On edit form, useUnique fetches currently edited record and prevents saving

[bjab]

What you were expecting:
What happened instead:
We have edit form, where one of fields has unique validator - in our case resource should have unique name.
We change one of other resource fields and try to save, but name field is marked as invalid as already existing, although it did not change.
I see, that query returns currently edited record and that's why it fails.

Other information:
I see two ways of solving this (in our case):

1. do not run validation if field did not change
2. somehow pass filter like id <> currentRecord.id, but I don't have idea, how to do it as json object
3. when checking server response, if it contains only one record and id matches current, then pass validation

Environment

• React-admin version: 4.12.1
• React version: 18.2.0
• Browser: chrome

Hi
https://stackblitz.com/edit/github-awixt5?file=src%2Ftags%2FTagEdit.tsx
I made tag names unique

Steps to reproduce:

1. go to tags and edit one of them
2. add FR entry
3. go to EN tab
4. click save

Validation will fail, even that EN name was not changed

Ah I see now. Good catch, thanks!
