Doctrine One-To-Many Relationship Won't Save - Integrity Constraint Violation

Question

I\'m attempting to use Doctrine ORM Associations. I\'ve read several tutorials and the online docs, but it\'s not working, and I\'m honestly not sure what I\'m doing wrong h

Answer 1

The problem is that you are not setting the user entity in your history class. The association stuff does not do this automatically.

class UserHistory
{
    public function setUser($user) { $this->user = $user; }

class User
{
    public function addHistory($history)
    {
        $this->history->add($history);
        $history->addUser($this);  // *** This is what you are missing
    }

// In your controller class
$user->addHistory($history);
