from Laravel 5.2, Global Scope is available:

class Article extends Post
{
    protected $table = 'posts';

    protected static function boot()
    {
        parent::boot();

        static::addGlobalScope('article', function (Builder $builder) {
            $builder->where('type', 'article');
        });

        static::creating(function ($article) {
            $article->type = 'article' 
        }); 
    }
}

where type = 'article' is added to all query of Article just like SoftDeletes.

>>> App\Article::where('id', 1)->toSql()
=> "select * from `posts` where `id` = ? and `type` = ?"

Actually laravel provide SoftDeletes trait using this feature.
