可捕获的致命错误：传递给...的参数1必须是...的实例，给定数组

我想注册一个用户。在我的数据库中，我有一个user带有FK的表，player_id在我的玩家表中，我有一个team_id来自团队表的FK 。

这是我的RegisterType表格：

class RegisterType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('userFirstname', 'text', [
                'label' => 'Given name*',
                'attr'  => [
                    'placeholder' => 'Enter your given name.',
                ],
            ])
            ->add('userSurname', 'text', [
                'label' => 'Family name*',
                'attr'  => ['placeholder' => 'Enter your family name.'],
            ])
            ->add('userType', 'choice', array(
                'choices' => array('E' => 'ENTHOUSIAST', 'P' => 'PLAYER', 'T' => 'TRAINER'),
                'label'   => 'User Type*',
                'attr' => array('placeholder' => 'User Type')
            ))
            ->add('player', new PlayerType())
            ->add('userUsername', 'text', [
                'label' => 'Username*',
                'attr'  => ['placeholder' => 'Enter a username.'],
            ])
            ->add('userEmail', 'email', [
                'label' => 'Email address*',
                'attr'  => ['placeholder' => 'Enter your email address.'],
            ])
            ->add('userPassword', 'repeated', [
                'type'           => 'password',
                'first_name'     => 'password',
                'first_options'  => [
                    'label' => 'Password*',
                    'attr'  => ['placeholder' => 'Enter a password.'],
                ],
                'second_name'    => 'confirm',
                'second_options' => [
                    'label' => 'Password (repeat)*',
                    'attr'  => ['placeholder' => 'Repeat the password.'],
                ],
                'invalid_message' => 'The passwords are not identical.',
            ])
            ->add('btn_register', 'submit', [
                'label' => 'Register',
            ])
        ;
    }

    /**
     * @return string
     */
    public function getName()
    {
        return 'register';
    }
}

如您所见，我已经添加了指向另一个表格“ PlayerType”的链接。这是我的PlayerType表格：

class PlayerType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('playerLicensenumber', 'text', [
                'label' => 'Your License number*',
                'attr'  => ['placeholder' => 'Enter your license number.'],
            ])
            ->add('playerPosition', 'choice', array(
                'choices' => array('T' => 'Trainer', 'S' => 'Spelverdeler', 'R' => 'Receptie/Hoek', 'L' => 'Libero', 'M' => 'Midden', 'O' => 'Opposite', 'A' => 'All-round'),
                'label'         => 'Position you play at*',
                'attr' => array('placeholder' => 'Enter your play position.')
            ))
            ->add('playerBirthyear', 'text', array(
                'label' => 'Your Birth Year',
                'attr'  => ['placeholder' => 'Enter your birth year.'],
                'required' => false
            ))
            ->add('team', 'text', array(
                'label' => 'You play with*',
                'attr'  => ['placeholder' => 'Enter your team.']
            ))
        ;
    }

    /**
     * @return string
     */
    public function getName()
    {
        return 'player';
    }
}

在我的register.html.twig视图中，我的所有用户字段和播放器字段如下所示：

<div class="form-group{{ registerForm.player.playerLicensenumber.vars.valid ? '' : class_error }}">
    {{ form_label(registerForm.player.playerLicensenumber, label|default(),

我的问题是，当我想提交时，出现以下错误：

ContextErrorException: Catchable Fatal Error: Argument 1 passed to VolleyScout\VolleyScoutBundle\Entity\Users::setPlayer() must be an instance of VolleyScout\VolleyScoutBundle\Entity\Players, array given, called in /Applications/mampstack-5.4.20-0/apache2/htdocs/volleyscout/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php on line 360 and defined in /Applications/mampstack-5.4.20-0/apache2/htdocs/volleyscout/src/VolleyScout/VolleyScoutBundle/Entity/Users.php line 609

更新：

609规则是这样的：

public function setPlayer(\VolleyScout\VolleyScoutBundle\Entity\Players $player){
    $this->player = $player;
}

PropertyAccessor.php中的359、360规则

if ($reflClass->hasMethod($setter) && $reflClass->getMethod($setter)->isPublic()) {
        $object->$setter($value);
