It works! Thanks very much!

I understand, now that you pointed it out (!), what I was doing wrong. The player_data_currs relationship is referring to a resultset because has_many relationships always refer to resultsets. So, although there is only a single record in $player_static->player_data_currs->all, I need to get the single object/record from the resultset and then call team_libl on it.

$player_static->player_data_currs->all->team_libl->id doesn't work either because, again, I am calling team_libl on a resultset not on a single object.

I see now that if I go the other way, from PlayerDataCurr to PlayerDataStatic through a belongs_to relation in PlayerDataCurr, I can accomplish what I'm after much more easily. I suppose this is because a belongs_to links to an object not a resultset. Is that right?

So, in PlayerDataCurr, I have this: 
__PACKAGE__->belongs_to(
  "id_static",
  "LIBL::Schema::Result::PlayerDataStatic",
  { id => "id_static" },
  {
    is_deferrable => 1,
    join_type     => "LEFT",
    on_delete     => "CASCADE",
    on_update     => "CASCADE",
  },
);

And then this works: 
my $roster_rs = $player_curr_model->search(
    {
        team_libl => { '!=' => undef },
    },
    {
        prefetch => [ 'id_static', ],
    },
);

foreach my $player_curr ( $roster_rs->all ) {
    say $player_curr->team_libl;
}

(I apparently have only a very fuzzy grasp of the difference in relationships. I have struggled over DBIx::Class::Relationship but never really understood it.)

Thanks again for your help. Your succinct explanation taught me something that I could not discover on my own.
