Accessors: Problem in accessing an attribute of other class

Ruby
1

Hi,

I was practising accessors in ruby and came across the following
problem:

class Music

attr_accessor :song, :artist
def initialize
@song = “This never happened before”
@artist = “Paul McCartney”
end
end

class Sport < Music

attr_reader :player
attr_accessor :game, :gender
def initialize(player)
@player = player
@game = {:game1 => ‘Tennis’, :game2 => ‘Cricket’, :game3 => ‘F1’}
@gender = {:g1 => 'male, :g2 => ‘female’}
end
end

sp = Sport.new(‘Roger Federer’)
puts sp.player => outputs to “Roger Federer”
puts sp.game[:game1] => outputs to “Tennis”
puts sp.gender[:g1] => outputs to “male”
puts sp.song => outputs to “Nil” => I want to access the song attribute
of Music class so that it shows me the output as “This never happened
before”

Can anyone help so that I can access the attributes of other class?

Thanks,
Anukul

You forgot to call super from Sport#initialize.

Hi Anukul,

Sorry, but your classes don’t make any sense. There is no reason for
Sport to inherit from Music. Likewise, Sport shouldn’t have the
attributes player, game, and gender. Perhaps you should brush up on
Object Oriented programming before trying to learn ruby.
