Question

我已经检查过并且它有值但是当flush（）时，它的等级为null。我在database.Message中创建了fk：执行＆＃39; INSERT INTO用户（用户名，密码，real_name，级别）VALUES（？，？，？，？）＆＃39;与params {＆＃34; 1＆＃34;：＆＃34; abcdef＆＃34;，＆＃34; 2＆＃34;：＆＃34; 21232f297a57a5a743894a0e4a801fc3＆＃34;，＆＃34; 3＆＃34;：＆＃ 34; abcdef＆＃34;，＆＃34; 4＆＃34;：null}：SQLSTATE [23000]：完整性约束违规：1048列＆＃39;级别＆＃39;不能为空我在控制器中的代码

public function testinsertAction()
{
    $user = new \Entities\Usernew();
    $user->setUsername('abcdef');
    $user->setPassword(MD5('admin'));
    $user->setReal_name('abcdef');
    $user->setLevel(1);
    $this->_em->persist($user);
    \Zend_Debug::dump($user);die();
    $this->_em->flush();
}

Answer 1

外键level不能为空，请检查表格结构中的phpMyAdmin字段以允许空值，或者在您的情况下检查 fk 所以你必须插入一些值，外键不能以任何方式为空

doctrine值持续存在但是在flush时为null
