Question

I have a View entity that references an associated entity called ViewVersion . But if I name the variable anything other than viewVersion , eg just simple version , then I get an error:

Neither the property "viewVersion" nor one of the methods "getViewVersion()", "isViewVersion()", "hasViewVersion()", "__get()" exist and have public access in class "Gutensite\CmsBundle\Entity\View\View".

All the getters and setters are created through php app/console doctrine:generate:entities but they are for getVersion() and not getViewVersion() .

Question: So, is there some unspoken rule that associated entities MUST be named the same as their class name?

Entity Definition

/**
* @ORM\Entity
* @ORM\Table(name="view")
* @ORM\Entity(repositoryClass="Gutensite\CmsBundle\Entity\View\ViewRepository")
*/
class View extends Entity\Base {

    /**
    * @ORM\OneToOne(targetEntity="\Gutensite\CmsBundle\Entity\View\ViewVersion", inversedBy="view", cascade={"persist", "remove"}, orphanRemoval=true)
    * @ORM\JoinColumn(name="versionId", referencedColumnName="id")
    */
    protected $version;

    /**
     * @ORM\Column(type="integer", nullable=true)
     */
    protected $versionId = NULL;
}

FYI, the variables for associated entities can be whatever you want.

This was caused by a predefined formType still referencing "viewVersion". The first variable in a form $builder->add() is a reference to the specific variable in the entity. I had viewVersion listed there still, and when I audited my code, I assumed it was just a generic reference (without any requirement) or possibly a reference to the Entity class, so I didn't change it:

$builder->add('viewVersion', new ViewVersionType(), array(
    'label' => false
));

The SOLUTION to this problem was to change viewVersion to version so that it references an actual variable on the entity. Obviously...

$builder->add('version', new ViewVersionType(), array(
    'label' => false
));
