目前正在显示新通知的标题上的通知计数,它们有 is_read = False,我想更新 is_read = True 并删除通知计数,这就是我正在做的
上下文处理器
def notification(request):
"""Provide the count of unread notifications for an authenticated user."""
if request.user.is_authenticated():
notifications = Notification.objects.filter(user=request.user, is_read=False).\
order_by('-created')[:5]
return {'notification_count': len(notifications),
'notifications': notifications}
else:
return {}
html模板和ajax调用
{% if notification_count >= 1 %}
<a id="notification_menu" data-toggle="dropdown" class="dropdown-toggle" href="#">
<i class="ace-icon fa fa-bell icon-animated-bell"></i>
<span class="badge badge-important">{{ payzaat_notification_count }}</span>
</a>
{% endif %}
<script type="text/javascript">
(function($){
$('#notification_menu').on("click",function(){
console.log('clicked');
$.ajax({
type: "GET",
url: "{% url 'parent:update_notification' %}",
dataType: 'json',
success: function(response){
return true;
},error:function(response){
return false;
}
});
});
})(jQuery);
</script>
更新视图
类更新通知(FormView):
@method_decorator(parent_required)
def dispatch(self, request, *args, **kwargs):
return super(UpdateNotification, self).dispatch(request, *args, **kwargs)
def get(self, request, *args, **kwargs):
for record in Notification.objects.filter(user=self.request.user, is_read=False):
record.is_read = True
record.save()
return HttpResponse("OKAY")
我的模型已更新,但模板仍显示计数,直到我刷新页面
