Ruby Build an Address Book in Ruby Class Design Initializing and Calling Methods

inquiring about Address Book challenge class design

I am inquiring about the way to complete the task for this challenge the way that Mr. Seifer does on his video. I set the @ address variable to = [ ] in initializing and set a method for add_address underneath. What more does this challenge need to be completed?

address.rb 
class Address
  attr_accessor :kind, :street_1, :street_2, :city, :state, :postal_code

  def initialize(kind, street_1, street_2, city, state, postal_code)
    @address= []

     def add_address(kind, street_1, street_2, city, state, postal_code)
    address = Address.new
    address.kind = kind
    address.street_1 = street_1
    address.street_2 = street_2
    address.city = city
    address.state = state
    address.postal_code = postal_code
    addresses.push(address)
  end

  end

  def to_s(format = 'short')
    address = ''
    case format
    when 'long'
      address += street_1 + "\n"
      address += street_2 + "\n" if !street_2.nil?
      address += "#{city}, #{state} #{postal_code}"
    when 'short'
      address += "#{kind}: "
      address += street_1
      if street_2
        address += " " + street_2
      end
      address += ", #{city}, #{state}, #{postal_code}"
    end
    address
  end
end

Hi William,

The challenge question seemed to be vague and not clear to me. You can create new variable called address after class Address on the bottom.

We already have this in the challenge part, you don't have to change anything on initialize method. Let's take a look at initialize, you notice @kind, @street_1, @street_2, etc. That parts tell us to add address variable with Address class. 

class Address
  attr_accessor :kind, :street_1, :street_2, :city, :state, :postal_code

  def initialize(kind, street_1, street_2, city, state, postal_code)
    @kind = kind or ''
    @street_1 = street_1 or ''
    @street_2 = street_2 or ''
    @city = city or ''
    @state = state  or ''
    @postal_code = postal_code or ''
  end

  def to_s(format = 'short')
    address = ''
    case format
    when 'long'
      address += street_1 + "\n"
      address += street_2 + "\n" if !street_2.nil?
      address += "#{city}, #{state} #{postal_code}"
    when 'short'
      address += "#{kind}: "
      address += street_1
      if street_2
        address += " " + street_2
      end
      address += ", #{city}, #{state}, #{postal_code}"
    end
    address
  end
end

Example (add this on the bottom)

address = Address.new("Town", '342 Washington Road.', 'Crossroad Rd', 'Washington', 'DC', '45015')

Hope that helps :)

I guess we speak different languages because, I think that your answer is a little wordy. To be clear I wanted to know if the challenge called for me to write the address = address.new and add @address = [ ]. I gather that you are implying that I should not add anything new except address = address.new(.........) at the bottom of what? The initialize places or after the end or the bottom of the whole code......
