node.js - Sequelize 预加载 - 返回更扁平的数据对象

Question

鉴于 Sequelize 1.7.9 中的以下(工作)代码:

database.User.find({ 
    where: { signupKey: signupKey }, 
    include: [{ model: database.Company, as: "Company" }] 
}).then(function( user ) {

我的user对象输出如下内容:

{ dataValues: 
{ id: 1,
    email: 'email',
    password: '',
    firstname: null,
    lastname: null,
    companyRole: 'admin',
    nonprofitRole: null,
    signupKey: '24Pm9MZ22',
    status: 'pending',

    __eagerlyLoadedAssociations: [],
    isNewRecord: false } }

在没有急切加载的正常sequelize下，我可以记录user.values并获得一个更正常的JS对象，除了急切加载，我在记录user.values时得到这个:

{ id: 1,
email: 'email',
password: 'password',
firstname: null,
lastname: null,
companyRole: 'admin',
nonprofitRole: null,
signupKey: 'bN2dGdNbD',
status: 'pending',
createdAt: Fri Nov 21 2014 15:19:14 GMT-0500 (EST),
updatedAt: Fri Nov 21 2014 15:19:14 GMT-0500 (EST),
CompanyId: 1,
NonprofitId: null,
company: 
{ dataValues: 
    { id: 1,
        slug: 'company',
        logo: null,
        name: 'company',
        createdAt: Fri Nov 21 2014 15:19:14 GMT-0500 (EST),
        updatedAt: Fri Nov 21 2014 15:19:14 GMT-0500 (EST) },
    _previousDataValues: 
    { id: 1,
        slug: 'company',
        logo: null,
        name: 'company',
        createdAt: Fri Nov 21 2014 15:19:14 GMT-0500 (EST),
        updatedAt: Fri Nov 21 2014 15:19:14 GMT-0500 (EST) },
    __options: 
    { timestamps: true,
        createdAt: 'createdAt',
        updatedAt: 'updatedAt',
        deletedAt: 'deletedAt',
        instanceMethods: {},
        classMethods: [Object],
        validate: {},
        freezeTableName: false,
        freezeAssociations: false,
        underscored: false,
        syncOnAssociation: true,
        paranoid: false,
        whereCollection: null,
        schema: null,
        schemaDelimiter: '',
        language: 'en',
        defaultScope: null,
        scopes: null,
        hooks: [Object],
        omitNull: false,
        uniqueKeys: {},
        hasPrimaryKeys: true },
    options: 
    { isNewRecord: false,
        isDirty: false,
        include: undefined,
        includeNames: undefined,
        includeMap: undefined,
        includeValidated: true,
        raw: true },
    hasPrimaryKeys: true,
    selectedValues: 
    { id: 1,
        slug: 'company',
        logo: null,
        name: 'company',
        createdAt: Fri Nov 21 2014 15:19:14 GMT-0500 (EST),
        updatedAt: Fri Nov 21 2014 15:19:14 GMT-0500 (EST) },
    __eagerlyLoadedAssociations: [],
    isNewRecord: false } }

我希望能够运行 user.values 并获得一个平面 user 对象，就像返回的那样，并且让 user.company 也成为一个平面对象，作为 user 的子对象。 sequalize 是否提供了一种可以运行的方法，即使在急切加载的情况下，也可以让您获得像我所描述的那样组织的平面对象？

在 v3.9 中，您可以使用“get”方法将 ORM 对象转换为普通对象:

user.get({plain: true})
