【问题描述】：
我试过了，但我认为我仍然需要修复我的控制器
我需要将数据从我的数据库中获取到数据表中
这是我的桌子和我的 js
<table id="myTable" class="display nowrap" style="width:100%">
<thead>
<tr>
<th>Status</th>
<th>Date and Time</th>
<th>Comments</th>
</tr>
</thead>
</table>
我的Js
<!--Import jQuery before export.js-->
<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.1.min.js"></script>
<!--Data Table-->
<script type="text/javascript" src=" https://cdn.datatables.net/1.10.13/js/jquery.dataTables.min.js"></script>
<script type="text/javascript" src=" https://cdn.datatables.net/buttons/1.2.4/js/dataTables.buttons.min.js"></script>
<!--Export table buttons-->

<script type="text/javascript">
$(document).ready(function () {
$.noConflict();
$('#myTable').DataTable({
"ajax": {
"url": "/Profile/Index/viewModel/EmployeeCollection/HistoryOfStatuses",
"type": "POST",
"datatype": "json"
},
"columns": [
{ "data": "CheckStatus", "name": "Status" },
{ "data": "CheckTime", "name": "Date and Time" }
],
"serverSide": "true",
"order": [0, "asc"],
dom: 'Bfrtip',
buttons: [
'copy', 'pdf', 'csv', 'print', 'excel'
]
});
});
我的控制器看起来像这样在这个数据表中我需要使用 HistoryOfStatuses
public IActionResult Index(int? Id)
{
using (var context = new RSAT.Api.Data.Proxy.ATT2018NOVUSContext())
{
var baseViewModel = base.GetLayoutViewModel();
var viewModel = new HomeViewModel()
{
User = baseViewModel.User,
RoleCollection = baseViewModel.RoleCollection,
TableCollection = baseViewModel.TableCollection,
//Olap = baseViewModel.Olap,
//Localization = baseViewModel.Localization,
EmployeeCollection = (from userinfo in context.Userinfo
where userinfo.Userid == Id
join department in context.Dept on userinfo.Deptid equals department.Deptid
select new Employee()
{
Id = userinfo.Userid,
Name = userinfo.Name,
Picture = userinfo.Picture,
Department = department.DeptName,
CardNumber = userinfo.CardNum,
Status = userinfo.UserFlag.ToString(),
ActualCheckinStatuse = (from checkinout in context.Checkinout
join status in context.Status on checkinout.CheckType equals status.Statusid
where checkinout.Userid == userinfo.Userid
orderby checkinout.CheckTime descending
select new Checkinout
{
CheckStatus = status.StatusText,
CheckTime = checkinout.CheckTime
}).FirstOrDefault(),
HistoryOfStatuses = (from checkinout in context.Checkinout
join status in context.Status on checkinout.CheckType equals status.Statusid
where checkinout.Userid == userinfo.Userid
orderby checkinout.CheckTime descending
select new Checkinout
{
CheckStatus = status.StatusText,
CheckTime = checkinout.CheckTime
}).ToList(),
TodayCheckedStatus = (from checkinout in context.Checkinout
join status in context.Status on checkinout.CheckType equals status.Statusid
where checkinout.Userid == userinfo.Userid
where checkinout.CheckTime.Date == DateTime.Today.Date
orderby checkinout.CheckTime descending
select new Checkinout
{
CheckStatus = status.StatusText,
CheckTime = checkinout.CheckTime
}).ToList()
}).ToList()
};
return View(viewModel);
}
这是我要使用的班级员工控制器。
public class Employee : BaseEntity
{
public Employee()
{
this.HistoryOfStatuses = new List<Checkinout>();
this.TodayCheckedStatus = new List<Checkinout>();
}
public string Name { get; set; }
public string Department { get; set; }
public string CardNumber { get; set; }
public string Status { get; set; }
public byte[] Picture { get; set; }
public Checkinout ActualCheckinStatuse { get; set; }
public List<Checkinout> HistoryOfStatuses { get; set; }
public List<Checkinout> TodayCheckedStatus { get; set; }
public int UserId { get; internal set; }
public string UName { get; set; }
public string UField { get; set; }
public string UDeg { get; set; }
//test
}
我需要使用数据表对pdf和exel中的数据进行排序和下载。
【问题讨论】：
-
嗨..你确定要返回 View(viewModel) 吗？ .. 不是 Jsonresult(viewModel) 吗？
-
您的 AJAX URL 在这里似乎是错误的。也不需要返回视图模型的所有实例，因为数据表中只有 2 列。
