“摧毁”不生产 - Rails应用程序

我对Rails相当陌生。我正试图推出一本书评应用程序投入生产。我松散地基于它的在线教程。我有一个按钮，应该会从我的应用程序删除一个“书”条目。本书的展示页面上有一个删除按钮。但是，当我单击以删除图书条目时，它会重定向到该图书展示页面，而无需执行任何操作。该按钮在生产中非常完美。“摧毁”不生产 - Rails应用程序

我DID已经预编译了我的资产。所以我对于发生了什么感到困惑。

这里是Heroku的日志：

约翰 - 的MacBook-PRO：BookApp johnseabolt $

这里是我的书控制器：类BooksController中<的ApplicationController before_action：的authenticate_user！只：：new，：edit，：index，：show]

def index 
    @books = Book.all 
end 

def new 
    @book = current_user.books.new 
end 

def create 
    @book = current_user.books.build(book_params) 
    if @book.save 
     redirect_to books_path 
    else 
     render 'new' 
    end 
end 

def show 
    @book = Book.find(params[:id]) 
    if @book.reviews.blank? 
     @average_review = 0 
    else 
     @average_review = @book.reviews.average(:rating).round(2) 
    end 
end 

def edit 
    @book = Book.find(params[:id]) 
end 

def update 
@book = Book.find(params[:id]) 
if @book.update(book_params) 
    redirect_to book_path(@book) 
else 
    render "edit" 
end 
end 


def destroy 
    @book = Book.find(params[:id]) 
    @book.destroy 
    if @book.destroy 
     redirect_to books_path 
    else 
     render 'show_books_path' 
    end 
end 

private 
    def book_params 
     params.require(:book).permit(:description, :author, :category_id, :book_img, :title) 
    end 
end

这里是t的相关部分他预定的显示页面：

<div class="inner_left"> 
    <%= image_tag @book.book_img.url, :class => "book_show" %> 

     <div class="buttons"> 

      <% if user_signed_in? then %> 
       <% if current_user.id = @book.user_id %> 
        <%= link_to "Edit", edit_book_path, :class => "btn_left" %> 
        <%= link_to "Delete", book_path(@book), method: :delete, :class => "btn_right", data: {confirm: "Are you sure?"} %> 
       <% end %> 
      <% end %> 
      <br /> 
      <%= link_to "Back", root_path, :class => "btn" %> 
      <br /> 

      <%= link_to "Add Review", new_book_review_path(@book) , :class => "btn_submit" %> 
     </div> 
    </div>

这里是我的配置/ enivornments/prodection.rb文件的相关部分：

config.assets.compile = true

马克以下为正确的Dinesh更换

only: [:new, :edit, :index, :show]

，您需要更改方法：：在你的link_to中删除视图中的“删除”。 – bkunzi01

你的application.js怎么样？发布你的application.js和application.html.erb – dnsh

这个答案也可能适用于你：http://stackoverflow.com/a/21219515/2930161 – tkymtk

变化method: :destroy到method: :delete

代替

<%= link_to "Delete", book_path(@book), method: :destroy, :class => "btn_right", data: {confirm: "Are you sure?"} %>

使用

<%= link_to "Delete", book_path(@book), method: :delete, :class => "btn_right", data: {confirm: "Are you sure?"} %>

如果仍然无法正常工作，这意味着你不加载JQuery-ujs。请确保你在application.js中

//= require jquery 
//= require jquery_ujs

道歉。我正在摆弄按钮中的“删除”与“摧毁”，看它是否有效。我实际上最初有“删除”。它仍然不起作用。非常感谢您的快速响应！我编辑了我的原始文章，以更准确地反映我的代码。你知道这可能是什么吗？ –

在BooksController中类以下内容，尝试用

only: [:new, :edit, :index, :show, :destroy]
