UniqueObject validator - field issue

[imonteiro]

Hi,

I'm using UniqueObject validator but I receive this error:

Expected context to contain id

In my fieldset definition, I have this:

public function getInputFilterSpecification()
{
    return array(
        'identifier' => array(
            'required' => true,
            'validators' => array(
                array(
                    'name' => 'DoctrineModule\Validator\UniqueObject',
                    'options' => array(
                        'object_manager' => $this->objectManager,
                        'object_repository' => $this->objectManager->getRepository('Project\Entity\Project'),
                        'fields' => 'identifier',
                        'messages' => array(
                            'objectNotUnique' => 'Sorry, a project with this identifier already exists !',
                        )
                    )
                ),
            ),
        ),
        'name' => array(
            'required' => true
        ),
        'description' => array(
            'required' => true
        ),
    );
}

My table have id primary key and identifier is a unique field (string).

This only works on primary keys? (if I set 'fields' => 'id', I don't receive the error).
What I'm missing?

Thanks in advance.

The problem here is that we actually use the $context parameter passed to isValid (which is wrong, IMO).

Yes, your compared fields should be the same ones reported in the fields option of the validator.

Dupe of #377

I had the same error in 2023.
The solution is to include the "id" field of the entity as the form element in the form class as a hidden field.

$this->add([
    'name' => 'id',
    'type' => Element\Hidden::class
]);
