method

RelationshipsField.LiveValidate

Add a server check that provides feedback while this field is being edited.

Arguments

Argument	Type	Description
`value`	`LiveValidator[[]operation.ID]`	A non-nil callback returning validation messages, or an error if the check could not run. It receives unfinished form input and must be read-only.

A new field definition with this live validator appended. Keep the returned definition; the original field is unchanged.

RelationshipsField

LiveValidate preserves existing live checks. It does not register a save rule; use Validate separately to enforce the rule when saving.
