如何创建getter和setter覆盖? [英] How do I create getter and setter overrides?

问题描述

我想用猫鼬加密类似于此示例的字段: https://gist.github. com/kljensen/7505729

I'd like to encrypt fields similar to this example with mongoose: https://gist.github.com/kljensen/7505729

上面链接中的代码将字段映射到get的自定义decrypt()函数和set的encrypt()函数.

The code in the above link maps a field to a custom decrypt() function for get and an encrypt() function for set.

这将导致纯文本值在保存时被加密，而在检索时被解密.

This causes the plain text value to be encrypted when saved, and decrypted when retrieved.

我该如何在Loopback中覆盖模型属性的获取器和设置器?

How would I override getters and setters for a model property in Loopback?

推荐答案

您可以按以下步骤设置setter和getter:

You can set up setter and getter as follows:

<Model>.setter['myProp'] = function(val) {};

请参见LoopBack的常见/型号/user.js

See an example in LoopBack's common/models/user.js
