How to check if there are related records before deleting to show user friendly error
This can be achieved by using before lifecycle hook on DeleteAction. We can then call action->halt() or action->cancel() from inside of this lifecycle hook.
Example: Here we want to cancel the delete action and close the modal too if the category has subcategories.
Tables\Actions\DeleteAction::make() ->before(function (Tables\Actions\DeleteAction $action, Category $record) { if ($record->childrenCategories()->exists()) { Notification::make() ->danger() ->title('Failed to delete!') ->body('Category has subcategories.') ->persistent() ->send(); // This will halt and cancel the delete action modal. $action->cancel(); } }),
