Rails link_to method: GETing when it should DELETE

Issue :
Most browsers don’t actually support the DELETE verb, so Rails fakes it by modifying the HTML it generates. Rails tacks on a HTML5 attribute called data-method and sets it to "delete". So when a user clicks on the link, it is actually issued as a GET request, but the data-method attribute allows for some Rails magic and means your routing code should recognize it as a DELETE request.

View file

<%= link_to 'Sign Out', destroy_user_session_path, method: :delete, class: 'logins-link navbar-link-right' %

rails log

Started GET "/users/sign_out" for ::1 at 2022-06-17 12:44:08 +0530
Processing by UsersController#show as HTML
Parameters: {"id"=>"sign_out"}


It’s working perfectly if I use button _to instead of link_to
<%= button_to 'Delete', article_path(article), method: :delete %>

Solution :

As browsers don’t support the DELETE verb, Rails creates a workaround for this problem by simulating a DELETE request through a standard GET or POST. The way method: :delete works is with a JavaScript handler for all links with data-method="delete" which modifies the request so Rails processes it as a DELETE. This JavaScript handler is provided by the jquery_ujs library.

There are several things that could have gone wrong:

  1. Make sure you have both jquery and jquery_ujs included in your application.js. Without both nothing will process the data attributes.
  2. Make sure the link in question really has the method: :delete option specified.
  3. Make sure for some reason you haven’t stopped the event propagation of the link in question, like so for example:
$( 'a' ).click( function( event ) {

As this would prevent the jquery_ujs handlers from being executed and the request will never be modified and will remain just a standard GET.

a. application.js

//= require jquery
//= require jquery_ujs

Note that you may need to add these lines above any import statements within application.js.

b. And also make sure to includ below line in your layout file

<%= javascript_include_tag "application" %>

c. view file

<%= link_to 'Sign Out', destroy_user_session_path, method: :delete, class: 'logins-link navbar-link-right' %

d. Now rails Log

Started DELETE "/users/sign_out" for ::1 at 2022-06-17 12:47:46 +0530
Processing by Users::SessionsController#destroy as HTML
Parameters: {"authenticity_token"=>"XXXxKlhWdsfsdf435345345sfdsfsd"}

Note :

If you don’t want to include JQuery, switching link_to > button_to will fix this issue.
