Rails刪除方法它不起作用

嗯，我在Ruby on Rails的刪除方法有這樣的問題，我想，我試過了我讀的所有內容，但它不起作用，也許你可以幫助修復差距。？Rails刪除方法它不起作用

當我點擊鏈接重定向到患者/ 1確認=爲+你+確定％3F &方法=從Chrome的控制檯未捕獲的SyntaxError刪除

而且收到的消息：意外的記號=：？3000 /資產/的application.js體= 1：13，其屬於

= require jquery

我的代碼是下面的：

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

<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>

應用JS

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

application.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>

路由

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

「它不工作」用什麼樣的路徑？ –

我點擊鏈接它什麼都不做 – rfcabal

也許這可以幫到你。 http://stackoverflow.com/questions/963420/undo-scaffolding-in-rails/963485#963485 –

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

更新

的application.js應該

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

不

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

同樣我點擊鏈接，它在患者詳細信息「顯示」中重定向到我，但它不會從數據庫中刪除患者 – rfcabal

您與jquery_ujs圖書館有鏈接嗎？ – Jacek

我從aplicattion.js中刪除//，那是什麼意思？ – rfcabal

也許你有一個驗證錯誤。更新delete方法以在銷燬後使用bang，以顯示輸出。這應該至少可以幫助你調試你的現狀。否則提供更多的細節，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

謝謝，問題解決了！ – rfcabal

良好的工作總是使用爆炸來拋出異常。 – wallerjake

在

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

你缺少的部分path

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

我收到一個錯誤顯示C：/CursoTuby/proyecto01/simpleform/app/views/patients/show.html.erb其中第7行提出：未定義的局部變量或方法'destroy_patient_path'爲＃<＃：0x42729c0> – rfcabal

您需要添加你要刪除的對象：

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

當我添加@patient時，它會在患者詳細信息「show」中重定向到我，並且它不會從數據庫中刪除患者。 – rfcabal

在瀏覽器中分享鏈接的HTML。你使用的是什麼版本的Rails？ – cortex

我正在使用Rails 4.0.2 – rfcabal

你需要在你看來...有不同的方法來傳遞變量

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

然後在你的路線。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

問題是你還沒有定義的路線，你是不是提供調用
