与相关实体保持数据

Question

我有一个预算表单，列出shadow {} 字段中客户实体的数据。总结，预算和客户相互关联。预算有select列，可以通过从所选客户端获取client_id值来存储它。

id

我的客户实体：

<form action="{{ path('panel_add_budget') }}" method="POST">
    <strong>Cliente</strong>
    <div class="form-group">
        <select name="cdg_budget_type[client_id]" class="form-control">
            {% for client in clients %}
                <option value="{{ client.id }}">{{ client.name }}</option>
            {% endfor %}
        </select>
    </div>

    <div class="form-group">
        {{ form_row(form.address) }}
    </div>
    <div class="form-group">
        {{ form_row(form.installments) }}
    </div>
    <div class="form-group">
        {{ form_row(form.check_days) }}
    </div>
    <div class="form-group">
        {{ form_row(form.date_start) }}
    </div>
    <div class="form-group">
        {{ form_row(form.total_value) }}
    </div>

    <button type="submit" class="btn btn-success">Adicionar</button>
</form>

预算实体：

我与预算与客户的关系很多：

CDG\PanelBundle\Entity\Client:
    type: entity
    table: client
    repositoryClass: CDG\PanelBundle\Entity\ClientRepository
    id:
        id:
            type: integer
            id: true
            generator:
                strategy: AUTO
    fields:
        name:
            type: string
            length: 255
        phone:
            type: string
            length: 255
        email:
            type: string
            length: 255
        streetName:
            type: string
            length: 255
            column: street_name
        district:

            length: 255
        number:
            type: string
            length: 255
        city:
            type: string
            length: 255
        zipCode:
            type: string
            length: 255
            column: zip_code
    oneToMany:
        budget:
            targetEntity: Budget
            mappedBy: clientId
    lifecycleCallbacks: {  }

从CDG\PanelBundle\Entity\Budget: type: entity table: budget repositoryClass: CDG\PanelBundle\Entity\BudgetRepository id: id: type: integer id: true generator: strategy: AUTO fields: address: type: string length: 255 installments: type: integer checkDays: type: integer column: check_days dateStart: type: datetime column: date_start dateCreated: type: datetime column: date_created totalValue: type: decimal column: total_value nullable: true manyToOne: clientId: targetEntity: Client inversedBy: budget joinColumn: name: client_id referencedColumnName: id lifecycleCallbacks: { }

完成我的addAction

BudgetController

提交表单时，会抛出异常：

  

警告：spl_object_hash（）期望参数1为对象，给定整数

public function addAction(Request $request)
{
    $form = $this->createForm(new BudgetType());

    if ($request->getMethod() == 'POST') {
        $form->handleRequest($request);

        if ($form->isValid()) {
            $manager = $this->getDoctrine()->getManager();
            $manager->persist($form->getData());
            $manager->flush();

            $this->addFlash('success', 'Novo orçamento adicionado');

            return $this->redirect($this->generateUrl('panel_budgets'));
        }
    }

    return $this->render('PanelBundle:Budget:add.html.twig', array(
        'clients' => $manager->getRepository('PanelBundle:Client')->findAll(),
        'form' => $form->createView()
    ));
}

它的堆栈跟踪：

public function getEntityState($entity, $assume = null)
{
    $oid = spl_object_hash($entity);
    if (isset($this->entityStates[$oid])) {
        return $this->entityStates[$oid];

这对我没有任何意义。我不知道该怎么办。其他的解决方案根本没有帮助我。如果您需要更多代码请问我，我会编辑它。谢谢。

Answer 1

我建议您在实体中使用注释，并开始使用formbuilder。还要将__toString（）方法添加到客户端实体！

您的实体

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Doctrine\Common\Collections\ArrayCollection;

/**
 * Client
 *
 * @ORM\Table()
 * @ORM\Entity
 */
class Client
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var string
     *
     * @ORM\Column(name="name", type="string", length=64)
     */
    private $name;

    // YOUR OTHER CLIENT FIELDS

    /**
     * @ORM\OneToMany(targetEntity="Budget", mappedBy="client")
     **/
    private $budgets;

    public function __construct() {
        $this->budgets = new ArrayCollection();
    }

    /* this function is required to present the entity as a string */
    public function __toString() {
         return $this->name;
    }

}

和第二：

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;

/**
 * Budget
 *
 * @ORM\Table()
 * @ORM\Entity
 */
class Budget
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    // YOUR BUDGET FIELDS

    /**
     * @ORM\ManyToOne(targetEntity="Client", inversedBy="budgets")
     * @ORM\JoinColumn(name="client_id", referencedColumnName="id")
     **/
    private $client;

}

然后在项目主目录的控制台中输入以下命令： （也许你必须在每个命令之前输入 php 这个词）

app/console doctrine:generate:entities AppBundle
app/console doctrine:schema:update --force
app/console doctrine:generate:crud AppBundle:Client
( type YES by the question Do you want to generate the "write" actions [no]?)
app/console doctrine:generate:crud AppBundle:Budget
( type YES by the question Do you want to generate the "write" actions [no]?)

并查看新路线：

app/console router:debug

如您所见，您可以浏览

web / app_dev.php / client / 以及

web / app_dev.php / budget / ，看看吧！

然后在编辑器中打开../src/AppBundle/Form/BudgetType.php，您会发现以下规则：

    $builder
        ->add('client')
    ;

这是将客户端属性添加到表单的位置。 Symfony自动将此表单字段设置为entity formtype。您也可以这样写：

$builder
    ->add('client', 'entity', array(
        'class' => 'AppBundle:Client',
        'empty_value' => '',
    ))
;

现在您可以在预算表单中选择您的客户。

您可能已经注意到这些命令还为您添加了ClientController和BudgetController。 有关formtypes的详细信息，请参阅文档。
