Doctrain ZF2: Kann Daten für oneToMany nicht speichern Relation

Question

Ich kann nicht Daten in Tabellen speichern, die oneTomany Beziehung in Doctrain2 und ZF2 verwenden.

es gibt den MySQL-Fremdschlüssel Null-Fehler.

An exception occurred while executing 'INSERT INTO phv_image (path, name, suggestion_id) VALUES (?, ?, ?)' with params ["test.png", "test", null]: 

SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'suggestion_id' cannot be null

     $imgObj->setName('test'); 

     $imgObj2 = new \Application\Entity\PhvImage(); 
     $imgObj2->setPath('new.png'); 
     $imgObj2->setName('new'); 

     $arr = array(
       $imgObj,$imgObj2 
     ); 

    $sugg = new \Application\Entity\PhvSuggestion(); 
$sugg->setUser(1); 
$sugg->setImages($arr); 
$sugg->setDescription('test'); 
      $sugg->setSubject('sub'); 
      $em->persist($sugg); 
      $em->flush(); 

    } 

Können Sie mir bitte helfen, dies zu lösen.

Answer 1

Erste in der Klasse PhvSuggestion Sie benötigen einen Konstruktor wie folgt hinzuzufügen:

public function __construct() 
{ 
    $this->images = new \Doctrine\Common\Collections\ArrayCollection(); 
} 

Dann setImages ändern:

public function addImages(\Doctrine\Common\Collections\Collection $images) 
{ 
    foreach ($images as $image) { 
     $image->setSuggestion($this); 
     $this->images->add($image); 
    } 
} 

Sie alle diese Details in der 2-Dokumentation Lehre finden .
