Rails 7 - link_to with method :delete still performs GET request

Question

I am trying to get this link to work, performing a DELETE request:

<%= link_to "Sign Out", destroy_user_session_path, method: :delete %>

However when I click on it, my browser still performs a GET request (which fails for obvious reasons):

I have read on multiple other forum posts, that this might have something to do with jquery not being included. They mentioned you would need to un-comment a line in app/javascript/application.js, however mine is pretty empty:

// Configure your import map in config/importmap.rb. Read more: https://github.com/rails/importmap-rails
import "@hotwired/turbo-rails"
import "controllers"

These forum posts were also quite old, so I suspect something has changed in the meantime.

Answer 1

As suggested here, the following will suffice:

<%= link_to "Sign Out", destroy_user_session_path, data: { "turbo-method": :delete } %>

I have tested this in my project and it seems to work fine. Thanks also to @alexts, you basically figured this out too, however the comment on GitHub even eliminated the double-request.

Answer 2

There are (at least) two ways to delete something in rails 7:

Using button_to (more prefered IMHO):

<%= button_to 'Sign Out', destroy_user_session_path, method: :delete %>

Renders an HTML form which sends a POST request with a hidden _method attribute with 'delete' value. Rails will treat this as if it has a DELETE method (and route it to products#destroy or whatever your routes are saying). Do not use this one within another form (HTML forbids one form inside another).

Using link_to:

<%= link_to 'Sign Out', destroy_user_session_path, data: {turbo_method: :delete} %>

Renders a simple a tag with data-turbo-method attribute. This link sends a real DELETE request.

If your destroy action ends with a redirect_to, some browsers will redirect to a new location with DELETE method (causing errors), so make sure to add status: :see_other parameter to redirect_to, like the guides suggest.

Confirmation

If you want to add confirmation prompt to a button above:

<%= button_to 'Sign Out', destroy_user_session_path, method: :delete,
  form: {data: {turbo_confirm: 'Are you sure?'}} %>

If you want to add confirmation to a link above:

<%= link_to 'Sign Out', destroy_user_session_path,
  data: {turbo_method: :delete, turbo_confirm: 'Are you sure?'} %>
