创建记录并向其添加关联记录

发布于 2024-08-20 03:14:52 字数 646 浏览 5 评论 0原文

我有一个以下模型

class Order < ActiveRecord::Base
    has_many :products, :through => :line_items
end
class Product < ActiveRecord::Base
    belongs_to :order
end

line_items 是一个表，它将订单与多个产品相关联。

create_table "line_items", :force => true do |t|
    t.integer  "order_id"
    t.integer  "product_id"
    t.integer  "count"
    t.datetime "created_at"
    t.datetime "updated_at"
end

因此，每个订单可以有多个产品。

我需要创建一个表单，允许用户创建订单并在其中包含一些产品。对于每种产品，可以设置数量。我认为，这个问题的经典解决方案，通过保持购物车（或购物篮）在会话中，不符合我的问题，因为我需要设置并发送所有的东西一次，而不是点击每个产品的购买按钮并等待。

是否有任何最佳实践来实现这一点？

原文

I have a following model

class Order < ActiveRecord::Base
    has_many :products, :through => :line_items
end
class Product < ActiveRecord::Base
    belongs_to :order
end

line_items is a table, that associates an Order with multiple products.

create_table "line_items", :force => true do |t|
    t.integer  "order_id"
    t.integer  "product_id"
    t.integer  "count"
    t.datetime "created_at"
    t.datetime "updated_at"
end

So, each order can have multilple products.

I need to create a form, that allows user to create an order and to include some products to it. For each product, the quantity can be setted.
I think, the classic solution of this problem, via keeping a cart (or basket) in session, not matches my problem, because i need to setup and send all the stuff once, without clicking on each product's buy button and waiting.

Are there any best practices to implement this ?
