Active record validations. this guide teaches you how to validate the state of objects before they go into the database using active record’s validations feature. after reading this guide, you will know: how to use the built in active record validation helpers. how to create your own custom validation methods. Now, we’ll want to create a stimulus form controller that we’ll use to hook into the form submit action and manually validate our fields. import { controller } from 'stimulus'; export default class extends controller { static targets = ['form']; submitform(event) { console.log('form submitted'); } } so far, this is a pretty basic form.
