如何在symfony2中调用表单类型的实体库函数

我想调用表单类型类中的函数。函数生成数组，并在实体存储库类中编写。使用该数组，我将生成动态表单字段。 下面是实体存储库类函数

public static $roleNameMap = array(
            self::ROLE_SUPER_ADMIN => 'superAdmin',
            self::ROLE_MANAGEMEN => 'management',
            self::ROLE_MANAGERS => 'manager',
            self::ROLE_IT_STAFF => 'itStaff',
            self::ROLE_CS_CUSTOMER => 'csCustomer',
            self::ROLE_CS => 'cs',
            self::ROLE_DEALER => 'dealer',
            self::ROLE_ACCOUNT_STAFF => 'accountStaff',
            self::ROLE_BROKER_USER => 'staff',
    );

    public function getGroupListArray()
        {
            $qb = $this->createQueryBuilder('g')
                ->orderBy('g.hierarchy','ASC');
            $query = $qb->getQuery();
            $groupList = $query->execute();
            $roleNameMap = array();
            foreach ($groupList as $role){
                $roleNameMap[$role->getId()] = $role->getRole();
            }

            return $roleNameMap;
        }

public function buildForm(FormBuilderInterface $builder, array $options) {

        $builder->add('routeId', 'hidden');

        foreach (GroupListRepository::$roleNameMap as $key=>$value){
            $builder->add($value, 'checkbox',array('label' => '', 'required' => false,));
        }       
    }

下面是我的FormBuilder类，我想在其中调用上面的实体存储库函数

public static $roleNameMap = array(
            self::ROLE_SUPER_ADMIN => 'superAdmin',
            self::ROLE_MANAGEMEN => 'management',
            self::ROLE_MANAGERS => 'manager',
            self::ROLE_IT_STAFF => 'itStaff',
            self::ROLE_CS_CUSTOMER => 'csCustomer',
            self::ROLE_CS => 'cs',
            self::ROLE_DEALER => 'dealer',
            self::ROLE_ACCOUNT_STAFF => 'accountStaff',
            self::ROLE_BROKER_USER => 'staff',
    );

    public function getGroupListArray()
        {
            $qb = $this->createQueryBuilder('g')
                ->orderBy('g.hierarchy','ASC');
            $query = $qb->getQuery();
            $groupList = $query->execute();
            $roleNameMap = array();
            foreach ($groupList as $role){
                $roleNameMap[$role->getId()] = $role->getRole();
            }

            return $roleNameMap;
        }

public function buildForm(FormBuilderInterface $builder, array $options) {

        $builder->add('routeId', 'hidden');

        foreach (GroupListRepository::$roleNameMap as $key=>$value){
            $builder->add($value, 'checkbox',array('label' => '', 'required' => false,));
        }       
    }

我能够获得上面代码中所示的静态变量，但我不知道如何访问symfony2中form builder类中的存储库函数

提前谢谢

它在表单生成器中不可用，通常也不需要。这也不是Symfony表单的工作方式。对于你想做的事情，你可以试试这样的。它将创建与角色列表对应的复选框列表

$builder->add(
  'roles',
  'entity',
  array(
    'class' => 'Acme\DefaultBundle\Entity\Group',
    'expanded' => true,
    'multiple' => true,
    'property' => 'role', // Or use __toString()
    'query_builder' => function ($repository) {
      return $repository->createQueryBuilder('g')
        ->orderBy('g.hierarchy', 'ASC');
    }            
  )
);

如果您确实需要表单生成器中的存储库，则将表单类型创建为服务，并向实体管理器注入DIC。或者在创建表单类型时直接将其传递到表单类型中。

您不需要创建查询生成器函数，可以使用存储库中的查询，如下所示：

形式如下：

'query_builder' => function(MyCustomEntityRepository $ttr) {
    return $ttr->queryForCustomResultsWithQueryBuilder();
}

在存储库中：

public function queryForCustomResultsWithQueryBuilder($published=true) {
    $queryBuilder =  $this->getEntityManager()->createQueryBuilder();

    return $queryBuilder->select('tt')
            ->from('ifm\CustomBundle\Entity\CustomEntity','tt')
            ->where('tt.published = ?1')
            ->orderBy('tt.code', 'ASC')
            ->setParameters(array(1=>$published))
    ;
}

请注意，queryForCustomResultsWithQueryBuilder返回的是QueryBuilder，而不是结果。如果还需要一个结果，则需要在reposiory中编写一个find函数
