## Summary `joinColumnName` on relation field settings is always derivable from the field name (and the target object name for morph relations). This PR stops reading it from settings anywhere in production code; the stored value is no longer used. The settings field is **not** removed from data yet — a follow-up can drop it once we are confident nothing depends on the stored value. ## Helpers The helpers are split by layer because frontend and backend hold morph relations differently: the frontend has a base name plus a `morphRelations[]` array, the backend has one row per target with the name already morph-resolved. | Helper | Layer | When to use | |---|---|---| | `computeRelationGqlFieldJoinColumnName` | Shared / frontend (`gqlField`) | Non-morph relation on the frontend. | | `computeMorphRelationGqlFieldName` | Shared / frontend (`gqlField`) | Need the per-target morph gqlField name (e.g. `targetCompany`). | | `computeMorphRelationGqlFieldJoinColumnName` | Shared / frontend (`gqlField`) | Per-target morph join column on the frontend. Prefer over the non-morph helper for any morph field — it forces the per-target inputs. | | `computeMorphOrRelationFieldJoinColumnName` | Backend (`FlatFieldMetadata.name`) | Any backend read or write — the flat name is already morph-resolved, so one helper covers both cases. | | `computeMorphRelationFlatFieldName` | Backend (`FlatFieldMetadata.name`) | **Mutation paths only** (create / update / object rename). Reads consume the stored `field.name` and never call this. | ## Test plan - [x] Typecheck and lint (front, server, shared) - [x] Existing unit tests pass - [ ] CI green

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 deploy
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.
