仅填充猫鼬中的特定字段 [英] Populating only specific fields in mongoose

问题描述

我有一个这样的文档:

信息收集:

{
  infoType: "Appointment",
  contact: ObjectId("5baa28a3f1268917e9220138"),
}

联系人收集:

{
  name: "ABC",
  email: "[e-mail]"
}

我想通过在 mongoose 中使用 populate 方法只填充查询中的联系人姓名.

And I want to populate only contact name in query by using populate method in mongoose.
