Ruby Question

Rails delete functionality is not working

I am completely new to Ruby On Rails, and going through this guide to build a basic application.

When I am trying to implement the delete functionality as mentioned in the document, I am seeing the show page.

I have below method in my controller:

def destroy
@article = Article.find(params[:id])

redirect_to articles_path

and below line in my page:

<td><%= link_to 'Destroy', article_path(article),
method: :delete,
data: { confirm: 'Are you sure?' } %></td>

Now when I click on the link, I am seeing below URL in browser:


Now now in this case I am seeing the show screen instead of getting an alert message and then deleting the record from my page.

I have followed this SO post - Rails 4 link_to Destroy not working in Getting Started tutorial

and verified that

//= require jquery
//= require jquery_ujs

elements are there in my

Please tell me where I am doing mistake?


Here is my output of
rake routes

E:\Rails\blog\bin>rake routes
(in E:/Rails/blog)
Prefix Verb URI Pattern Controller#Action
welcome_index GET /welcome/index(.:format) welcome#index
articles GET /articles(.:format) articles#index
POST /articles(.:format) articles#create
new_article GET /articles/new(.:format) articles#new
edit_article GET /articles/:id/edit(.:format) articles#edit
article GET /articles/:id(.:format) articles#show
PATCH /articles/:id(.:format) articles#update
PUT /articles/:id(.:format) articles#update
DELETE /articles/:id(.:format) articles#destroy
root GET / welcome#index

This is what I get from log files when I click on Delete link:

Started GET "/articles/3" for at 2015-05-09 00:56:08 +0530
Processing by ArticlesController#show as HTML
Parameters: {"id"=>"3"}

Rendered articles/show.html.erb within layouts/application (0.0ms)
Completed 200 OK in 47ms (Views: 46.9ms | ActiveRecord: 0.0ms)

In my
file, I have modified the text
to fix an issue that I reported in this post - ExecJS::ProgramError in Welcome#index TypeError: Object doesn't support this property or method , is this the cause of my issue now? If revert the change, then the application is failing completely.

You have to use button_to instead of link_to to make it work.

Refer to this post - Rails 3 - link_to :delete is redirecting to show action with jquery installed , look at the answer given by Cypher.
