I think there is a big problem with JavaScript files in Rails 5 apps in
Production environment on Heroku.
Steps to reproduce
Step 1: Creating a new Rails 5 App and switching to the root folder
rails new my_app --database=postgresql
cd my_app
Step 2: Generate a controller
rails generate controller static_pages
Step 3: edit the /app/controllers/static_pages_controller file
class StaticPagesController < ApplicationController
def show
end
def destroy
end
end
Step 4: create the views to show with the actions
*/app/views/static_pages/show.html.erb* :
this is the show view
here is a link to the delete action:
<%= link_to t('logout'), logout_path, method: :delete %>
*/app/views/static_pages/destroy.html.erb :*
this is the destroy view which is called with a link_to method: :delete
Step 5: edit the /config/routes.rb file
Rails.application.routes.draw do
root 'static_pages#show'
get 'static_pages/show'
delete '/logout', to: 'static_pages#destroy'
end
Step 6: check the routes
rails routes
Prefix Verb URI Pattern Controller#Action
root GET / staticpages#show
staticpages_show GET /staticpages/show(.:format) staticpages#show
logout DELETE /logout(.:format) staticpages#destroy
rails_service_blob GET
/rails/active_storage/blobs/:signed_id/*filename(.:format)
active_storage/blobs#show
rails_blob_representation GET
/rails/active_storage/representations/:signed_blob_id/:variation_key/*filename(.:format)
active_storage/representations#show
rails_disk_service GET
/rails/active_storage/disk/:encoded_key/*filename(.:format)
active_storage/disk#show
update_rails_disk_service PUT
/rails/active_storage/disk/:encoded_token(.:format)
active_storage/disk#update
rails_direct_uploads POST /rails/active_storage/direct_uploads(.:format)
active_storage/direct_uploads#create
Step 7: create the DB and migrate
rails db:create
Created database 'my_app_development'
Created database 'my_app_test'
rails db:migrate
Step 8: start the server
rails server
Step 9: go to localhost:3000/ and click the link presented. the link works
and send a delete action to the server

Step 10: create a heroku app(you have to be logged in to heroku on your
system)
heroku create
Step 11: push your work to Heroku
git add -A
git commit -m "init"
git push --set-upstream heroku master
Step 12: open your Heroku app and do like in Step 9 and fail because
JavaScript seems to not work correctly

This is either an obvious error on Rails or on Heroku's side as all you see
I did was jsut create a fresh new rails app and changed the routes,
generated a controller and made 2 views for the controller actions.
Here are the links if you want to check out all the sources for the app and
the app deployed to heroku.
You can check the source code here:
https://bitbucket.org/Jaiel/my_app/src/master/
And the app here: https://rocky-inlet-61318.herokuapp.com/
Expected behavior
Links with the method: :delete should work as intended and send out DELETE
requests
Actual behavior
Links with method: :delete send out GET requests
JavaScript not working properly
System configuration
