Default format for Date and update/create date on DB

Hello,

I've changed the default date format in my envornment.rb:

ActiveSupport::CoreExtensions::date::Conversions::DATE_FORMATS.merge!(:default => '%d/%m/%Y')

Now I can display my database date rows with the .to_s and they appear as expected: day,month,year.

But the dates in the database are wrong from the entered ones.

I've spent some time searching through the web/forums and all that I've found are really difficult and hard solutions to solve this problem.

There's no automatic conversion from default format to database format ?

user format: dd/mm/yyyy database format: yyyy-mm-dd

what I get in the database is yyyy-dd-mm

And my :db format is ok: :db=>"%Y-%m-%d"

ActiveSupport::CoreExtensions::date::Conversions::DATE_FORMATS => {:rfc822=>"%e %b %Y", :number=>"%Y%m%d", :short=>"%e %b", :db=>"%Y-%m-%d", :long=>"%B %e, %Y", :long_ordinal=>#<Proc:0x011a830c@/Users/montx/.gem/ruby/1.8/gems/activesupport-2.2.2/lib/active_support/core_ext/date/conversions.rb:11>}

thanks!
