attr_accessor for array?

Question

I want to have an array as a instance variable using attr_accessor.

But isn\'t attr_accessor only for strings?

How do I use it on an ar

Answer 1

It works for me:

class Foo

  attr_accessor :arr

  def initialize() 
    @arr = [1,2,3]
  end

end

f = Foo.new
p f.arr

Returns the following

$ ruby /tmp/t.rb
[1, 2, 3]
$
