twitter bot running inside Rails

I've done some searches for information about running a Ruby twitter bot and found a few packages & posts, but nothing that quite seems to match what I want, which is a twitter bot running within Rails. I.e., I want simple access to all my models & data. I could hack something up using script/runner, or rufus-scheduler, but it just seems like something where someone else would have already done it and have a plugin, or at least some instructions available.

Any pointers?
