如何用猫鼬生成ObjectId? [英] How can I generate an ObjectId with mongoose?

问题描述

我想用Mongoose生成一个MongoDB ObjectId.有没有办法从猫鼬访问ObjectId构造函数?

I'd like to generate a MongoDB ObjectId with Mongoose. Is there a way to access the ObjectId constructor from Mongoose?

• 这个问题是关于从头开始生成新 ObjectId的问题.生成的ID是全新的通用唯一ID.

• This question is about generating a new ObjectId from scratch. The generated ID is a brand new universally unique ID.

另一个问题是关于使用现有字符串表示形式创建ObjectId 的问题.在这种情况下，您已经具有ID的字符串表示形式(它可能是通用的也可能不是唯一的)，并且正在将其解析为ObjectId.

Another question asks about creating an ObjectId from an existing string representation. In this case, you already have a string representation of an ID—it may or may not be universally unique—and you are parsing it into an ObjectId.

推荐答案

您可以在require('mongoose').Types上找到ObjectId构造函数.这是一个示例:

You can find the ObjectId constructor on require('mongoose').Types. Here is an example:

var mongoose = require('mongoose');
var id = mongoose.Types.ObjectId();

id是新生成的ObjectId.

您可以在 Mongoose#Types文档Types对象的更多信息. >.

You can read more about the Types object at Mongoose#Types documentation.
