好吧，我在 Ruby on Rails 中的删除方法遇到了这样的问题，我想，我尝试了我阅读的所有内容，但它不起作用也许你可以帮助解决这个差距。

当我单击链接时它重定向到患者/1?confirm=Are+you+sure%3F&method=delete

但也从我的 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：

患者控制者

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

显示.html.erb

<h2>Patient Information</h2>
<%= @patient.firstname %><br /> 
<%= @patient.lastname %><br />
<%= @patient.phone %><br /> 
<p> <%= link_to "Edit", edit_patient_path %> |  <%= link_to "Delete", :confirm => "Are you sure?", :method => :delete %> </p>

应用程序js

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

应用程序.html.erb

<!DOCTYPE html>
<html>
<head>
<title>Registration Patient System</title>
<%= stylesheet_link_tag    "application", media: "all", "data-turbolinks-track" => true %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
</head>
<body>

<%= yield %>

</body>
</html>

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?confirm=Are+you+sure%3F&method=delete" for 127.0.0.1 18:14:18 -0300 由 PatientController#show 作为 HTML 参数处理：{"confirm" =>“你确定吗？”、“方法”=>“删除”、“id”=>“1”} [1m[36mPatient Load (1.0ms)[0m [1mSELECT "patients".* FROM "patients" WHERE “病人”。“身份证”=？LIMIT 1[0m [["id", "1"]] 在布局/应用程序中渲染患者/show.html.erb (1.0ms) 在 13ms 内完成 200 OK (Views: 9.0ms | ActiveRecord: 1.0ms)

谢谢你的帮助！

<%= 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 .

不是

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

也许您遇到了验证错误。更新 delete 方法以在销毁后使用 bang 以显示输出。这至少应该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

在

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

你错过了这个path部分

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

你需要在你的观点......有不同的方式来传递变量

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

然后在你的 routes.rb

#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，也没有提供呼叫路径

您需要添加要删除的对象：

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