Include column from a :belongs_to association?

Product model

Class Product < ActiveRecord::Base  
    belongs_to :product_group  
end

ProductGroup model 

Class ProductGroup < ActiveRecord::Base  
    has_many :products  
end

Is the a way to declare a shortcut for product.product_group.name as product.name, and have product_group.name included in product.to_json as name whenever a Product is converted to json?

To answer your first question: create a name method in Product

def name
  product_group.name
end

As for your second question, you can customize as_json, also in your Product model. Something like this should work.

def as_json(options = {})
  super.merge({ name: name })
end
