View source as generated by Rails in your browser, and see what these checkboxes look like in HTML. That's where I would start debugging this. My guess is that you need these to be supervisioncategory_ids, since that's what the b/t is saying the model is named. But without looking at the HTML, we won't know if your checkboxes are properly named to post as an array back to your controller.
