[:id]) end def update @patient = Patient.find(params[:id]) if @patient.update_attributes(params[:patient]) redirect_to :action => 'show', :id => @patient else @patient = patient.find(:all) render :action => 'edit' end end def destroy @patient = Patient.find(params[:id]) @patient.destroy redirect_to '/patients/new', :notice => "Your patient has been deleted" end 

show.html.erb

 
Patient Information
 
 
 
 
  |  "Are you sure?", :method => :delete %>  

申请js

 = require jquery = require jquery_ujs = require turbolinks = require_tree . 

application.html.erb

      true %>        

路线

  resources :patients match 'patients/:id' => 'patients#show', via: [:get, :post] resources :users match '/register', to: 'users#new', via: [:get, :post] resources :pages resources :sessions, :only => [:new, :create, :destroy] match '/login', to: 'sessions#new', via: [:get, :post] match '/logout', to: 'sessions#destroy', via: [:get, :post] # The priority is based upon order of creation: first created -> highest priority. # See how all your routes lay out with "rake routes". # You can have the root of your site routed with "root" root 'sessions#new' 

命令行

在2014-02-12 18:14:18 -0300开始GET“/ patients / 1？确认=你+你+确定％3F＆方法=删除”为127.0.0.1由PatientsController处理#show as HTML参数：{“confirm” >>“你确定吗？”，“方法”=>“删除”，“id”=>“1”} [1m [36mPatient Load（1.0ms）[0m [1mSELECT“患者”。*来自“患者”WHERE “病人”。“id”=？ LIMIT 1 [0m [[“id”，“1”]]在布局/应用程序内渲染patient / show.html.erb（1.0ms）在13ms完成200 OK（浏览次数：9.0ms | ActiveRecord：1.0ms）

谢谢你的帮助！

Answer 1

 <%= link_to "Delete", patient_path(@patient), :confirm => "Are you sure?", :method => :delete %> 

更新

application.js应该是

 //= require jquery //= require jquery_ujs //= require turbolinks //= require_tree . 

不

 = require jquery = require jquery_ujs = require turbolinks = require_tree . 

Answer 2

也许你有一个validation错误。 更新delete方法以在destroy之后使用bang，因此它显示输出。 这应该至少可以帮助您调试当前的情况。 否则提供更多细节，我可以更新答案。

def destroy @patient = Patient.find(params[:id]) @patient.destroy! redirect_to '/patients/new', :notice => "Your patient has been deleted" end
def destroy @patient = Patient.find(params[:id]) @patient.destroy! redirect_to '/patients/new', :notice => "Your patient has been deleted" end 

Answer 3

在

<%= link_to "Delete", :confirm => "Are you sure?", :method => :delete %>

你错过了path部分

<%= link_to "Delete", destroy_patient_path, :confirm => "Are you sure?", :method => :delete %>

Answer 4

您需要添加要删除的对象：

 <%= link_to "Delete", @patient, :confirm => "Are you sure?", :method => :delete %> 

Answer 5

您需要在视图中…有不同的方法来传递变量

 <%= link_to "Delete", destroy_patient_path, :confirm => "Are you sure?", :method => :delete %> 

然后在您的routes.rb中

 #more member routes probably need definition but not showing them here resources :patients do member do get :show post :show delete :destroy end end 

问题是您没有定义路线，并且您没有提供呼叫路径
