我需要从除users属性之外的users表中选择id和name属性。我试过这个：
$school_user = User::select('name', 'id')->get()->toArray();
但是当我将它打印到屏幕时，它会返回带有角色的数组。像这样：
Array
(
[0] => Array
(
[name] => Admin
[id] => 1
[roles] => Array
(
[0] => Array
(
[id] => 3
[name] => admin
[pivot] => Array
(
[user_id] => 1
[role_id] => 1
)
)
)
)
)
除了角色之外，是否只提供名称和ID属性的建议？
我的用户模型类（有点清理）：
<?php

角色模型：
<?php
class Role extends Eloquent {
/**
* The database table used by the model.
*
* @var string
*/
protected $table = 'roles';
protected $fillable = array('name');
protected $guarded = array('id');
/**
* Set timestamps off
*/
public $timestamps = false;
/**
* Get users with a certain role
*/
public function users()
{
return $this->belongsToMany('User', 'users_roles');
}
}
我很抱歉在例外情况下使用保加利亚语言
答案 0 :(得分：1)
查看代码时，运行只是不可能：
$school_user = User::select('name', 'id')->get()->toArray();
将roles附加到结果。
您应确保不向$appends属性添加任何内容，并且不在代码中的某处加载关系。您还应该确保没有实现自定义toArray()方法，以便在转换为数组时加载此关系。如果您确定不这样做，则应显示完整的代码和您的Laravel版本。
修改
您没有显示使用select或lists启动代码的位置，但是您在许多方法中加载了roles关系 - 例如isEmployee，{{1 }或isEmployee。这就是为什么在转换为数组时使用hasRole的原因。您可能希望编写自定义roles方法，以便在转换为数组时从结果集中删除toArray。
