Reading data from firebase in angularfire - angularjs

Question

I have an app where I need to store artists and their details in database.Now I want to retrieve all the artists and render some of their details in front end.How to do that.
Secondly, if I get the artist rating in some input field by using ng-model, then how to store that value in a particular artist to update details.
The database structure is:
{
"artists": {
"Atif":{
"name":"atif",
"rating":8
},
"Himesh":{
"name":"himesh",
"rating":5
}
}
}
and this is angular.js
(function()
{
var app = angular.module("myapp", ["firebase"]);
app.controller("maincontroller", function($scope, $firebaseObject,$firebaseArray)
{
var ref = new Firebase("https://gigstart.firebaseio.com/");
var artists=ref.child("artists");
// download the data into a local object
$scope.data = $firebaseObject(ref);
// putting a console.log here won't work, see below
ref.on("value", function(snapshot)
{
console.log(snapshot.val());
}, function (errorObject)
{
console.log("The read failed: " + errorObject.code);
});
var artistsRef=new Firebase("https://gigstart.firebaseio.com//artists");
}); //end of controller
Now I want to render the name and rating of each artist in front end.Can I do something like
<div ng-repeat="artist in artists">
{{artist.name}}
{{artist.rating}}
</div>

Answer 1

You have a list of artists, which you want to ng-repeat over in your Angular view. You can accomplish that by:
app.controller("maincontroller", function($scope, $firebaseArray)
{
var ref = new Firebase("https://gigstart.firebaseio.com/");
var artists = ref.child("artists");
$scope.artists = new $firebaseArray(artists);
}
Please take a moment to go through the AngularFire quickstart before starting on your own project. This is covered in step 5.
