3 models -> 1 image


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

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 ?
