My Mistake. If anyone else is interested, I have been handling all my code for this app through jquery and ajax calls. I didn't realise that each form in the formset had a hidden field with its id. As I was creating a new object for these formsets to relate to, all ids in the formset needed to be set to u'' in order for new ones to be created that were associated with the new object...if that makes sense!
Thanks anyway :) On Sep 9, 2:53 pm, chewynougat <peter_i_campb...@hotmail.co.uk> wrote: > Hi, > > I have instances in my code where I need to save an object with a new > pk.
