Rails - Sep 2005 - Can multiple tables belong to a single parent?

I was struggling with some code today and realized that I have two  
tables belonging to one parent. Is this even possible? Say for  
instance I have a "categories" table. There''s also a
"pages" and an
"images" table. I''ve got something like this in my code:

class Category < ActionRecord::Base
   has_many :pages
   has_many :images
end

class Page < ActionRecord::Base
   belongs_to :category
end

class Image < ActionRecord::Base
   belongs_to :category
end

Is this even remotely valid, or have I been sitting in front of this  
computer for too long?!? Is there a smarter way to go about this sort  
of thing?

Draw an ER diagram of your DB and all will be clear. :-)

                   ------------
                   | category |
                   ------------
                    |        |
                   /|\      /|\
           -----------     ------------
           |  pages  |     |  images  |
           -----------     ------------

Looks OK to me.
