Symfony2: spl_object_hash() dự kiến ​​tham số 1 là đối tượng, chuỗi được đưa ra trong học thuyết

Question

Tôi cố gắng để tạo database với đối tượng người dùng và Person bằng cách thực hiện

kiên trì và tuôn ra.

Trước hết, tôi đang tạo ra các đối tượng Person và tồn tại và tuôn nó:

$person->setFirstname($enquiry->getFirstname()); 
$person->setLastname($enquiry->getLastname()); 
$person->setLastname($enquiry->getLastname()); 
$person->setSex($enquiry->getSex()); 
$person->setEmail($enquiry->getEmail()); 
$person->setAddress1($enquiry->getAddress1()); 
$person->setAddress2($enquiry->getAddress2()); 
$person->setCity($enquiry->getCity()); 
$person->setZipcode($enquiry->getZipcode()); 
$country = $em->getRepository('SciForumVersion2Bundle:Country')->findOneById($enquiry->getCountry()); 
$person->setCountry($country); 

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

Và sau đó đối tượng người dùng của tôi:

$user->setEmail($enquiry->getEmail()); 
$user->setPassword($enquiry->getPassword()); 
$user->setPersonId($person->getId()); 
$user->setDegree($enquiry->getDegree()); 
$user->setSex($enquiry->getSex()); 
$user->setOrganization($enquiry->getOrganization()); 
$user->setTelephone($enquiry->getTelephone()); 
$user->setFax($enquiry->getFax()); 
$user->setWorkplace($enquiry->getWorkplace()); 
$user->setJobtype($enquiry->getJobtype()); 
$user->setResearchField($enquiry->getResearchField()); 
$user->setManageConference(0); 
$user->setIp($IP); 
$user->setStatus(0); 
$user->setDateRegistered(time()); 

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

Nhưng khi cố gắng tuôn() các tồn tại của đối tượng người dùng, tôi gặp lỗi:

Warning: spl_object_hash() expects parameter 1 to be object, string given in /home/milos/workspace/conference2.0/vendor/doctrine/lib/Doctrine/ORM/UnitOfWork.php line 1095 

Và đây là entier LOG:

Answer 1

tôi cuối cùng đã tìm thấy các vấn đề:

Khi tạo đối tượng người dùng, thay vì thiết lập những lĩnh vực

$user->setDegree(); 
$user->setWorkplace(); 
$user->setJobtype(); 
$user->setResearchField(); 

như các đối tượng (vì mối quan hệ OneToMany), tôi gived đây chỉ một chuỗi, từ biểu mẫu.

Vì vậy, đối với những lĩnh vực, mã sẽ là:

$degree  = $em->getRepository('SciForumVersion2Bundle:Degree')->findOneById($enquiry->getDegree()); 
$workplace = $em->getRepository('SciForumVersion2Bundle:Workplace')->findOneById($enquiry->getWorkplace()); 
$job_type = $em->getRepository('SciForumVersion2Bundle:JobType')->findOneById($enquiry->getJobtype()); 
$research_field = $em->getRepository('SciForumVersion2Bundle:ResearchField')->findOneById($enquiry->getResearchField()); 

Và sau đó:

$user->setPerson($person); 
$user->setWorkplace($workplace);  
$user->setJobtype($job_type); 
$user->setResearchField($research_field); 

Vì vậy: Hãy cẩn thận khi bạn đang nhận được loại này cảnh báo, bạn có thể có để kiểm tra nếu bạn đang phổ biến đối tượng của mình theo đúng cách.
