Trouble with Ruby form methods

I'm still working with my Dungeon Crawler Sinatra app. Believe it or not, I have a problem. I'm trying to get a simple form method working to allow a user to move from one room to another by typing in the direction he wants to move and then hitting 'Submit'. So good so far, right?

Here's a link to a gist of the code I've got so far:

Working with form methods

The second file I posted in the gist is code that works, but I'm looking for a cleaner way of manipulating the information collected from the form method. Does that make sense? This is probably easy enough to do, and @jqr gave me some help with it last week, but I can't figure out how to make these form methods behave.

On a side note, do you have a problem with getting distracted with new ideas for projects when you're in the middle of a project? This seems to happen to me all the time, and I've been handling it by saving as much as I can think of in a Google Doc. I wonder how other programmers handle this? Do you just write things down in a notebook? I've been thinking about creating a template to use for these project ideas, just to keep my thoughts a bit more organized. If any of you have a template like this, or suggestions on what would be key features, I'd love to hear them.

I actually think a simple drawing application that allows me to add notes and save to the cloud would be ideal, but I haven't heard of anything like this.

Random Video Game Name Generator with Ruby

I've been working with a LOT of Javascript lately. And when I say "working with," what I mean is "finding scripts that will do what I want them to do and modifying as necessary." Wait, isn't this supposed to be a Ruby on Rails blog? What happened!?

I got back to work on my random video game name generator tonight. I basically wanted to style it a bit and find a way so that it would generate a new phrase whenever the page is reloaded and then provide a link to reload the page. Pretty easy to do with a Javascript code, but I'm not a huge fan of reloading the entire thing just to reload this bit of text. Probably a better way to handle this, right? Maybe an Ajax call? What do you guys suggest? This works but I don't like the look of it, I guess.

Anyway, here's a link to the app on Heroku:

Random Video Game Name Generator

I wanted to accomplish a few things with this project. First off, build a random name generator with Ruby, and then figure out how you run that code on the web. This was largely a matter of learning Sinatra, and when I say "learning," I mean reading a tutorial and talking to @jqr about it for a few minutes. Sinatra is like SO easy.

I've got plans for how I could expand it (don't I always? Other coders have this problem too, right?) such as allowing users to save names they especially like, then enter a short description of what the game would be like. Viewers could also look at games that had been saved, perhaps vote on them, look at most popular games, etc, etc.

I think it's getting easier for me to think about WHAT applications COULD do, now that I know a bit more about HOW they're built. That makes sense, right?
