I was using a variable called hoh in the household (master) record. This was holding the id number of the person (child) record selected. This worked fine for existing records, but got lost with records created at the time of the save, as these records had no id yet. Someone else suggested that I put the hoh variable in the person records, but if I do this, each radio button is separate, and there is no way to allow only one selection. It seems to me that there must be a way to do this with Active Record Callbacks. After the record is created, it has an id. Couldn't I test each person record after create, and if it has the radio button selected, pass the id to the Household.hoh variable.. But for this... Is there a way to tell if the radio button is selected if it points to a variable somewhere else ?? Or is there a way to get Rails to just do this at the right time the way it does with parent/ child records, setting all id's and parent_id's ?? Too many question marks.
