映射的学说错误

Question

我正在Symfony2中创建一个项目,我正在创建实体,我有一个ManyToOne关联,当我尝试从数据库中获取数据时,我收到此错误:

The association Ueb\Creator\Bundle\ModuleBundle\Entity\GenericBlock#fields refers to the owning side field Ueb\Creator\Bundle\ModuleBundle\Entity\GenericField#idGenericBlock which is not defined as association.
The association Ueb\Creator\Bundle\ModuleBundle\Entity\GenericBlock#fields refers to the owning side field Ueb\Creator\Bundle\ModuleBundle\Entity\GenericField#idGenericBlock which does not exist.

我有这门课:

GenericField

 /**
  * GenericField
  *
  * @ORM\Table(name="crt_generic_field")
  * @ORM\Entity(repositoryClass="Ueb\Creator\Bundle\ModuleBundle\Entity\Repository\GenericFieldRepository")
 */
 class GenericField
 {
 /**
 * @var integer
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @var integer
 *
 * @ORM\Column(name="id_generic_block")
 * @ORM\ManyToOne(targetEntity="Ueb\Creator\Bundle\ModuleBundle\Entity\GenericBlock", inversedBy="fields")
 * @ORM\JoinColumn(name="id_generic_block", referencedColumnName="id",nullable=false)
 */
private $idGenericBlock;

/**
 * @var integer
 *
 * @ORM\Column(name="id_field_type")
 * @ORM\ManyToOne(targetEntity="Ueb\Creator\Bundle\ModuleBundle\Entity\FieldTypes")
 * @ORM\JoinColumn(name="id_field_type", referencedColumnName="id",nullable=false)
 */
private $idFieldType;

/**
 * @var integer
 *
 * @ORM\Column(name="isRequired", type="integer")
 */
private $isRequired;

/**
 * @var string
 *
 * @ORM\Column(name="field_name", type="string", length=40)
 */
private $fieldName;

/**
 * @var integer
 *
 * @ORM\Column(name="position", type="integer")
 */
private $position;

/**
 * @var string
 *
 * @ORM\Column(name="field_description", type="string", length=255)
 */
private $fieldDescription;

/**
 * @var array
 *
 * @ORM\Column(name="adicional_info", type="array")
 */
private $adicionalInfo;

我的班级GenericBlock

/**
 * GenericBlock
 *
 * @ORM\Table(name="crt_generic_block")
 * @ORM\Entity(repositoryClass="Ueb\Creator\Bundle\ModuleBundle\Entity\Repository\GenericBlockRepository")
 */
 class GenericBlock
 {

/**
 * @var integer
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @var string
 *
 * @ORM\Column(name="blockName", type="string", length=40)
 * 
 */
private $blockName;

/**
 * @var string
 *
 * @ORM\Column(name="itemBlockName", type="string", length=40)
 */
private $itemBlockName;

/**
 * @var string
 *
 * @ORM\Column(name="blockDescription", type="string", length=255)
 */
private $blockDescription;

/**
 * @var \DateTime
 *
 * @ORM\Column(name="createdAt", type="date")
 */
private $createdAt;

/**
 * @var integer
 *
 * @ORM\Column(name="createdBy")
 * @ORM\ManyToOne(targetEntity="Ueb\Accounts\Bundle\UserBundle\Entity\User")
 * @ORM\JoinColumn(name="createdBy", referencedColumnName="id",nullable=true)
 *
 */
private $createdBy;


/**
 * @var ArrayCollection
 * 
 * @ORM\OneToMany(targetEntity="Ueb\Creator\Bundle\ModuleBundle\Entity\GenericField", mappedBy="idGenericBlock", cascade={"all"})
 */
private  $fields;

我已经看到了一些带有相同错误的问题,并尝试了建议的答案但没有工作,所以我不知道还能做什么,这一定是一个愚蠢的错误.

Answer 1

这是前一段时间,但我的结论是@Column,并@JoinColumn不能一起使用.如果您的提交是关系,您应该@Column在那里省略.例如:

/**
 * @var integer
 *
 * @ORM\Column(name="id_generic_block") <--- ***remove this***
 * @ORM\ManyToOne(targetEntity="Ueb\Creator\Bundle\ModuleBundle\Entity\GenericBlock", inversedBy="fields")
 * @ORM\JoinColumn(name="id_generic_block", referencedColumnName="id",nullable=false)
 */
private $idGenericBlock;

希望这可以帮助...
