Displaying data from doctrine in twig for loop

Question

Controller code:

    $em = $this->getEntityManager();

    $books = $em->getRepository('Books\Model\Books')->findAll();

    return $this->render('Books/View/list.html.twig', array(
        'books' => $books
    ));

Twig template code:

{% extends 'Books/View/layout.html.twig' %}

{% block content %}
<table>
   <tr>
        <th>Name</th>
        <th>Description</th>
   </tr>
   {% for row in books %}
       <tr>
           <td>{{ row.name }}</td>
           <td>{{ row.description }}</td>
       </tr>
   {% endfor %}
</table>
{% endblock %}

I don't know why I don't see nothing in cell's designed for name and description. When I open developer console and look into html tree I see this cell's but empty..

When I open developer console and look into html tree I see this cell's but empty.. - I mean: I see 'td' tags but without data — mr.I_dont_know

I think the fact that you see tds implies that the query was successful and it is actually iterating over books. Are you sure the property names are correct? I would try dumping books to verify what's really there. — Don't Panic

As far as I remember You need to create getters:

class Books
{
    /** @Id @Column(type="integer") @GeneratedValue */
    private $id;

    /** @Column(type="string") */
    private $name;

    /** @Column(type="string") */
    private $description;

    public function getName() { return $this->name; }
    public function getDescription() { return $this->description; }
}

Just read manual 7. Working with Objects

You might prefer to read markdown documentation Doctrine1 Documentation. I am writing md files myself so prefer to read them too.
