Rails - Apr 2006 - 3 models -> 1 image

Hello, I have 3 models (Galery, Product, News) which all have 0 or 1 
Image

I don''t understand what the relationship between the 3 models and the 
Image model should be.

I might goes to Galery has_one Image, Product has_one Image and News 
has_one Image but I presume that active record will rely on Image model 
having a foreign key related to only one owner model (eg. 
Image.galery_id), which can''t be the case.

Any hint appreciated, thank you

How about having your Gallery, Product, and News belongs_to Image?

Doesn''t sound natural for me...

I''ve found this thread (http://www.ruby-forum.com/topic/61327) and the 
last answer close to my feelings about belongs_to.

I don''t know if this solution is the right one.

Any thought about this ?
