and have : php app/console doctrine:schema:update --force

php app/console doctrine:schema:update --force

[Doctrine\Common\Annotations\AnnotationException]
[Semantical Error] The annotation "@Doctrine\ORM\Mapping" in property Miejsce\ObiektyBundle\Entity\Adres::$user does not e
xist, or could not be auto-loaded.
So where i can have error ?

error was in syntax - i have @ORM/OneToOne but need @ORM\OneToOne now work fine ! :)

回答1:

I'm not sure if I understand exactly what you are asking, but your annotations are not setup correctly.

/**
 * @Entity

should become

/**
 * @ORM\Entity

And

/**
 * @Id @Column...

should become

/**
 * @ORM\Id
 * @ORM\Column...

Same for @OneToOne should be @ORM\OneToOne

Basically you are not prefixing your annotations correctly. You have use Doctrine\ORM\Mapping as ORM; but you aren't using it properly. Prefix your annotations and that will get you going.

回答2:

The answer is in the error message. Look at what is different between your two classes.

/**
 * @Entity
 */

Vs:

/**
 * @ORM\Entity
 */

So update the one that is giving you the error.

edit

When you import Doctrine's annotations with use Doctrine\ORM\Mapping as ORM;, you'll need to start all those annotations with @ORM\. The annotation-reader will know that @ORM\Entity will actually mean @Doctrine\ORM\Mapping\Entity, which is the class that defines that annotation.
