如何在symfony2中调用表单类型中的实体存储库的功能

Question

我想在表单类型类中调用函数.function generate array,写在实体存储库类中.使用该数组我将生成动态表单字段.这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;
        }

下面是我的表单构建器类,我想在上面调用实体存储库函数.

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,));
        }       
    }

我能够获得静态变量,如上面的代码所示,但我有一个困惑,我应该如何在symfony2中的表单生成器类中访问存储库函数.

提前致谢.

它在表单构建器中不可用,通常没有必要.它也不是Symfony如何形成的.对于你想要做的事情,你可以尝试这样的事情.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');
    }            
  )
);

请参阅http://symfony.com/doc/master/reference/forms/types/entity.html.

如果您确实需要表单构建器中的存储库,则将表单类型创建为服务,并向实体管理器注入DIC.或者在创建表单时直接将其传递给表单类型.
