Question

我使用的是带有has_one和has_many关系的嵌套表单。问题是关联中的数据没有被保存。

以下是模型，控制器和我正在使用的视图

卖单模型

class SellOrder < ActiveRecord::Base
  belongs_to :company
  has_one    :work_order, dependent: :destroy

  accepts_nested_attributes_for :work_order, :reject_if => lambda { |a| a[:content].blank? }, :allow_destroy => true
end

工单模型

class WorkOrder < ActiveRecord::Base
  belongs_to :sell_order
  has_many   :todos, dependent: :destroy

  accepts_nested_attributes_for :todos, :reject_if => lambda { |a| a[:content].blank? }, :allow_destroy => true  
end

Todo模型

class Todo < ActiveRecord::Base
  belongs_to :work_order
end

销售订单控制器

class SellOrdersController < ApplicationController
  def new
    @sell_order = SellOrder.new(user: current_user)
    1.times {
      @work_order = @sell_order.build_work_order
      @work_order.todos.build
    }
  end

  def create
    @sell_order = current_company.sell_orders.new(sell_order_params)
    if @sell_order.save
      redirect_to [:edit, @sell_order]
    else
      1.times {
        @work_order = @sell_order.build_work_order
        @work_order.todos.build
      }
      render :new
    end
  end

  private
    def sell_order_params
      params.require(:sell_order).permit(:some_other_attributes, work_order_attributes: [todos_attributes: [:comment, :price]])
    end
end

查看

= f.fields_for :work_order do |builder_work_order|
  = builder_work_order.fields_for :todos do |builder|
    = builder.text_field :comment, class: 'form-control'
    = builder.text_field :price, class: 'form-control'

当我提交表单时，只保存卖单。工作单和待办事项表中没有数据。有没有人有这种情况的解决方案？

Rails版本：4.1.1
