在Sonata Admin查询

Question

I'm using Sonata to make a backoffice and at configureFormFields, I want do a query to return some values. The query is well done and returns values when I use var_dump, but at the form I always get "Class does not exist". Can you help me?

Here is the code:

protected function configureFormFields(FormMapper $formMapper)
{
      /* @var $queryBuilder \Doctrine\ORM\QueryBuilder */
    $queryBuilder = $this->getModelManager()
            ->getEntityManager('EBCoreKernelBundle:Campaign\Campaign')
            ->createQueryBuilder();

    $queryBuilder->select('cmp.id, cmp.name')
                 ->from('EBCoreKernelBundle:Campaign\Campaign', 'cmp');

          /* @var $templateList Template[] */
    $templateList = $queryBuilder->getQuery()->execute();

         var_dump($templateList);

    $formMapper
        ->add('name','sonata_type_model',  array('required' => true, 'query' => $queryBuilder));


}

Answer 1

$entity = new \\Nnx\\AbpBundle\\Entity\\Truc();

$query = $this->modelManager->getEntityManager($entity)->createQuery('SELECT t FROM Nnx\\AbpBundle\\Entity\\Truc t ORDER BY t.lib ASC')->execute();

As documentation:

https://sonata-project.org/bundles/admin/master/doc/reference/form_types.html

query defaults to null. You can set this to a QueryBuilder instance in order to define a custom query for retrieving the available options.

So, let's give it a query builder:

        $queryBuilder = $this->getModelManager()
           ->getEntityManager(Category::class)
           ->createQueryBuilder('c')
           ->select('c')
           ->from('AppBundle:Category', 'c')
           ->orderBy('c.title', 'ASC')
        ;

        $formMapper->add('toto', ModelType::class, array(
           'query' => $queryBuilder
        ))
