Is it possible to get the ID of an entity before it is created?

Hi all,

I’m writing a slug system for one of my entities (let’s call it article), but I have a problem that sounds strange.

I need to generate a prefix + ID slug.

The prefix is a fixed string determined by the entity type. For example, article is [ac].
ID is the id of that article.

When we put them together, the slug will be something like ac29.

I managed to update and fix the slug after the article updates, but I couldn’t get the ID when creating the entity in order to generate the slug, because beforeCreate only supports data and doesn’t seem to contain the ID (because it’s the data I passed in?).

Code in ./api/article/models/article.js

const slug = require('slug');
module.exports = {
  lifecycles: {
    //Problem part
    beforeCreate: async (data) => {
      if (data.title) {
        data.slug = slug(data.title);
      }
    },
    //Perfect code, but it's too late
    beforeUpdate: async (params, data) => {
      if (data.slug) {
        data.slug = slug(data.prefix) + params.id;
      }
    },
  },
};

Does anyone have a good idea to generate the perfect slug when creating an entity? be deeply grateful.
