Rails Carrierwave S3 how to return a specific file if the requested file is not found on the server?

Question

Ruby on Rails

Hello
The situation is as follows: in order to save money, I want to change the life cycle of photos uploaded to s3 to 3 months. But at the same time, I do not want to delete entities on the Rails server. Is there simply an option to check when displaying a photo from s3, its presence and, if not, to display a pre-prepared layout "Photo deleted"? Suggest a solution.
