如何在猫鼬中保存objectID数组并添加字段？

Question

I am trying to save in an Array the following...

I send this by POST

req.body.products =

{id: "5936460d2fabd233f0ddaca3", buy: 30, cant:20},
{id: "5936460d2fabd233f2ddace6", buy: 25, cant:14}

That id is the ObjectId of an existing product

This is my controller

let facturaProv = new provBill({
  id_store: res.locals.store.id,
  name: req.body.name,
  category: req.body.category,
  products: req.body.products
});

facturaProv.save(function(err) {
  if (!err) res.send('OK')
  else res.send("error")
}
});

This is my Schema

provSchema: new Schema({
  id_store: { type: mongoose.Schema.Types.ObjectId, ref: 'store' },
  category:String,
  name: String,
  products: [{ type: mongoose.Schema.Types.ObjectId, ref: 'product' }]
})

How should I modify my schema to save the "buy" and "cant" fields?

I tried the following but it does not work:

products: [{ type: mongoose.Schema.Types.ObjectId, ref: 'product', buy: Number, cant:Number }]

Thank you for reading and for helping me.

Answer 1

Modify the schema as following:

products: [
  { 
     id : {type: mongoose.Schema.Types.ObjectId, ref: 'product'}, 
     buy: Number,
     cant: Number
  }
]

This is not a correct JSON object {id: "5936460d2fabd233f0ddaca3", buy: 30, cant:20}, {id: "5936460d2fabd233f2ddace6", buy: 25, cant:14}

Note the ""

{"id": "5936460d2fabd233f0ddaca3", "buy": 30, "cant":20}, {"id": "5936460d2fabd233f2ddace6", "buy": 25, "cant":14}
