i am tryinh to pass transport_plan_id in hidden field but am gettting the following error in
please tell me how to pass the id through nested render partial

Answer 1

In your _form you write
<%= render 'contract_attached_trip_sheet_fields', :f => builder,{ :transport_plan =>transport_plan} %>
and that should be
<%= render 'contract_attached_trip_sheet_fields', :f => builder, :transport_plan =>transport_plan %>
There are two ways to pass data to partials, either you write:
render partial: 'partial_name', locals: {f: builder, a: 123}
or the simple form is just
render 'partial_name', f: builder, transport_plan: transport_plan
