我有两个模特：账户：
<?php
namespace App\Models;
class Account extends \Illuminate\Database\Eloquent\Model
{
public function user()
{
return $this->belongsTo('\App\Models\User');
}
}
..和用户：
<?php
namespace App\Models;
class User extends \Illuminate\Database\Eloquent\Model
{
public function accounts()
{
return $this->hasMany('\App\Models\Account');
}
}
现在，当我执行以下操作时 - var_dump(\App\Models\User::find(1)->accounts()); - 我返回了Illuminate \ Database \ Eloquent \ Relations \ HasMany实例，但它没有't contain my accounts for that user'的ID . 我可以确认我的帐户表确实有几行，其中user_id设置为1.有什么我遵循文档，我看不到任何不同 .
如果有用的话，下面是 var_dump(\App\Models\User::find(1)->accounts()); 的输出：

使用正常的语法：
或者Dynamic properties：
但不要混淆两者 .
accounts()只是查询构建器的hasMany关系 . 帐户的实际对象由get()检索 . 动态属性缩短了为此任务编写所需的代码出于好奇，为什么要明确写出完全限定的命名空间？你可以使用
extends Eloquent
