MVC3的好奇問題，EF Code First。MVC3爲什麼我發佈的模型爲NULL？
我傳遞了一個模型，將兩個模型包裝到視圖中。
public class UserInfoModel
{
[Key]
[Required]
public int Id { get; set; }
/// <summary>
/// <para>Corresponds to ProviderUserKey in ASP Membership</para>
/// <para>Used in Membership.GetUser(ProviderUserKey) to retrieve email and username.</para>
/// </summary>
public Guid MembershipId { get; set; }
[Required]
[DataType(DataType.Text)]
[Display(Name = "First name")]
public string FirstName { get; set; }
[Required]
[DataType(DataType.Text)]
[Display(Name = "Last name")]
public string LastName { get; set; }
[Required]
[DataType(DataType.Text)]
[Display(Name = "Address 1")]
public string Address1 { get; set; }
[DataType(DataType.Text)]
[Display(Name = "Address 2")]
public string Address2 { get; set; }
[Required]
[DataType(DataType.Text)]
[Display(Name = "State")]
public string State { get; set; }
[Required]
[DataType(DataType.Text)]
[Display(Name = "Country")]
public string Country { get; set; }
[Required]
[DataType(DataType.Text)]
[Display(Name = "Zip code")]
public string ZipCode { get; set; }
[Required]
[DataType(DataType.PhoneNumber)]
[Display(Name = "Phone number")]
public string PhoneNumber { get; set; }
[Required]
[DataType(DataType.Date)]
[Display(Name = "Sign up date")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = @"{0:MM/dd\/yyyy}")]
public DateTime SignUpDate { get; set; }
[Required]
[DataType(DataType.Date)]
[Display(Name = "Birthday")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = @"{0:MM\/dd\/yyyy}")]
public DateTime BirthDate { get; set; }
[DataType(DataType.Date)]
[Display(Name = "Enrollment date")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = @"{0:MM\/dd\/yyyy}")]
public DateTime EnrollmentDate { get; set; }
[DataType(DataType.ImageUrl)]
[Display(Name = "Avatar")]
public string AvatarImage { get; set; }
[Display(Name = "Rank")]
public int RankId { get; set; }
[ForeignKey("RankId")]
public UserRankModel Rank { get; set; }
[Display(Name = "IsActive")]
public bool IsActive { get; set; }
}
public class RegisterModel
{
[Required]
[Display(Name = "User name")]
public string UserName { get; set; }
[Required]
[DataType(DataType.EmailAddress)]
[Display(Name = "Email")]
public string Email { get; set; }
[Required]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
[DataType(DataType.Password)]
[Display(Name = "Confirm password")]
[Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
public string ConfirmPassword { get; set; }
}
public class UserInfoAndRegisterModel
{
public UserInfoModel UserInfoModel { get; set; }
public RegisterModel RegisterModel { get; set; }
}

我的控制器類需要被張貼的模型，並做一些數據庫的更新。
其中一個包裹機型爲空：
[Authorize]
[HttpPost]
public ActionResult Edit(UserInfoAndRegisterModel model)
{
//WHY IS model.RegisterModel == null ??//
if (ModelState.IsValid)
{
try
{
dbContext.Entry(model.UserInfoModel).State = System.Data.EntityState.Modified;
dbContext.SaveChanges();
return RedirectToAction("Index", "Home");
}
catch (Exception ex)
{
throw new InvalidOperationException("Failed to update UserInfoModel", ex.InnerException);
}
}
GenerateRanksList();
return View(model);
}
我做同樣的事情在帳戶創建和我沒有收到一個空值RegisterModel幾乎相同的視圖代碼。
目前這是一個非問題，因爲我目前只更新UserInfoModel，但將來我可能想要允許用戶更改其電子郵件地址或用戶名。
任何想法？
你是100％正確。刪除'禁用'使模型非空。發佈代碼後，我認爲我會得到一個填充null屬性的非空模型。 –
