You could use:

class Invitation
  attr_reader :id, :date, :user, :text, :email

  def Invitation.withId(id)
    return self.new(id)
  end

  def Invitation.withAll(id, date, user, email, text)
      return self.new(id, date, user, email, text)
  end

  def initialize(id = 0, date = '', user = '', email = '', text = '')
    super()
    @id = id
    @date = date
    @email = email
    @user = user
    @text = text
  end
end

then:

invitation = Invitation.withId(1)

or with all params.
