Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object

Instead of defining a whole lot of attr_accessor, let’s be smart about templates, right ?

def method_missing(method, *args, &block)
  if method =~ /(.+)=$/
    # Method 1: works but the attr_accessor would be set on all instances
    # Which is not good
    #
    # self.class.__send__(:attr_accessor, $1.to_sym)
    # self.__send__(method, *args, &block)

    # Method 2: Just set the instance variable, works better
    self.send(:instance_variable_set, "@#{$1.to_sym}", *args)
  end
