[FLOW3-general] problem while setting up the SetupController in blog tutorial

[Streitferd Erika]

Hello!

Another issue I have met on blog tutorial.
I am trying to set up my SetupController , so I modified the Classes/Controller/SetupController.php like in the tutorial, but when I try to access the controller on this link: http://localhost/blog/Web/index.php/TYPO3.Blog/Setup I got an error: 

#42S22: SQLSTATE[42S22]: Column not found: 1054 Unknown column 't0_.title' in 'field list' (More information)

PDOException thrown in file
C:\xampp\htdocs\blog\Packages\Framework\Doctrine.DBAL\Classes\Connection.php in line 633.

Go to the FORGE issue tracker and report the issue - if you think it is a bug!
My \Classes\Domain\Model\Blog.php file looks like this:
class Blog {

    /**
     * The title
     * @var string
     * @FLOW3\Validate(type="Text")
     * @FLOW3\Validate(type="StringLength", options={ "minimum"=1, "maximum"=80 })
     * @ORM\Column(length=80)
     */
    protected $title;

    /**
     * The description
     * @var string
     * @FLOW3\Validate(type="Text")
     * @FLOW3\Validate(type="StringLength", options={ "maximum"=150 })
     * @ORM\Column(length=150)
     */
    protected $description;

    /**

    protected $posts;
    
    public function __construct() {
        $this->posts = new \Doctrine\Common\Collections\ArrayCollection();
    }
    
    /**

     */
    public function addPost(\TYPO3\Blog\Domain\Model\Post $post) {
        $post->setBlog($this);

    public function removePost(\TYPO3\Blog\Domain\Model\Post $post) {
        $this->posts->removeElement($post);
    }


    /**

    public function getTitle() {
        return $this->title;
    }

        $this->title = $title;
    }
