我希望有人可以提供帮助，因为我多次尝试这种情况并没有取得什么成功。我试图使用django书中的探戈来适应这种情况，并在网上做了许多其他例子，但没有运气。总之...
我目前正在设计一个小型假新闻＆＃39;有Django的网站，它有一个迷你游戏，向用户显示新闻文章（标题，描述，图片），他们必须投票是否是“事实”。或者＆＃39;小说＆＃39;然后告诉他们他们是否正确以及之前有多少人投票赞成该答案。
如果我将所有数据存储在如下的javascript变量中，我的工作完全正常：
var questions = [

我已经能够将所有文章添加到数据库中，但我不确定如何在需要时从数据库中提取数据，并在更多人玩游戏时更新事实和虚构投票的数量。通过在线阅读，我相信我需要使用AJAX来做到这一点，但我诚实地不知道从哪里开始，每次按下一个按钮时显示一篇新文章，更新投票数等。
希望有人能够至少指出我正确的方向，并且我会发布到目前为止我所拥有的所有代码，并认为可能与以下相关。

以下是ajax-request的示例。单击一个按钮时会触发它并向{％url“ajax_requests”％}发出POST请求。成功地将一些数据加载到div ... console.log（）仅用于检查返回的数据。
<script>
$("#button1").click(function () {
var itemid=1;
$.ajaxSetup({
data: {csrfmiddlewaretoken: '{{ csrf_token }}' },
});
$.ajax({
url: '{% url "ajax_requests" %}',
type: 'POST',
data: {
'item_id': itemid,
},
dataType: 'json',
success: function (data) {
if (data) {
console.log(data);
html = '<img src="/user_images/' + data[6].fields.requesting_user[2] + ' "class="img-responsive" alt="Kuva">';
$("#test").append(html);
}
}
});
});
</script>
因此，为了完成这项工作，您需要添加一个视图并从your_app / urls.py指向它。像这样：
url(r'^ajax_requests/', ajaxrequests_view, name='ajax_requests'),
并在views.py中查询数据，然后将其序列化为json并返回：
def ajaxrequests_view(request):
item_id = request.POST.get('item_id', None)
get_data = MyModel.objects.select_related('item_owner').filter(item_id=item_id)
ser_data = serializers.serialize("json", get_data)
return HttpResponse(ser_data, content_type="application/json")
