javascript - 如何使用字段填充用户对象

Question

这些是我从配置文件 API 的 get 请求中获得的对用户的响应

"user": "5cc3a4e8d37a7259b45c97fe"

我正在寻找的是

"user":{
    "_id": "5cc3a4e8d37a7259b45c97fe",
    "name":"Jhon Doe",

}

这是我的代码:

Profile.findOne({ 
        user: req.user.id
    })
    .populate('user',['name']) // I added this line to populate user object with name
    .then(profile=>{
        if(!profile){
            errors.noprofile = 'There is no profile for this user'
            return res.status(404).json(errors);
        } 
            res.json(profile)

    })
    .catch(err => res.status(404).json(err));

但是，我收到这些错误:

{
    "message": "Schema hasn't been registered for model \"users\".\nUse mongoose.model(name, schema)",
    "name": "MissingSchemaError"
}

我错过了什么

配置文件架构

const ProfileSchema = new Schema({
    user:{
        type: Schema.Types.ObjectId,
        ref: 'users'
    },
    handle: {
        type: String,
        required: true,
        max: 40
    },
    company: {
        type: String
    },
    website: {
        type: String,
    }
})

这是我的用户架构的样子

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

// Create Schema

const UserSchema = new Schema({
    name:{
        type: String,
        required: true,
    },
    email:{
        type: String,
        required: true,
    },
    password:{
        type: String,
        required: true,
    },
    avator:{
        type: String,

    },
    date:{
        type: Date,
        default: Date.now,
    }
});



module.exports = User = mongoose.model('Users', UserSchema)

您在Profile 架构中引用的架构是users，但您已将用户架构保存为Users。所以我想说你需要更新你的 Profile 架构:

const ProfileSchema = new Schema({
    user:{
        type: Schema.Types.ObjectId,
        ref: 'Users'
    },
    handle: {
        type: String,
        required: true,
        max: 40
    },
    company: {
        type: String
    },
    website: {
        type: String,
    }
})

可以在此行中找到保存您的用户架构的名称

module.exports = User = mongoose.model('Users', UserSchema)
