WizardV2: validate uniqueness of name (HMS-3801)

[ezr-ondrej]

Fetches Bluepritnts with the same name as inputed and when there is already one in the database, fails the validation.

This is implemented by adding async validation to the StateValidatedInput, which is bit complex as we wanted to add debounce for that validation as well, so it doesn't fire too frequently.

[ezr-ondrej]

We're firing for every name change, which is bit unfortunate, but I didn't manage to make debounce work for this.

have you tried something like:

  const [debouncedBlueprintName, setDebouncedBlueprintName] = useState(blueprintName);

  useEffect(() => {
    const handler = setTimeout(() => {
      setDebouncedBlueprintName(blueprintName);
    }, 500); 
    return () => {
      clearTimeout(handler);
    };
  }, [blueprintName]);

  const { data: sameNameBlueprint, isFetching } = useGetBlueprintsQuery(
    { name: debouncedBlueprintName },
    { skip: debouncedBlueprintName.length < 2 }
  );

this is not a classic debounced function, but it uses the state update mechanism of react to achieve it

I haven't, I guess this would work, but it would be setting the name to the local state on top of the global one.
Tho I guess it's simpliest solution we have now.

[ezr-ondrej]

I've fixed this in new version, but unfortunatelly it requires the caller to provide a memoized function, so it's prone to mistakes.

[ezr-ondrej]

Actually #1949 might make it bit easier :)

[ezr-ondrej]

I've rebased this to use the new state validation :)

[ezr-ondrej]

We now have second validator prop, that allows for async validation, when provided, it waits for the async validation to finish to mark validation success.

Is this ready for review, @ezr-ondrej ?

Is this ready for review, @ezr-ondrej ?

Definitelly ready for review, but if we prefer to wait until we figure out the validation properly, we can do that as well :)

Heya! I guess we went with the "wait until we figure out the validation properly" plan? Added a "blocked" label, feel free to replace it with "ready for review" in case I guessed wrong 😅
