If it does, a warning is issued if they are enabled. No big deal, but not clean either. -The method `redefine_method` prevents such a potential warning, removing the existing method before if needed. Rails uses it in a few places, for instance when it generates an association's API: - -```ruby -redefine_method("#{reflection.name}=") do |new_value| - association = association_instance_get(reflection.name) - - if association.nil? || association.target != new_value - association = association_proxy_class.new(self, reflection) - end - - association.replace(new_value) - association_instance_set(reflection.name, new_value.nil? ? nil : association) -end -``` +The method `redefine_method` prevents such a potential warning, removing the existing method before if needed.
