此 trait 允许你在 Laravel 应用程序中检查一个模型是否拥有其他模型。

安装

简单运行

composer require santigarcor/laravel-ownable

然后，你需要在想要检查是否拥有其他模型的模型中使用 OwnsModels trait。

<?php

use Ownable\OwnsModels;
use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    use OwnsModels;
}

你现在可以使用它了。

使用方法

<?php

use Ownable\OwnsModels;
use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    use OwnsModels;
}

class Video extends Model
{
}

$user = User::first();
$video = Video::first();

// Check If the user owns the video
if ($user->owns($video)){}

// Check If the user doesn't owns the video
if ($user->doesntOwn($video)){}

// Check If the user owns the video but the foreign key is the_user_id
if ($user->owns($video, 'the_user_id')){}

如果出于某种原因，所有权检查需要更复杂的逻辑，你可以在你的拥有权对象内部实现 Ownable 接口，然后你可以在 isOwnedBy 方法中定义自定义逻辑。当此方法被调用时，调用 owns 方法的对象被作为属性传递给 isOwnedBy 方法。

<?php

use Ownable\OwnsModels;
use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    use OwnsModels;
}

use Ownable\Contracts\Ownable;

class Video extends Model implements Ownable
{
    public function isOwnedBy($owner): bool
    {
        if ($owner instanceof User) {
            return $this->someRelationship->user_id == $owner->id;
        }

        return false;
    }
}

$user = User::first();
$video = Video::first();

// Then you can simply call the owns method on the user and it will work.

// Check If the user owns the video
if ($user->owns($video)){}

// Check If the user owns the video but don't use the ownable logic, instead the regular one with the foreign key.
if ($user->owns($video, null, false)){}
