# Introduction
In this PR we're migrating both the `field` and `object` metadata to be
using the new `FlatEntityFromV2` that requires all the
`UniversalFlatEntityExtraProperties` to be spread at the flat entity
root.
This means that we have to update all of their flat declaration
This type swap allows to isole a specific entity migration into his own
type scope and avoid to have everything handled at once
```ts
/**
* Currently under migration but aims to replace FlatEntity afterwards
*/
export type FlatEntityFromV2<
TEntity,
TMetadataName extends AllMetadataName | undefined = undefined,
TInnerFlatEntity extends { __universal?: unknown } = FlatEntityFrom<
TEntity,
TMetadataName
>,
> = Omit<TInnerFlatEntity, '__universal'> & TInnerFlatEntity['__universal'];
```
## Impact
Both object and field:
- Create input transpilation utils
- from entity to flat tools
- mocks
## Note
Removed from the universal extra properties the jsonb properties that do
not contain a serialized
## Next
Next step is to incrementally make the builder and runner expect
`UniversalFlatEntity` for both of these metadata
This way we will be able to fully migrate an entity e2e typesafely
# Introduction
In this PR we're refactoring the `FlatEntity` type to become a superset
of the `UniversalFlatEntity`.
Right now we're storing all the extra properties in `__universal`
property, at some point it might just be sibling to other entity and we
might rely on the `propertiesToCompare` constants and TypeScript
allowing passing a superset type into a smaller subset type
## FromTo utils
The entity to flat entity method now computes the universal information,
standardized a typing and pattern to do
## Example
Also strictly type

# Introduction
Currently refactoring `flatEntity` typing, encountering some tsc errors
due to this fk aggregator custom override
It shall now follow generic pattern leading to be named `fieldIds`
Needs to flush object cache when released
# Introduction
following https://github.com/twentyhq/twenty/pull/17279
As we've finally identified all the syncable metadata entities, which
means they're expected to have non nullable applicationId and
universalIdentifier at pg_level we can remove previous retro comp
universalIdentifier fallbacking and update the dto too
~~This needs IdentifyRemainingEntitiesMetadataCommand and
MakeRemainingEntitiesUniversalIdentifierAndApplicationIdNotNullableMigrationCommand
to be run~~
```ts
[Nest] 197 - 01/21/2026, 3:08:35 PM LOG [MakeRemainingEntitiesUniversalIdentifierAndApplicationIdNotNullableMigrationCommand] Successfully run MakeRemainingEntitiesUniversalIdentifierAndApplicationIdNotNullableMigrationCommand
```
# Introduction
Followup https://github.com/twentyhq/twenty/pull/16981
1/ Migration, applicationId and universalIdentifier are required on
entity ( save point migration + upgrade command fallback pattern )
2/ Backfill using previous standard ids
# Introduction
As we introduced a new grain on relation extraction thanks to low level
`SyncableEntity` and `WorkspaceRelatedEntity` we're able to strictly
typesafe extract metadata entity
The new constant centralizes both many to one and one to many constants
metadata entity constants in a more strictly typesafe way. Remains only
the flatEntityForeignKey aggregator which has to be chosen manually
across all available targeted flat entity ids properties
# Introduction
Added a `WorkspaceRelated` and `AllNonWorkspaceRelatedEntity` to
simplify the `FlatEntityFrom` that now do not expect a string literal to
omit and itself builds the related many to one entities foreign key
aggregators
We now have the type grain over relation to syncable or just workspace
related entities
Added a migrations that sets the fk on missing entities
## Next
In upcoming PR we will be able to introduce such below type
```ts
import { type CastRecordTypeOrmDatePropertiesToString } from 'src/engine/metadata-modules/flat-entity/types/cast-record-typeorm-date-properties-to-string.type';
import { type ExtractEntityManyToOneEntityRelationProperties } from 'src/engine/metadata-modules/flat-entity/types/extract-entity-many-to-one-entity-relation-properties.type';
import { type ExtractEntityOneToManyEntityRelationProperties } from 'src/engine/metadata-modules/flat-entity/types/extract-entity-one-to-many-entity-relation-properties.type';
import { type ExtractEntityRelatedEntityProperties } from 'src/engine/metadata-modules/flat-entity/types/extract-entity-related-entity-properties.type';
import { type RemoveSuffix } from 'src/engine/workspace-manager/workspace-migration-v2/workspace-migration-builder-v2/types/remove-suffix.type';
import { type SyncableEntity } from 'src/engine/workspace-manager/workspace-sync/types/syncable-entity.interface';
export type UniversalFlatEntityFrom<TEntity extends SyncableEntity> = Omit<
TEntity,
| `${ExtractEntityManyToOneEntityRelationProperties<TEntity> & string}Id`
| ExtractEntityRelatedEntityProperties<TEntity>
| 'application'
| 'workspaceId'
| 'applicationId'
| keyof CastRecordTypeOrmDatePropertiesToString<TEntity>
> &
CastRecordTypeOrmDatePropertiesToString<TEntity> & {
[P in ExtractEntityManyToOneEntityRelationProperties<TEntity> &
string as `${RemoveSuffix<P, 's'>}UniversalIdentifier`]: string;
} & {
[P in ExtractEntityOneToManyEntityRelationProperties<
TEntity,
SyncableEntity
> &
string as `${RemoveSuffix<P, 's'>}UniversalIdentifiers`]: string[];
};
```
Changes:
- as we store date in redis as serialized, let's make all flatEntity
dates as string. This requires changing FlatEntity types and making sure
that entity are converted to flatEntity and flatEntity to dtos
# Introduction
Initial motivation here was to migrate the object related records logic
from v1 to v2, please note that now in v2 views aren't records anymore
but core engine entities
## What's done
- Added specific label identifier targeting view field logic
- Handled side effects on viewField creation with lowest position on
object label identifier mutation
- Added viewField relations in field metadate entity + handled
optimistic in builder v2
- Added view relations in object metadata entity + handled optimistic in
builder v2
- Added integration tests covering the side effects and new validation
exceptions
- Sandardized cache computation
- Coverage on object metadata creation side effect on views and view
fields
## Coverage
```ts
PASS test/integration/graphql/suites/view/view-field/object-identifier-update-side-effect-on-view-field.integration-spec.ts
View Field Resolver - Successful object metadata identifier update side effect on view field
✓ should create a view field on label identifier object metadata update if it does not exist on view (7 ms)
✓ Should not allow deleting a label identifier view field (17 ms)
✓ Should not allow destroying a label identifier view field (6 ms)
✓ Should not allow updating a label identifier view field visibility to false (8 ms)
✓ Should not allow creating a view field with a position lower than the label idenfitier view field (180 ms)
✓ Should not allow updated labelIdentifier view field with a position higher than existing other view field (346 ms)
✓ Should allow updated labelIdentifier view field with a position higher than existing other view field (434 ms)

# Introduction
Extracting the legacy fields build and dispatch out of the object one to
follow the generic flat entity build, also update caches entries for
object
## Main tasks
- flat field map cache
- flat field builder
- refactored the dispatch matrix to return flat entity maps instead of
flat entity arrays
- orchestrator aggregator
- removing legacy code
- making universal identifier aka standardId of standard field for
custom object deterministically dynamic
- perfs debug logs for v2
## TODO
- [x] Refactor the generic entity builder to be dependency flat maps in
order to main foreign keys list in flat parent
- [x] Refactor the flat object metadata to contain the array of related
fields and avoid costy find object fields
- [ ] Improve the create field handler to handle multiple field at once
- [ ] Refactor the dispatch to embbed the comparison
- [ ] Improve perf by extracting from elements out of existing
- [ ] Fix the labelIdentifierId validators on object before field
creation ( integ tests are in failing mode )
## Debug logs snippet

```
As you can see cache invalidation is way to long, we could replace the
cache by the optimistic in the end
# Introduction
Honestly this implem is a mess, discussing a potential side effect
handler with @weiko before the build and run that would handle each side
effect per entity and operation
Handling:
- [ ] unique index is generated when a field is updated with the
`isUnique`
- [x] an index is generated when a relation is created
- [x] search vector index creation on custom object creation
- [x] renaming a field metadata or an object should re-create all
related indexes which are composed by their namings
- [x] delete object should remove any related indexes
- [x] delete field should update related indexes ( if index ends up
empty it should be removed )
- [ ] on object renaming that contains morph fields -> triggers update
field -> trigger index recompute
- [x] on update name renaming should recompute all related indexes
## TODO
- [x] Integration testing
- [ ] Refactor the index maps cache to be storing a
`idsByObjectMetadataId`
- [x] Refactor deterministic name to use order sorting
- [x] Remove flat index from flat object
## What's next
Will handle morph indexes in a new dedicated PR for the moment will
stick to this
Same for the cache improvement and uniqueness
# Introduction
In this PR we create basic transpilation methods and utils to handle
input to flat, entity to flat, object maps to flat. In order to
transpile everything into a common validation that will be implemented
in another PR
## FieldMetadataEntity typing
Added `never | null` to fields that should never be in order to ease
general abstracted method to pass null, as anw it's what is in the
database
## Todo
- ~~Create a feature flag~~
- Integration test for object creation through metadata api + pg col
introspection and snapshoting
