Sequelize JS - 我用哪个？ Model.key.references或'Associations'？

Question

我是Sequelize的新手。当前正在处理一个小模式，需要将一个外键添加到表中，并找到以下内容：

sequelize.define(
    "my_model", {
        "id": {
            type: Sequelize.UUID,
            primaryKey: true,
            defaultValue: Sequelize.UUIDV4
        },

        ...

        "linked_model": {
            type: Sequelize.UUID,

            // Should I be using this form to create foreign keys?
            references: {
                model: MyOtherModel,
                key: id
            }
        }
    }
)

过了一会儿，我发现了关联API - http://docs.sequelizejs.com/manual/tutorial/associations.html - 它也可用于在相关表上创建外键：

const Player = this.sequelize.define('player', {/* attributes */});
const Team  = this.sequelize.define('team', {/* attributes */});

Player.belongsTo(Team); // Will add a teamId attribute to Player to hold the primary key value for Team

同样的问题也出现在这里 - Sequelize model references vs associations

这两者中的哪一个被认为是最佳做法？
