ruby on rails - Change default date format to %Y%m%d%H%M%S -

i'm using rails 3 , want change default date format of created_at , updated_at date when save them db.

default date format %y-%m-%d %h:%m:%s, %y%m%d%h%m%s

where should change format? i'm trying create time_formats.rb in initializer folder.

here content:

class timeformats   time::date_formats[:db] = "%y%m%d%h%m%s"   time::date_formats[:default] = "%y%m%d%h%m%s" end 

this not work. there can me? thank you.

the time , date formats define in initializers apply when converting them strings in ruby. formats you've defined used time.now.to_s(:default).

i don't recommend (nor aware of way how) change how dates stored in database. should let database store them default, change how formatted in views using .to_s(:format) defined in initializers.
