Sequelize：构建并保存包含数组的对象

Question

在 Sequelize.js 中构建和保存时，是否可以指定一个数组或必须在单独的 sequelize 构建中完成？

模型定义：

var Tag = sequelize.define('Tag', {
    name: Sequelize.STRING
});

var Event = sequelize.define('Event', {
    name: Sequelize.STRING,
});

Event.hasMany(Tag, {as: 'tags', through: 'event_tags', foreignKey: 'eventId'});
Tag.hasMany(Event, {as: 'events', through: 'event_tags', foreignKey: 'tagId'});

我要问的是这是否可能：

Event.build({
    name: 'blah',
    tags: [{id: 53, name: someTag}, {id: 54, name: otherTag}]

}).save().success(function(event) {...});

如果这不可能，我必须为每个 eventTag 关联进行构建吗？

Event.build({
    name: 'blah',

}).save().success(function(event) {

     // ...How? because the association (table event_tags) is not an entity
     // from which I could run .build()
     // Maybe using push?
});

来自续集文档：Sequelize Associating Objects

Event.hasMany(Tag)
Tag.hasMany(Event)

Event.create()...
Tag.create()...
Tag.create()...

// save them... and then:
event.setTags([tag1, tag2]).success(function() {
  // saved!
})

'create()' 结合了 build() 和 save()。
