如何在猫鼬中填充具有对象数组的对象? [英] How to populate object having array of object in mongoose?

问题描述

我想将 adminId 路径填充到 User 模型.
这是代码

I want to populate the adminId path to User Model.
Here is the code

adminInfo: {
    _id: false,
    adminId: [{
      type: Schema.Types.ObjectId,
      ref: 'User'
    }]
 }

这是用户架构的一部分:

Here is a part of user schema:

// user schema
const UserSchema = new mongoose.Schema({
  name: {
    firstName: {
      type: String,
      trim: true,
      required: true,
    },
    lastName: {
      type: String,
      trim: true
    }
  },
  email: {
    type: String,
    trim: true,
    required: true,
    unique: true,
    lowercase: true
  },
  phone: {
    type: String,
    trim: true,
    minlength: 10,
  },
  password: {
    type: String,
    trim: true,
    required: true,
    minlength: 6
  }
});

我尝试使用 .populate('adminInfo.adminId') 但它给出了空数组 [] 而 .populate('adminInfo') 给出了一组管理员 ID但没有填充到用户模型

I have tried using .populate('adminInfo.adminId') but it's giving empty array [] whereas .populate('adminInfo') giving array of admins ids but not getting populated to User model

推荐答案

我认为 .populate('adminInfo.adminId') 方法没有任何问题.

i don't think there is any problem with .populate('adminInfo.adminId') method.

您确定 ref 字段在 CamelCase 中.

are you sure that ref field is in CamelCase .

如果不是，请尝试更改引用字段 ->

If not, try to change ref field ->

adminInfo: {
  _id: false,
  adminId: [{
    type: Schema.Types.ObjectId,
    ref: 'user'
  }]
}
