Is it possible to have one form update the parent (has) and he child objects (many) in one go. All my best efforts so far have failed for various reasons. My models are... Company: has_many telephone_numbers TelephoneNumber: number I would then like to be able to edit, add and remove telephone numbers for the company in the one form, and save everything upon submit. I have been trying this for a week now wih out any success! Martin -- Posted via http://www.ruby-forum.com/.
