可以在mongoose中使用子文档吗？

Is it possible to have nested schemas in mongoose and have a required validator on the children? Something like this:

是否可以在mongoose中使用嵌套模式并在子项上具有必需的验证器？像这样的东西：

const userSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true
  }
});

const eventSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true
  },
  host: {
    type: userSchema,
    required: true
  }
});

I can't find anything in the documentation. Thanks.

我在文档中找不到任何内容。谢谢。

i suppose you'll update eventSchema with subdocuments of type user model. you can use { runValidators: true} for update.

我想你将使用用户模型类型的子文档更新eventSchema。您可以使用{runValidators：true}进行更新。

eventModel.update({ name: 'YOUR NAME' }, { $push: { host: user } }, { runValidators: true}, function(err) {

})
