映射問題Doctrine＆Symfony

Question

我有3個實體映射導致一些問題。

這兩個問題IM飾面是：

1. 當我使用學說命令行架構更新，它消除在item_type_field表中的列「ITEM_TYPE」。它看起來像教條沒有看到YML文件中的這一列，而它在那裏。

2. 在Symfony應用程序中，TypeField和FieldType之間的映射不起作用。當我轉儲字段的FieldType時，它返回null。

我錯過了什麼嗎？

實體和映射：

class ItemType 
{ 
    protected $id; 
    protected $title; 
    protected $description; 
    protected $fields; 


    public function __construct(){ 
     $this->fields = new ArrayCollection(); 
    } 


    public function getId() 
    { 
     return $this->id; 
    } 

    public function setTitle($title) 
    { 
     $this->title = $title; 

     return $this; 
    } 

    public function getTitle() 
    { 
     return $this->title; 
    } 

    public function setDescription($description) 
    { 
     $this->description = $description; 

     return $this; 
    } 

    public function getDescription() 
    { 
     return $this->description; 
    } 

    public function addField(\Aveqcms\CoreBundle\Entity\TypeField $field) 
    { 
     $field->setItemType($this); 
     $this->fields[] = $field; 

     return $this; 
    } 

    public function removeField(\Aveqcms\CoreBundle\Entity\TypeField $field) 
    { 
     $this->fields->removeElement($field); 
    } 

    public function getFields() 
    { 
     return $this->fields; 
    } 
} 


class TypeField 
{ 

    private $id; 
    private $item_type; 
    private $field_type; 


    public function getId() 
    { 
     return $this->id; 
    } 

    public function setItemType($itemType) 
    { 
     $this->item_type = $itemType; 
     return $this; 
    } 

    public function getItemType() 
    { 
     return $this->item_type; 
    } 

    public function setFieldType($fieldType) 
    { 
     $this->field_type = $fieldType; 

     return $this; 
    } 

    public function getFieldType() 
    { 
     return $this->field_type; 
    } 
} 


class FieldType 
{ 

    private $id; 
    private $title; 
    private $fields; 

    public function __construct() 
    { 
     $this->fields = new ArrayCollection(); 
    } 

    public function getId() 
    { 
     return $this->id; 
    } 

    public function setTitle($title) 
    { 
     $this->title = $title; 
     return $this; 
    } 


    public function getTitle() 
    { 
     return $this->title; 
    } 
} 

映射文件：

Acme\CoreBundle\Entity\ItemType: 
    type: entity 
    table: item_type 
    id: 
     id: 
      type: integer 
      generator: { strategy: AUTO } 
    fields: 
     title: 
      type: string 
      length: 255 
     description: 
      type: string 
      length: 255 
    oneToMany: 
     fields: 
      targetEntity: TypeField 
      mappedBy: item_type 
      cascade: [persist]

      inversedBy: fields

      mappedBy: field_type 

Answer 1

在TYPEFIELD你有多對一重複兩次。第二個壓倒第一個，因爲教義沒有看到它。

Acme\CoreBundle\Entity\TypeField: 
type: entity 
table: item_type_field 
id: 
    id: 
     type: integer 
     generator: { strategy: AUTO } 
manyToOne: 
    field_type: 
     targetEntity: FieldType 
     inversedBy: fields 
     joinColumn: 
      name: field_type 
      referencedColumnName: id   
#manyToOne: *** Get rid of this *** 
    item_type: 
     targetEntity: ItemType 
     inversedBy: fields 
     joinColumn: 
      name: item_type 
      referencedColumnName: id 

這可能會也可能不會解決所有問題。它當然不能解決你非常混亂的命名約定的問題。
