Rails delete functionality is not working

Question

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])
  @article.destroy

  redirect_to articles_path
end

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:

http://localhost:3000/articles/1

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 application.js

Please tell me where I am doing mistake?

Update:

Here is my output of rake routes command:

E:\Rails\blog\bin>rake routes
(in E:/Rails/blog)
       Prefix Verb   URI Pattern                  Controller#Action

     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 127.0.0.1 at 2015-05-09 00:56:08 +0530
Processing by ArticlesController#show as HTML
  Parameters: {"id"=>"3"}
  [1m[35mArticle Load (0.0ms)[0m  SELECT  "articles".* FROM "articles"  WHERE "articles"."id" = ? LIMIT 1  [["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 application.html.erb file, I have modified the text application to default 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.

Answer 1

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.
