Question

我正在使用Rails中的api中的active_model_serializers，我有一个控制器方法，其中通过一些计算保存了发票及其嵌套项目，问题是在包括序列化程序之后，嵌套属性受到限制，我无法访问它们。

根据一些文档，我以这种方式获得了代码，但是它不起作用

#Controller

 def invoice_params
        params.require(:invoice).permit(:person_id, :date, sales_attributes: [:reference_id, :quantity, :price])
 end

#Model

class Invoice < ApplicationRecord
    belongs_to :person
    has_many :sales
    accepts_nested_attributes_for :sales, allow_destroy: true
end

#Serializer

class InvoiceSerializer < ActiveModel::Serializer
    attributes :id, :date, :total, :profit, :consecutive, :person_id
    has_many :sales, root: :sales_attributes
    belongs_to :person
end

我要发送的json请求是：

{
    "person_id": 4,
    "date": "2019-03-20",
    "sales": [
        {
            "reference_id":1,
            "quantity": 90000,
            "price": 240
        },
        {
            "reference_id":1,
            "quantity": 50000,
            "price": 240
        }
    ]
}

有人知道会发生什么吗？在加入序列化器gem之前，它工作正常。

谢谢！

更改

invalidateSessionCancelingTasks:

到

SELECT a.Customer AS Customer,
       round(100.00*sum(b.Online_Sales)/sum(a.Sales), 2) AS PctOnlineSales
FROM
 ProjectId.Dataset.Big_Data_Test_1_Sales a
JOIN ProjectId.Dataset.Big_Data_Test_1_Online_Sales b
ON a.Customer = b.Customer
--WHERE a.Customer IN ('1002')
GROUP BY 1
ORDER BY 1```

和

def invoice_params
        params.require(:invoice).permit(:person_id, :date, sales_attributes: [:reference_id, :quantity, :price])
 end

到

def invoice_params
        params.require(:invoice).permit(:person_id, :date, sales_attributes: [:id, :reference_id, :quantity, :price])
 end

如何使用活动模型序列化器允许嵌套属性？
