我正在尝试将更改保存到基本CRUD中。我在我的模型中编辑了3个列的视图(表格有7列)。
我尝试了在不同的帖子中引用的附加方法。任何想法都将不胜感激。
模型
public class AssetRequest
{
public int Id { get; set; }
[DataType(DataType.Date)]
[Display(Name = "Request date")]
public DateTime AssetRequestDate { get; set; }
[Display(Name = "Facility")]
public int FacilityId { get; set; }
[Required]
[Display(Name = "Asset requested")]
public int AssetId { get; set; }
[Display(Name ="Serial no.")]
public string AssetSN { get; set; }
[Required]
[Display(Name = "Request type")]
public int RequestTypeId { get; set; }
[Required]
[DataType(DataType.Date)]
[Display(Name = "Job date")]
public DateTime JobRequestDate { get; set; }
[Required]
[Display(Name = "Request status")]
public int RequestStatusId { get; set; }
[Display(Name = "Tracking no.")]
public string TrackingNo { get; set; }
[Display(Name = "Comments")]
public string Comments { get; set; }
[Display(Name = "Sending facility")]
public string SendingFacilityt { get; set; }
public virtual Asset Asset { get; set; }
public virtual Facility Facility { get; set; }
public virtual ApplicationUser User { get; set; }
public virtual RequestType RequestType { get; set; }
public virtual RequestStatus RequestStatus { get; set; }
}
}
控制器
public async Task<ActionResult> Edit([Bind(Include = "RequestStatusId, TrackingNo, Comments")] AssetRequest assetRequest)
{
if (ModelState.IsValid)
{
//db.AssetRequestTable.Attach(assetRequest);
db.Entry(assetRequest).State = EntityState.Modified;
await db.SaveChangesAsync();
return RedirectToAction("All");
}
}

您需要将Id属性(主键)包含在Include列表中,以便EF可以获取该项并进行更新。
public async Task<ActionResult> Edit([Bind(Include = "Id,RequestStatusId, TrackingNo,
Comments")] AssetRequest assetRequest)
{
// your code
}
看起来您正在使用实体模型作为参数来更新实体值。 A better approach to prevent over posting is to use a view model
