This is RPC, not REST. Not that there's anything wrong with that.

It sounds like what you want to write is a Controller that proxies class
methods to a URI. For example, you write a class like this:

package Foo;

sub create { my ($class, $username, $password) = @_; ... }
sub delete { my $self = shift; $self->delete }
sub foo { my ($self, $quux, $value_for_42) = @_; ... }

sub fetch_existing { my ($class, $id) = @_ }

...
1;

Then you write a controller like this:

package MyApp::Controller::Foo;
use base 'The::Thing::You're::Writing';

__PACKAGE__->config(
class => 'Foo',
fetch_existing => 'fetch_existing',
new_instance => 'create',
methods => {
create => ['username', 'password'],
delete => [],
foo => ['quux', '42'],
},
);
1;

Then you have actions like:

/foo//create/<username>/<password>
/foo/<id>
/foo/<id>/foo/<quux>/<value for 42>
/foo/<id>/delete

In your configuration, an option would be available to REST-ify certain
parts of the RPC interface:

rest => {
create => 'create',
get => 'fetch_existing',
delete => 'delete',
update => 'update',
}

Then you would have the /foo and /foo/<id> REST endpoints do the same
thing as the RPC calls.

Anyway, making this specific to DBIx::Class sounds like a waste of time.
