我有 2 个实体:

1. 问题

/**
 * @ORM\Table()
 * @ORM\Entity
 */
class Question
{
    /**
     * @ORM\Column(type="smallint", nullable=false)
     */
    private $type;

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

    /**
     * @ORM\OneToMany(targetEntity="Option", mappedBy="question")
     */
    private $options;
}

2. 选项

/**
 * @ORM\Table()
 * @ORM\Entity
 */
class Option
{
    /**
     * @ORM\ManyToOne(targetEntity="Question", inversedBy="options")
     * @ORM\JoinColumn(name="question_id", referencedColumnName="id")
     */
    private $question;

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

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

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

根据Question类型,需要使用不同的 formType,其中仅包含一些Option字段。

例如:

Questionwithtype = X应该有带字段的表单$field_for_question_type_x

Questionwithtype = Y应该有带字段的表单$field_for_question_type_y

等等

我还创建了那些不同的 formTypes,所以问题是我如何告诉 Sonata Admin$formMapper添加此类表单的集合(基于 Question 实体类型)?

目前它看起来像这样:

protected function configureFormFields(FormMapper $formMapper)
{
    $Question = $this->getSubject();

    $formMapper->add('test_field');

    if ($Question->getId()) {
        $formMapper->with('Options');

        switch ($Question->getType()) {
            case 'X':
                // Here I would need to add collection of \My\Bundle\Form\OptionXType()
                $formMapper->add('options', ????????);
                break;
            case 'Y':
                // Here I would need to add collection of \My\Bundle\Form\OptionYType()
                $formMapper->add('options', ????????);
                break;
        }
    }
}

应该添加什么来提供这样的功能?

答案很简单:

->add('options', 'sonata_type_collection',
    array(),
    array(
        'edit' => 'inline',
        'inline' => 'table',
        'admin_code' => $type_based_admin_code # each has custom form configuration
    )
)
