Node.js &引用；路径'；哈希密码'；“是必需的”；即使使用虚拟字段时哈希_密码字段已满

我正在尝试创建一个应用程序，其中密码被发送到一个虚拟字段，然后散列并存储为散列。然而，我不断地得到这个错误：

(node:32101) UnhandledPromiseRejectionWarning: ValidationError: User validation failed: hashed_password: Path `hashed_password` is required.

下面是我的代码，当我运行它时，我会得到代码下面包含的日志

const mongoose = require('mongoose');
const uuidv1 = require('uuid/v1');
const cryptop = require('crypto');

const userSchema = new mongoose.Schema({
    name: {
        type: String,
        trim: true,
        required: true
    },
    email: {
        type: String,
        trim: true,
        required: true
    },
    hashed_password: {
        type: String,
        required: true
    },
    salt: String,
    created: {
        type: Date,
        default: Date.now
    },
    updated: Date
});

userSchema
    .virtual("password")
    .set(password => {
        // create temporary variable called _password
        this._password = password;
        // generate a timestamp
        this.salt = uuidv1();
        // encryptPassword()
        this.hashed_password = this.encryptPassword(password);
        console.log(this);
    })
    .get(function () {
        return this._password;
    });

userSchema.methods = {
    encryptPassword: password => {
        if (!password) return "";
        try {
            return crypto
                .createHmac("sha1", this.salt)
                .update(password)
                .digest("hex");
        } catch (err) {
            return "";
        }
    }
};

module.exports = mongoose.model("User", userSchema);

错误：

当我在没有encryptPassword功能的情况下执行此操作时，仍然会出现一个错误：

const mongoose = require('mongoose');
const uuidv1 = require('uuid/v1');
const cryptop = require('crypto');

const userSchema = new mongoose.Schema({

        trim: true,
        required: true
    },
    hashed_password: {
        type: String,
        required: true
    },
    salt: String,
    created: {
        type: Date,
        default: Date.now
    },
    updated: Date
});

userSchema
    .virtual("password")
    .set(password => {
        // create temporary variable called _password
        this._password = password;
        // generate a timestamp
        this.salt = uuidv1();
        // encryptPassword()
        // this.hashed_password = this.encryptPassword(password);
        this.hashed_password = 'Test hash';
        console.log(this);
    })
    .get(function () {
        return this._password;
    });

userSchema.methods = {
    encryptPassword: password => {
        if (!password) return "";
        try {
            return crypto
                .createHmac("sha1", this.salt)
                .update(password)
                .digest("hex");
        } catch (err) {
            return "";
        }
    }
};

尝试使用

函数（密码）

而不是

密码=>

当您使用箭头功能时，

此
