+1 The functionality you're interested in should be called from the controller. # pseudo-Ruby upload = Upload.new(params[:upload]) if Upload.find_by_file_name(upload.file_name) upload = Upload.find_by_file_name(upload.file_name) end You can't change "self" to "be" a different instance, but you can overwrite a variable containing one instance, with another instance. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
