实时通知应用程序DateTimeField问题

Question

我用swampdragon写了一个通知应用。不幸的是，pub_date变量包含了我不希望它存在的微秒数。我如何将其格式化为'dd-MM-yyyy HH:mm:ss'或像在管理网站(a. .下午版)?我的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);
        });
    }
});
}]);

我app.js

:

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

在HTML中:

<h3 ng-repeat="item in announcements">
        <div class="alert alert-info" role="alert">
          {{ item.content }} {{item.pub_date| date:'dd-MM-yyyy HH:mm:ss'}}
          <br>
        </div>
      </h3>

models.py:

pub_date = models.DateTimeField(auto_now_add = True)

serializers.py:

class AnnounceSerializer(ModelSerializer):
class Meta:
    model = "post.Announce"
    publish_fields = ("content","pub_date")

Answer 1

你必须将DateTimeField转换为ISO 8061格式，这样AngularJS的日期过滤器才能工作:

pub_date = models.DateTimeField(auto_now_add = True).isoformat(' ')

查看更多信息

编辑:

进一步澄清后，问题是你得到的时间戳格式不正确，javascript无法将其识别为日期。

Answer 2

我使用了Daniel Cottone的一些信息，并做了这些:

class Announce(SelfPublishModel, models.Model):
serializer_class = AnnounceSerializer
announce_list = models.ForeignKey(AnnounceList)
content = models.CharField(max_length=100)
pub_date = models.DateTimeField(default=datetime.now)
date = models.TextField(null=True)
def __unicode__(self):
    return self.content

@receiver(pre_save,sender=Announce)
   def date_handler(sender,instance,*args,**kwargs):
       instance.date = instance.pub_date.isoformat()

没有参数的

isoformat对我有效。
