Custom objects are new record types your app adds to a workspace — Post Card, Invoice, Subscription, anything specific to your domain. Each object declares its schema (fields, relations, default values) and a stable universal identifier that survives across syncs and deploys.

Hauptpunkte

  • Der universalIdentifier muss eindeutig und über Deployments hinweg stabil sein.
  • Jedes Feld benötigt name, type, label und einen eigenen stabilen universalIdentifier.
  • Das Array fields ist optional — Sie können Objekte ohne benutzerdefinierte Felder definieren.
  • Inline fields defined here do not need an objectUniversalIdentifier — it’s inherited from the parent object. Use defineField() to add fields to objects you don’t own.
  • You can scaffold new objects with yarn twenty add object, which guides you through naming, fields, and relationships. See Architecture → Scaffolding entities.
Base fields are added automatically. When you define a custom object, Twenty creates standard fields like id, name, createdAt, updatedAt, createdBy, updatedBy, and deletedAt for you. You don’t need to declare them in your fields array — only your custom fields. You can override a default field by declaring one with the same name, but this is rarely a good idea.

  • Connect this object to others — see Relations for the bidirectional relation pattern.
  • Add fields to objects from other apps — see Extending Objects for defineField().
  • Display this object in the UI — see Views and Navigation Menu Items to put it in the sidebar.
