How to issue a delete request in ruby on rails

In my rails app, I have a following link:

<%= link_to("Log out", logout_path, method: :delete)%>

And in my routes I added:

  delete '/logout',  to: 'sessions#destroy'

However, when I click on the Log out link, I get the following routing error:

No route matches [GET] "/logout"

It seems that even I specified "method: :delete", the "link_to" function still issues a get request instead of a delete request. How do I send a delete request with ruby on rails?

My application.js looks like this:

//= require rails-ujs
//= require activestorage
//= require turbolinks
//= require_tree .
//= require jquery
//= require jquery_ujs
//= require bootstrap

This usually occurs due to a missing JS dependency in application.js.

If you're using Rails 5, add:

//= require rails-ujs

And for earlier versions ensure you have:

//= require jquery
//= require jquery_ujs

In there.

The reason for this is that a little Rails magic 'fakes' the delete request as most browsers don't support this. It will add data-method="delete" to your HTML tag, allowing your application to recognise the request as it should be, and process as DELETE (even though it's actually sent as a GET request).

Also, ensure you're loading said Javascript via the following line in your layout:

<%= javascript_include_tag "application" %>

Let me know how you get on or if you have any questions - hope this helps.
