我很难让MVC绑定到我创建的模型。过去我已经成功完成了好几次。因此，我只是不确定为什么它不在这个项目中工作。C＃模型绑定到自定义类不工作
例如，我有以下观点：
@model StoryWall.ViewModels.ViewPostViewModel
@{
ViewBag.Title = "View Post";
}
<article class="story">
<header>
<h1>@Model.story.Title</h1>
<spann class="text-muted">@Model.story.Store.StoreName</span>
<h2>Posted by @Model.story.PosterName</h2>
</header>
if(@Model.story.StoryImage != null) {
<div class="storyImageWrapper">
<img src="~/img/@Model.story.StoryImage" />
</div>
<p>@Model.story.StoryBody</p>
}
</article>
<div class="commentsSection">
<h2>Comments</h2>
<h3>Add a Comment</h3>
<form method="post" class="form-horizontal" name="CommentForm" action="/View/AddComment">
@Html.AntiForgeryToken()
<input type="hidden" name="newComment.StoryID" value="@Model.story.StoryID" />
<div class="form-group"><label class="control-label col-sm-2">Name </label><div class="col-sm-10">@Html.TextBoxFor(@m => m.newComment.CommenterName, new { @class = "form-control", @required = true, @ng_model = "CommenterName"}) <span class="text-warning" ng-show="CommentForm.newComment.CommenterName.$dirty && CommentForm.newComment.CommenterName.$invalid"> Required </span> <span class="text-warning"> @Html.ValidationMessageFor(@m => m.newComment.CommenterName) </span></div> </div>
<div class="form-group"><label class="control-label col-sm-2">Email </label><div class="col-sm-10">@Html.TextBoxFor(@m => m.newComment.CommenterEmail, new { @class = "form-control", @required = true, @ng_model = "CommenterEmail" }) <span class="text-warning" ng-show="CommentForm.newComment.CommenterEmail.$dirty && CommentForm.newComment.CommenterEmail.$invalid"> Required </span> <span class="text-warning"> @Html.ValidationMessageFor(@m => m.newComment.CommenterEmail) </span></div> </div>
<div class="form-group"><label class="control-label col-sm-2">Message </label><div class="col-sm-10">@Html.TextAreaFor(@m => m.newComment.CommentBody, new { @class = "form-control", @required = true, @ng_model = "CommentBody" }) <span class="text-warning" ng-show="CommentForm.newComment.CommentBody.$dirty && CommentForm.newComment.CommentBody.$invalid"> Required </span> <span class="text-warning"> @Html.ValidationMessageFor(@m => m.newComment.CommentBody) </span></div> </div>
<button type="submit" ng-disabled="CommentForm.$invalid">Submit</button>
</form>
<h3>Current Comments</h3>
@foreach(var comment in @Model.story.Comments) {
<blockquote>@comment.CommentBody</blockquote>
<span>Poster: @comment.CommenterName on @comment.DatePosted.ToString("MM-dd-yyyy")</span>
}
</div>
即使我特别使用Html.TextBoxFor（）对我的输入框，绑定仍无法按预期工作。
这是我的控制器。第二个Action方法中的“注释”没有正确绑定;其属性为空。
public class ViewController : Controller
{
StoryModel dbContext = new StoryModel();
public ActionResult ViewPost(Int32 postID)
{
ViewPostViewModel vm = new ViewPostViewModel();
vm.story = dbContext.Stories.FirstOrDefault(s => s.StoryID == postID);
return View(vm);
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult AddComment(Comment comment)
{
if (ModelState.IsValid)
{
dbContext.Comments.Add(comment);
dbContext.SaveChanges();
return RedirectToAction("ViewPost", new { storyID = comment.StoryID});
}
else
{
ViewPostViewModel vm = new ViewPostViewModel();
vm.story = dbContext.Stories.FirstOrDefault(s => s.StoryID == comment.StoryID);
vm.newComment = comment;
return View("ViewPost", vm);
}
}
}
我知道这是不是第一次了类似的问题已经被问过，但我无法找到解决我的问题的解决方案。另外，如前所述，这是我过去成功所做的事情。
对我而言，这个场景中唯一的“新”元素是Angular.js。这是我第一次使用该框架。莫名其妙地干涉绑定？
如果有帮助，注释型号：
public partial class Comment
{
public int CommentID { get; set; }
public int? StoryID { get; set; }
public int UserID { get; set; }
[Required]
[StringLength(75)]
public string CommenterName { get; set; }
[Required]
[StringLength(75)]
public string CommenterEmail { get; set; }
[Required]
public DateTime DatePosted { get; set; }
[Required]
public string CommentBody { get; set; }
public virtual Story Story { get; set; }
public virtual User User { get; set; }
}
和ViewPostViewModel
public class ViewPostViewModel
{
public Story story { get; set; }
public Comment newComment { get; set; }
}
}多大的帮助
感谢。
