Php 使用Sonata Admin在Symfony2.6中创建实体

这是我在产品详细信息页面上显示的产品规格：-

平方英尺细分

 Total Heated Area:    4,322 sq. ft.
 1st Floor:            2,586 sq. ft.
 2nd Floor:            1,521 sq. ft.
 Apartment:            215 sq. ft.
 Lanai:                715 sq. ft.
 Balcony/Veranda:      323 sq. ft.
 Entry:                236 sq. ft.

床/浴室

 Bedrooms:             4
 Full Bathrooms:       4
 Half Bathrooms:       2

 Width:                59' 8"
 Depth:                104' 0"

 Location:             Rear

 Standard Foundations: Slab

基础类型

 Type:                 Attached
 Area:                 859 sq. ft.
 Details:              3 cars
 Location:             Rear

 Standard Foundations: Slab

为此，我现在创建了3个实体：-

规格类别

规格

产品

规格类别：-

/**
 * SpecificationCategory
 * @ORM\Table(name="specification_category")
 * @ORM\Entity
 */
class SpecificationCategory
{
/**
 * @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=255)
 */
private $name;

规范实体：-

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

/**
 * @var \XXX\Bundle\XXXBundle\Entity\SpecificationCategory
 *
 * @ORM\ManyToOne(targetEntity="XXX\Bundle\XXXBundle\Entity\SpecificationCategory")
 * @ORM\JoinColumns({
 * @ORM\JoinColumn(name="specification_category_id", referencedColumnName="id")
 * })
 */
private $specificationCategory;

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

/**
 * @var string
 *
 * @ORM\Column(name="description", type="text", nullable=true)
 */
private $description;

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

/**
 * @var integer
 *
 * @ORM\Column(name="price", type="integer", length=11, nullable=true)
 */
 private $price;

产品：-

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

/**
 * @ORM\ManyToMany(targetEntity="XXX\Bundle\XXXBundle\Entity\Specification")
 * @ORM\JoinTable(name="product_specification",
 *      joinColumns={@ORM\JoinColumn(name="product_id", referencedColumnName="id")},
 *      inverseJoinColumns={@ORM\JoinColumn(name="specification_id", referencedColumnName="id")}
 *      )
 **/
private $specification;

现在，在管理中，客户端需要首先创建规范类别，如：-“平方英尺分解”，然后创建规范名称，如：-“总加热面积”和他的值

这是完美的工作

问题是客户希望在Admin中输入这些字段的静态值…这样他就可以在上传产品时输入值，而不是每次添加单独的规格、相同的名称和不同的值

我们将非常感谢您的帮助。 谢谢
