To avoid extra load to your app (saving dyno's time in Heroku), I would rather do something like this: add this method to your model with the attachment:

def download_url(style_name=:original)
  creative.s3_bucket.objects[creative.s3_object(style_name).key].url_for(:read,
      :secure => true,
      :expires => 24*3600,  # 24 hours
      :response_content_disposition => "attachment; filename='#{creative_file_name}'").to_s
end

And then use it in your views/controllers like this:

<%= link_to 'Download Creative', event.download_url, class: "btn btn-info" %>
