javascript - Mongo嵌套字段填充问题

Question

var buyerSchema = new Schema({
   cart: [{
       id: {
           type: Schema.Types.ObjectId,
           ref: "product"
       },
       number: Number
    }],
    personName: { type: String, required: true, trim: true },
    image: { type: String, required: false, trim: true },
    email: { type: String, required: true, trim: true }
})

我如何填充 Id 字段

buyerMdl.findByToken(buyer['token']).populate({path: 'cart', populate: {path : 'id', model : 'product'}})

这个特定的命令对我不起作用

Answer 1

你id在卡片数组里面......所以你应该使用点符号来填充id

buyerMdl.findByToken(buyer['token']).populate({ path: 'cart.id' })
