php - Symfony3 / Doctrine - function: adding row with foreign key -


i starting adventure symfony3 (and php) , encountered problem.

at moment application supposed allow user crud projects. displaying works fine, have problem creating.

i have got 2 tables: users , projects. project table contains project data including project owner id of user. symfony docs managed map both tables:

part of "project" entity:

/**  * @orm\manytoone(targetentity="user", inversedby="projects")  * @orm\joincolumn(name="uid", referencedcolumnname="id")  */ private $uid;   /**  * set uid  *  * @param \appbundle\entity\user $uid  *  * @return project  */ public function setuid(\appbundle\entity\user $uid = null) {     $this->uid = $uid;      return $this; }  /**  * uid  *  * @return \appbundle\entity\user  */ public function getuid() {     return $this->uid; }

part of 'user' entity:

private $projects;  public function __construct() {     $this->projects = new arraycollection(); }

at point i'm able display full project info, i.e. project title + project owner details. problem starts implementation of basic function creating new project.

i following doc: http://symfony.com/doc/current/book/doctrine.html#saving-related-entities. thing - don't want create new user well, assign existing user new project. i've created new function in project controller:

/**  * @route("/projects/create/", name="project_create")  */ public function createproject() {     $project = new project();     $project->settitle('webproject');     $project->setdescription('asdfghjkgfdsadfghgfdsdfg');     $project->setlogo('asdf');     $project->setcreatedat(time());     $project->setdateline('-');      // relate product category     $project->setuid(1);      $em = $this->getdoctrine()->getmanager();     $em->persist($project);     $em->flush();      return new response(         'saved new product id: '.$project->getid()     ); }

this function supposed add new project , set user id 1 owner of project. expect doesn't work. error:

catchable fatal error: argument 1 passed appbundle\entity\project::setuid() must instance of appbundle\entity\user, integer given, called in...

well, indeed, that's true. i've no idea how pass there instance of user it's id.

thanks!
