[XP] Inheritance

[Victor Sant]

Another thing that you might be careful: don't use aliases with methods that exists only on the parent classes.

#Wrong

Code:

class Parent_Class
  def method(*args)
     #anything
  end
end
class Child_Class < Parent_Class
  alias old_method method
  def method(*args)
    old_method(*args)
     #anything
  end
end

This will return the stack level too deep error if you press F12.

Instead use the super

Code:

class Parent_Class
  def method(*args)
     #anything
  end
end
class Child_Class < Parent_Class
  def method(*args)
    super(*args)
     #anything
  end
end
