I think there's a tiny misunderstanding the SQL code seems to be ok. It
lists a list of decades to choose from. I've tried the above SQL code
with SQLplaylist and DatabaseQuery and same there. Both return the
decades list and SQLplaylist throws an error (only once instead of
twice) but it also starts the playlist (which my plugin doesn't).
So the problem/error comes when I try to act on one of these values
(execute).
Since the logs show that the -getNextDynamicPlayListTracks- function
isn't even called yet (the error happens before) here's the content of
the -getDynamicPlayLists- function for the 'rated by decade' playlist:
Code:
--------------------
sub getDynamicPlayLists {
my ($client) = @_;
my %result = ();
my %playlist3 = (
'name' => 'Rated - by DECADE',
'groups' => [['Ratings Light ']]
);
my %parameter2 = (
'id' => 2, # A number between 1-10
'type' => 'custom',
'name' => 'Select decade',
'definition' => "select cast(((tracks.year/10)*10) as
int),case when tracks.year>0 then cast(((tracks.year/10)*10) as int)||'s' else
'Unknown' end from tracks where tracks.audio=1 group by
cast(((tracks.year/10)*10) as int) order by tracks.year desc"
);
# PL3
my %parametersPL3 = (
1 => \%parameter2
);
$playlist3{'parameters'} = \%parametersPL3;
$result{'ratingslight_rated-by_decade'} = \%playlist3;
return \%result;
}
--------------------
Did I screw something up in there?
