创建用户。

我在帐户模型中使用注册方法来创建用户。

$data['account_username'] = 'unique_username';
$data['account_password'] = 'pass';
$data['account_email'] = '[e-mail]';

$account = self::forge($data);
$account->account_level = new Model_AccountLevel();
$account->account_level->level_group_id = 3;
$account->save();
$account_id = $account->account_id;

我得到了这个错误。

分配的关系必须是数组或空，给定的关系 account_level 的值无效。

如何插入相关表？我的代码有什么问题？

【问题讨论】：

account_level 被定义为 has_many.. 这意味着它必须是一个集合。 $account->account_level[] = new Model_AccountLevel();。追加，不要设置。

【参考方案1】：

您的account_level 关系是has_many，这意味着在访问它时您需要像访问数组一样访问它。 ORM 期望 this 的值是一个数组，因此直接将模型分配给它是无效的。

你想做的是：

$account->account_level[] = new Model_AccountLevel(['level_group_id' => 3]);

（在构造函数中使用数组，因为我个人觉得它更整洁，但不是必需的）
