Edit Question
Title
Body
I have an optional URL param, say "user_id" I need to check for. I know I can use if params.has_key?(:user_id) ... to do things based on the presence of the user_id parameter, but sometimes user_id is passed without a value, so I want to ignore it completely. To fight the issue, I find myself doing this a lot--but there's got to be a better way, right? if params[:user_id] && !params[:user_id].empty? # Do stuff end It just seems really ugly.
