Question

我有两个表类别和产品。

Category:- CategoryId,CategoryName
Product:- ProductId, ProductName, Price, CategoryId(FK)

我想从单个视图添加数据。我将类别创建为局部视图并将其呈现为“创建页面”。

控制器是： -

public class ProductController : Controller
{
    private StoreDbEntities db = new StoreDbEntities();

    //
    // GET: /Product/

    public ActionResult Index()
    {
        var products = db.products.Include(p => p.Category);
        return View(products.ToList());
    }

    //
    // GET: /Product/Details/5

    public ActionResult Details(int id = 0)
    {
        product product = db.products.Find(id);
        if (product == null)
        {
            return HttpNotFound();
        }
        return View(product);
    }

    //
    // GET: /Product/Create

    public ActionResult Create()
    {
        ViewBag.CategoryId = new SelectList(db.Categories, "CategoryId", "CategoryName");
        return View();
    }
    public ActionResult CreateCategory()
    {
        return View();
    }

    [HttpPost]
    public ActionResult CreateCategory(Category category)
    {
        if(ModelState.IsValid)
        {
            db.Categories.Add(category);
            db.SaveChanges();
            return RedirectToAction("Create");
        }
        return View(category);
    }
    //
    // POST: /Product/Create

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create(product product)
    {
        if (ModelState.IsValid)
        {
            db.products.Add(product);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        ViewBag.CategoryId = new SelectList(db.Categories, "CategoryId", "CategoryName", product.CategoryId);
        return View(product);
    }

}

和创建视图是： -

    @model MvcApplication9.Models.Category

@Html.Partial("_Category",Model);

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

    <fieldset>
        <legend>Category</legend>

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

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

和_Categoy视图是： -

@model MvcApplication9.Models.Category

<script src="~/Scripts/jquery-1.8.2.min.js"></script>
<script src="~/Scripts/jquery.validate.min.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>

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

    <fieldset>
        <legend>Category</legend>

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

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

当我运行它时显示错误＆＃34;一个或多个实体的验证失败。请参阅＆＃39; EntityValidationErrors＆＃39;物业详情。＆＃34;。请帮我解决这个问题。在此先感谢。
