How can I define and use a UUID field?

Question

I need a UUID field in a content type, with the help of the introduction below I have modified the file "MyType.settings.json".

https://strapi.io/documentation/3.x.x/guides/models.html#define-the-attributes

"uid": {
  "default": "",
  "type": "uuid"
},

I thought a UUID is automatically saved, but nothing happens.

How can I define and use a UUID field? Can someone give me a hint? Should I also modify the file \api\MyType\controllers\MyType.js?

Thanks in advance!

You will have to use uuid node module. So keep your attribute and in the lifeCyle functions, set your uuid with the lib.

'use strict';

const uuid = require('uuid');

module.exports = {
  beforeCreate: async (model) => {
    model.set('uid', uuid());
  }
};
