ruby-on-rails devise omniauth dev-to-production

Rails with Devise in production mode No route matches [GET] "/users/sign_out"

I realize that this question has been asked a few times. But I have tried all of the solutions discussed on other threads and none of them have worked for me.

I am using rails v5.2.1 and ruby v2.4.1 with devise

My application works absolutely fine in development mode. As soon as I switch to production, my logout link fails with No route matches [GET] "/users/sign_out"

My logout link should trigger a DELETE not a GET

  <%= link_to('Logout', destroy_user_session_path, method: :delete) %>

Here are my routes

$rake routes | grep  sign_out
destroy_user_session DELETE   /users/sign_out(.:format)                devise/sessions#destroy

I have precompiled my assets with

 rake assets:clobber RAILS_ENV=production
 rake assets:precompile RAILS_ENV=production

I have tried the following configuration options in various combinations

# devise.rb
config.sign_out_via = :delete

# production.rb
config.public_file_server.enabled = true
config.assets.compile = true

I'm pretty new to rails and this is the first time I'm creating a production environment. So I may be making a very basic mistake, but I haven't been able to figure it out

Here is the full contents of the logs triggered by clicking the sign_out link

For what it's worth, the rest of my pages keep throwing up these errors about being unable to find my assets. I can't seem to clear those errors either. I have recompiled my assets many times and also gone through many different documents about them. As far as I can see it should work

Solution

As you already correctly pointed out, the route is for the DELETE method, so a GET request triggers a 404. The link_to helper not working with the method: option usually means that Javascript is disabled in your browser. To be on the safe side, use button_to instead of link_to.
