# Introduction
Initially this PR was about introducing integration coverage for view
field v2 tests
But feature itself wasn't finished, so ended up in a TDD style
devlopment
## The new orchestrator
Orchestrator will organize each flat entity diffing inferring either
validation errors or actions sequentially.
A new builder has been introduced when extended requires to define flat
entity validation utils and action generation for `delete` `update`
`create` operations. It's highly typed using generics
## View field integration testing
Introduce coverage on failing basic tests cases for view field
operations, successfull create is also covered. We could still add more
coverage, will be done later in following PRs
## Remaining tasks for upcoming PRs:
- [ ] rename builder methods names to add generate action in their names
- [x] refactor view validation to handle field and view uniqueness index
combination
- [ ] implem strict update validator on view and view field
- [ ] dynamic cache invalidation post run
- [ ] Add coverage to successful and failing view field operations
- [ ] error formatting summary computation
- [ ] extract types out of the workspace entity builder
## Some vision
Currently flat field metadata maps is nested in the flat object metadata
maps, making its build nested too. ( not extending the new generic
builder )
We will refactor this part for both to be stored extra flat such as the
other existing flat entities.
It will require a small refactor to the generic builder that will not
only have impact on the currently built flat entity optimistic cache but
to an other one ( for example when building a create object action it
will also have an impact flat field maps )
