问题
I'm having problem with the date format of rails. It seems to me that the default Date Format is dd/mm/yyyy. How am I gonna change it to something like mm/dd/yyyy?
I read somewhere that ActiveSupport gem can handle this but I don't how it works.

Put following line in your enviroment.rb
Date::DATE_FORMATS.merge!(:default => "%m/%d/%Y")
and try
Time.now.to_date.to_s
On you rails console

You can add the file into the config/initializers folder having name i.e. (date_time_formats.rb). Simply add following line to the file.
Date::DATE_FORMATS[:default] = '%m/%d/%Y'
As per requirement you can change date format.
