违反Doctrine2完整性约束：插入2个一对一关联时为1048

嗨，我得到了例外：

INSERT INTO persons (contact_id, addresses_id, files_id, firstname, middlename, lastname, gender, birthday, cdate, udate, id) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)' with params [2, null, null, "Foo", "", "Bar", 1, null, "2014-01-10 15:59:45", null, null]:
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'addresses_id' cannot be null

当我想创建一个具有新联系人和地址关系的新人时。

控制器：

// Person Contact
$contact = new Contact();
$contact->populate($contactData);
$em->persist($contact);

// Person Address
$address = new Address();
$address->populate($addressData);
$countryRef = $em->getReference('Admin\Entity\Country', $address->getCountriesId());
$address->setCountry($countryRef);
$em->persist($address);

$person = new Person();
$person->populate($personData);
$person->setContact($contact);
$person->setAddress($address);

$em->persist($person);
$em->flush();

地址模型：

class Address implements InputFilterAwareInterface
{
/**
 * Instance of InputFilterInterface.
 *
 * @var InputFilter
 */
private $inputFilter;

/**
 * @var integer
 * @ORM\Id
 * @ORM\Column(name="id", type="integer", nullable=false)
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;

/**
 * @var integer
 * @ORM\Column(name="countries_id", type="integer", nullable=false)
 */
protected $countriesId;

// Removed not important fields

/**
 * @var datetime
 * @ORM\Column(name="cdate", type="datetime", nullable=true)
 */
protected $cdate;

/**
 * @var datetime
 * @ORM\Column(name="udate", type="datetime", nullable=true)
 */
protected $udate;

/**
 * @var \Admin\Entity\Company
 * @ORM\OneToOne(targetEntity="\Admin\Entity\Company", mappedBy="address")
 * @ORM\JoinColumn(name="id", referencedColumnName="addresses_id", nullable=false)
 */
protected $company;

/**
 * @var \Admin\Entity\Person
 * @ORM\OneToOne(targetEntity="\Admin\Entity\Person", mappedBy="address")
 * @ORM\JoinColumn(name="id", referencedColumnName="addresses_id", nullable=false)
 */
protected $person;

/**
 * @var \Admin\Entity\Country
 * @ORM\ManyToOne(targetEntity="\Admin\Entity\Country", inversedBy="addresses")
 * @ORM\JoinColumn(name="countries_id", referencedColumnName="id", nullable=false)
 */
protected $country;

触头型号：

class Contact implements InputFilterAwareInterface
{
/**
 * Instance of InputFilterInterface.
 *
 * @var InputFilter
 */
private $inputFilter;

/**
 * @var integer
 * @ORM\Id
 * @ORM\Column(name="id", type="integer", nullable=false)
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;

/**
 * Primary email address
 *
 * @var string
 * @ORM\Column(name="email", type="string", length=100, nullable=true, options={"comment"="Primary email address"})
 */
protected $email;


// Removed not important fields

/**
 * @var datetime
 * @ORM\Column(name="cdate", type="datetime", nullable=true)
 */
protected $cdate;

/**
 * @var datetime
 * @ORM\Column(name="udate", type="datetime", nullable=true)
 */
protected $udate;

/**
 * @var \Admin\Entity\CompaniesHasPerson
 * @ORM\OneToOne(targetEntity="\Admin\Entity\CompaniesHasPerson", mappedBy="contact")
 * @ORM\JoinColumn(name="id", referencedColumnName="contact_id", nullable=false)
 */
protected $companiesHasPerson;

/**
 * @var \Admin\Entity\Company
 * @ORM\OneToOne(targetEntity="\Admin\Entity\Company", mappedBy="contact")
 * @ORM\JoinColumn(name="id", referencedColumnName="contact_id", nullable=false)
 */
protected $company;

/**
 * @var \Admin\Entity\Person
 * @ORM\OneToOne(targetEntity="\Admin\Entity\Person", mappedBy="contact")
 * @ORM\JoinColumn(name="id", referencedColumnName="contact_id", nullable=false)
 */
protected $person;

而且奇怪的事实是，当我将地址模型与联系人模型切换并首先坚持使用地址模型时，学说将引发错误：

An exception occurred while executing 'INSERT INTO persons (contact_id, addresses_id, files_id, firstname, middlename, lastname, gender, birthday, cdate, udate, id) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)' with params [null, 2, null, "Foo", "", "Bar", 1, null, "2014-01-10 16:16:50", null, null]:
