Almost there, you should be able to use:

  $myobj->user->{login_name};

The 'has_a' creates a method called 'user' (rather than a property, as
you were trying to access) that retrieves the relevant user object for
you.

Note that it's probably safer to do something like:

 my $user = $myobj->user;
 my $login_name = ( $user ) ? $user->{login_name} : 'Anonymous';

just in case $myobj doesn't have 'user_id' defined.

Note: Object relationships are getting rewritten, but it will
(hopefully) have much the same interface.
