我创建了一个视图模型以及关联的控制器和视图，但是看起来我的头和代码都缺少了一部分。提交页面时，无论是否更改数据库，我都会得到以下信息。 “实体类型ReportReviewViewModel不是当前上下文模型的一部分。”
模型（并非所有字段）
public partial class RFDS
{
public System.Guid rfds_processing_id { get; set; }
public string location_name { get; set; }
public string address { get; set; }
}
public partial class Sub_Clients_Xref
{
public int id { get; set; }
public string sub_client { get; set; }
public string sub_client_attn { get; set; }
public string sub_client_address { get; set; }
}
public partial class Engineering_License_Xref
{
public int id { get; set; }
public string state_name { get; set; }
public string license_number { get; set; }
}
ViewModel
public class ReportReviewViewModel
{
public RFDS rfds { get; set; }
public Sub_Clients_Xref subclient { get; set; }
public Engineering_License_Xref engineer { get; set; }
public States_Xref state { get; set; }
}
控制器
public ActionResult Review(Guid? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
RFDS rfds_db = db.RFDS.Find(id);
if (rfds_db == null)
{
return HttpNotFound();
}
List<RFDS> rfds1 = db.RFDS.ToList();
List<Sub_Clients_Xref> subclients = db.Sub_Clients_Xref.ToList();
List<Engineering_License_Xref> engineers = db.Engineering_License_Xref.ToList();
List<States_Xref> states = db.States_Xref.ToList();
var viewModel = (from r in rfds1
join s in subclients on r.sub_client equals s.sub_client
join st in states on r.state equals st.state
join e in engineers on r.engineer_name equals e.engineer_name
where r.rfds_processing_id == id && r.sub_client == s.sub_client &&
(r.engineer_name == e.engineer_name && e.state_name == st.state_name)
select new ReportReviewViewModel
{
rfds = r,
subclient = s,
engineer = e
});
return View(viewModel);
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Review(ReportReviewViewModel viewModel)
{
if (ModelState.IsValid)
{
db.Entry(viewModel).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Review");
}
return View(viewModel);
}
UPDATED CONTROLLER
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Review(ReportReviewViewModel viewModel)
{
if (ModelState.IsValid)
{
db.Entry(viewModel.rfds).State = EntityState.Modified;
db.Entry(viewModel.engineer).State = EntityState.Modified;
db.Entry(viewModel.subclient).State = EntityState.Modified;
db.Entry(viewModel.state).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Review");
}
