沼澤龍對象排序不正確

Question

我有一個實時應用程序，此應用程序從管理站點向我提供公告。 不幸的是，我無法處理訂購問題，因為新信息必須位於列表的頂部。 我的應用程序使我位於列表的底部。 刷新后，它修復了列表，但我不想刷新所有新信息。 刷新之前：

• afas 2015-07-21 12:07:10
• 5分鍾2015-07-21 12:07:03
• 5分鍾2015-07-21 12:27:16

刷新后：

• 5分鍾2015-07-21 12:27:16
• afas 2015-07-21 12:07:10
• 5分鍾2015-07-21 12:07:03

controller.js：

var AnnounceControllers = angular.module('AnnounceControllers', []);

AnnounceControllers.controller('AnnounceListCtrl', ['$scope', '$dragon', function ($scope, $dragon) {
$scope.announceList = {};
$scope.announcements = [];
$scope.channel = 'announce';

$dragon.onReady(function() {
    $dragon.subscribe('announcements', $scope.channel, {announce_list__id: 1}).then(function(response) {
        $scope.dataMapper = new DataMapper(response.data);
    });

    $dragon.getSingle('announce-list', {id:1}).then(function(response) {
        $scope.announceList = response.data;
    });

    $dragon.getList('announcements', {list_id:1}).then(function(response) {
        $scope.announcements = response.data;
    });
});

$dragon.onChannelMessage(function(channels, message) {
    if (indexOf.call(channels, $scope.channel) > -1) {
        $scope.$apply(function() {
            $scope.dataMapper.mapData($scope.announcements, message);
        });
    }
});
}]);

routers.py：

from swampdragon import route_handler
from swampdragon.route_handler import ModelRouter
from post.models import AnnounceList, Announce
from post.serializers import AnnounceListSerializer, AnnounceSerializer


class AnnounceListRouter(ModelRouter):
    route_name = 'announce-list'
    serializer_class = AnnounceListSerializer
    model = AnnounceList

    def get_object(self, **kwargs):
        return self.model.objects.get(pk=kwargs['id'])

    def get_query_set(self, **kwargs):
        return self.model.objects.all()


class AnnounceRouter(ModelRouter):
    route_name = 'announcements'
    serializer_class = AnnounceSerializer
    model = Announce

    def get_object(self, **kwargs):
        return self.model.objects.get(pk=kwargs['id'])

    def get_query_set(self, **kwargs):
        return  self.model.objects.filter(announce_list__id=kwargs['list_id']).order_by("-pub_date")


route_handler.register(AnnounceListRouter)
route_handler.register(AnnounceRouter)

在HTML中：

<h3 ng-repeat="item in announcements | orderBy: '-date'">

我設法通過orderBy過濾器訂購
