我的代碼:Laravel - 非法偏移類型的hasMany()
$user = User::where('uid', $user_id)->with('groups.sub_groups')->firstOrFail();
return $user;
在我的用戶模型:
return $this->hasMany('group');
在我的組型號:
return $this->hasMany('sub_group');
現在的堆棧跟蹤給我錯誤:
Illegal offset type
Illuminate/Database/Eloquent/Relations/HasOneOrMany.php
$foreign = $this->getPlainForeignKey();
// First we will create a dictionary of models keyed by the foreign key of the
// relationship as this will allow us to quickly access all of the related
// models without having to do nested looping which will be quite slow.
foreach ($results as $result)
{
$dictionary[$result->{$foreign}][] = $result;
}
更新
去除.sub_group
不會返回一個錯誤。
// works
$user = User::where('uid', $user_id)->with('groups')->firstOrFail();
