Disable Active Storage in Rails 5.2 - rails-activestorage

Question

Upgrading Rails to 5.2, and I found out that I must commit the storage.yml into version control. I don't plan to use ActiveStorage. Is there a way to disable it?

Answer 1

Remove next line from config/application.rb
require "active_storage/engine"
Remove next line from environments config/environments/*.rb
config.active_storage.service = :local
Remove next line from app/assets/javascripts/application.js
//= require activestorage
ActiveStorage rails routes will vanish
In case there is statement require 'rails/all' in application.rb then you can use solution provided below where you need to require dependency by dependency and to omit active_storage.

Answer 2

The only solution I've found so far is in config/application.rb, replacing:
require 'rails/all'
With:
require "rails"
# Include each railties manually, excluding `active_storage/engine`
%w(
active_record/railtie
action_controller/railtie
action_view/railtie
action_mailer/railtie
active_job/railtie
action_cable/engine
rails/test_unit/railtie
sprockets/railtie
).each do |railtie|
begin
require railtie
rescue LoadError
end
end
which is taken from Rails' source.

Answer 3

Remove lines like the following from config/environments/*.rb
config.active_storage.service = :local
Rails will then not load the yaml file.
