Symfony3无法访问字符串变量（“Margherita”）上的属性（“small_pizza”）

Question

I trying to display price, but occurs error Impossible to access an attribute ("small_pizza") on a string variable ("Margherita").

This is my Controller:

/**
     * @Route(
     *      "/menu",
     *      name = "pizza_menu"
     * )
     * 
     * @Template
     */
    public function menuAction() {

        $Repo = $this->getDoctrine()->getRepository('PizzaBundle:Menu');
        $rows = $Repo->findAll();

        return array(
            'rows' => $rows
        );
    }

And this is my database: enter image description here

In a Twig code is this:

{% for entry in rows %}
   <tr>
      <td>{{ entry.id }}</td>
      <td>{{ entry.name }}</td>
      <td>{{ entry.components }}</td>
      <td>
          <ul>
              <li>{{ entry.name.small_pizza }}</li>
              <li>{{ entry.name.small_pizza }}</li>
              <li>{{ entry.name.small_pizza }}</li>
              <li>{{ entry.name.small_pizza }}</li>

          </ul>
      </td>
  </tr>

Help me please :)

Answer 1

Try accessing to the prince entity navigating the relations so try this:

<li>{{ entry.price.small_pizza }}</li>

instead of

<li>{{ entry.name.small_pizza }}</li>

Hope this help
