Question

我的数据库中有3个表，categories，subcategories和childcategories。

子类别在删除时具有级联，因此每次我删除类别时，子类别也会被删除。子类别也一样。

我的问题是，他们所有人都可以拥有attributes，当我向子类别添加属性并删除类别时，他会删除所有内容，但不要删除子类别的属性。我已经尝试了雄辩的事件，一些在github ..中找到的软件包，但是没人管。

类别模型：

class Category extends LocalizedModel {

public $translatedAttributes = ['name'];
protected $fillable = ['slug','photo','is_featured','image'];
public $timestamps = false;

public function subs()
{
    return $this->hasMany('App\Models\Subcategory')->orderByTranslation('name', 'asc')->where('status','=',1);
}

public function attributes() {
    return $this->morphMany('App\Models\Attribute', 'attributable');
}

子类别模型：

class Subcategory extends LocalizedModel {

public $translatedAttributes = ['name'];
protected $fillable = ['category_id','slug'];
public $timestamps = false;

public function childs()
{
    return $this->hasMany('App\Models\Childcategory')->where('status','=',1);
}

public function category()
{
    return $this->belongsTo('App\Models\Category')->withDefault(function ($data) {
        foreach($data->getFillable() as $dt){
            $data[$dt] = __('Deleted');
        }
    });
}

public function attributes() {
    return $this->morphMany('App\Models\Attribute', 'attributable');
}

}

子类别模型：

class Childcategory extends LocalizedModel{

protected $cascadeDeletes = ['attributes'];
public $translatedAttributes = ['name'];
protected $fillable = ['subcategory_id','slug'];
public $timestamps = false;

public function subcategory()
{
    return $this->belongsTo('App\Models\Subcategory')->withDefault(function ($data) {
        foreach($data->getFillable() as $dt){
            $data[$dt] = __('Deleted');
        }
    });
}

public function products()
{
    return $this->hasMany('App\Models\Product');
}

public function setSlugAttribute($value)
{
    $this->attributes['slug'] = str_replace(' ', '-', $value);
}

public function attributes() {
    return $this->morphMany('App\Models\Attribute', 'attributable');
}

}
