Symfony sonata_type_模型字段的自定义选项列表,带有sonata Admin
我正在使用Sonata Admin,我有一个类别字段,我需要按顺序显示它们,就像选择中的树一样:Symfony sonata_type_模型字段的自定义选项列表,带有sonata Admin,symfony,sonata-admin,Symfony,Sonata Admin,我正在使用Sonata Admin,我有一个类别字段,我需要按顺序显示它们,就像选择中的树一样: <select> <option>Category father-1</option> <option>--Category child-1-1</option> <option>--Category child-1-2</option> <option>--Categor
<select>
<option>Category father-1</option>
<option>--Category child-1-1</option>
<option>--Category child-1-2</option>
<option>--Category child-1-3</option>
<option>----Category child-1-3-1</option>
<option>----Category child-1-3-2</option>
<option>--Category child-1-4</option>
<option>--...</option>
<option>Category father-2</option>
</select>
这显示了错误:
The option "choice_list" with value "Array" is expected to be of type "null", "Symfony\Component\Form\Extension\Core\ChoiceList\ChoiceListInterface"
我不确定是否必须使用字段类型“sonata\u type\u model”或“choice”试试:
->add('category', 'entity', array(
'class' => 'Acme\Entity\Category',
)
仅当您有实体类别时,此选项才有效
请参阅关于为SonataAdminBundle的类别
实体创建树编辑器。是俄文的同一篇文章,但在第一个变体中包含缺失的代码。好的,我已经在树中排序了类别列表,将其包含在相关实体中,如下所示:
protected function configureFormFields(FormMapper $formMapper)
{
$em = $this->modelManager->getEntityManager('MyBundle\Entity\Category');
$query = $em->createQueryBuilder('c')
->select('c')
->from('MyBundle:Category', 'c')
->where('c.parent IS NOT NULL')
->orderBy('c.root, c.lft', 'ASC');
$formMapper
...
->add('categoria', 'sonata_type_model', array(
'required' => true,
'query' => $query
))
...
;
}
我希望它能帮助某人在阅读了上述答案后,我必须执行以下操作才能获得OP所需的功能:
protected function configureFormFields(FormMapper $formMapper)
{
$em = $this->modelManager->getEntityManager('YourBundleFile\YourBundleFileBundle\Entity\YourEntity');
$qb = $em->createQueryBuilder();
$qb = $qb->add('select', 'u')
->add('from', 'YourBundleFile\YourBundleFileBundle\Entity\YourEntity u');
$query = $qb->getQuery();
$arrayType = $query->getArrayResult();
$formMapper
->add('yourProperty', 'choice', array('choices'=>$arrayType))
-end();
}
我不得不使用companybundle:Category
。您好,您是否尝试过使用required false?我得到了并且一直得到不能设置空值,除了Categoria和得到了空值,谢谢找到我的解决方案。如果您希望它是“必需的”=>false。setCategory(Category$Category=null),因此提交表单时不会将值设置为null并抛出错误。
protected function configureFormFields(FormMapper $formMapper)
{
$em = $this->modelManager->getEntityManager('YourBundleFile\YourBundleFileBundle\Entity\YourEntity');
$qb = $em->createQueryBuilder();
$qb = $qb->add('select', 'u')
->add('from', 'YourBundleFile\YourBundleFileBundle\Entity\YourEntity u');
$query = $qb->getQuery();
$arrayType = $query->getArrayResult();
$formMapper
->add('yourProperty', 'choice', array('choices'=>$arrayType))
-end();
}
