Override attr_accessor setters in Ruby

• 
  

  class Rooster
    attr_accessor :name
    
    def initialize( name )
      self.name = name
    end
    
    def name=( some_name )
      self.name = "Funktified"
    end
  end
  
  r = Rooster.new( 'Freebird' ) # name is now 'Freebird'
  r.name = 'Tweety'
  puts r.name

• Result/Output
  
  Funktified
• Explanation
  You can use:
  
  

    def attribute=( someval )
    end
  

  
  
  to override a built-in Ruby setter method.

That's retarded. Use attr_accessor, which creates a getter AND setter.

Yea, I was fog-brained last night when I posted. My point was actually that you can override the built-in setter provided by Ruby using the = sign. I changed the post to reflect...
