Ruby on rails 从一个具有不同属性的窗体创建一个模型的多个对象'；价值观

我需要一次以一种形式创建两个相似的对象。但是这个对象（aviaslers）应该用不同的html来构建。对象是aviasaler_（一边卖票的aviasaker）和aviasaler_（背面卖票的aviasaker）。我试图找出如何生成两个对象，而不是创建类似的模型

我的尝试看起来像以下代码。但它不起作用。请帮助我了解如何重新调整这种方法，不要制作两个类似的模型

 @trip = Trip.new
 aviasaler_there = @trip.aviasalers.build

 @trip = current_user.trips.build(params[:trip])
 if @trip.save
   flash[:success] = "Trip created!"
   redirect_to root_url
 else
   render 'new'
  end

你如何区分那里的

avisaler\u

和后面的

avisaler\u

？如果您不是，那么您可能应该。可能是布尔型，或者最好是引入另一个表

avisaler\u类型

，您可以从

avisaler

模型中引用该表。另请参见@swapnilabnave，感谢您的回复。例如，我可以将布尔类型的“：back”属性添加到avisaler。如何在新操作中创建两个表单，其中第一个表单应使用属性（back:false）创建avisaler，第二个表单应使用属性（back:true）创建avisaler？
