Laravel Eloquent 提供了属性转换功能，允许您自动将属性转换为常见的数据类型。默认支持的转换类型有：integer, real, float, double, string, boolean, object, array, collection, date, datetime, 和 timestamp。

如你所见，自定义类类型不支持。此特性添加了这种支持，因此您可以自动序列化和反序列化自定义类。

安装

使用 Composer

$ composer require slruslan/laravel-eloquent-custom-casts --dev

使用方法

1. 创建一个 TEXT 类型的字段，用于存储数据。

2. 要启用特性，将 use Slruslan\CustomCasts\CustomCasts; 行添加到您的 Eloquent 模型类中。

例如

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Slruslan\CustomCasts\CustomCasts;

class Post extends Model
{
    use CustomCasts;

1. 将您的字段和要序列化的类名称添加到受保护的 $casts 数组中。

    protected $casts = [
        'geo_location' => \App\Services\CustomLocation::class,
        'another_custom_field' => \App\Services\AnotherCustomField::class
    ];

1. 您已经准备好使用模型了。以下是一个基本示例

    $post = Post::find(1);

    // For example, imagine we have an \App\Services\CustomLocation class,
    // that implements any custom logics and for some reasons
    // we have to store it in DB as it is.

    // Let's instantinate it.
    $location = new \App\Services\CustomLocation(55.9937441, 92.7521816);

    // And call some methods, imagine we have them there.
    $location->updatePosition();
    $location->callAPI();

    // After that, we want to save it in our post model.
    // We can just assign the value and call default save() method.
    $post->geo_location = $location;
    $post->save();

    // It's saved. Let's get a post again
    // and check the field class.

    $post = Post::find(1);

    var_dump($post instanceof \App\Services\CustomLocation);

    // Outputs:
    // bool(true)
