Rename the tip_ids to tip_id. A radio button only returns one value, and tip_ids means you are expecting an array back, as you would get from a group of checkboxes. Check your strong parameters (permit) clause in your controller -- make sure that it is set to accept a single scalar value for that form input (singular). Also check that the relationship in your models is not one to many, but one to one (has_one/belongs_to). Changing the type of input you want to use has ramifications for your entire application, not just the view.
