## Context Fixes twentyhq/core-team-issues#2749: when an app manifest creates an object and its relation fields in a single sync, the engine-owned INDEX view ended up with no viewField at all for RELATION / MORPH_RELATION fields, not even a hidden one. Adding the same relation to a pre-existing object in a second sync produced a visible viewField. ## Root cause `fieldIndexViewFieldOnCreate` is the sole owner of caller-field view fields on the INDEX view (`objectSystemFieldsAndIndexViewOnCreate` only emits view fields for displayable system fields). Its same-batch branch gated on `isFlatFieldMetadataDisplayableInDefaultView`, which excludes RELATION / MORPH_RELATION, so relations were dropped and nothing else picked them up. The guard's other exclusions (reserved names like `id`/`deletedAt`, system-only types TS_VECTOR / POSITION) are unreachable there: side effect handlers only trigger on caller-authored entities (the engine reads triggers from the pre-expansion matrix), and the flat field validators reject those names/types for caller fields. The guard could only ever drop relations. ## Fix - Remove the displayability guard from `buildViewFieldForObjectCreatedInSameBatch`. - Remove the `displayableOnly` filter from `computeCallerFlatFieldMetadatasForObject`: every caller field now gets a view field, and both handlers keep deriving positions from the same list, so the interleaved layout stays consistent by construction (label identifier, caller fields in input order with relations, then displayable system fields). - Build the view field literal through a single `buildIndexFlatViewFieldToCreate` helper on all handler branches instead of `computeFlatViewFieldsToCreate`, whose internal displayability filter would have dropped relations again. That util keeps its semantics for its remaining callers (system-field view fields, object creation via API, committed upgrade commands). Both identifier derivations are the same deterministic uuid (asserted by an existing twenty-shared spec), so emitted identifiers are unchanged. - `isFlatFieldMetadataDisplayableInDefaultView` itself is untouched: the committed 2-26 upgrade command and the system-field filtering still rely on its current semantics. ## Tests - New manifest-sync integration test (first commit, TDD red then green): a single sync creating two objects and a MANY_TO_ONE / ONE_TO_MANY relation pair asserts each object's INDEX view has a visible view field for its relation, plus a control case adding the same relations to pre-existing objects in a second sync. - Unit spec: the test that locked in the noop now asserts a visible view field at the expected position for RELATION and MORPH_RELATION. - Verified locally: all 62 metadata-side-effect unit tests, the new integration spec, `successful-sync-application-workspace-migration` (4 snapshots), `relabel-onto-new-field-manifest-sync`, `create-one-field-metadata-relation`, plus twenty-server typecheck and lint.

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

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.
