An attr_* in a constructor?

ruby-talk

Hi,

Can I not use an attr_* in a constructor? I am receiving a

`initialize': undefined method `attr_accessor'

<CODE>
class Whatever
  def initialize
    attr_accessor :log
    @log = 'whatever'
  end
end

Whatever.new
</CODE>

Thanks

The attr_* methods are private instance methods in Module, which means
that they are methods for modules and classes.

the initialize method is an instance method, in this case of the
Whatever class. Try:

class Whatever
  attr_accessor :log

  def initialize
      self.log = 'whatever'
    # or @log = 'whatever'
  end
end

Thanks Rick, I am having a little trouble with OO at the moment.
