Streamline Your Laravel Models with Stringable Attributes

Laravel's AsStringable Type converter is a powerful tool that significantly enhances the way you handle string properties in your Eloquent model. By converting string properties to Stringable objects, you can access a large number of string manipulation methods to write cleaner and more expressive code.

This method is especially useful for content-intensive applications where string operations are frequent, helping to keep the controller and view tidy.

use Illuminate\Database\Eloquent\Casts\AsStringable;

class Post extends Model
{
    protected function casts(): array
    {
        return [
            'title' => AsStringable::class,
            'content' => AsStringable::class
        ];
    }
}

Here is a practical example of a content management system:

<?php namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Casts\AsStringable;

class Article extends Model
{
    protected function casts(): array
    {
        return [
            'title' => AsStringable::class,
            'content' => AsStringable::class,
            'meta_description' => AsStringable::class
        ];
    }

    public function getSnippetAttribute()
    {
        return $this->content
            ->stripTags()
            ->words(30, '...');
    }

    public function getUrlPathAttribute()
    {
        return $this->title
            ->slug()
            ->prepend('/articles/');
    }

    public function getFormattedContentAttribute()
    {
        return $this->content
            ->markdown()
            ->replaceMatches('/\@mention\((.*?)\)/', '<a href="https://www.php.cn/link/2fc02e925955d516a04e54a633f05608">@</a>')
            ->replace('[[', '<mark>')
            ->replace(']]', '</mark>');
    }

    public function getSeoTitleAttribute()
    {
        return $this->title
            ->title()
            ->limit(60);
    }
}

$article = Article::find(1);
// 直接访问 Stringable 方法
dd($article->title->title());
dd($article->content->words(20));

// 使用计算属性
dd($article->snippet);
dd($article->url_path);
dd($article->formatted_content);
