Subcategory Symfony3

Question

Mam problem z dodaniem sub kategorii w aplikacji Symfony 3.4.6

Przy próbie stworzenia kategorii dostaję bład: 

Could not determine access type for property "parent" in class "xxx\NewsBundle\Entity\Category".

<?php

namespace xxx\NewsBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;


/**
 * @ORM\Entity(repositoryClass="xxx\NewsBundle\Repository\CategoryRepository")
 * @ORM\Table(name="news_categories")
 */
class Category extends AbstractTaxonomy {
    
    /**
     * @ORM\OneToMany(
     *      targetEntity = "Post",
     *      mappedBy = "category"
     * )
     */
    protected $posts;
    
    
    /**
     * @ORM\ManyToMany(targetEntity="category", mappedBy="parent")
     */
    private $children;
    
    
    /**
     *
     * @ORM\ManyToMany(targetEntity="category", inversedBy="children")
     * @ORM\JoinTable(name="subCategory",
     *  joinColumns={@ORM\JoinColumn(name="category_id", referencedColumnName="id")},
     *  inverseJoinColumns={@ORM\JoinColumn(name="parent_id", referencedColumnName="id")}
     *     )
     */
    private $parent;
    
    
    /**
     * Constructor
     *
     * ArrayCollection
     */
    public function __construct()
    {
        $this->children = new ArrayCollection();
        $this->parent = new ArrayCollection();
    }
    
    

    /**
     * Add child
     *
     * @param \xxx\NewsBundle\Entity\category $child
     *
     * @return Category
     */
    public function addChild(\xxx\NewsBundle\Entity\category $child)
    {
        $this->children[] = $child;

        return $this;
    }

    /**
     * Remove child
     *
     * @param \xxx\NewsBundle\Entity\category $child

    public function removeChild(\xxx\NewsBundle\Entity\category $child)
    {
        $this->children->removeElement($child);
    }

    /**
     * Get children
     *
     * @return \Doctrine\Common\Collections\Collection
     */
    public function getChildren()
    {
        return $this->children;
    }

    /**
     * Add parent
     *
     * @param \xxx\NewsBundle\Entity\category $parent
     *
     * @return Category
     */
    public function addParent(\xxx\NewsBundle\Entity\category $parent)
    {
        $this->parent[] = $parent;

        return $this;
    }

    /**
     * Remove parent
     *
     * @param \xxx\NewsBundle\Entity\category $parent
     */
    public function removeParent(\xxx\NewsBundle\Entity\category $parent)
    {
        $this->parent->removeElement($parent);
    }

    /**

    public function getParent()
    {
        return $this->parent;
    }
}

<?php

    public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder
                ->add('name', TextType::class, array(

    }

    public function setDefaultOptions(OptionsResolverInterface $resolver) {
        $resolver->setDefaults(array(
            'data_class' => 'xxx\NewsBundle\Entity\AbstractTaxonomy'
        ));
    }

}

Dzięki, wszystko gra. Korzystałem z doctrine:generate:entities i myślałem ze add i set SF czyta tak samo

Rada na przyszłość. W Symfony dużo mechanizmów automatycznie próbuje się odnosić do pól wykorzystując ich nazwy PascalCasem z prefiksami: set, get, has, is, add, remove.
