Remove ActiveStorage by default with Rails 5.2
When you make a new Rails 5 project and take a look at the default routes that come out-of-the-box, you will see something like this:
Prefix Verb URI Pattern Controller#Action 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
This is because Rails 5.2 sets as default the usage of ActiveStorage.
I do not know if this is what most projects need, but I do know that this is extra baggage that many of my applications do not need.
If you have already started your project and you would like to get rid of this, here is a good guide that will walk you through the process of removing ActiveStorage.
But if you are just about to start a new project, and you would like the site generator to give a fresh application without this feature activated by default, you can use the following command.
rails new my_project_name --skip-active-storage
This way you will find a clean new site without any use of ActiveStorage.
