Yii2 块赋值

yii2 新增两种方式

1. 这种方式表字段少还好，如果表字段特别多，很反感这种写法。

$model = new User();
$model->name = 'james';
$model->age = 25;
$model->save();

2. 块赋值

1. 定义场景
public function scenarios()
{
  return [
    "login" => ["username"],
    "register" => ["username", "password"],
  ];
}

$user = new User();
$user->scenario = "login";
$user->attributes = $attr;
$user->save();

2. 通过规则
public function rules()
{
  return [
    [["username", "password"], "safe"]
  ];
}

$user = new User();
$user->attributes = $attr;
$user->save();
