## Usage

### Specifying attributes as codes

There are cases you want to store 'named codes' instead artificial keys.
Codes make sense for stable references and better readability of the raw data.

There are several options to specify an attribute as a code:
  1. Attribute is a code. There is no associated object involved, but simple I18n translation of the code
  1. Attribute is a code. There exists a code object that is looked up on access.
  1. Attribute is a code. There exists an AR code object that is looked up through AR association.

#### Lookup through I18n

Example

    class Person
      iclude CodeBox::CodeAttribute

      attr_accessor :nationality_code
    end

The include will create the following methods in Person:

  #nationality Will return the nationality looked up through I18n on key: 'activerecord.values.person.nationality_code.de: Germany', where de would 'de' the nationality code.



#### Lookup through code object

Example

    class Person
      iclude CodeBox::CodeAttribute

      attr_accessor :nationality_code, :lookup_type => :lookup
    end

    class Code::Nationality
      attr_accessor :code, :name

      def lookup(code)
        return the correct Code::Nationality for the passed code
      end
    end

The include will create the following methods in Person:

  #nationality Will return the nationality looked through lookup on the associated code object.


#### Lookup through associated AR Code Object
