Retrieve a specific JSON object from an array of JSON objects by applying a condition with Restangular

How can I efficiently retrieve a specific playlist with user_id == 1 from a json api (playlists.json) without having to loop through all playlists?

This is what I have tried so far:

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;                
        }
    }
});

I believe there might be a more efficient way to achieve this without retrieving and looping through all the playlists. Any suggestions would be greatly appreciated!

Answer №1

In the scenario where a json api represents a collection of playlist, you can utilize the following code snippet:

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

However, if you require a preloaded list, it seems that using a loop is the only feasible option.

Answer №2

One potential solution could look like the following:

playlists.getPlaylist().then(function(response) {
        angular.forEach(response, function(item) {
            if(item.user_id === 1) {
                scope.selectedPlaylist = item;
                return;
            }
        });

    });
