如何在提交symfony3表單時在子實體上設置父標識

Question

如何在TaskLine實體上設置task_id？

類似的問題：

1. Doctrine: How to insert foreign key value
2. Best practice for inserting objects with foreign keys in symfony2
3. Doctrine 2 entity association does not set value for foreign key

我得到這個錯誤：

Neither the property "task_id" nor one of the methods "getTaskId()", "taskId()", "isTaskId()", "hasTaskId()", "__get()" exist and have public access in class "AppBundle\Entity\TaskLine" 

注：通常I W與PropelORM的ork。

我在嘗試保存與任務實體相關的新TaskLine實體。我發佈的JSON負載看起來像這樣。

{ 
    "id": null, 
    "task_id": 1, 
    "note" : "new note" 
} 

在我json_decode請求負載並提交給$form->submit($note_data)控制器，$形式的一個實例：

class TaskNoteType extends AbstractType 
{ 
    /** 
    * @param FormBuilderInterface $builder 
    * @param array $options 
    */ 
    public function buildForm(FormBuilderInterface $builder, array $options) 
    { 
     $builder 
     ->add('task_id', NumberType::class) 
     ->add('note', TextType::class) 
     ; 
    } 

    /** 
    * @param OptionsResolver $resolver 
    */ 
    public function configureOptions(OptionsResolver $resolver) 
    { 
     $resolver->setDefaults(array(
      'data_class' => 'AppBundle\Entity\TaskLine' 
     )); 
    } 
} 

這是我的任務實體

class Task 
{ 
    /** 
    * @var string 
    * 
    * @ORM\Column(name="description", type="string", length=150, nullable=true) 
    */ 
    private $description; 

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

TaskLine實體

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

    /** 
    * @var \AppBundle\Entity\Task 
    * 
    * @ORM\ManyToOne(targetEntity="AppBundle\Entity\Task") 
    * @ORM\JoinColumns({ 
    * @ORM\JoinColumn(name="task_id", referencedColumnName="id") 
    * }) 
    */ 
    private $task; 


    /** 
    * Get id 
    * 
    * @return integer 
    */ 
    public function getId() 
    { 
     return $this->id; 
    } 

    /** 
    * Set task 
    * 
    * @param \AppBundle\Entity\Task $task 
    * 
    * @return TaskLine 
    */ 
    public function setTask(\AppBundle\Entity\Task $task = null) 
    { 
     $this->task = $task; 

     return $this; 
    } 

    /** 
    * Get task 
    * 
    * @return \AppBundle\Entity\Task 
    */ 
    public function getTask() 
    { 
     return $this->task; 
    } 
}

，我發現我的答案在這裏： Best Practice for inserting objects with foreign keys in Symfony2

回答：Tuan nguyen

In ORM you have to set Foreign key by an object which your entity associated with. You could use EntityManager#getReference to get a reference to category entity without loading it from DB. Like this

$category = $entityManager->getReference('YourProject\Entity\Category', $categoryId); 
$product = new Product(); 
$product->setCategory($category);

1. Doctrine: How to insert foreign key value

Following function you should have already in your Slider entity (or similar).

public function addImage(Image $image) { 
$image->setSlider($this); // This is the line you're probably looking for 
$this->images[] = $image; 

return $this; } 

What it does is if you persist the entity it writes the ID of the Slider (sid) into your Image.

Doctrine 2 entity association does not set value for foreign key

I found something in the Doctrine 2 documentation:

Changes made only to the inverse side of an association are ignored. Make sure to update both sides of a bidirectional association (or at least the owning side, from Doctrine’s point of view) As in my case the owning side is the User I must update it. Doctrine 1 was able to manage it automatically... too bad.
