Upload still being processed immediately

[pawel2105]

In my development enivornment, uploads are still blocking and aren't being handled asynchronously. I've got redis and sidekiq started in development.

My stack:

delayed_paperclip (2.7.1) paperclip (4.1.1) sidekiq (3.1.0)

My model:

include Sidekiq::Worker
...
has_attached_file :photo
process_in_background :photo, processing_image_url: "path/to/img.png"

Log tailing shows processing happening synchronously:

                            :key=>"my-cool-photos/62/original/my_image.jpg")

In fact, when I kill my sidekiq process, the photo still uploads (I can see it in my S3 bucket) but photo_processing is set to true. Once sidekiq runs the job, the value just gets set to false.

I misunderstood the point of this gem. All uploads are in fact handled synchronously, the processing is delayed.
