New stuff in DBIx::Class::Helpers

I just released a new version of DBIx::Class::Helpers and it has two new components: DBIx::Class::Helper::ResultSet::ResultClassDWIM and DBIx::Class::Helper::Schema::GenerateSource.

🔗 Helper::ResultSet::ResultClassDWIM

This component solves an issue I’ve seen both by myself and with my coworkers; it’s too hard to remember/type the following:

my $rs = $schema->resultset('Foo')->search($q, {
   result_class => 'DBIx::Class::ResultClass::HashRefInflator',

So I wrote this component which will let you generically write:

my $rs = $schema->resultset('Foo')->search($q, {
   result_class => '::HashRefInflator',

or use the specially hardcoded:

my $rs = $schema->resultset('Foo')->search($q, {
   result_class => '::HRI',

Handy right?

🔗 Helper::Schema::GenerateSource

This component is a little more unusual. The idea is to take care of some of the issues I mentioned here. It doesn’t solve everything due to some design issues in DBIx::Class, which I hope to take care of soon. Basically the idea is that instead of the boilerplate files that you get when you use DBIx::Class::Helper::Row::SubClass, you can instead just do the following in your schema:

package Foo::Schema;


# ...

__PACKAGE->generate_source(User => 'MyCompany::Result::User');


The main issue is that even though this correctly associates a new source to the schema, you cannot currently add relationships to the source. I’ll make another post when I fix that, but I doubt I’ll get it into the next release of DBIx::Class.

In other news I’m doing some pretty sweet stuff with the SQL generation code in DBIx::Class and I hope it will be ready for the next release. I’ll post more when that’s released.
