# 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
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
