gem install aws-s3
Before you can do anything, you must establish a connection using Base.establish_connection!. A basic connection would look something like this:
AWS::S3::Base.establish_connection!(:access_key_id => ‘abc’,
:secret_access_key => ‘123′
)
Buckets are containers for objects (the files you store on S3). To create a new bucket you just specify its name.
AWS::S3::Bucket.create(’bucket_name’

You can format Date field by using strftime function
example :
Time.now()
=> Wed Dec 12 15:48:59 +0530 2007
Time.now().strftime(”%d/%m/%y %H:%M” => “12/12/07 15:50″
Here’s the (shortened) table for strftime.
%a weekday name.
%A weekday name (full).
%b month name.

%c date and time (locale)
%d day of month [01,31].
%H hour [00,23].
%I hour [01,12].
%j day of year [001,366].
%m month [01,12].
%M minute [00,59].

Fallback for non JavaScript enabled browsers can be specified by using the :action methods in the :html option.
