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 $field_for_question_type_z;
}
根据Question
类型,需要使用不同的 formType,其中仅包含一些Option
字段。
例如:
Question
withtype = X
应该有带字段的表单$field_for_question_type_x
Question
withtype = 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?
