Handel now uses DBIx::Class instead of Class::DBI as the default ORM. Many thanks to the DBix::Class folk for all the support. Without the flexibility that DBIx::Class provides, Handel 1.0 would be a much less flexible.
For those who prefer working with Rose instead, Handel::Storage::RDBO 1.0 has also been released.
You can now add/remove columns from/to the default classes and schema with only a few lines of code.
If you already have an existing schema in your application, Handel can now use that instead of it's own.
Handel now uses an abstract storage layer for cart/order operations. The default layer is Handel::Storage::DBIC and a Handel::Storage::RDBO layer is also available. New storage layers may be written (XML, LDAP, SOAP, Amazon, Google, etc) and can be used by your Handel code with almost no code changes.
Handel now includes a Module::Starter module and scripts to quick get a custom cart/order system up an running and deploy the schema to an existing database.
To make the conversion to 1.0 a little less painful, 1.0 includes a few Compat modules allowing you used the old API with a new 1.0 install.
In addition to all of the new features and refactoring, Handel now has a plethora of tests and a 99% test coverage. That means that the code base is considered to be very stable and all new code has been accounted for.
The new version should be available on a CPAN mirror nearest you shortly. As always, you can find the latest version in the Subversion repository. If you need help, please join the mailing list or stop by #handel@irc.perl.org.
Happy Carting!

Once 1.0 is kicked out the door, I need to spend some time getting the RDBO storage layer up to date. Then, it's back to Mango.
]]>With any luck, I'll try and post about progress often.
]]>Through all of my tinkering with the Handel::Currency class to do conversions, formatting and integrate inflation into DBIx::Class, I kept feeling the urge to put some parts of it on CPAN because it felt like reusable code. During a few down days, I did just that. Thus, Data::Currency and DBIx::Class::InflateColumn::Currency were born.
During that process, I had a chance to clean up the Handel::Currency API into something more precise for non Handel users. The biggest change was that
So, for those using Handel 0.33, nothing is changing. When you upgrade to Handel 1.0, you can still use the Handel::Compat::Currency module if you like. For those of you using a recent version of Handel 0.99_xx, your code will have to change to use
I only feel slight bad about that. It is a developer release after all. :-)
]]>The dist includes the requisite storage, schema, and result classes needed to use Handel 1.0 with Rose::DB::Object classes instead of the DBIx::Class schema classes.
To use RDBO instead of DBIC, all you have to do is change the storage_class in your storage classes generated by the bootstrap:
package MyApp::Storage::Cart;
use strict;
use warnings;
BEGIN {
use base qw/Handel::Storage::DBIC::Cart/;
};
becomes:
package MyApp::Storage::Cart;
use strict;
use warnings;
BEGIN {
use base qw/Handel::Storage::RDBO::Cart/;
};
You will need to do this in the Cart, Cart::Item, Order, and Order::Item storage classes. At some point I will change the generation scripts to allow one to specify DBIC or RDBO during code generation.
Handel-Storage-RDBO-0.01_01 should be available on CPAN shortly, and requires Handel 1.0, which doesn't yet exist. Please use the latest code from the 1.0 branch for now until I get another dev release out the door:

]]>I still have to make Perl::Critic happy with the test suite (test labels). The L!0N lexicons need completed, and the demos still need fixed. This might possibly be the last dev release before 1.0.

module-starter --class=Module::Starter::Handel --module=MyProject \
