Frontend blocks

I think I've got the front-end mostly set up to handle schedule blocks and update them accordingly when the user interacts with the UI.  I'm having some trouble with the schedule API calls, though: I'm not sure how to make GET give me each block's teacher and student group IDs, and when I PUT a new schedule, it says 200 but doesn't seem to actually update the schedule on the server.  Ideally I'd like to spend some time digging into these for my own edification, but for now: any tips from our Ruby guys?
