Symfony2注册表单，仅包含收集字段的单个记录

Question

因此，我试图在Symfony 2中创建一个包含我的“ Person”实体的注册表单。 人员实体具有一对多联接，我希望注册表单允许用户选择联接的此“许多”面的单个实例。

结构是Users和Institutions 。 用户可以拥有许多机构。 我希望用户在注册时选择一个机构（但是该模型允许稍后再使用）。

基本结构是：

RegistrationType-> PersonType-> PersonInstitutionType

…对应型号：

注册（简单模型）->人员（学说实体）->人员机构（学说实体，来自Person的oneToMany关系）

我试图在RegistrationController预填充一个空的Person ＆ PersonInstitution记录，但它给了我错误：

给定类型为“字符串或Symfony \\ Component \\ Form \\ FormTypeInterface”，“ TB \\ CtoBundle \\ Entity \\ PersonInstitution”的参数

（确定已被修复）。

我已将代码从我的网站移至下面的位置，试图删除所有不相关的位。

这是将Collection字段添加到Person实体和formType的详细解决方案。 您可以通过注册实体解决与注册实体相关的复杂问题。 如果确实需要，我建议您使用与这3个实体相关的连接。 （仅由于条款已接受数据！？）

如果您不会改变意见，请使用以下注释： 注册代码 ：

use TB\CtoBundle\Entity\Person;
/**
  * @ORM\OneToOne(targetEntity="Person")
  * @var Person
  */
protected $person;

人员代码 ：

use TB\CtoBundle\Entity\PersonInstitution;

/**
  * @ORM\OneToMany(targetEntity="PersonInstitution", mappedBy = "person")
  * @var ArrayCollection
  */
private $institutions;

/* I suggest you to define these functions:
setInstitutions(ArrayCollection $institutions),
getInstitutions()
addInstitution(PersonInstitution $institution)
removeInstitution(PersonInstitution $institution)
*/

机构代码 ：

use TB\CtoBundle\Entity\Person;

/**
  * @ORM\ManyToOne(targetEntity="Person", inversedBy="institutions", cascade={"persist"}))
  * @var Person
  */
private $person;

PersonType代码 ：

use TB\CtoBundle\Form\PersonInstitutionType;

->add('institutions', 'collection', array(
                'type' => new PersonInstitutionType(), // here is your mistake!
                // Other options can be selected here.
                //'allow_add' => TRUE,
                //'allow_delete' => TRUE,
                //'prototype' => TRUE,
                //'by_reference' => FALSE,
));

PersonController代码 ：

use TB\CtoBundle\Entity\Person;
use TB\CtoBundle\Entity\PersonInstitution;

/**
  * ...
  */
public funtcion newAction()
{
  $person = new Person;
  $institution = new PersonInstitution;
  $institution->setPerson($person);
  $person->addInstitution($institution);
  $form = $this->createForm(new PersonType($), $person); // you can use formFactory too.

  // If institution field is required, then you have to check,
  // that is there any institution able to chose in the form by the user.
  // Might you can redirect to institution newAction in that case.

  return array( '...' => $others, 'form' => $form);
}
