## 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. -->

📝 Editing Content
Adding/Editing Pages
-
Edit MDX files in the appropriate directory:
user-guide/- User documentationdevelopers/- Developer documentationtwenty-ui/- Component documentation
-
Update
navigation/base-structure.jsonif you need to change the tab/group hierarchy or add/remove pages. This file stays in the repo and is not uploaded to Crowdin. -
Keep the translation template (
navigation/navigation.template.json) in sync by runningyarn docs:generate-navigation-templateafter editing the base structure. This template is the only file that should be pushed to Crowdin. -
For each translated locale pulled from Crowdin, ensure a
packages/twenty-docs/l/<language>/navigation.jsonfile exists. These files contain labels only; page slugs always come from the base structure. -
Run
yarn docs:generateto rebuilddocs.jsonfrom the base structure + translated labels.
