All rb files are executed in the server. If you want to check the file *before* uploading it you will have to do it in the client pc, presumably in javascript. I don't know whether this is even possible, I doubt it. Do you think it would be a good thing if a web page could look inside files on your pc? I think you will have to upload it and then do the work. Are you a beginner at rails? If so then I suggest you work through a good tutorial such as railstutorial.org (which is free to use online).
