如何将API参数映射到模型

2016-02-02 36 views

我是Ruby和Ruby on Rails的新手，我很努力地尝试让我的API工作。我正在尝试创建一个接受来自Shopify的POST请求的API（在我的应用程序中创建订单）。我知道正在进入的消息的结构（我正在使用curl命令中的示例消息），并且它们与我的模型的列不匹配，因此我需要映射它们。我发现很难找到有关如何做到这一点的任何文档。如何将API参数映射到模型

每次我尝试下面我得到这个错误创建使用-curl命令的命令：

ArgumentError (wrong number of arguments (15 for 0..2)): 
    app/controllers/api/v1/orders_controller.rb:16:in `create'

我的curl命令：

curl -i -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{

和我的API/V1创建函数/ orders_controller.rb

def create 
     order = Order.new(
      id = params[:id], 
      shopify_order_id = params[:id], 
      shopify_created_at = params[:created_at], 
      shopify_order_name = params[:name], 
      ship_to_name = params[:shipping_address][:name], 
      ship_to_address_1 = params[:shipping_address][:address1], 
      ship_to_address_2 = params[:shipping_address][:address2], 
      ship_to_company = params[:shipping_address][:company], 
      ship_to_city = params[:shipping_address][:city], 
      ship_to_state = params[:shipping_address][:state], 
      ship_to_country = params[:shipping_address][:country], 
      ship_to_zipcode = params[:shipping_address][:zip], 
      ship_to_phonenumber = params[:shipping_address][:phone], 
      ship_to_email = params[:shipping_address][:email], 
      store_id = 1 
     ) 
     if order.save? 
      head 200 
     else 
      head 422 
     end 
    end

谁能告诉我我做错了什么？

用'Order.create'代替'Order.new' –

你不应该使用=但是：

像这样：

order = Order.new(
     shopify_order_id: params[:id], 
     ... etc 
    )

请注意，我也省略了id属性，它会当你保存记录自动设置此。

而且改变

if order.save? 
    head 200 
else 
    head 422 
end

要：

if order.save 
    head 200 
else 
    head 422 
end

  1. 取代Order.new与Order.create，从创建散列表

  2. 和替换分配表散列

  3. 删除 'ID' 。

    所以

    order = Order.create(
    shopify_order_id: params[:id], 
    shopify_created_at: params[:created_at], 
    shopify_order_name: params[:name], 
    ship_to_name: params[:shipping_address][:name], 
    ship_to_address_1: params[:shipping_address][:address1], 
    ship_to_address_2: params[:shipping_address][:address2], 
    ship_to_company: params[:shipping_address][:company], 
    ship_to_city: params[:shipping_address][:city], 
    ship_to_state: params[:shipping_address][:state], 
    ship_to_country: params[:shipping_address][:country], 
    ship_to_zipcode: params[:shipping_address][:zip], 
    ship_to_phonenumber: params[:shipping_address][:phone], 
    ship_to_email: params[:shipping_address][:email], 
    store_id: 1)

附加说明：

最好是有指定的地址数据模型命名Address，然后因为你必须创建一个订单（使用CRUD的POST行动），任何id s和*at字段将被省略，所以你会得到类似的东西：

address = Address.where(
    name: params[:shipping_address][:name], 
    address_1: params[:shipping_address][:address1], 
    address_2: params[:shipping_address][:address2], 
    company: params[:shipping_address][:company], 
    city: params[:shipping_address][:city], 
    state: params[:shipping_address][:state], 
    country: params[:shipping_address][:country], 
    zipcode: params[:shipping_address][:zip], 
    phonenumber: params[:shipping_address][:phone], 
    email: params[:shipping_address][:email]).first_or_initialize 

order = Order.create(name: name, address: address) 
if order.persisted? 
    head 200 
else 
    head 422 
end

为什么要取代Order.new？他正在调用Order对象的保存。 – Laurens
