而在學說2訪問代理類的屬性是什麼EntityNotFoundException可能的原因是什麼?不管怎樣,下面是我的實體的結構:EntityNotFoundException教義2代理類
/**
* @ORM\Table(name="comments")
*
* @ORM\InheritanceType("JOINED")
* @ORM\DiscriminatorColumn(name="comment_type", type="smallint")
* @ORM\DiscriminatorMap({
* 1 = "VisitorComment",
* 2 = "MemberComment"
* })
*/
class Comment
{
//with common properties of its subclasses
}
子類如下:
/**
* @ORM\Table(name="member_comments")
*/
class MemberComment extends Comment
{
/**
* owning side
*
* @var Member $author
*
* @ORM\ManyToOne(targetEntity="Member")
* @ORM\JoinColumn(name="author_id", referencedColumnName="id", nullable=false)
*/
private $author;
/**
* Set author
*
* @param Member $author
*/
public function setAuthor($author)
{
$this->author = $author;
}
/**
* Get author
*
* @return Member
*/
public function getAuthor()
{
return $this->author;
}
}
/**
* @ORM\Table(name="visitor_comments")
*/
class VisitorComment extends Comment
{
/**
* owning side
*
* @var Visitor $author
*
* @ORM\ManyToOne(targetEntity="Visitor")
* @ORM\JoinColumn(name="author_id", referencedColumnName="id", nullable=false)
*/
private $author;
/**
* Set author
*
* @param string $author
*/
public function setAuthor($author)
{
$this->author = $author;
}
/**
* Get author
*
* @return Visitor
*/
public function getAuthor()
{
return $this->author;
}
}
當我調用$ comment-> getAuthor()發生異常 - >的getFirstName()< 假設作爲會員或訪客實體的作者具有名字屬性>。在這種情況下,getAuthor()返回VisitorProxy或MemberProxy的代理類。
請幫助我。我對教義仍然陌生。
這是我的錯。因爲我還是手動添加數據庫中我的數據,我錯誤地交換訪問者成員的評論和成員向顧客作爲作者的評論。 – Floricel
