不创建类对象 - Ruby on Rails

Question

I am trying to create a User class in Ruby On Rails App, and when I call NETWORKING::User.new(1,"Testing") , it returns *** ArgumentError Exception: wrong number of arguments (2 for 0)

Not sure why?

class NETWORKING::User 
   mattr_writer :id, :name

 class << self

    def initialize(id, name)
        @id = id
        @fullname = name

    end

end
end

Answer 1

class << self serves no purpose here except to break your code. Remove it:

class NETWORKING::User 
  attr_accessor :id, :name

  def initialize(id, name)
    @id = id
    @fullname = name
  end
end
