有条件地跳过猫鼬钩子函数

本文介绍了有条件地跳过猫鼬钩子函数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个预先保存的钩子来加密 User 架构的 password 字段，例如:

I have a pre-save hook to encrypt password field of User schema, like:

var schema = new mongoose.Schema({ username: 'string', password: 'string' }); schema.pre('save', encrptPasswordHook); schema.pre('update', encrptPasswordHook); schema.pre('findOneAndUpdate', encrptPasswordHook); ...

通过这种方式，每次创建或更新 User 时，我都会在我的数据库中加密密码字符串.

By this way, I have encrypted password string in my database every time a User created or updated.

现在我有一个带有加密密码的旧 User 数据的 JSON 文件.我想使用这个 User 模型将 JSON 文件导入我的数据库.

Now I have a JSON file of old User data with the encrypted password. I want to use this User model to import the JSON file into my database.

如何避免预存钩再次加密密码?

How can avoid the pre-save hook to encrypt the password again?

推荐答案

您可以使用 User.collection.insert() 绕过所有 Mongoose 验证(插入数据的类型不会是检查)和钩子，它直接使用MongoDB驱动程序:

You can use User.collection.insert() to bypass all Mongoose validations (the type of the inserted data won't be checked) and hooks, it uses the MongoDB driver directly:

var UserSchema = new mongoose.Schema({ username: 'string', password: 'string' }); var User = mongoose.model('User', UserSchema); User.collection.insert({ username: 'Some Name', password: 'The Encrypted Password' });
