## Context Setting isNullable on a field via the app SDK manifest was silently ignored when re-syncing an existing field. The first sync that creates a field honored isNullable correctly, but any later manifest change to isNullable had no effect, neither on the field metadata nor on the underlying Postgres column. Two compounding gaps caused this: The diff never detected the change. isNullable was configured with toCompare: false, so compareTwoFlatEntity excluded it from the diff and no update action was ever generated. There was no DDL to apply it. Even if detected, the update field action handler only altered name, options, defaultValue, and settings. The column manager had no way to alter a column's NOT NULL constraint. ## Fix - Set isNullable.toCompare: true so manifest changes are detected and persisted to the field metadata (via the existing executeForMetadata path). - Add WorkspaceSchemaColumnManagerService.alterColumnNullable(): emits SET NOT NULL / DROP NOT NULL, with an optional pre-serialized backfill (UPDATE … WHERE col IS NULL) applied only on the nullable → non-nullable transition. - Add handleFieldNullableUpdate() to the update field action handler, dispatched after the defaultValue block so the default is in place before NOT NULL is enforced. It is composite-aware (mirrors the per-sub-column parentIsNullable || !property.isRequired rule used at column creation) and skips relation/morph join columns and TS_VECTOR, which are always nullable by design. <!-- This is an auto-generated description by cubic. --> <a href="https://cubic.dev/pr/twentyhq/twenty/pull/22362?utm_source=github" target="_blank" rel="noopener noreferrer" data-no-image-dialog="true"><picture><source media="(prefers-color-scheme: dark)" srcset="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"><source media="(prefers-color-scheme: light)" srcset="https://www.cubic.dev/buttons/review-in-cubic-light.svg"><img alt="Review in cubic" src="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"></picture></a> <!-- End of auto-generated description by cubic. -->

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
