Now I try to overwrite a class's private class method(ActiveRecord::Base)，but it seems doesn't work，look this scenario：
1. module Dummy 2. private 3. def method_has 4. puts "new methods has" 5. end 6. 7. def method_not_has 8. puts "method not has" 9. end 10. end
1. class Sample 2. class<<self 3. private 4. def method_has 5. puts "method has" 6. end 7. end 8. end 9. 10. Sample.extend Dummy 11. 12. Sample.send(:method_not_has)=>"method not has" 13. 14. Sample.send(:method_has)=>"method has"
but what I want is method_has return the string "new method has"，How? Why?
