Upload Active Storage Attachments to Specific Path

If you've ever wanted to organize your bucket while using Active Storage, it looks like this is now possible as of Rails 6.1

By passing the key argument to #attach, you can specify the location of the file within the bucket -

class Invoice < ApplicationRecord
  has_one_attached :document
end

invoice = Invoice.create
invoice.document.attach(
  key: "invoices/invoice_1_20230505.pdf",
  io: File.read("invoice_1.pdf")
)
