nuxt ui form validation, zod, validate only specific field not whole form
Hi I have a nuxt ui form using zod error validation, one of my fields is a cloudflare turnstile token which is validated to ensure it's not empty. however once the error appears if i complete the turnstile challenge the zod error wouldn't disappear until resubmitting the form. so I added a watcher to check when the turnstile token isn't empty to validate the specific field in order to clear the error. however this seemingly triggers my whole form validation. should this work or is there another way to do this? as currently my watcher when i load my form will trigger this on initial load which in turn shows errors on all my inputs that weren't filled in

Hi @WiFi Plug. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
The Nuxt UI Form component exposes a validate method that can be called with options, including a name (field) to validate only a specific field. According to the documentation, the method signature is:
So, calling:
should validate only the cfTurnstileToken field, not the whole form. However, your code:
does not match the documented API, which expects an options object, not positional arguments. This could be why the whole form is being validated instead of just the field you want.
Correct usage:
This should only validate the cfTurnstileToken field and clear its error when the value becomes valid, without triggering validation for the rest of the form fields. If you still see all errors on initial load, ensure your watcher is not running before the form is ready or before the field has a value, as triggering validation on an empty field will naturally show its error.
For more details, see the "Expose" section of the Nuxt UI Form docs, which describes the validate method and its options in detail: Form Expose API.
If you continue to see all errors, double-check your watcher logic and when it triggers, as well as the initial state of your form fields. The documentation does not mention any caveats with field-level validation using the validate method as described above.

@kapa.ai and clearing a specific fields error
Let me check the knowledge base for you again. One moment! :books:
----------------------
To clear a specific field's error in a Nuxt UI Form, you can use the clear method exposed by the form component reference. The method signature is:
If you provide the field name (e.g., 'cfTurnstileToken'), it will clear errors associated with that specific field. For example:
This will clear only the error for the cfTurnstileToken field, leaving other field errors untouched. If you call clear() without arguments, it will clear all form errors Form Expose API.
