Hum, this slipped by.
But, luckily (??) hit me again:
Want to list ids associated with artists and show the ids in order.
The cd objects stringify to its id.
CD ISs: [% artist.cds.nsort.join( ', ' ) %]
This works if the artist has more than one CD. If they only have one
then I get:
CD IDs: id
Note the string "id".
Now, I if I do:
CD ISs: [% artist.cds.list.nsort.join( ', ' ) %]
That also works except for the one with a single CD which I then get:
CD IDs: HASH(0xb6fd444c)
So, what seems to only works is this:
CD ISs: [% as_list(artist.cds.).nsort.join( ', ' ) %]
Where as_list is:
sub { return ref( $_[0] ) eq 'ARRAY' ? shift : [shift] };
