Warning: spl_object_hash() expects parameter 1 to be object, integer given in /var/ww

[Dundee]

No obstante ese problema parece estar ya resuelto al haber cambiado el tipo de dato a "entity" , pero ahora al guardar los datos en la db tengo un nuevo problema , porque los intenta guardar como null.

Para evitar más confusiones voy a pegar el código (con motivo de aprender buenas prácticas, he creado el form en una clase aparte para poder reutilizarlo cuando lo necesite).

Error:

Código:

An exception occurred while executing 'INSERT INTO Book (phrase, creator_uid, parent_branch) VALUES (?, ?, ?)' with params [null, null, null]:

SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'creator_uid' cannot be null

Y por último la famosa clase
NewPhrase.php

Código:

<?php

use Symfony\Component\Form\AbstractType;

    {
        $builder
            ->add('phrase', 'text', array('label'  => 'My phrase', 'max_length' => 500))
            ->add('parentBranch', 'entity', array(
            'class' => 'BookMainBundle:Book',
            ))

            ->add('creatorUid', 'integer')
            ->add('save', 'submit');
    }
 
    // unique identifier for this form.
    public function getName()
    {
        return 'phrase';
    }
}
