How to Manage Data with a New Field (Component) in the Admin Panel

How do you write model/database changes for a custom field/component?

Similar to Field Registering - Strapi Developer Docs, I’ve created a new field/component in the admin panel but that’s where it stops, it doesn’t create a new field in the database table.

The field is working properly in the UI, I can see the data before an update. I created a lifecyles.ts file in my content-type and can see the value before and of course, it doesn’t show it after.

export default {
  beforeUpdate: (event) => {
    console.log(; // Outputs test

  afterUpdate: (event) => {
    console.log(; // Outputs undefined

I’ve managed to solve this problem after poking around the source code, I’ll reply here with a solution in the near future (unfortunately I’m working on a deadline atm).

Ping me to reply if I haven’t when you read this message :slight_smile:
