I understand basic relationships in rails, but I’m confused on how to  
solve a particular problem.

I have posts and products. Both of which should be able to have  
multiple photos uploaded to them. So, posts have many photos and photos  
belongs to posts - BUT products have many photos too and photos belongs  
to products.

Products and posts have no relationship but they share the same child.

Is there a clean (non-hack) sort of way to solve this in Rails without  
creating a bunch of extra classes.
