Edit Question
Title
Body
I've got a model which has a video attached with Paperclip . After it saves I use the saved video to generate a thumbnail. I need to do this after every save, even when a new video hasn't been uploaded, because the user can change the time where the thumbnail is captured. I am currently using after_post_process to do this, but it will only generate the thumbnail when uploading a file (this is a callback which is part of Paperclip). I would ideally use an after_save callback like this: after_save :save_thumbnail def save_thumbnail #generate thumbnail... self.update_attributes( :thumbnail_file_name => File.basename(thumb), :thumbnail_content_type => 'image/jpeg' ) end Unfortunately update_attributes calls save, which then calls the before_save callback causing an infinite loop. Is there a simple way to circumvent this behaviour?
