如何以奏鸣曲形式嵌入另一个实体的字段？

Question

我有两个实体Sport和Tarif（按价格换算），由ManyToOne关系链接。

我只想使用一个管理表单（在Sonata Admin Bundle中）来创建或删除具有三个字段的Sport：

• 诽谤（=名称）
• valeurDeBase（=价格值），它是Tarif实体的数字属性
• conditionDeReduction（=有折扣的条件），它是Tarif实体的文本属性

我正在寻找一种实现此目的的方法，发现使用了CollectionType（ https://sonata-project.org/bundles/doctrine-orm-admin/master/doc/reference/form_field_definition.html ）来嵌入Tarif字段在SportAdmin表单中，但无法正常工作，如下所示：

这是实体：

Sport.php

谢谢您的帮助。

Answer 1

最后，我为Tarif创建了一个管理块，并使用sonata_type_admin将其嵌入到SportAdmin中。 它运作完美。 这是SportAdmin.php

<?php

// src/AppBundle/Admin/SportAdmin.php
namespace AppBundle\Admin;

use Sonata\AdminBundle\Admin\AbstractAdmin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\CoreBundle\Form\Type\CollectionType;

class SportAdmin extends AbstractAdmin
{
protected function configureFormFields(FormMapper $formMapper)
{
    $formMapper->add('libelle', 'text');
    $formMapper->add('tarif', 'sonata_type_admin', array(), array(
        'admin_code' => 'admin.tarif'
    ));
}

protected function configureDatagridFilters(DatagridMapper $datagridMapper)
{
    $datagridMapper->add('libelle');
}

protected function configureListFields(ListMapper $listMapper)
{
    $listMapper->addIdentifier('id');
    $listMapper->add('libelle');
    $listMapper->add('tarif.valeurDeBase');
    $listMapper->add('tarif.conditionReduction');
}

public function toString($object)
{
    return $object instanceof Sport
        ? $object->getTitle()
        : 'Sport'; // shown in the breadcrumb on the create view
}
}
