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?

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.
