As described here http://guides.rubyonrails.org/active_record_querying.html#eager-loading-associations
I think what you want is something like
products = Product.includes(:category)
This will eager load the category association when you load the Product objects. You must specify the inverse relationship (in product.rb you must have belongs_to :category) for this to work.

Hello,
I have a products table that is related to category.
category has many products.
How do I query the products to also include the category?
Once I do this, how to I show the category data in my template?
Thanks--
