If you want to populate your state dropdown based on what is there in the country dropdown, you have to use javascript. There is no other way.

I have referred some answers and got some gems to do such as acts_as_nested_set, or awesome_nested_set.. I want to know which will be best practices whether using gem or using javacsript?

The gems that you mention will be using javascript internally. In the original question you said that you want to use neither a gem nor javascript. Otherwise carmen-rails (github.com/jim/carmen-rails) is a very good gem for the purpose, much better than re-inventing the wheel.
