Félix Malfait 3ad3e8bd1a feat: kanban, calendar and group-by table layouts for dashboard view widgets (#22963)
## Context

Dashboard view widgets previously only rendered flat tables. This PR
ships the full feature: **Table with group-by**, **Kanban**, and
**Calendar** layouts for dashboard view widgets — server API + frontend,
end-to-end. (Originally staged as a 4-PR stack — #22966, #22967, #22968
— consolidated here per review.)

## Server / API

- **View typing.** Adds `KANBAN_WIDGET` and `CALENDAR_WIDGET` to
`ViewType` (following the `TABLE_WIDGET` precedent) so widget-backing
views keep their layout in `view.type` while staying excluded from
record-index pickers. Shared `getViewLayoutFromViewType()` maps widget
types to their base layout; `isWidgetViewType()` centralizes the
exclusions that were previously hardcoded per-site.
- **Migrations.** Two fast instance commands (**2.23**): `ALTER TYPE
core.view_type_enum ADD VALUE` for both values, and a widened
`CHK_VIEW_CALENDAR_INTEGRITY` constraint covering `CALENDAR_WIDGET`
(entity `@Check` updated for fresh installs).
- **Validation.** `FlatViewValidatorService` keys kanban/calendar
validation on the mapped layout, so widget views get the same invariants
as index views (kanban needs a groupable group-by field; calendar needs
a date field + layout). Calendar widget views default to month; a
non-month (DAY/WEEK) layout is rejected at the API level **unless** the
`IS_CALENDAR_WEEK_VIEW_ENABLED` feature flag is enabled for the
workspace — the same flag that gates day/week on index calendars.
- **API.** `upsertViewWidget` (LAYOUTS permission) accepts a nested
`view` settings input (`type`, `mainGroupByFieldMetadataId`,
`shouldHideEmptyGroups`, kanban aggregate/column-width, calendar
layout/fields). Routes through the standard update path, so `viewGroups`
auto-generate from SELECT options exactly like index views. Only widget
view types accepted; only `RECORD_TABLE` widgets can change view
settings.
- **AI tools.** `create-complete-dashboard` + `create_view` now
use/allow the `*_WIDGET` types (previously they created plain `TABLE`
views that leak into index pickers).

## Frontend

**Settings panel.** The **Source** (object) row comes first, since which
layouts are available depends on it. The **Layout** row below is a
working dropdown (Table / Kanban / Calendar); layouts the source object
can't support are **disabled with a hint** ("Needs a Select field" /
"Needs a Date field") rather than hidden. Group-by row (select fields;
searchable) with a **Hide empty groups** toggle while grouped; **Date
field** row replaces Group by while Calendar is active, and — when the
`IS_CALENDAR_WEEK_VIEW_ENABLED` flag is on — a **Calendar view** row
(Day / Week / Month) appears beside it; **Limit** row hidden while
grouped (only the flat virtualized loader enforces it). Kanban keeps its
group-by locked (no `None` option).

**Instant edit-mode preview.** Draft snapshots carry `viewGroups`;
picking a group-by synthesizes them client-side
(`buildDraftViewGroupsForFieldMetadataItem`, mirroring the server's
generation), so grouped tables/boards preview immediately before
dashboard save. On save, `upsertViewWidget` responses hand back the
server-generated groups, which replace the client-generated ones in the
persisted snapshot.

**Renderers.** `RecordTableWidgetRendererContent` branches on the
backing view's layout: `RecordBoardWidget` (wraps the standard
`RecordBoardContainer`) and `RecordCalendarWidget` (mounts the existing
`RecordCalendar`, which renders month / day / week) inside the same
per-widget provider sandbox the table uses.

**Read-only semantics.** Two flags with distinct scopes, each documented
on its state:
- `isRecordBoardViewSettingsReadOnlyComponentState` — locks the board
chrome that edits view settings (add group, column reorder/resize/menu,
aggregates); **card drag still updates records** under object
permissions.
- `isRecordCalendarReadOnlyComponentState` — widget calendars are
read-only by default (no drag, no add-new, no in-calendar layout
switch); cards open the side panel. The one exception, behind
`IS_CALENDAR_WEEK_VIEW_ENABLED`: a **live (non edit-mode) day/week**
widget calendar allows drag-to-reschedule and record creation under
object permissions. Month calendars and edit-mode previews stay
read-only.

**Calendar state componentization.** The calendar module's three
settings move from global atoms to component states keyed on
`RecordCalendarComponentInstanceContext` (same pattern as record-board),
so several calendar widgets and an index-page calendar can coexist
without leaking state. All readers resolve the ambient instance;
calendar unit tests updated.

**Multi-instance fixes that also fix index pages:** record drag states
were written against a different instance than every reader resolves
(now use the ambient instance); the board sticky-header DOM id is
namespaced per board; dragged board cards portal to `document.body`
while dragging so react-grid-layout's transforms can't offset
the clone from the pointer.

## Scope (v1)

- Widget calendars are month-only and read-only by default. With
`IS_CALENDAR_WEEK_VIEW_ENABLED` enabled, day/week layouts become
selectable (UI + API) and live day/week widget calendars support
drag-to-reschedule and record creation under object permissions.
- Widget group-by offers SELECT fields only (server auto-generates
groups from options; widgets have no per-record add-group flow).

## Tests

- Integration: `upsert-view-widget-view-settings.integration-spec.ts` (9
tests — group auto-creation, invalid type/field rejections, non-month
calendar widget rejected while the week/day flag is off and accepted
once it's enabled, combined settings+fields call); pre-existing
`upsert-view-widget` suite (20) green.
- Front: new suites for draft view-group generation and snapshot
clone/build utils; calendar suites componentized; full `twenty-front`
jest, typecheck, oxlint green; `twenty-server` typecheck + lint green.
- Browser-verified end-to-end (real dev server + seeded workspace):
configure → live edit-mode preview → save → reload for all three
layouts; measured drag with pointer inside the card; index-page calendar
re-verified (with the week/day flag enabled).

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
