# UI capability flags: `isUIEditable` + `isUICreatable`
## Per-verb capability model
This PR replaces the negative `isUIReadOnly` metadata flag with
positive, per-verb capability flags (à la Salesforce
`createable`/`updateable`):
- **`isUIEditable: boolean`, default `true`** — rename of `isUIReadOnly`
with inverted polarity, on **both** `objectMetadata` and
`fieldMetadata`. It is one concept ("can the user edit this through the
generic UI?") at two altitudes, so it carries one name at both levels.
- **`isUICreatable: boolean`, default `true`** — new, **object-level
only** (fields have no create verb). When `false`, no generic UI
affordance to create a record of this object appears anywhere (table "+"
buttons, board column add, calendar add, relation-section "Add new",
record picker "Add new", command-menu create action and its keyboard
shortcut).
Both flags are **UI-affordance flags only**: the server does not block
create/edit mutations based on them, so the system, API, and workflows
continue to mutate these records freely. They are orthogonal statements
about the object's nature with no implication rule in the data model.
Because today's inline creation UX creates a blank record the user must
then edit, the frontend create predicate currently requires both
`isUICreatable` and effective editability.
There is no CREATE permission in `ObjectPermissions`; the frontend keeps
gating creation on `canUpdateObjectRecords` as a proxy, ANDed with the
new flags.
## Unified create predicate
All generic creation entry points now flow through one predicate,
`canCreateRecordsForObjectMetadataItem` (`isUICreatable` && not
`isSystem` && not effectively read-only, where effective read-only
covers `isUIEditable`, `isRemote`, and the `canUpdateObjectRecords`
proxy via `isObjectMetadataReadOnly`). This deletes the previously
hardcoded suppression lists:
- `isRecordTableCreateDisabled.ts` and its hardcoded
`WorkflowRun`/`WorkflowVersion` list — deleted; those objects (plus
`workspaceMember`) now declare `isUICreatable: false` in the standard
application instead.
- The hardcoded `workspaceMember` guard inside
`useAddNewRecordAndOpenSidePanel.ts` — deleted.
- The `CREATE_NEW_RECORD` command menu item's availability expression
now checks `objectMetadataItem.isUICreatable`, `isUIEditable`,
`isSystem`, and `isRemote`; a workspace upgrade command re-syncs the
expression in existing workspaces.
Component-local conditions (soft-delete filter active, layout
customization mode) stay in their components.
## GraphQL compatibility and removal plan
The schema delta versus main is **purely additive plus deprecations —
zero breaking changes**:
- `isUIReadOnly` remains on both the ObjectMetadata and FieldMetadata
GraphQL output types for **one release** as a deprecated field computed
as `!isUIEditable` (`deprecationReason: 'Use isUIEditable'`). The Twenty
frontend no longer queries it.
- `isUIReadOnly` also remains on the **input side** for one release
(`CreateFieldInput`, `UpdateFieldInput`, `FieldFilter`, `ObjectFilter`),
keeping the schema shape identical to main for those members. On create
it acts as a legacy alias mapped to `!isUIReadOnly` (`isUIEditable` wins
when both are provided); on update it is ignored, exactly as on main (it
was never an editable property). Filtering on the deprecated member
keeps working until the column is dropped at upgrade time; after that it
is a deprecated no-op surface kept only for schema compatibility.
**Removal plan for next release: drop `isUIReadOnly` from the output
DTOs (and resolvers' `@ResolveField`s), from the input/filter types,
from the create-input mapping, and the `@WasRemovedInUpgrade`-retained
entity columns and decorators.**
## ⚠️ Webhook / database-event payload shape change
The `database-event-payload` type in `twenty-shared` got a clean rename
(no alias): metadata snapshots in webhook and database-event payloads
now carry `isUIEditable` (and `isUICreatable` at object level) **instead
of** `isUIReadOnly`, with inverted polarity. Consumers of these payloads
that read `isUIReadOnly` must switch to `isUIEditable`.
## New manifest properties (app-developer DX)
Application developers can now set these flags in their app manifests
(purely additive — existing manifests and older `twenty-sdk` versions
are unaffected, defaults apply when omitted):
- `objects[].isUICreatable?: boolean` (default `true`)
- `objects[].isUIEditable?: boolean` (default `true`)
- `fields[].isUIEditable?: boolean` (default `true`)
The manifest converters previously hardcoded `isUIReadOnly: false`; they
now read the manifest values with `?? true` defaults. The types are
re-exported through `twenty-sdk` from `twenty-shared`.
## Migration & backfill
- One fast instance command: adds `isUIEditable` (NOT NULL default
`true`) on `core."objectMetadata"` and `core."fieldMetadata"`, backfills
`isUIEditable = false` exactly where `isUIReadOnly = true`, drops
`isUIReadOnly`, and adds `isUICreatable` (default `true`) on
`objectMetadata`. The `down` is the exact inverse. Uses `ADD/DROP COLUMN
IF (NOT) EXISTS`, matching the 2-12 drop-`isCustom` precedent. Verified
up and down in separate transactions against a dev database with exact
backfill counts.
- **Cross-version upgrade safety (multi-version self-hosted jumps):**
the upgrade sequence interleaves per version (instance → workspace
commands), so pre-2.13 workspace commands run **before** the 2.13 rename
when an old instance jumps several versions. Following the `isCustom`
precedent: `isUIEditable`/`isUICreatable` are marked
`@WasIntroducedInUpgrade` and `isUIReadOnly` stays on both entities as
`@WasRemovedInUpgrade`, so the upgrade-aware entity metadata adapter
hides the not-yet-existing columns (and keeps the legacy column live) at
pre-2.13 cursors. **No committed upgrade command outside the 2-13
directory is modified**: the old 1-21/2-8/2-9 commands keep their
original `isUIReadOnly: true` inputs, which still compile (entity
property retained, deprecated create-input alias mapped) and still
produce the correct legacy column writes pre-rename.
- A 2-13 workspace command (`sync-standard-ui-capability-flags`)
re-syncs `isUICreatable` **and** `isUIEditable` on standard objects and
`isUIEditable` on standard fields from the standard-application
definitions. This backfills `isUICreatable: false` on
`workflowRun`/`workflowVersion`/`workspaceMember` and heals fields
created mid-cross-upgrade by pre-2.13 commands (whose hidden
`isUIEditable` value cannot reach the insert). Both 2-13 sync commands
pass `isSystemBuild: true` — the flat metadata validator otherwise
rejects direct updates to system objects (verified against a
deliberately drifted dev database; the run is idempotent).
- A second 2-13 workspace command re-syncs the create-record command
availability expression.
## Testing
- Unit tests for `canCreateRecordsForObjectMetadataItem`
(flag/permission/system combinations) and for the manifest converters
(flags set / omitted → defaults).
- Full `upgrade --dry-run` boots the sequence (107 steps) and validates
the upgrade-aware decorator references; both 2-13 sync commands verified
end to end against real drift and re-run idempotently.
- Schema verified by live introspection after the input-alias restore:
all four input/filter members match main, output deprecations intact;
frontend metadata types and `twenty-client-sdk` schema regenerated from
the running server.
- Read-only-related and touched jest suites pass on both packages;
typecheck and lint pass on `twenty-server` and `twenty-front`.
