I am trying to populate the database with the object User and Person by executing<\/p>\n

persist and flush.<\/p>\n

First of all, I am creating the Person object and persist and flush it:<\/p>\n

$person->setFirstname($enquiry->getFirstname());\n$person->setLastname($enquiry->getLastname());\n$person->setLastname($enquiry->getLastname());\n$person->setSex($enquiry->getSex());\n$person->setEmail($enquiry->getEmail());\n$person->setAddress1($enquiry->getAddress1());\n$person->setAddress2($enquiry->getAddress2());\n$person->setCity($enquiry->getCity());\n$person->setZipcode($enquiry->getZipcode());\n$country = $em->getRepository('SciForumVersion2Bundle:Country')->findOneById($enquiry->getCountry());  \n$person->setCountry($country);\n\n$em->persist($person);\n$em->flush();\n<\/code><\/pre>\n
And then my User object:<\/p>\n
$user->setEmail($enquiry->getEmail());\n$user->setPassword($enquiry->getPassword());\n$user->setPersonId($person->getId());\n$user->setDegree($enquiry->getDegree());\n$user->setSex($enquiry->getSex());\n$user->setOrganization($enquiry->getOrganization());\n$user->setTelephone($enquiry->getTelephone());\n$user->setFax($enquiry->getFax());\n$user->setWorkplace($enquiry->getWorkplace());  \n$user->setJobtype($enquiry->getJobtype());\n$user->setResearchField($enquiry->getResearchField());\n$user->setManageConference(0);\n$user->setIp( $IP);\n$user->setStatus( 0 );\n$user->setDateRegistered( time() );\n\n$em->persist($user);\n$em->flush();\n<\/code><\/pre>\n
But when trying to flush() the persist of the user object, I am getting the error:<\/p>\n
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 \n<\/code><\/pre>\n

  1. \n
    I have finally found the problem:<\/p>\n
    When creating the object user, instead of setting those fields<\/p>\n
    $user->setDegree();\n$user->setWorkplace();  \n$user->setJobtype();\n$user->setResearchField();\n<\/code><\/pre>\n
    as objects (because of the OneToMany relation), I gived here only a string, from the form.<\/p>\n
    So, for those fields, the code would be:<\/p>\n
    $degree     = $em->getRepository('SciForumVersion2Bundle:Degree')->findOneById($enquiry->getDegree());\n$workplace  = $em->getRepository('SciForumVersion2Bundle:Workplace')->findOneById($enquiry->getWorkplace());\n$job_type   = $em->getRepository('SciForumVersion2Bundle:JobType')->findOneById($enquiry->getJobtype());\n$research_field = $em->getRepository('SciForumVersion2Bundle:ResearchField')->findOneById($enquiry->getResearchField());\n<\/code><\/pre>\n
    And then:<\/p>\n
    $user->setPerson($person);\n$user->setWorkplace($workplace);    \n$user->setJobtype($job_type);\n$user->setResearchField($research_field);\n<\/code><\/pre>\n
    So: Be careful when you are getting this kind of warnings, you probably have to check if you are populating your object in the right way.<\/p>\n<\/li>\n<\/ol>\n
