Symfony 3合并表格-集合打印错误（仅打印标签）

Question

我正在使用symfony 3.0.5。 我有“集合”类型的表单。 当我打印收集表格时，我只会得到标签。

我的代码：UserType.php

class UserType extends AbstractType
{
/**
 * @param FormBuilderInterface $builder
 * @param array $options
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('firstname')
        ->add('lastname')
        ->add('username')
        ->add('password')
        ->add('address')
    ;
}

/**
 * @param OptionsResolver $resolver
 */
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'AppBundle\Entity\User'
    ));
}
}

ClientType.php

class ClientType extends AbstractType
{
/**
 * @param FormBuilderInterface $builder
 * @param array $options
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('money')
        ->add('user',CollectionType::class,array(
            'entry_type' => UserType::class
        ))
    ;
}

/**
 * @param OptionsResolver $resolver
 */
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'AppBundle\Entity\Client'
    ));
}

Client.php

class Client
{
/**
 * @ORM\ManyToOne(targetEntity="User", inversedBy="client")
 * @ORM\JoinColumn(name="id", referencedColumnName="id", onDelete="CASCADE")
 */
private $user;
...//set,get:money,id,...
}

User.php

class User
{
/**
 * @ORM\OneToMany(targetEntity="Client", mappedBy="user")
 */
private $client;

public function __construct()
{
    $this->client = new ArrayCollection();
}
....//set get: name,id,lastname...
}

ClientController.php

public function createAction(Request $request)
{
    $client = new Client();
    $user = new User();

    $form = $this->createForm(ClientType::class,$client)
            ->add('submit',ButtonType::class);
....
}

create.html.twig

{% extends 'base.html.twig' %}

{% block body %}
    <h2 class="page-header">Client</h2>
    {{ form_start(form) }}
    {{ form_widget(form) }}
    {{ form_end(form) }}
{% endblock %}

Answer 1

您可以尝试以下方法：

{{ form_start(form) }}
{{ form_row(form.money) }}
{{ form_row(form.user.firstname) }}
{{ form_row(form.user.lastname) }}
{{ form_end(form) }}

[编辑]

使用collectionType时（是否出错？），您需要对用户循环，请尝试：

{{ form_start(form) }}
{{ form_row(form.money) }}
{% for user in form.user %}
    {{ form_row(user.firstname) }}
    {{ form_row(user.lastname) }}
{% endfor %}
{{ form_end(form) }}

但我认为您的实体配置错误，也许可以考虑一下：

use Symfony\Bridge\Doctrine\Form\Type\EntityType;
// ...

$builder->add('user', EntityType::class, array(
    'class' => 'AppBundle:User',
));
