在Doctrine中使用唯一ID设置为NULL创建的实体对象

Question

I have a User entity class, on which I used php bin/console doctrine:generate:entities the usual way. This class has a unique ID among its variables :

class User 
{
    /**
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     * @ORM\Column(type="integer")
     */
    private $id;
    (...)

Much to my surprise, when I call $user=new User(); in my code, the newly created object has its $id set to NULL. Given the annotations I gave, isn't Doctrine supposed to set it automatically ?

Sure, I am aware that I can add a setId method to my class, but I feel this is not the correct way to do things. Any advice appreciated.

Answer 1

Unique id will be set on $em->flush($user). i.e after inserting in table.

You can get more information in doctrine's documentation.
