Update FK_ID at validation/save time in activerecor

I have:

class Customer < ActiveRecord::Base
belongs_to :Customer_Type

class Customer_Type < ActiveRecord::Base
has_many :Customers

Is there a built-in way to auto populate customer_type_id
based on the “Human name” of the Customer_Type_ID?

c = Customer.new( :name => “John D.”, :customer_type_name =>
“Wholesale” )

c[:Customer_Type_ID] == 10 (if 10 is the id for the “Wholesale”

customer type)

ActiveRecord questions are better placed on the Rails mailing list,
but here’s a hint:

type = CustomerType.find_by_name(“Wholesale”)
