MVC嵌套对象验证问题 [英] MVC nested object validation problem
问题描述
假设我有一个具有ID数据邮件等的用户。
Lets say I have an object User with ID dat mail etc.
如下所示
public class User
{
[Display(Name = "UserID", ResourceType = typeof(Resource))]
public int UserID { get; set; }
[Display(Name = "UserName", ResourceType = typeof(Resource))]
[Required(ErrorMessageResourceName = "UserNameRequired", ErrorMessageResourceType = typeof(Resource))]
[RegularExpression(@"^[a-zA-Z]+[ a-zA-Z-_]*$", ErrorMessageResourceName = "UserNameIsNotValid", ErrorMessageResourceType = typeof(Resource))]
public string UserName { get; set; }
[Display(Name = "UserMail", ResourceType = typeof(Resource))]
[Required(ErrorMessageResourceName = "UserMailRequired", ErrorMessageResourceType = typeof(Resource))]
[EmailAddress(ErrorMessageResourceName = "UserMailIsNotValid", ErrorMessageResourceType = typeof(Resource))]
public string UserMail { get; set; }
[Display(Name = "UserDate", ResourceType = typeof(Resource))]
[Required(ErrorMessageResourceName = "UserDateRequired", ErrorMessageResourceType = typeof(Resource))]
[DataType(DataType.Date, ErrorMessageResourceName = "UserDateIsNotValid", ErrorMessageResourceType = typeof(Resource))]
[DisplayFormat(DataFormatString = "{0:dd-MM-yyyy hh:mm:ss}", ApplyFormatInEditMode = true)]
public DateTime UserDate { get; set; }
}我有一个用户DTO
类似于以下类似的属性用户
Like below similar properties as User
public class UserDto
{
[Display(Name = "UserID", ResourceType = typeof(Resource))]
public int UserID { get; set; }
[Display(Name = "UserName", ResourceType = typeof(Resource))]
[Required(ErrorMessageResourceName = "UserNameRequired", ErrorMessageResourceType = typeof(Resource))]
[RegularExpression(@"^[a-zA-Z]+[ a-zA-Z-_]*$", ErrorMessageResourceName = "UserNameIsNotValid", ErrorMessageResourceType = typeof(Resource))]
public string UserName { get; set; }
[Display(Name = "UserMail", ResourceType = typeof(Resource))]
[Required(ErrorMessageResourceName = "UserMailRequired", ErrorMessageResourceType = typeof(Resource))]
[EmailAddress(ErrorMessageResourceName = "UserMailIsNotValid", ErrorMessageResourceType = typeof(Resource))]
public string UserMail { get; set; }
[Display(Name = "UserDate", ResourceType = typeof(Resource))]
[Required(ErrorMessageResourceName = "UserDateRequired", ErrorMessageResourceType = typeof(Resource))]
[DataType(DataType.DateTime, ErrorMessageResourceName = "UserDateIsNotValid", ErrorMessageResourceType = typeof(Resource))]
[DisplayFormat(DataFormatString = "{0:dd-MM-yyyy hh:mm:ss}", ApplyFormatInEditMode = true)]
public DateTime UserDate { get; set; }
}我有一个 视图模型 如下...
I have a ViewModel like below...
public class UserVm
{
public UserVm()
{
this.UserDtos = new HashSet<UserDto>();
}
public UserDto UserDto { get; set; }
public IEnumerable<UserDto> UserDtos { get; set; }
}
我有一个如下所示的视图...
I have a View Like below...
@model aa.Models.UserVm
@{
ViewBag.Title = "Index";
}
<h2>Index</h2>
@if (Model != null)
{
using (Html.BeginForm("Index", "Home", FormMethod.Post))
{
@Html.Partial("~/Views/Home/UserDtoPartial.cshtml", Model.UserDto);
}
<hr />
<div style="background-color:#df8941">
<table class="table table-bordered table-hover">
<thead>
<tr>
<th>
@Html.LabelFor(m => m.UserDto.UserID)
</th>
<th>
@Html.LabelFor(m => m.UserDto.UserName)
</th>
<th>
@Html.LabelFor(m => m.UserDto.UserMail)
</th>
<th>
@*@Html.LabelFor(m => m.UserDto.UserDate)*@
</th>
<th>
@aa.Resources.Resource.Edit
</th>
<th>
@aa.Resources.Resource.Delete
</th>
</tr>
</thead>
<tbody>
@Html.Partial("UserDtoPartialDisplay", Model.UserDtos)
</tbody>
</table>
</div>
}我用于提交的部分
@model aa.Models.UserDto
<div style="background-color:sandybrown;padding:10px;">
<div class="form-group">
@Html.TextBoxFor(m => Model.UserName, new { @class = "form-control" })
@Html.ValidationMessageFor(m => Model.UserName)
</div>
<div class="form-group">
@Html.TextBoxFor(m => Model.UserMail, new { @class = "form-control" })
@Html.ValidationMessageFor(m => Model.UserMail)
</div>
@*<div class="form-group">
@Html.TextBoxFor(m => Model.UserDate,Model.UserDate.ToString("dd-MM-yyyy"), new { @class = "form-control" })
@Html.ValidationMessageFor(m => Model.UserDate)
</div>*@
<div class="form-group">
@Html.HiddenFor(m => Model.UserID)
<input type="submit" value="@aa.Resources.Resource.Submit" class="btn btn-info" />
</div>
</div>
我在视图中使用的用户列表的部分
the partial for the list of user I use on view to display
@model IEnumerable<aa.Models.UserDto>
@foreach (var item in Model)
{
<tr>
<td>
@item.UserID
</td>
<td>
@item.UserName
</td>
<td>
@item.UserMail
</td>
<td>
@*@item.UserDate*@
</td>
<td>
@Html.ActionLink(aa.Resources.Resource.Edit, "Index", "Home", new { id = item.UserID }, new { @class = "btn btn-info" })
</td>
<td>
@Html.ActionLink(aa.Resources.Resource.Delete, "DeleteUser", "Home", new { id = item.UserID }, new { @class = "btn btn-info" })
</td>
</tr>
}
The HttpPost Action which response the request
The HttpPost Action which response the request
is
Like below..
Like below..
[HttpPost]
public ActionResult Index(UserDto userDtox)
{
if (ModelState.IsValid)
{
User usr = ctx.Userlar.Find(userDtox.UserID);
Mapper.Map(userDtox, usr);
this.ctx.SaveChanges();
}
List<UserDto> usersDtos = Mapper.Map<List<UserDto>>(ctx.Userlar.ToList<User>());
UserVm usrVm = new UserVm
{
UserDto = userDtox,
UserDtos = usersDtos
};
return View(usrVm);
}the problem is it does not validate allays.

推荐答案
MVC is primarily used for Web applications, and you got some html code in there.

So I asume this is a ASP.Net web application. ASP.Net has it’s own Forum that is also used for everything web related:
