如何修复模型启动方法无法正常工作的问题？

Question

protected static function boot()
    {
        parent::boot();
        self::creating(function ($model) {
            $model->unique_id = self::generateUniqueId();
        });

        self::deleting(function (Submission $submission) {
            Log::info('Deleting model:', ['model' => $submission]);
            dd($submission);
            // Delete all associated media
            $submission->clearMediaCollection('files');
            $submission->clearMediaCollection('images');
        });
    }

我在我的提交模型中有这个方法，创建时可以在每个新模型上工作，但删除不起作用，它只是删除模型，这不起作用

我的提交模型

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Log;
use Spatie\MediaLibrary\HasMedia;
use Spatie\MediaLibrary\InteractsWithMedia;
use Spatie\MediaLibrary\MediaCollections\File;

class Submission extends Model implements HasMedia
{
    use InteractsWithMedia, HasFactory;
    protected $fillable = [
        'unique_id',
        'user_id',
        'title',
        'description',
        'status',
    ];

    protected static function boot()
    {
        parent::boot();
        self::creating(function ($model) {
            $model->unique_id = self::generateUniqueId();
        });

        self::deleting(function (Submission $submission) {
            Log::info('Deleting model:', ['model' => $submission]);
            dd($submission);
            // Delete all associated media
            $submission->clearMediaCollection('files');
            $submission->clearMediaCollection('images');
        });
    }

    public static function generateUniqueId()
    {
        do {
            $uniqueId = str_pad(rand(0, 99999999), 12, '0', STR_PAD_LEFT);
        } while (self::where('unique_id', $uniqueId)->exists());

        return $uniqueId;
    }

    public function user()
    {
        return $this->belongsTo(User::class);
    }

    public function replies()
    {
        return $this->hasMany(SubmissionReply::class);
    }

    public function registerMediaCollections(): void
    {
        $this->addMediaCollection('files')
            ->useDisk('submissions')
            ->acceptsFile(function (File $file) {
                return in_array($file->mimeType, [
                    'image/jpeg',
                    'image/png',
                    'application/pdf',
                    'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
                    'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
                    'text/plain'
                ]);
            });

        $this->addMediaCollection('images')
            ->useDisk('submissions')
            ->singleFile()
            ->acceptsMimeTypes([
                'image/jpeg',
                'image/png',
                'image/jpg',
            ]);
    }
}

该问题可能是由于使用了

dd($submission)

导致的，它会停止执行并阻止媒体被删除。要解决此问题，请删除

dd()

并添加适当的日志记录，以确保触发删除事件并清除媒体。

如果您使用

forceDelete()

，则不会触发

deleting

事件。在这种情况下，请改为监听

forceDeleted

事件

self::forceDeleted(function (Submission $submission) {
    $submission->clearMediaCollection('files');
    $submission->clearMediaCollection('images');
});
