【问题描述】：

无法删除rails中的帖子，每当我单击删除按钮时它什么都不做，它甚至不显示确认消息或任何错误。我应该如何解决这个问题？除了下面所述的详细信息之外，我还应该提供更多详细信息吗？

posts_controller.rb

class PostsController < ApplicationController

 def index
    @posts =Post.all

 end

 def show
    @post = Post.find(params[:id])
 end


 def new
   @post= Post.new
 end

 def create
    @post = Post.new(post_params)
    @post.save
    redirect_to @post
 end

 def edit
    @post = Post.find(params[:id])
 end

 def update
    @post= Post.find(params[:id])
    if(@post.update(post_params))
        redirect_to @post
    else
        render'edit'
    end

 end

 def destroy
    @post= Post.find(params[:id])
    @post.destroy

    redirect_to posts_path
 end



 private def post_params
    params.require(:post).permit(:Name, :Country, :Details)
 end

 end

show.html.erb

<%= link_to "Edit", edit_post_path(@post), :class => 'btn btn-default' %>
<%= link_to "Delete", post_path(@post), 
                    method: :delete,
                    data: {confirm:'Are you Sure?'},
                    :class => 'btn btn-danger' %>

edit.html.erb

<h1>Edit Vacation</h1>

<%= form_for :post, url: post_path(@post), method: :patch  do |f| %>

<p>
<%= f.label :Name %><br>
<%= f.text_field( :Name, {:class=> 'form-control'} )%>
</p>

<p>
<%=f.label :Country %><br>
<%= f.text_field( :Country, {:class=> 'form-control'}) %>
</p>

<p>
<%=f.label :Details %><br>
<%= f.text_area( :Details, {:class=> 'form-control'}) %>
</p>

 <p>
 <%= f.submit({:class => 'btn btn-primary'}) %>
 </p>
 <% end %>

routes.rb

Rails.application.routes.draw do
# For details on the DSL available within this file, see 
http://guides.rubyonrails.org/routing.html

root 'posts#index'

resources :posts

end

【问题讨论】：

您已经重启了服务器，但它仍然无法正常工作？
您的日志文件中的请求是什么样的？你的app/assets/javascripts/application.js 怎么样？您的布局文件中是否包含该 JavaScript 文件？
@spickermann 我已经在上面添加了 application.js 信息，我取消了那些 require 的注释，因为之前给了我类似 Object doesn't support this property or method 的错误
您可以通过这个简单的语句检查错误 - puts @post.errors.messages 并查看终端的输出，只需将其写在您的 @post.destroy 下方，在您的控制器的 destroy 操作中。

【解决方案1】：

在您的控制器中：

def destroy
    @post.destroy
    respond_to do |format|
      format.html { redirect_to postss_url, notice: 'post was successfully destroyed.' }
      format.json { head :no_content }
    end
end

【解决方案2】：

我通过在 application.js 中评论那些 require 解决了这个问题，然后在 gem 文件中添加 gem 'coffee-script-source', '1.8.0' 之后运行 bundle update coffee-script-source 并重新启动服务器，因此我能够删除帖子
