我正在为我的实体帐户使用 DoctrineExtensions Tree。
我得到以下结果:
$repo = $em->getRepository('NRtworksChartOfAccountsBundle:Accounttree');
$arrayTree = $repo->childrenHierarchy();
实体 Accounttree 是遵循文档的经典实体:
/**
* @Gedmo\Tree(type="nested")
* @ORM\Table(name="Accounttree")
* use repository for handy tree functions
* @ORM\Entity(repositoryClass="Gedmo\Tree\Entity\Repository\NestedTreeRepository")
*/
class Accounttree
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\Column(type="string", length=100, unique = true)
*/
protected $name;
/**
* @ORM\Column(type="string", length=50)
*/
protected $code;
/**
* @Gedmo\TreeLeft
* @ORM\Column(name="lft", type="integer")
*/
protected $lft;
/**
* @Gedmo\TreeLevel
* @ORM\Column(name="lvl", type="integer")
*/
protected $lvl;
/**
* @Gedmo\TreeRight
* @ORM\Column(name="rgt", type="integer")
*/
protected $rgt;
/**
* @Gedmo\TreeRoot
* @ORM\Column(name="root", type="integer", nullable=true)
*/
protected $root;
/**
* @Gedmo\TreeParent
* @ORM\ManyToOne(targetEntity="Accounttree", inversedBy="children")
* @ORM\JoinColumn(name="parent_id", referencedColumnName="id", onDelete="CASCADE")
*/
protected $parent;
/**
* @ORM\OneToMany(targetEntity="Accounttree", mappedBy="parent")
* @ORM\OrderBy({"lft" = "ASC"})
*/
protected $children;
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set name
*
* @param string $name
* @return Account
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}
/**
* Set code
*
* @param string $code
* @return Account
*/
public function setCode($code)
{
$this->code = $code;
return $this;
}
/**
* Get code
*
* @return string
*/
public function getCode()
{
return $this->code;
}
public function setParent(Accounttree $parent=null)
{
$this->parent = $parent;
}
public function getParent()
{
return $this->parent;
}
}
在我的树枝上
{{ account.getParent().getId() }}
给我:

和 {{Account.parent.id}}
给
Key "parent" for array with keys "id, name, code, lft, lvl, rgt, root, __children" does not exist in NRtworksChartOfAccountsBundle:ChartOfAccounts:COA2.html.twig at line 10
我找不到我做错了什么。
帮助 ?
