Angular - Can't make ng-repeat orderBy work

The orderBy only works with Arrays -- See http://docs.angularjs.org/api/ng.filter:orderBy

Also a great filter to use for Objects instead of Arrays @ Angularjs OrderBy on ng-repeat doesn't work

As mentioned, only arrays are allowed. But to make it simple for you, you could dynamically convert the object into an array via a piping function as seen herehttps://gist.github.com/brev/3949705

Just declare the filter, and add it to ng-repeat :)

<div ng-app="myApp"><script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script><div ng-controller="Main">  <div ng-repeat="release in releases | object2Array | orderBy:'environment_id'">{{release.environment_id}}</div></div><script>var app = angular.module('myApp', []).filter('object2Array', function() {    return function(input) {      var out = [];       for(i in input){        out.push(input[i]);      }      return out;    }  }).controller('Main',function ($scope) {        $scope.releases = {"tvl-c-wbap001 + tvl-webapp":{"timestamp":" 05:05:53 PM ","environment_id":"CERT5","release_header":"Projects/Dev","date":"19 Oct","release":"12.11.91-1"},"tvl-c-wbap401 + tvl-webapp":{"timestamp":" 10:07:25 AM ","environment_id":"CERT4","release_header":"Future Release","date":"15 Oct","release":"485-1"},"tvl-c-wbap301 + tvl-webapp":{"timestamp":" 07:59:48 AM ","environment_id":"CERT3","release_header":"Next Release","date":"15 Oct","release":"485-1"},"tvl-c-wbap201 + tvl-webapp":{"timestamp":" 03:34:07 AM ","environment_id":"CERT2","release_header":"Next Changes","date":"15 Oct","release":"13.12.3-1"},"tvl-c-wbap101 + tvl-webapp":{"timestamp":" 12:44:23 AM ","environment_id":"CERT1","release_header":"Production Mirror","date":"15 Oct","release":"13.11.309-1"},"tvl-s-wbap002 + tvl-webapp":{"timestamp":" 12:43:23 AM ","environment_id":"Stage2","date":"15 Oct","release":"13.11.310-1"},"tvl-s-wbap001 + tvl-webapp":{"timestamp":" 11:07:38 AM ","environment_id":"Stage1","release_header":"Production Mirror","date":"11 Oct","release":"13.11.310-1"},"tvl-p-wbap001 + tvl-webapp":{"timestamp":" 11:39:25 PM ","environment_id":"Production","release_header":"Pilots","date":"14 Oct","release":"13.11.310-1"},"tvl-p-wbap100 + tvl-webapp":{"timestamp":" 03:27:53 AM ","environment_id":"Production","release_header":"Non Pilots","date":"11 Oct","release":"13.11.309-1"}}    });</script>

the built-in orderBy filter will no longer work when iterating an object. It’s ignored due to the way that object fields are stored. You need create a custom filter

yourApp.filter('orderObjectBy', function() {  return function(items, field, reverse) {    var filtered = [];    angular.forEach(items, function(item) {      filtered.push(item);    });    filtered.sort(function (a, b) {      return (a[field] > b[field] ? 1 : -1);    });    if(reverse) filtered.reverse();    return filtered;  };});<ul><li ng-repeat="item in items | orderObjectBy:'color':true">{{ item.color }}</li></ul>
