我有一个基本模型:
public class Events
{
public int Id { get; set; }
public string title { get; set; }
public string amount { get; set; }
public string Finance_Approval { get; set; }
}
我想将两个不同的控制器连接到这个单一视图,一个用于只能填写标题和金额字段的请求者。而Finance Manger的第二个控制器通过填写表中的Finance_Approval字段来批准请求。
我创建了两个控制器及其剃刀视图,如下所示:
请求者控制器:
public ActionResult Index()
{
return View();
}
public ActionResult Request(Events e)
{
_context.evt.Add(e);
_context.SaveChanges();
return Content("Added");
}
这是剃刀视图:
@using (Html.BeginForm("Request", "Requester"))
{
<div class="form-group">
@Html.LabelFor(a => a.title)
@Html.TextBoxFor(a => a.title, new { @class = "form-control" })
</div>
<div class="form-group">
@Html.LabelFor(a => a.amount)
@Html.TextBoxFor(a => a.amount, new { @class = "form-control" })
</div>
<button class="btn btn-primary">Request</button>
}
这是财务总监:
public ActionResult Index()
{
return View();
}
public ActionResult Approve(Events e)
{
_context.evt.Add(e);
_context.SaveChanges();
return Content("Approved!");
}
这是它的剃刀视图:
@using (Html.BeginForm("Approve", "Finance"))
{
<div class="form-group">
@Html.LabelFor(a => a.Finance_Approval)
@Html.TextBoxFor(a => a.Finance_Approval, new { @class = "form-control" })
</div>
<button class="btn btn-primary">Approve</button>
}
现在,基于两个控制器的剃刀视图设计,请求者可以插入两个预定义的字段,即标题和金额,因此财务管理器仅为Finance_Approval字段。
但问题是,每当财务经理批准来自其门户网站的请求时,可以将某些值称为“是”,然后将此值插入到一个全新的行中,该行与请求者填充的行没有任何关联。
我希望财务经理应该能够批准具有某些价值的行(由请求者填写),但我无法弄清楚逻辑。
@erShoaib以下是最终更新:
public ActionResult Index()
{
var all = _context.evt.ToList();
return View(all);
}
public ActionResult Details(int? Id)
{
if (Id == 0)
{
return HttpNotFound();
}
var evtt = _context.evt.Find(Id);
return View(evtt);
}
public ActionResult Approve(Events e)
{
if (e==null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
Events evt = _context.evt.Find(e.Id);
evt.Finance_Approval = e.Finance_Approval;
//_context.evt.Add(e);
_context.SaveChanges();
return Content("Approved!");
}
这是完整的索引:
@model IEnumerable<InsertFromdifferentControllers.Models.Events>
@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<table class="table table-bordered table-hover">
@foreach (var item in Model)
{
<tbody>
<tr>
<td>@item.Id</td>
<td>@item.title</td>
<td>@item.amount</td>
<td>@Html.ActionLink("Expand","Details","Finance", new { Id =
@item.Id},null)</td>
</tr>
</tbody>
}
</table>
这是详细信息的视图:
@model InsertFromdifferentControllers.Models.Events
<table class="table table-bordered table-hover table-responsive">
<tbody>
<tr>
<td>@Model.Id</td>
<td>@Model.title</td>
<td>@Model.amount</td>
@using (Html.BeginForm("Approve","Finance"))
{
<div class="form-group">
@Html.LabelFor(a=> a.Finance_Approval);
@Html.TextBoxFor(a=> a.Finance_Approval, new { @class="form-control"})
</div>
<button class="btn btn-primary">Save</button>
}
</tr>
</tbody>
你的Requester Controller
和它的View
是完美的意味着请求者成功地向db添加了新的记录。
例如:title = "Abc"
,amount="123"
和添加此记录后假设id
是10
现在在Finance Controller
你需要在Index
方法中获得以上记录
public ActionResult Index(int id=0) <= Pass "id=10"
{
if(id == 0)
{
return HttpNotFound();
//or code to handle request when id = 0
}
Events events = _context.evt.Find(id); <= The "Find" function can get record with id=10
return View(events); <= Pass found record to view.
}
在财务经理对Finance_Approval
以上记录的id
领域进行更改之后是10
例如:Finance_Approval = "Approved"
。然后,所有具有此新字段的记录字段都可以发布到Approve
中的Finance Controller
操作方法。
然后你需要更新以上记录
public ActionResult Approve(Events e) <= Now "e" contains id=10, title="Abc", amount="123" and Finance_Approval="Approved"
{
if(e == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
Events events = _context.evt.Find(e.id); <= Fetch record of id=10 from database.
events.Finance_Approval = e.Finance_Approval; <= Assign changes to found record with posted data from view.
_context.SaveChanges();
return Content("Approved!");
}
