Symfony - >如何使用Doctrine创建和修改创建和修改的字段？

I'm new to Symfony2 (or Symfony3) and I can't find how to set doctrine (with annotations config) to automatically save it in my entities when 'created' or 'modified' fields.

我是Symfony2（或Symfony3）的新手，我无法找到如何设置doctrine（带注释配置），以便在“创建”或“修改”字段时自动将其保存在我的实体中。

Here my solution after this time ...

在这之后我的解决方案......

You just need to put this directly into your entity class :

你只需要将它直接放入你的实体类：

/**
 * @ORM\Entity
 * @ORM\HasLifecycleCallbacks
 */
class MyEntity {

   //....

    public function __construct() {
        // we set up "created"+"modified"
        $this->setCreated(new \DateTime());
        if ($this->getModified() == null) {
            $this->setModified(new \DateTime());
        }
    }

    /**
     * @ORM\PrePersist()
     * @ORM\PreUpdate()
     */
    public function updateModifiedDatetime() {
        // update the modified time
        $this->setModified(new \DateTime());
    }

    //....    
}

It works well actually

它实际上运作良好

You can use StofDoctrineExtensionsBundle. This describes in symfony cookbook. It contains Timestampable behavior.

您可以使用StofDoctrineExtensionsBundle。这在symfony cookbook中有所描述。它包含Timestampable行为。

/**
 * @var datetime $created
 *
 * @Gedmo\Timestampable(on="create")
 * @ORM\Column(type="datetime")
 */
private $created;

/**
 * @var datetime $updated
 *
 * @Gedmo\Timestampable(on="update")
 * @ORM\Column(type="datetime")
 */
private $updated;

#3

/**
 *
 * @ORM\PrePersist
 * @ORM\PreUpdate
 */
public function updatedTimestamps()
{
    $this->setModifiedAt(new \DateTime(date('Y-m-d H:i:s')));

    if($this->getCreatedAt() == null)
    {
        $this->setCreatedAt(new \DateTime(date('Y-m-d H:i:s')));
    }
}

You dont need to call in __constructor anything. Just create getter and setter properties created, modified and that is all.

你不需要在__constructor中调用任何东西。只需创建创建，修改的getter和setter属性即可。

If you set first setCreated() on every update you will update also created colum. So put first setModifedAt()

如果您在每次更新时设置第一个setCreated（），您将更新也创建colum。所以把第一个setModifedAt（）

Two more examples (if you're using Yaml or Xml mapping):

还有两个例子（如果您使用的是Yaml或Xml映射）：

Entity\Product:
  type: entity
  table: products
  id:
    id:
      type: integer
      generator:
        strategy: AUTO
  fields:
    name:
      type: string
      length: 32
    created_at:
      type: date
      gedmo:
        timestampable:
          on: create
    updated_at:
      type: datetime
      gedmo:
        timestampable:
          on: update

And xml:

和xml：

<?xml version="1.0" encoding="UTF-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
                  xmlns:gedmo="http://gediminasm.org/schemas/orm/doctrine-extensions-mapping">

    <entity name="Mapping\Fixture\Xml\Timestampable" table="timestampables">
        <id name="id" type="integer" column="id">
            <generator strategy="AUTO"/>
        </id>

        <field name="created_at" type="datetime">
            <gedmo:timestampable on="create"/>
        </field>
        <field name="updated_at" type="datetime">
            <gedmo:timestampable on="update"/>
        </field>
    </entity>

</doctrine-mapping>

The other answers suggest using if statements (which means repeating your property names) and having property-setting logic in the constructor that might never be used.

其他答案建议使用if语句（这意味着重复您的属性名称）并在构造函数中具有可能永远不会使用的属性设置逻辑。

Alternatively, you could have onAdd and onUpdate methods that are called when needed:

或者，您可以使用在需要时调用的onAdd和onUpdate方法：

/**
 * @ORM\PrePersist
 */
public function onAdd()
{
    $this->setAdded(new DateTime('now'));
}

/**
 * @ORM\PrePersist
 * @ORM\PreUpdate
 */
public function onUpdate()
{
    $this->setUpdated(new DateTime('now'));
}
