Question

I’m using Doctrine with Codeigniter. So i write a library class for using them together. But i cant access entities (after creating them from db with reverse-engineering). Doctrine gives error: Fatal error: Uncaught exception ‘Doctrine\ORM\Mapping\MappingException’ with message ‘Class Actions is not a valid entity or mapped super class.’

I just add this code for this situation to library class and works everything right but speed is very low:

    $this->em->getConfiguration()
             ->setMetadataDriverImpl(
                new DatabaseDriver(
                        $this->em->getConnection()->getSchemaManager()
                )
    );

What can i do for this error? I generated entities from DB with this function:

    $cmf = new DisconnectedClassMetadataFactory();
    $cmf->setEntityManager($this->em);
    $metadata = $cmf->getAllMetadata();
    $generator = new EntityGenerator();

    $generator->setUpdateEntityIfExists(true);
    $generator->setGenerateStubMethods(true);
    $generator->setGenerateAnnotations(true);
    $generator->generate($metadata, APPPATH."models/entities");

My Action entity:

<?php



/**
 * Actions
 *
 * @Table(name="actions")
 * @Entity
 */
class Actions
{
    /**
     * @var integer $id
     *
     * @Column(name="id", type="integer", nullable=false)
     * @Id
     * @GeneratedValue(strategy="IDENTITY")
     */
    private $id;

    /**
     * @var string $name
     *
     * @Column(name="name", type="string", length=45, nullable=false)
     */
    public $name;

    /**
     * @var string $nameSafe
     *
     * @Column(name="name_safe", type="string", length=45, nullable=false)
     */
    public $nameSafe;


    /**
     * Get id
     *
     * @return integer $id
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set name
     *
     * @param string $name
     */
    public function setName($name)
    {
        $this->name = $name;
    }

    /**
     * Get name
     *
     * @return string $name
     */
    public function getName()
    {
        return $this->name;
    }

    /**
     * Set nameSafe
     *
     * @param string $nameSafe
     */
    public function setNameSafe($nameSafe)
    {
        $this->nameSafe = $nameSafe;
    }

    /**
     * Get nameSafe
     *
     * @return string $nameSafe
     */
    public function getNameSafe()
    {
        return $this->nameSafe;
    }
}
