传递对象ID以为嵌套在轨道中

Question

我正在使用Rails中嵌套形式的循环，我想通过渲染局部形式传递对象ID

app / model / contract_booking_attached_trips.rb

class ContractBookingAttachedTrip < ApplicationRecord
 has_many :contract_attached_trip_sheets
 accepts_nested_attributes_for :contract_attached_trip_sheets ,allow_destroy: true
 belongs_to :booking_history
 belongs_to :duty_type
 belongs_to :vehicle_make
 belongs_to :vehicle_category
end

app / model / contract_attached_trip_sheet.rb

class ContractAttachedTripSheet < ApplicationRecord
  belongs_to :contract_booking_attached_trip
end

app / controller / contract_booking_attached_trips_controller

 def edit
   @contract_booking_attached_trip = ContractBookingAttachedTrip.find(params[:id])
   booking_history_id = @contract_booking_attached_trip.booking_history_id
   @booking_history  = BookingHistory.find(booking_history_id)
   @booking_trips = @booking_history.transport_plans
   @trip_count = @booking_history.transport_plans.count    
   @contract_booking_attached_trip.contract_attached_trip_sheets.build
end

app / views / ContractBookingAttachedTrips / _form.html.erb

我是tryinh在隐藏字段中传递transport_plan_id，但在

请告诉我如何将ID通过嵌套的渲染部分传递

Answer 1

<%= render 'contract_attached_trip_sheet_fields', :f => builder, :transport_plan =>transport_plan %>

有两种方法可以将数据传递给分部，您可以编写：

  render  partial:  'partial_name', locals: {f: builder, a: 123} 

或者简单的形式就是

  render 'partial_name', f: builder, transport_plan: transport_plan
