Question

我有3个模型model1 model2 model3，它的架构看起来像这样-

const model1Schema = new Schema ({
    //dummy data
    _model2SchemaAssociated: [{type: mongoose.Schema.Types.ObjectId ref:'model2'}],
    _model3SchemaAssociated: [{type: mongoose.Schema.Types.ObjectId ref:'model3'}]
});


const model2Schema = new Schema ({
    //dummy data

    _model1SchemaAssociated: [{type: mongoose.Schema.Types.ObjectId ref:'model1'}],
    _model3SchemaAssociated: [{type: mongoose.Schema.Types.ObjectId ref:'model3'}]
});

const model3Schema = new Schema ({
    //dummy data

    _model1SchemaAssociated: [{type: mongoose.Schema.Types.ObjectId ref:'model1'}],
    _model2SchemaAssociated: [{type: mongoose.Schema.Types.ObjectId ref:'model2'}]
});

无论何时将新文档添加到上述任何模型中，我都想更新associatedSchemas。

我的解决方案 只要保存了任何架构，就查找其他2个模型。并更新当前架构

但是我觉得这是一个效率低下的操作。

有没有更好的方法来解决这个问题？
