此库提供了一个特性，可以混合到 Eloquent 模型中。这样做将支持填充关系。

要使用，首先在您的 composer 文件中引入

composer require jekferson/laravel-fillable-relations

然后，在您的代码中

<?php
namespace MyApp\Models;

use Illuminate\Database\Eloquent\Model;
use LaravelFillableRelations\Eloquent\Concerns\HasFillableRelations;

class Foo extends Model
{
    use HasFillableRelations;
    protected $fillable_relations = ['bar'];

    function bar()
    {
        return $this->hasOne(Bar::class);
    }
}

class Bar extends Model
{
    use HasFillableRelations;
    protected $fillable_relations = ['foos'];

    function foos()
    {
        return $this->hasMany(Foo::class);
    }
}

现在您可以填充关系，如下所示

$foo = new Foo(
    [
        'cuux' => 42,
        'bar' => [
            'id' => 42
        ]
    ]
);

或者可能是这样的

$foo = new Foo(
    [
        'cuux' => 42,
        'bar' => [
            'name' => "Ye Olde Pubbe"
        ]
    ]
);

也可以这样

$bar = new Bar(
    [
        'name' => "Ye Olde Pubbe",
        'foos' => [
            [
                'cuux' => 42
            ],
            [
                'cuux' => 1337
            ]
        ]
    ]
);

为了自动断开空关系，传递一个空数组

$bar->fill([
    'foos' => [] // Detach all foos
]);

$bar->save();

您可以使用 Laravel validator array rule 来保留传递给请求的空数组

class UpdateRequest extends FormRequest
{
    public function rules()
    {
        return [
            'foos' => [
                'array',
            ],
        ];
    }
}

然后在控制器中一行更新属性和关系

public function update(UpdateRequest $request, Bar $bar)
{
    $bar->fill($request->validated())->save();
}
