Invoking class method within class definition

ruby-talk
1

Hi,
    consider following code:

#!/usr/bin/env ruby
class Foo
  def self.bar
    puts "class method called"
  end

  def some_method
    Foo.bar # -----> self.bar will not work here
  end
end

foo = Foo.new
foo.some_method

although I can define the class method using "self", I have to use
class name to invoke the class method within the class. it would be
nice if I can invoke class method without explicitly using it's name,
so when I change my class name, I only need to change it in one place.
any way to do this?

Thanks!

def some_method
    self.class.bar
  end

will do what you want. Remember that inside #some_method, "self"
refers to the instantiated object, not the class itself.
