node.js - Mongoose 嵌套架构验证不起作用

Question

我有以下 Mongoose 模型:

RequestSchema = mongoose.Schema(
  merchant: 
     type: String
     required: true
  products: [ 'Product' ]
)
Request = mongoose.model('Request', RequestSchema)

ProductSchema = mongoose.Schema(
  _type: String 
  product_id:
    type: String
    required: true
  quantity:
    type: String
    required: true

)
Product = mongoose.model('Product', ProductSchema)

但是，当我传入以下请求(缺少数量)时，它会被验证并保存到数据库中:

{"merchant": "ABC", "products":[{"product_id":"12345"}]} 

但是，当我尝试忽略商家时，它会在尝试保存它时给出架构验证错误:

{"products":[{"product_id":"12345", "quantity": "1"}]} 

如何才能使它们都返回验证错误？

Answer 1

当您想要使用子文档并验证它们时，您需要引用架构对象:

ProductSchema = mongoose.Schema(...)

RequestSchema = mongoose.Schema(
  merchant: 
    type: String
    required: true
  products: [ ProductSchema ]
)

这将在第一个文档上产生验证错误:

ValidationError: Path `quantity` is required.
