If I want to check that someone has uploaded a standard image, would simply doing class Image def validate errors.add(:content_type, "must be an image") unless content_type and content_type.include?("image") end end So, basically checking to make sure that the content type of the image contains "image". Will that backfire at any point? I suppose I could check for "image/jpeg" or "image/gif" or whatever.
