Answer 1

You need to define the relationship on both models.
class User < ActiveRedord::Base
has_many :addresses, class_name: 'CustomerAddress', foreign_key: 'customer_id'
end
class Address < ActiveRecord::Base
belongs_to :user, foreign_key: 'customer_id'
end

Answer 2

Add a #current_customer method to your ApplicationController that return a Customer-instance instead of a User-instance:
class ApplicationController
#…
private
def current_customer
current_user && Customer.find_by_id(current_user.id)
end
end
then change your code like this:
class My::Account::AddressesController < MyController
def index
#addresses = current_customer.addresses
end
def new
#address = current_customer.addresses.new
end
#…
end
