Displaying original image while processing as an option to :processing_image_url about delayed_paperclip HOT 3 CLOSED

Here's what I did:

process_in_background :photo, :processing_image_url => :process_image

def process_image
      options = photo.options
      options[:interpolator].interpolate(options[:url], photo, :original)
end

and everything seems to work ok at this point. Give it a go. :)

Fantastic! Thank you soo much! That is exactly what I was looking for.

plase correct me if I'm wrong, but while this method works it could be slightly improved.

Namely: suppose I process online the styles "large" and "small", but in background I process "thumbnail", "hd", "landscape", "vignette" etc..

It would be great to be able to return a different fallback depending on which style is being currently requested, e.g.

def process_image fmt
      options = photo.options
      large_formats = %i[hd landscape desktop retina]
      fallback_format = large_formats.include?(fmt) ? :large : :small 
      options[:interpolator].interpolate(options[:url], photo, fallback_format)
end

Maybe this is already possible but I have not understood how :)
