Question

I got this exception “… EntityCategoryProxy could not be converted to int in …” when I wanted to make such loop in my TWIG template:

{% for category in categories %}     
{{category.name}}
     {% for fund in funds %}
        {% if fund.category == category.id %} <<<<<<< EXCEPTION LINE
            {{fund.fundName}}
        {% endif %}
    {% endfor %}
{% endfor %}

WORKING CATEGORY RETRIEVAL (after accepted ANSWER change)

    $repository2 = $this->getDoctrine()
        ->getRepository('ToolsTFIBundle:Category');
    $query2 = $repository2->createQueryBuilder('c')
        ->orderBy('c.name','ASC')
        ->getQuery();
    $categoryList = $query2->getResult();

ALSO WORKING CATEGORY RETRIEVAL (after accepted ANSWER change)

    $em = $this->getDoctrine();
    $categoryList = $em->getRepository( 'ToolsTFIBundle:Category' )
                                    ->findAll();

“fund.category” is foreign key mapped to “category.id” via Doctrine2 ORM. Is there any option to make this loop valid and working?

Answer 1

fund.category is not comparable with category.id because fund.category is an entity.

Use fund.category.id == category.id
