如何在不定义架构的情况下使用Mongoose? [英] How do you use Mongoose without defining a schema?

问题描述

在Mongoose的早期版本(用于node.js)中，可以选择使用它而不定义架构

In previous versions of Mongoose (for node.js) there was an option to use it without defining a schema

var collection = mongoose.noSchema(db, "User");

但是在当前版本中，"noSchema"功能已被删除.我的架构可能会经常更改，并且确实不适合已定义的架构，因此，有没有一种新方法可以在猫鼬中使用无架构的模型?

But in the current version the "noSchema" function has been removed. My schemas are likely to change often and really don't fit in with a defined schema so is there a new way to use schema-less models in mongoose?

推荐答案

我认为这就是您要寻找的猫鼬严格

I think this is what are you looking for Mongoose Strict

选项:严格

strict选项(默认情况下启用)可确保添加到模型实例中的，未在我们的架构中指定的值不会保存到数据库中.

The strict option, (enabled by default), ensures that values added to our model instance that were not specified in our schema do not get saved to the db.

注意:除非有充分的理由，否则请不要将其设置为false.

    var thingSchema = new Schema({..}, { strict: false });
    var Thing = mongoose.model('Thing', thingSchema);
    var thing = new Thing({ iAmNotInTheSchema: true });
    thing.save() // iAmNotInTheSchema is now saved to the db!!
