Symfony - 无法确定属性“id”的访问类型

Question

I get this error:

Could not determine access type for property "id"

Then I read on the internet that I need to add a set function for id. But that only led to other errors.

Answer 1

Remove name="id" , or try this construction for you id field.

/**
 * @ORM\Column(type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;

Answer 2

Something like this

/**
 * Fake
 *
 * @see fabien good guy
 */
public function setId($id) {}
