Upcoming built-in Upload Solution for Rails 5.2 (ActiveStorage)

DHH just announced a brand new feature for the upcoming Rails 5.2. This is ActiveStorage.Most simple upload solutions - such as ActiveStorage, and old ones such as the original Paperclip and the vanilla install of Carrierwave - basically set the HTML form as a multipart and add a vanilla HTML file field. This will upload the form directly to a Rails controller action, which will receive it in the params hash and you can deal with the binary blob from there.
