What's the best action persistence technique for a Catalyst application?

use Storable;
...
sub auto {
    ...
    unless (...) { #ie don't do this if processing the login action
        my $formitems = freeze $c->request->body_parameters;
        my $freezer = $rs->update_or_create(
              {user => $c->user, formitems => $formitems} );
        # Don't quote me on the exact syntax, I don't use DBIx::Class
    }
    ...
    my $formitems = $c->request->body_parameters
                  || thaw $rs->find({$user => $c->user})->formitems
                  || {} ;
    # use formitems instead of $c->request->body_parameters from here on in
