Hello,

I’m trying to solve a problem without success. Look at:

I have 3 models (Recipe, Comments and User)

an Recipe has many Comments  
an User has many Comments  
an User has many Recipes

I tried to implement this using polymorphic associations with the  
Comment  
model. But the expected behavior needs to be: When a new comment is  
created  
i need to refer it in Recipe and Comments. To clarify i need to be able  
to  
search for one Recipe and use something like Recipe.comments to find  
comments!

Any suggestions?

Regards,  
Grabber.
