Have a look at the following code from spree

  def new
    @stock_movement = stock_location.stock_movements.build
  end

  def create
    @stock_movement = stock_location.stock_movements.build(stock_movement_params)
    @stock_movement.save
    flash[:success] = flash_message_for(@stock_movement, :successfully_created)
    redirect_to admin_stock_location_stock_movements_path(stock_location)
  end

Is it really necessary to build associated object in new method

@stock_movement = stock_location.stock_movements.build

or below line is fine

@stock_movement = StockMovement.new

Please explain..

Deleted my answer. @oneWorkingHeadphone is right, that answer explains it better. – NM Pennypacker May 03 '17 at 14:28
