Question

我正在使用Django和Datatables，我正在为ListView做类似批量删除功能。

单击“删除”按钮时，会显示POST 500 (Internal Server Error)。但是当我刷新页面时，它会被成功删除。

'action': function() {
    // count check used for checking selected items.
    var count = table.rows({
        selected: true
    }).count();

    if (count > 0) {
        swal({
            title: "Are you sure you want to delete these items?",
            text: "There is NO undo!",
            type: "warning",
            showCancelButton: true,
            // confirmButtonColor: "#DD6B55",
            confirmButtonText: "Yes",
            cancelButtonText: "No",
            closeOnConfirm: true,
        }, function(isConfirm) {
            if (isConfirm) {
                var data = table.rows({
                    selected: true
                }).data();

                var list = [];

                for (var i = 0; i < data.length; i++) {
                    // alert(data[i][2]);
                    list.push(data[i][2]);
                }

                var sData = list.join();

                // alert(sData)
                document.getElementById('delete_items_list').value = sData;

                $.ajaxSetup({
                    beforeSend: function(xhr, settings) {
                        if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
                            xhr.setRequestHeader("X-CSRFToken", csrftoken);
                        }
                    }
                });
                $.ajax({
                    type: 'POST',
                    url: window.location.href,
                    data: {
                        'ids': sData
                    },
                    success: function() {
                        // Update page
                        window.location.reload();
                        swal("Deleted!", "The selected item/s were successfully deleted.", "success");
                    },
                    error: function() {
                        // Display message or something else
                        // swal("Error deleting!", "Please try again.", "error");
                    }
                });
            } else {
                return false;
            }
        });
    } else {
        swal("Error!", "You didn't select any items.", "error");
        return false;
    }
},

这是我在part（基于类的通用ListView）中的views.py：

class PartListView(LoginRequiredMixin, ListView):

    model = Part

    def post(self, request, *args, **kwargs):
        ids = self.request.POST.get('ids')
        ids = ids.split(",")
        # try:
            # Check ids are valid numbers
            # ids = map(int, ids)
        # except ValueError as e:
        #     return JsonResponse(status=400)
        # delete items
        self.model.objects.filter(id__in=ids).delete()
        return reverse('part')
        # return JsonResponse({"status": "ok"}, status=204)



    def get_context_data(self, **kwargs):
        context = super(PartListView, self).get_context_data(**kwargs)
        context['now'] = timezone.now()
        context['activate'] = 'part'
        return context

我还希望在页面重新加载后显示swal("Deleted!", "The selected item/s were successfully deleted.", "success"); sweetalert ，但它不起作用。这可能是因为500内部服务器错误而无法显示的原因。

我该如何解决这个问题？提前谢谢！

这就是用户界面的样子。

使用ajax post方法在发布帖子时发送csrf令牌，如下所示。您可以在ajax设置方法中设置csrf令牌，如下所示。

在发布请求时使用csrf令牌，这将阻止500服务器错误

// CSRF code
    function getCookie(name) {
        var cookieValue = null;
        var i = 0;
        if (document.cookie && document.cookie !== '') {
            var cookies = document.cookie.split(';');
            for (i; i < cookies.length; i++) {
                var cookie = jQuery.trim(cookies[i]);
                // Does this cookie string begin with the name we want?
                if (cookie.substring(0, name.length + 1) === (name + '=')) {
                    cookieValue = decodeURIComponent(cookie.substring(name.length + 1));

    // Use csrf token while doing post request, this will prevent 500 Server Error
    $.ajaxSetup({

    });

Answer 2

reverse函数以字符串格式返回一个您从post方法返回的url。它应该是一个响应对象。中间件尝试使用X-Frame-Options从响应对象获取get，但您的响应类型为str。

因此返回响应对象而不是字符串。

Answer 3

你得到内部错误，因为你应该返回Response实例（HttpResponse，HttpRedirectResponse，JsonResponse等）而不是字符串！

简单解决方案返回JsonResponse并删除reverse。

稍微难点，但我认为更好的解决方案，覆盖get_template_names方法

def get_template_names(self):
    if self.request.is_ajax():
        return ['app/_items_table.html', ]
    return ['app/items_list.html', ]

将_items_table加入items_list。并像这样更改post响应：

return super(PartListView, self).get(request, *args, **kwargs)

现在，在AJAX响应中，您应该替换页面上的完整表格，它可以帮助您摆脱页面重新加载。

Ajax 500 Internal Server但在刷新后和Django模型中被删除
