Question

我有3个实体订单实体，产品实体和orderProducts实体，其中包含所有订购的产品。所以基本上orderProducts的映射是一个订单可以有很多产品。我想将orderProducts表单嵌入到订单中。我面临的问题是没有显示嵌入的表单。

订单实体：

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

/**
 * @var \DateTime
 *
 * @ORM\Column(name="order_date", type="datetime")
 */
private $orderDate;

/**
 * @var integer
 *
 * @ORM\ManyToOne(targetEntity="Recipient", inversedBy="orders", cascade={"persist"})
 * @ORM\JoinColumn(name="recipient_id", referencedColumnName="id")
 * @Assert\NotNull()
 */
private $recipientId;


...

/**
 *
 * @ORM\OneToMany(targetEntity="OrderProducts", mappedBy="orders")
 */
private $orderProducts;

/**
 * Constructor
 */
public function __construct()
{
    $this->orderProducts = new ArrayCollection();
}


/**
 * Get id
 *
 * @return integer 
 */
public function getId()
{
    return $this->id;
}

/**
 * Set orderDate
 *
 * @param \DateTime $orderDate
 * @return Orders
 */
public function setOrderDate($orderDate)
{
    $this->orderDate = $orderDate;

    return $this;
}

/**
 * Get orderDate
 *
 * @return \DateTime 
 */
public function getOrderDate()
{
    return $this->orderDate;
}

/**
 * Set recipientId
 *
 * @param guid $recipientId
 * @return Orders
 */
public function setRecipientId($recipientId)
{
    $this->recipientId = $recipientId;

    return $this;
}

/**
 * Get recipientId
 *
 * @return guid 
 */
public function getRecipientId()
{
    return $this->recipientId;
}

....
/**
 * Set orderProducts
 *
 * @param \Inventory\SystemBundle\Entity\OrderProducts $orderProducts
 * @return Orders
 */
public function setOrderProducts(\Inventory\SystemBundle\Entity\OrderProducts $orderProducts = null)
{
    $this->orderProducts = $orderProducts;

    return $this;
}

/**
 * Get orderProducts
 *
 * @return \Inventory\SystemBundle\Entity\OrderProducts 
 */
public function getOrderProducts()
{
    return $this->orderProducts;
}

/**
 * Add orderProducts
 *
 * @param \Inventory\SystemBundle\Entity\OrderProducts $orderProducts
 * @return Orders
 */
public function addOrderProduct(\Inventory\SystemBundle\Entity\OrderProducts $orderProducts)
{
    $this->orderProducts[] = $orderProducts;

    return $this;
}

/**
 * Remove orderProducts
 *
 * @param \Inventory\SystemBundle\Entity\OrderProducts $orderProducts
 */
public function removeOrderProduct(\Inventory\SystemBundle\Entity\OrderProducts $orderProducts)
{
    $this->orderProducts->removeElement($orderProducts);
}

}

产品实体

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

...

/**
 *
 * @ORM\OneToMany(targetEntity="OrderProducts", mappedBy="product")
 */
private $orderProducts;

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


/**
 * Get id
 *
 * @return integer 
 */
public function getId()
{
    return $this->id;
}
...

/**
 * Add orderProducts
 *
 * @param \Inventory\SystemBundle\Entity\OrderProducts $orderProducts
 * @return Product
 */
public function addOrderProduct(\Inventory\SystemBundle\Entity\OrderProducts $orderProducts)
{
    $this->orderProducts[] = $orderProducts;

    return $this;
}

/**
 * Remove orderProducts
 *
 * @param \Inventory\SystemBundle\Entity\OrderProducts $orderProducts
 */
public function removeOrderProduct(\Inventory\SystemBundle\Entity\OrderProducts $orderProducts)
{
    $this->orderProducts->removeElement($orderProducts);
}

/**
 * Get orderProducts
 *
 * @return \Doctrine\Common\Collections\Collection 
 */
public function getOrderProducts()
{
    return $this->orderProducts;
}
}

orderProducts Entity

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

/**
 * @ORM\ManyToOne(targetEntity="Orders", inversedBy="order_products")
 * @ORM\JoinColumn(name="order_id", referencedColumnName="id")
 */
private $orders;

/**
 * @ORM\ManyToOne(targetEntity="Product", inversedBy="order_products")
 * @ORM\JoinColumn(name="product_id", referencedColumnName="id")
 */
private $product;

/**
 * @var string
 *
 * @ORM\Column(name="quantity", type="string", length=255)
 */
private $quantity;


/**
 * Get id
 *
 * @return integer 
 */
public function getId()
{
    return $this->id;
}

/**
 * Set order
 *
 * @return $this
 */
public function setOrders(Orders $orders)
{
    $this->orders = $orders;

    return $this;
}

/**
 * Get order
 *
 * @return mixed
 */
public function getOrders()
{
    return $this->orders;
}

/**
 * Set product
 *
 * @return $this
 */
public function setProduct(Product $product)
{
    $this->product = $product;

    return $this;
}

/**
 * Get product
 *
 * @return mixed 
 */
public function getProduct()
{
    return $this->product;
}
/**
 * Set quantity
 *
 * @param string $quantity
 * @return OrderProducts
 */
public function setQuantity($quantity)
{
    $this->quantity = $quantity;

    return $this;
}

/**
 * Get quantity
 *
 * @return string 
 */
public function getQuantity()
{
    return $this->quantity;
}

}

OrdersType.php

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('orderDate', 'date', array('attr' => array('class' => 'form-control', 'style' => 'margin:10px;width:200px;height:25px;display:inline-block;')))
        ->add('recipientId', new RecipientType())
        ->add('orderProducts', 'collection', array(
                'type' => new OrderProductsType(),
                'options' => array('label' => false),
                'cascade_validation' => true,
                'allow_add' => true        
        ))
        //->add('orderProducts', CollectionType::class, array('entry_type' => OrderProductsType::class))

    ;

}

/**
 * @param OptionsResolverInterface $resolver
 */
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'Inventory\SystemBundle\Entity\Orders'
    ));
}

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

OrderProductsType.php

 public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder

        ->add('product', 'entity', array('label' => 'Product ','attr' => array('class' => 'form-control', 'style' => 'margin:10px;width:200px;height:25px;display:inline-block;'),
                'class' => 'InventorySystemBundle:Product',
                'choice_label' => 'product_name',
            ) )
        ->add('quantity', 'text', array('attr' => array('class' => 'form-control', 'style' => 'margin:10px;width:200px;height:25px;display:inline-block;')))

    ;
}

/**
 * @param OptionsResolverInterface $resolver
 */
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'Inventory\SystemBundle\Entity\OrderProducts'
    ));
}

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

来自OrdersController.php的

createAction

 public function createAction(Request $request)
{
    $order = new Orders();
    $orderProducts = new OrderProducts();
    $order->addOrderProduct($orderProducts);
    $request_all = $request->request->all();
    $form = $this->createCreateForm($order);
    try {
        $form->handleRequest($request);
    } catch (\Exception $e) {
        echo "failed : ".$e->getMessage();
    }

    $recipientId = $request_all['inventory_systembundle_orders']['recipientId'];
    $productId = $request_all['inventory_systembundle_orders']['product'];
    $quantity = $request_all['inventory_systembundle_orders']['quantity'];

    if ($form->isValid()) {

        $em = $this->getDoctrine()->getManager();
        $em->persist($order);
        $em->flush();

        $product = $em->getRepository('InventorySystemBundle:Product')->find($productId);

        $em = $this->getDoctrine()->getManager();

        $orderProducts->setProduct($product);
        $orderProducts->setOrders($order);
        $orderProducts->setQuantity($quantity);
        $em->persist($orderProducts);
        $em->flush();

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

    return array(
        'order' => $order,
        'form'   => $form->createView(),
    );
}

我不确定我错过了什么。我不确定这些协会是否出错了。有人可以帮帮我吗？

twig file

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

{% block body -%}
<div align="right">
    <a href="{{ path('orders') }}">
        Back to the list
    </a>
</div>
  <h1>Orders creation</h1>
  <div class="navbar-form navbar-left">
    {{ form_start(form) }}
    {{ form(form) }} 
    {{ form_end(form) }}  
  </div>
{% endblock %}

我认为您需要添加一些JavaScript代码来呈现集合（您的 orderProducts 表单）

查看symfony文档，这很简单。 Symfony Doc - Embed a collection of forms

Symfony2 - 嵌入式表单未显示
