What is the best way to include traits in the model?
提问by user1692333
I have my own user model which requires some permissions. I created /app/models/Permissions.phpinside which is trait. Now i need to use it in /app/models/MyUser.php. How to do this in Laravel style?
我有自己的用户模型，需要一些权限。我在/app/models/Permissions.php里面创建了trait。现在我需要在/app/models/MyUser.php. 如何在 Laravel 风格中做到这一点？

I would do that this way.
我会这样做。
1.Model
一、型号
<?php namespace Models;
// app/models/MyUser.php
class MyUser extends \Eloquent {
use \Traits\Permissions;
/* ... */
}
2.Create Trait itself
2.创建 Trait 本身
<?php namespace Traits;
// app/traits/Permissions.php
trait Permissions {
/* ... */
}
3.Modify composer.json and add this into classmap
3.修改composer.json，将其加入classmap
"app/traits",
4.In order Laravel could autoload traits you need to dump autoload file and generate new one
4.为了让 Laravel 可以自动加载特性，你需要转储自动加载文件并生成新的
php artisan dump

Thank you for the example Andreyco.
谢谢你的例子 Andreyco。
To complement this helps to add a function to the model itself. For example, this would be entered in the Trait. In step 2
作为补充，这有助于向模型本身添加一个功能。例如，这将被输入到 Trait 中。在步骤 2
public function scopeGetMyFunction($query, Request $request)
{
//more code....
$query->get();
}
and so we can use it as part of the Model on the controller.
因此我们可以将其用作控制器上模型的一部分。
public function index(Request $request)
{
$models = \App\Models\User::getMyFunction($request);
return $models;
}
