Hi Bente, Thanks for your reply. > You should use > accepts_nested_attributes_for :department > in your employee model.
The code you provided needed a minor tweak: <% form.fields_for @employee.department do|department_fields| %> was throwing an ActiveRecord::AssociationTypeMismatch - Department(#77492292) expected, got HashWithIndifferentAccess(#37082688) After a bit of googling I changed it to: <% form.fields_for :department do|department_fields| %> and everything worked fine. Thank you once again. P.S. In case it helps anyone else, this is described very well here: http://guides.rubyonrails.org/2_3_release_notes.html#nested-object-forms -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
