Hi:

I'm writing a class where I need to know the class's name inside a class
method:

class MyClass

  def instance_method
    puts self.class.name # => "MyClass"
  end

  def self.class_method
    self.class.name # => Undefined
    how can I get class.name here?
  end

end

Thanks,
Eric

Or even just

class MyClass
def self.class_method
   name
end
end

Hereby I grant you the first official "useless self" award of Rubyland.
:wink:
