Rails nested form for one to many to be shown only once -

i have got 2 models event , eventlocation .event has_many eventlocations . using nested simple nested form accepting eventlocation attributes in 'event' form

i have other view conferences. difference between event , conferences events have single event location conference have multiple event locations . there way show event_location form 1 time in event views. right able display event_location form in next way

= f.simple_fields_for :event_locations |event_location| = event_location.input :location %br = event_location.input :start_time %br = event_location.input :end_time %br = event_location.input :address = f.link_to_add "add event location".html_safe, :event_locations

but gives me alternative of adding multiple locations event ,which don't want.
