Laravel で Model オブジェクトを新規データとしてコピーする

Posted at

replicate()っていうのを使う。

こんな感じ。

$user = User::find(1)
$new_user = $user->replicate();
$new_user->name = 'new name';
$new_user->save();

内部的には、こんな感じで実装されている。

	/**
	 * Clone the model into a new, non-existing instance.
	 *
	 * @param  array  $except
	 * @return \Illuminate\Database\Eloquent\Model
	 */
	public function replicate(array $except = null)
	{
		$except = $except ?: [
			$this->getKeyName(),
			$this->getCreatedAtColumn(),
			$this->getUpdatedAtColumn(),
		];

		$attributes = array_except($this->attributes, $except);

		with($instance = new static)->setRawAttributes($attributes);

		return $instance->setRelations($this->relations);
	}
