@ORM\PrePersist is not allowed to be declared on property

Question

i have been learning zend framework for the past days now. I have encountered this error when i tried to run the site:

Annotation @ORM\PrePersist is not allowed to be declared on property Post\Entity\Post::$alterado. You may only use this annotation on these code elements: METHOD.

heres my Post.php file:

 <?php

 namespace Post\Entity;

 use Application\Entity\AbstractEntity;
 use Doctrine\ORM\Mapping as ORM;

 /**

Am i missing any "use" statement on the file?

Any help is apreciated, thank you for your atention :)

Answer 1

I fixed it, i should have call @ORM\PrePersist and @ORM\PosUpdate on the method. :)
