Changing sort order of a playlist depending on the day of the week.

[ladywhiskers]

I have a playlist that I want to refresh tracks every Monday (which is working), and then sort differently each day of the week (which doesn't seem to be working). Can someone see where I am going wrong?

/**
  * Collect favorite tracks that have not been listened to for a long time and added more than a month ago.
  * Updates daily
  */
 function updateHeardLikedandForgotten(){
    let recentTracks = RecentTracks.get(10000); 
    let savedTracks = Source.getSavedTracks();
    let bannedTracks = Source.getPlaylistTracks ('banned', '4Ep4JuDSqaIvd2OzraWRSt', '');
    let playlistTracks = Source.getTracks([
      { name: 'heard,liked, then forgotten', id: '7BpAuAyoNGmEu3OLC65aCN'}
      ]);

  if (Selector.isDayOfWeek('monday')) { 
    Filter.removeTracks(savedTracks, recentTracks);
    let startDate = new Date('2006-01-01');
    let endDate = Filter.getDateRel(30, 'endDay');
    Filter.rangeDateAbs(savedTracks, startDate, endDate);
    Selector.keepRandom(savedTracks, 200);
    Order.sort(savedTracks, 'features.acousticness','desc');
    Filter.removeTracks (savedTracks,bannedTracks)
        Playlist.saveWithReplace({
        id: '7BpAuAyoNGmEu3OLC65aCN',
        name: 'heard, liked, then forgotten',
        tracks: savedTracks,
    })    
    } else {
      if (Selector.isDayOfWeek('tuesday')) {
        Order.sort(playlistTracks, 'features.danceability','asc');
      } else if (Selector.isDayOfWeek('wednesday')) {
        Order.sort(playlistTracks, 'features.valence', 'desc');
      } else if (Selector.isDayOfWeek('thursday')) {
        Order.sort(playlistTracks, 'features.tempo','asc');
      } else if (Selector.isDayOfWeek('friday')) {
        Order.sort(playlistTracks, 'features.key', 'desc');
      } else if (Selector.isDayOfWeek('saturday')) {
        Order.sort(playlistTracks, 'artist.populatrity','desc');
      } else {
        Order.sort(playlistTracks, 'features.danceability','asc');
      }
      Filter.removeTracks(playlistTracks,bannedTracks)
      Playlist.saveWithReplace({
        id: '7BpAuAyoNGmEu3OLC65aCN',
        name: 'heard, liked, them forgotten',
        tracks: playlistTracks,});
    }};

It was bug. Update your library code.

And more readable example

function updateHeardLikedandForgotten() {
  const PLAYLIST_ID = '7BpAuAyoNGmEu3OLC65aCN';
  let recentTracks = RecentTracks.get(10000);
  let bannedTracks = Source.getPlaylistTracks('', '4Ep4JuDSqaIvd2OzraWRSt');

  let tracks = Selector.isDayOfWeek('monday') ? findTracks() : reorderTracks();
  Playlist.saveWithReplace({
    id: PLAYLIST_ID,
    name: 'heard, liked, them forgotten',
    tracks: tracks,
  });

  function findTracks() {
    let savedTracks = Cache.read('SavedTracks');
    Filter.removeTracks(savedTracks, Combiner.push(recentTracks, bannedTracks));
    let startDate = new Date('2006-01-01');
    let endDate = Filter.getDateRel(30, 'endDay');
    Filter.rangeDateAbs(savedTracks, startDate, endDate);
    Selector.keepRandom(savedTracks, 200);
    Order.sort(savedTracks, 'features.acousticness', 'desc');
    return savedTracks;
  }

  function reorderTracks() {
    let playlistTracks = Source.getPlaylistTracks('', PLAYLIST_ID);
    Filter.removeTracks(playlistTracks, bannedTracks)
    if (Selector.isDayOfWeek('tuesday')) {
      Order.sort(playlistTracks, 'features.danceability', 'asc');
    } else if (Selector.isDayOfWeek('wednesday')) {
      Order.sort(playlistTracks, 'features.valence', 'desc');
    } else if (Selector.isDayOfWeek('thursday')) {
      Order.sort(playlistTracks, 'features.tempo', 'asc');
    } else if (Selector.isDayOfWeek('friday')) {
      Order.sort(playlistTracks, 'features.key', 'desc');
    } else if (Selector.isDayOfWeek('saturday')) {
      Order.sort(playlistTracks, 'artist.populatrity', 'desc');
    } else {
      Order.sort(playlistTracks, 'features.danceability', 'asc');
    }
    return playlistTracks;
  }
}

Thank you for the advice and the neater code!

Hi, me again - since yesterday I am now getting the following error, regardless of what function I'm running. I've checked and updated the library code but I'm a bit lost as to what is causing it

Probably, you used too many requests and Spotify blocked their. Because 31554 is unbelievable value when script starting.

Wait some time. And I recommend to optimise your algorithms.
