# Introduction
As discussed with Charles we will introduce a new command to convert
seeded twenty instance into `flatObjectMetadatas` `flatFieldMetadatas`
mocks but later.
We can think of this PR as a partial freeze of this command result run
even tho the template might not be strictly the same in the end.
For the moment we only extracted few objects with their fields in order
to start testing newly introduced tools
used scripts ( not committed and written on the fly ):

# Introduction
The workspace migration runner v2 now computes the next
flatObjectMetadataMaps post current ws migration action has been run
So the following one have an up to date informations
## Still TODO
~~Remove any contextual information from workspace migration v2 and
consume the optimistic cache to retrieve them~~
## Next steps
- Create flat-object-metadata-maps testing toolbox and flat-object/field
testing toolbox
- Implement strong coverage on every created utils/transpiler and
applyWorkspaceMigrationAction method
# Introduction
- Retrieveing flat-object-metadata-maps for input transpilation, we
decided not to introduce map merge for remaining validation operation
for the moment
- Refactored the field metadata service v2 to sequentially
optimistically render on each iteration
# Introduction
- deferrable constraint on foreignKey definition
- fix relation creation input transpilation to flat field metadata
- fix validation to allow contextual validation on not already created
field metadata ( usefull for relation, and will be necessary for the
import )
# Introduction
The cache is not accurately typed regarding the `fieldMetadataMaps` they
do not contain relations
In this way we:
- Created dedicated transpilation tools for cache manipulation
- Avoided recursivity in transpilation tools
- Fix and finalized the createMany fields metadata service v2
- Refactor the validator to handle validation :)
## What's next:
- Implem integration tests to make things run 🙃
- migrate existing settings valdiation
- Finish the create object metadata service
- Handle update input transpilation and validation
# Introduction
- FlatFieldMetadataType validators hashmap
- Do not fail fast on validation but aggregate errors
- Implemented `enum` validation
- Plugged the new v2 dynamic call in the field metadata service v2
## What's next:
- Implem integration tests to make things run 🙃
- migrate existing settings valdiation
- Finish the create object metadata service
- Handle update input transpilation and validation
## Open question
Should we implement, not covered validation ?, adding strictness now or
never.
This will be required by the import anw
## Discovered issue with cache
Currently the cache is not accurately typed, `fieldsById` map are not
storing any relations.
Which means the current transpilation tools are hitting undefined at
runtime
In the best of the world we will refactor the cache to be storing
`FlatObjectMetadata` and `FlatFieldMetadata` so we don't even have to
transpile them for validation and so on
But it would require to refactor the loaders that returns the cache to
the front on hit as FieldMetadataEntity, so we might land on a lighter
solution to rather add a new `getExistingFlatCache` that handles the
transpilation itself
About to do that in an other PR to be discussed with Coco
# Introduction
Following https://github.com/twentyhq/twenty/pull/13420
What has been done:
- `CreateFieldInput` transpilation to `FlatFieldMetadata`
- `FlatFieldMetadata` validator service
- A lof of transpilation utils from `input` to `flatObject` or
`flatField`
- Created dedicated v2 api metadata services
- Introducing `inferDeletionFromMissingObjectFieldIndex` in the builder,
to avoid diffing every object and field of the current workspace we
allow only generating create/update migration operations, usefull when
passing by the api metadata
## We still need to in another PR:
- Implement a strong unit test coverage and critical functions and
services
- Finalize flat field metadata validation exception for `options`
`defaultValue` `settings` and `relations`
- Finalize `flatObjectMetadata` validation and v2 service refactor
- Plug the new service when feature flag is enabled
# 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
