CreatedAt/UpdatedAt Timestamps

Probably the most popular of all behaviors, adds created_at and updated_at timestamp columns to your entity, automatically saving datetime when a record is created or updated, respectively.

Usage

php
use Cycle\Annotated\Annotation\Column;
use Cycle\Annotated\Annotation\Entity;
use Cycle\ORM\Entity\Behavior;

#[Entity]
#[Behavior\CreatedAt(
    field: 'createdAt',   // Required. By default 'createdAt'
    column: 'created_at'  // Optional. By default 'null'. If not set, will be used information from property declaration.
)]
#[Behavior\UpdatedAt(
    field: 'updatedAt',   // Required. By default 'updatedAt' 
    column: 'updated_at'  // Optional. By default 'null'. If not set, will be used information from property declaration.
)]
class Page
{
    #[Column(type: 'primary')]
    private int $id;
    
    #[Column(type: 'datetime')]
    private \DateTimeImmutable $createdAt;
    
    #[Column(type: 'datetime', nullable: true)]
    private ?\DateTimeImmutable $updatedAt = null;
}

Behavior\CreatedAt and Behavior\UpdatedAt behaviors are able to declare columns created_at and updated_at of the required type and define them to the entity schema. So it's unnecessary to use #[Column] attribute for these fields.

Note: If you have a custom created_at or updated_at column declaration, it should be compatible with Behavior\CreatedAt and Behavior\UpdatedAt column types, otherwise an exception will be thrown.
