Hi,

I have these 3 models: City :name Product :name city_preference :city_id, :product_id, :min, :max

How do i create the associations between these tables? Best Greg

Have a look at the rails guide on ActiveRecord Associations at http://guides.rubyonrails.org. Also Getting Started, Debugging and the others if you have not already worked through them.

Also don't think about tables first, think about the real world objects you are modeling and what there relationships and attributes are. That will then allow you to define the tables and associations.
