问题描述

我正在尝试将bcrypt-nodejs包与我的sequelize模型一起使用，并且试图遵循将散列合并到模型中的教程，但是在generateHash处出现错误.我似乎无法弄清楚这个问题.有没有更好的方法来合并bcrypt?

I'm trying to use the bcrypt-nodejs package with my sequelize model and was tring to follow a tutorial to incorporate the hashing into my model, but I'm getting an error at generateHash. I can't seem to figure out the issue. Is there a better way to incorporate bcrypt?

错误:

/Users/user/Desktop/Projects/node/app/app/models/user.js:26
User.methods.generateHash = function(password) {
                          ^
TypeError: Cannot set property 'generateHash' of undefined
    at module.exports (/Users/user/Desktop/Projects/node/app/app/models/user.js:26:27)
    at Sequelize.import (/Users/user/Desktop/Projects/node/app/node_modules/sequelize/lib/sequelize.js:641:30)

型号:

var bcrypt = require("bcrypt-nodejs");

module.exports = function(sequelize, DataTypes) {

var User = sequelize.define('users', {
    annotation_id: {
        type: DataTypes.INTEGER,
        autoIncrement: true,
        primaryKey: true
    },
    firstName: {
        type: DataTypes.DATE,
        field: 'first_name'
    },
    lastName: {
        type: DataTypes.DATE,
        field: 'last_name'
    },
    email: DataTypes.STRING,
    password: DataTypes.STRING,

}, {
    freezeTableName: true
});

User.methods.generateHash = function(password) {
    return bcrypt.hashSync(password, bcrypt.genSaltSync(8), null);
};

User.methods.validPassword = function(password) {
    return bcrypt.compareSync(password, this.local.password);
};
    return User;
}

推荐答案

方法应该在sequelize.define

const bcrypt = require("bcrypt");

module.exports = function(sequelize, DataTypes) {
    const User = sequelize.define('users', {
        annotation_id: {
            type: DataTypes.INTEGER,
            autoIncrement: true,
            primaryKey: true
        },
        firstName: {
            type: DataTypes.DATE,
            field: 'first_name'
        },
        lastName: {
            type: DataTypes.DATE,
            field: 'last_name'
        },
        email: DataTypes.STRING,
        password: DataTypes.STRING
    }, {
        freezeTableName: true,
        instanceMethods: {
            generateHash(password) {
                return bcrypt.hash(password, bcrypt.genSaltSync(8));
            },
            validPassword(password) {
                return bcrypt.compare(password, this.password);
            }
        }
    });

    return User;
}
