除了角色属性，我只需要从users表中选择id和name属性。我试过这个：
$school_user = User::select('name', 'id')->get()->toArray();
但当我把它打印到屏幕上时，它会返回带有他的角色的数组。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
)
)
)
)
)
有没有建议只获取除角色之外的名称和id属性？
这里有我的用户模型类（有点干净）：
<?php

/**

角色模型：
<?php

*/
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');
}
}
很抱歉在例外情况下使用保加利亚语
查看代码，不可能只运行：
$school_user = User::select('name', 'id')->get()->toArray();
将CCD_ 1附加到结果中。
您应该确保没有向$appends属性添加任何内容，也没有在代码中的某个位置加载关系。您还应该确保没有实现在转换为数组时加载此关系的自定义toArray()方法。如果你确定你没有，你应该显示完整的代码和你的确切的Laravel版本。
编辑
您没有显示在哪里使用select或lists启动代码，但是您可以用许多方法加载roles关系，例如isEmployee、isEmployee或hasRole。这就是在转换为数组时使用roles0的原因。您可能需要编写自定义toArray方法，以便在转换为数组时从结果集中删除roles。
