php - 如何使用 Sonata Admin Bundle 在 Symfony 项目中列出具有简单数组类型字段的对象

Question

我有一个代表产品的类，该产品的属性映射为代表尺寸集合的简单数组

<?php

namespace Middleware\MainBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Product
 *
 * @ORM\Table(name="product", uniqueConstraints={...})
 * @ORM\Entity(repositoryClass="...")
 */
class Product {

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

    // more properties
    // ...   


    /**
     * @ORM\Column(type="simple_array", nullable=true)
     */
    private $sizes;



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




    /**
     * Set sizes
     *
     * @param array $sizes
     * @return Product
     */
    public function setSizes($sizes)
    {
        $this->sizes = $sizes;

        return $this;
    }

    /**
     * Get sizes
     *
     * @return array 
     */
    public function getSizes()
    {
        return $this->sizes;
    }

}

我的 ProducAdmin 类如下

    <?php

namespace Middleware\MainBundle\Admin;

use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\AdminBundle\Show\ShowMapper;

class ProductAdmin extends Admin
{
    /**
     * @param DatagridMapper $datagridMapper
     */
    protected function configureDatagridFilters(DatagridMapper $datagridMapper)
    {
        $datagridMapper
            ->add('id')
            ->add('sizes') // I get a error ContextErrorException: Notice: Array to string conversion
        ;
    }

    /**
     * @param ListMapper $listMapper
     */
    protected function configureListFields(ListMapper $listMapper)
    {
        $listMapper
            ->add('id')            
            ->add('sizes') // I get a error ContextErrorException: Notice: Array to string conversion
            ->add('_action', 'actions', array(
                'actions' => array(
                    'show' => array(),
                    'edit' => array(),
                    'delete' => array(),
                )
            ))
        ;
    }

    /**
     * @param FormMapper $formMapper
     */
    protected function configureFormFields(FormMapper $formMapper)
    {
        $sizes = array();
        for ($index = 35; $index <= 48; $index++) {
            $sizes[$index] = $index . ""; 
        }

        $formMapper            
            ->add('sizes', 'choice', array('required' => false, 'expanded' => true, 'multiple' => true, 'choices' => $sizes)) // works fine
        ;
    }

    /**
     * @param ShowMapper $showMapper
     */
    protected function configureShowFields(ShowMapper $showMapper)
    {
        $showMapper
            ->add('id')            
            ->add('sizes') // I get a error ContextErrorException: Notice: Array to string conversion
        ;
    }
}

我如何使用 Sonata Admin Bundle 管理像大小这样的字段？非常感谢

Answer 1

虽然结果并不美好。我已经解决了这个问题，只是在 configureShowFields 和 configureListFields 方法上将“array”类型添加到“sizes”字段。结果显示大小字段如 [0 => 38] [1 => 40] [2 => 42] [3 => 43] [4 => 45] [5 => 46] 我希望它类似于38, 40, 42, 43, 45, 46

我所做的改变:

    /**
     * @param ListMapper $listMapper
     */
    protected function configureListFields(ListMapper $listMapper)
    {
        $listMapper
            ->add('id')                
            ->add('sizes', 'array') // I've just added array type
            ->add('_action', 'actions', array(
                'actions' => array(
                    'show' => array(),
                    'edit' => array(),
                    'delete' => array(),
                )
            ))
        ;
    }
    /**
     * @param ShowMapper $showMapper
     */
    protected function configureShowFields(ShowMapper $showMapper)
    {
        $showMapper
            ->add('id')                
            ->add('sizes', 'array') // I've just added array type
        ;
    }

如果有更好的方法，我将不胜感激。谢谢
