document.images.attach([ first_blob, second_blob ])

def attach(*attachables)
  attachables.flatten.collect do |attachable|
    if record.new_record?
      attachments.build(record: record, blob: create_blob_from(attachable))

    end
  end

# File activestorage/lib/active_storage/attached/many.rb, line 48
def purge
  if attached?
    attachments.each(&:purge)
    attachments.reload
  end
end
purge_later()

Purges each associated attachment through the queuing system.

# File activestorage/lib/active_storage/attached/many.rb, line 56
