每当我提交表单时,传递给控制器的模型都是NULL。我花了很多年看这个。我想我在这里错过了一些基本的东西。模型在表单发布到控制器时始终为NULL
@model VisitorPortal.Models.ReinviteVisitorModel
@using (Html.BeginForm("CreateMeeting", "Home", FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
{
@Html.AntiForgeryToken()
<h3>Reinvitation Details</h3>
<div>The information entered below will be sent to the visitors email address @Model.Info.Email</div>
<hr />
@Html.ValidationSummary("", new { @class = "text-danger" })
<div class="form-group">
@Html.LabelFor(m => m.NewMeeting.Title, new { @class = "col-md-2 control-label" })
<div class="col-md-10">
@Html.TextBoxFor(m => m.NewMeeting.Title, new { @class = "form-control" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(m => m.NewMeeting.StartTime, new { @class = "col-md-2 control-label" })
<div class="col-md-10">
@Html.TextBoxFor(m => m.NewMeeting.StartTime, new { @class = "datetimepicker form-control" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(m => m.NewMeeting.EndTime, new { @class = "col-md-2 control-label" })
<div class="col-md-10">
@Html.TextBoxFor(m => m.NewMeeting.EndTime, new { @class = "datetimepicker form-control" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
@Html.HiddenFor(m => m.NewMeeting.SubjectId, new { @Value = Model.Info.SubjectId })
<input type="submit" class="btn btn-default" value="Send Invite" />
</div>
</div>
}
的型号是:
public class Meeting
{
[Key]
public int Id { get; set; }
public string SubjectId { get; set; }
[Required]
[Display(Name = "Reason for invitation")]
public string Title { get; set; }
[Required]
[Display(Name = "Start Time")]
[DataType(DataType.Time)]
public DateTime StartTime { get; set; }
[Required]
[Display(Name = "End Time")]
[DataType(DataType.Time)]
public DateTime EndTime { get; set; }
public string HostEmail { get; set; }
public string HostMobile { get; set; }
}
public class MeetingsDBContext: DbContext
{
public DbSet<Meeting> Meetings { get; set; }
}
public class ReinviteVisitorModel
{
public Visitor Info;
public Meeting NewMeeting;
public List<Meeting> Meetings;
}
控制器中的操作是:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult CreateMeeting(Meeting meeting)
{
return RedirectToAction("ReinviteVisitor2", "Home", new { visitorId = meeting.SubjectId });
}
我在模型领域如身份证,我很期待数据库来填充这点我是将在动作CreateMeeting()中写入。模型中的所有字段都必须在表单中使用吗?
你重定向到另一个动作'ReinviteVisitor2',PLZ添加其代码。顺便说一下,视图的文件名是什么? – akazemis
你传递的模型和你使用的模型是不同的,几乎为什么它返回null。 – denchu
