This is what I do:

sub get_rs {
    my $self =3D shift;

    return $self->{_resultset} if $self->{_resultset};

    # get stash
    my $stash =3D $self->form->stash;

    my $rs;
    if ( ( my $c =3D $stash->{context} ) && $self->model ) {
        $rs =3D $c->model( $self->model )
            or croak "\$c->model('@{[$self->model]}') does not exist\n";
    }
    elsif ( $stash->{schema} && $self->resultset ) {
        $rs =3D $stash->{schema}->resultset( $self->resultset )
            or croak "Resulset '@{[$self->resultset]}' could not be
loaded.";
    }
    else {
        my $msg
            =3D 'need a Catalyst context or a DBIC schema in the stash'
            . ' and the respective model or resultset'
            . ' parameter in the form config file.';
        warn "@{[__PACKAGE__]}: $msg\n";
        $self->return_error($msg);
        return 0;
    }
    return $self->{_resultset} =3D $rs;
}
