值"(字符串)"无效

Question

我目前有一个视图,其中包含两个文本框,用户可以在其中输入一些数据.一个文本框仅允许值1-10,另一个文本框为字符串.我不确定我做了什么代码更改,但接受字符串的第二个文本框不再"有效".例如,当我输入一个字符串并尝试提交表单时,我收到一条验证消息,指出"值"(字符串)"无效.以下是我的解决方案中的一些代码片段.

实体:

public class MovieReview
{
    public int Id { get; set; }

    [Range(1, 10)]
    [Required]
    public int Rating { get; set; }
    public string Review { get; set; }
    public int MovieId { get; set; }
}

控制器:

public class ReviewsController : Controller
{
    private MovieLoversDb _db = new MovieLoversDb();

    public ActionResult Index([Bind(Prefix = "id")]int movieId)
    {
        var movie = _db.Movies.Find(movieId);
        if (movie != null)
        {
            return View(movie);
        }
        return HttpNotFound();
    }

    [HttpGet]
    public ActionResult Create(int movieId)
    {
        return View();
    }

    [HttpPost]
    public ActionResult Create(MovieReview review)
    {
        if (ModelState.IsValid)
        {
            _db.MovieReviews.Add(review);
            _db.SaveChanges();
            return RedirectToAction("Index", new { id = review.MovieId });
        }
        return View(review);
    }

局部视图:

@model MovieLovers.Models.MovieReview

@{
    ViewBag.Title = "Review a Movie";
}

<h2>Review a Movie</h2>

@using (Html.BeginForm()) {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

<fieldset>
    <legend>New Review</legend>

    <div class="editor-label">
        @Html.LabelFor(model => model.Rating)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Rating)
        @Html.ValidationMessageFor(model => model.Rating)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.Review)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Review)
        @Html.ValidationMessageFor(model => model.Review)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.ReviewerName)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.ReviewerName)
        @Html.ValidationMessageFor(model => model.ReviewerName)
    </div>
    <p>
        <input type="submit" value="Create" />
    </p>
</fieldset>
}

现在的问题是,我做错了什么？为什么会产生验证错误？

Answer 1

我用Jasen的建议在原帖中的评论中找出了它.似乎"评论"可能已被使用了两次,虽然我找不到哪里.我将属性名称更改为"body",现在它可以正常工作.

感谢你的帮助!
