jQuery的排序和MVC停止工作 [英] jQuery Sort and MVC Stopped Working

问题描述

我收到以下错误，当JQuery的排序叫我的排序动作：

I am getting the following error when JQuery Sort calls my sort action:

参数词典共包含参数法System.Web.Mvc.EmptyResult SortDonations（System.Collections.Generic.List 1 [System.Int32]）'中的无效条目DonationIDS'' Vol.Web.Areas.ActivityArea.Controllers.DonationController。该字典包含类型的值'System.Collections.Generic.List 1 [Vol.Models.Token]'，但参数需要的类型System.Collections.Generic.List`1值' [System.Int32]结果参数名：参数

The parameters dictionary contains an invalid entry for parameter 'DonationIDS' for method 'System.Web.Mvc.EmptyResult SortDonations(System.Collections.Generic.List1[System.Int32])' in 'Vol.Web.Areas.ActivityArea.Controllers.DonationController'. The dictionary contains a value of type 'System.Collections.Generic.List1[Vol.Models.Token]', but the parameter requires a value of type 'System.Collections.Generic.List`1[System.Int32]'.
Parameter name: parameters

jQuery的：

$("#dlist").sortable({
        handle: '.sorthandle',
        update: function () {
            var order = $('#dlist').sortable('toArray');
            $.ajax({
                url: '/activity/donation/sortdonations',

                data: { DonationIDS: order },
                type: 'POST',
                traditional: true
            });
        }
    });

邮政值：

Parametersapplication/x-www-form-urlencoded
DonationIDS 1
DonationIDS 8
Source
DonationIDS=1&DonationIDS=8

MVC动作：

 public EmptyResult SortDonations(List<int> DonationIDS)
        {


            int order = 0;
            foreach (int i in DonationIDS)
            {
                donationRepository.UpdateSortOrder(i, order);
                order++;
            }


            return new EmptyResult();
        }

这是完全工作，但现在看来引用另一个类，令牌。任何想法是怎么回事，或从哪里开始寻找？

It was working perfectly but now it seems to reference another class, Token. Any ideas what is going on or where to start looking?

推荐答案

只需添加以下在Global.asax的Application_Start方法

Just add the following to the global.asax Application_Start method

ModelMetadataProviders.Current = new DataAnnotationsModelMetadataProvider();
