		$table->increments('id');
		// parent id
        $table->integer('parent_id')->unsigned()->nullable();
        // depth path consisting of models id
        $table->string('path');
        // depth path consisting of models alias
        $table->string('real_path')->unique();
        // alias field
        $table->string('alias')->unique();
