If I am getting data from a json api (playlists.json), and the playlist object has a user_id data field, how can I get a specific playlist with user_id == 1?

I tried doing:

var playlists = Restangular.all('playlists');

playlists.getList().then(function(data) {
    for(var i = 0; i < data.length; i++) {
        var obj = data[i];
        if(obj.user_id == 1) {
            $scope.playlist = obj;                
        }
    }
});

But I would rather not retrieve all the playlists and loop through all of them as it seems very inefficient.

Thanks in advance!

Whether you do it, or let a framework do it, there will be a loop happening. Unless you can make a separate json file. –  Zack Argyle Dec 4 '13 at 23:00

If json api represents collection of playlist you can use:

Restangular.one('user_id', 1).then(function(data) {   
    $scope.playlist = data;  
});

But if you want preloaded list, I think there is no way but use loop

you could try something like this:

playlists.getList().then(function(data) {
        angular.forEach(data, function(value, key) {
            if(value.user_id == 1) {
                scope.playlist = value;
                return;
            }
        });

    });
