How do I refresh paperclip thumbnails with an offset?

I want to refresh/recreate thumbnails with 'paperclip' that have ids above 1000, is there a way to do this?

I've tried everything but forking the gem and adding an offset to the finder.

Solution

You can use reprocess! to regenerate a specific set of Paperclip images. Something like:

Model.where('parent_id > 1000').each do |model|
  model.paperclip_attachment.reprocess!
end

There's more information available in the paperclip documentation:
