Subject: Simpler refactor?

Hi,

As I continue learning to program, I am finding things I think can
probably be
done in a better way.  The following code seems like something
programmers must run into all the time and I am wondering if there is a
better way to write the code in this situation (it seems very repetitive
to me).  I'm having fun and trying to get better at this....

          if !session[:subject_id].blank?
         @subject_id = session[:subject_id]
    end

    if !session[:book_id].blank?
      @book_id = session[:book_id]
    end

    if !session[:chapter_id].blank?
      @chapter_id = session[:chapter_id]
    end

    if !session[:section_id].blank?
      @section_id = session[:section_id]
    end

    if !session[:subsection_id].blank?
      @subsection_id = session[:subsection_id]
    end

    if !session[:minisection_id].blank?
      @minisection_id = session[:minisection_id]
    end

Is there a better way??

Thanks...

Dave
