创建视图发布空对象 [英] Create view is posting null objects

问题描述

应该是一个很容易回答的问题。
我想创建一个视图对象。包含该对象的类由User类和密码。
当我点击提交按钮，控制器拿起密码和用户空值。
见Container类，控制器和视图下方;

Should be an easy question to answer. I am trying to create an object in a view. The class that contains the object consists of a User class and a password. When I click on the submit button, the Controller picks up null values for Password and User. See below the Container class, the Controller and the View;

public class UserExtended
{
    public UserITOC User { get; set; }
    public string Password { get; set; }
}

    [Authorize]
    public ActionResult Create()
    {
        return View(new UserExtended());
    }

    //
    // POST: /Dinners/Create

    [Authorize(Roles = "Administrator")]
    [HttpPost]
    public ActionResult Create(UserExtended user)
    {
        if (ModelState.IsValid)
        {
            // Create user in the User datatable
            SqlUsersRepository sqlRepository = new SqlUsersRepository();
            ITOCEntities db = new ITOCEntities();
            db.UserITOCs.AddObject(user.User);

            // Create user as an authenticated user within the Reader role.
            int i = user.User.EmailAddress.IndexOf('@') - 1;
            string userName = user.User.EmailAddress.Substring(0, i);
            string email = user.User.EmailAddress;
            Membership.CreateUser(userName, user.Password, email);
            Roles.AddUserToRole(userName, "Reader");                // Automatically assigned as a Reader
        }
        return View(new UserExtended());
    }

推荐答案

非常简单的解决办法：

从

public ActionResult Create(UserExtended user)

到

public ActionResult Create(UserExtended UserExtended)

这样的ModelBinder的将知道如何从请求重组的对象。

That way the ModelBinder will know how to reassemble the object from Request.

希望这有助于！
