Parent model Object ID nil when updating child model in form - ruby-on-rails

Question

I am trying to save parent models ID and it child attributes using a join table council_history, for some reason it seems to be not saving the parent models ID in the join table but saves child attributes ID, when I try to do something similar with a many to many association everything works fine and parent object is saved, I am not sure if its my associations that are wrong, have been wrestling with multiple combinations, any help would be appreciated.
