我正在建立一个会员可以购买视频的视频市场。但是，我正在努力创建订单，以便它具有 video_id、member_id 和价格。这是我的代码：

视频型号：

 has_many :members, through: :orders
 has_many :orders
 accepts_nested_attributes_for :orders

会员型号：

  has_many :orders
  has_many :videos, through: :orders
  accepts_nested_attributes_for :orders

订购型号：

attr_accessible :price, :stripe_card_token, :member_id, :video_id

  belongs_to :video
  belongs_to :member

  accepts_nested_attributes_for :video
    accepts_nested_attributes_for :member

    validates :member_id, presence: true
    validates :video_id, presence: true
    validates :price, presence: true

  attr_accessor :stripe_card_token

    def save_with_stripe
        video = @video.find_by_id(params[:id])
        member = @member.find_by_id(params[:id])
    if valid?
      @order = Stripe::Charge.create(
        amount: video.price,
        currency: "gbp",
        card: stripe_card_token,
        description: member.email
      )

      save!
    end
  rescue
    errors.add :base, "There was a problem with Stripe"
  end

订单控制器：

def new
      @order = Order.new
      build_order
end

def create
  @order = Order.new(params[:order])
  if @order.save_with_stripe
      flash[:success] = "Enjoy the video!"
  else
    render partial: 'shared/buynow'
  end
end

def build_order
    @order.build_member(
      member_id: @member.id,
      video_id: @video.id,
      price: @video.price,    
      )
  end

我认为我的问题出在“build_order”方法的某个地方，但我尝试了各种不同的方法，最终得到了各种不同的错误。

It works in my console:

[221] pry(main)> Order.create(member_id: "36", video_id: "99", price: "1000")
   (0.2ms)  BEGIN
  SQL (0.6ms)  INSERT INTO "orders" ("created_at", "member_id", "price", "stripe_card_token", "updated_at", "video_id") VALUES ($1, $2, $3, $4, $5, $6) RETURNING "id"  [["created_at", Fri, 18 Oct 2013 14:50:09 UTC +00:00], ["member_id", 36], ["price", 1000], ["stripe_card_token", nil], ["updated_at", Fri, 18 Oct 2013 14:50:09 UTC +00:00], ["video_id", 99]]
   (0.5ms)  COMMIT
=> #<Order id: 3, video_id: 99, member_id: 36, stripe_card_token: nil, price: 1000, created_at: "2013-10-18 14:50:09", updated_at: "2013-10-18 14:50:09">

对我做错的任何帮助将不胜感激。

干杯，马克

您为什么要尝试通过订单构建成员对象？看起来您已经有了会员和视频，那么为什么不将相同的哈希值传递给对 new 的调用呢？

例如

@order = Order.new(member_id: @member.id, video_id: @video.id, price: @video.price)
