在ASP.NET MVC中提交表单后创建新的应用程序用户



我已经浏览了好几次代码，仍然不知道我可能做错了什么。在我的ASP.NET MVC应用程序中，我希望能够在通过视图模型提交表单后创建新用户。通过视图模型提交的部分信息将用于填充ApplicationUser模型。

这是我的视图模型

[Column(TypeName = "decimal(18,2)")]
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[Display(Name = "LoanAmount", ResourceType = typeof(Resources))]
public decimal LoanAmount { get; set; }
[Display(Name = "LoanPurpose", ResourceType = typeof(Resources))]
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
public LoanPurpose LoanPurpose { get; set; }
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[Display(Name = "FirstName", ResourceType = typeof(Resources))]
public string FirstName { get; set; }
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[Display(Name = "LastName", ResourceType = typeof(Resources))]
public string LastName { get; set; }
[Display(Name = "DateOfBirth", ResourceType = typeof(Resources))]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
public DateTime? DateOfBirth { get; set; }
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[Display(Name = "StreetAddress", ResourceType = typeof(Resources))]
public string Street { get; set; }
[MaxLength(15)]
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[Display(Name = "City", ResourceType = typeof(Resources))]
public string City { get; set; }
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[Display(Name = "State", ResourceType = typeof(Resources))]
public string State { get; set; }
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[Display(Name = "ZIP", ResourceType = typeof(Resources))]
public string ZipCode { get; set; }
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[Display(Name = "Country", ResourceType = typeof(Resources))]
public string Country { get; set; }
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[Display(Name = "Phone", ResourceType = typeof(Resources))]
public string Phone { get; set; }
[Column(TypeName = "decimal(18,2)")]
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[Display(Name = "MonthlyHousingPayment", ResourceType = typeof(Resources))]
public decimal MonthlyHousingPayment { get; set; }
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[Display(Name = "EmploymentStatus", ResourceType = typeof(Resources))]
public EmploymentStatus EmploymentStatus { get; set; }
[Column(TypeName = "decimal(18,2)")]
[Display(Name = "IndividualYearlyIncome", ResourceType = typeof(Resources))]
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
public decimal IndividualYearlyIncome { get; set; }
[Column(TypeName = "decimal(18,2)")]
[Display(Name = "AdditionalYearlyIncome", ResourceType = typeof(Resources))]
public decimal? AdditionalYearlyIncome { get; set; }
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[EmailAddress(ErrorMessageResourceType = typeof(Resources), ErrorMessageResourceName = "EmailInvalid")]
[Display(Name = "Email", ResourceType = typeof(Resources))]
public string Email { get; set; }
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[DataType(DataType.Password)]
[StringLength(100, ErrorMessageResourceType = typeof(Resources), ErrorMessageResourceName = "StringLength", MinimumLength = 4)]
[Display(Name = "Password", ResourceType = typeof(Resources))]
public string Password { get; set; }
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
[StringLength(20, ErrorMessageResourceType = typeof(Resources), ErrorMessageResourceName = "StringLength", MinimumLength = 4)]
[Display(Name = "Username", ResourceType = typeof(Resources))]
public string UserName { get; set; }
[Required(ErrorMessageResourceType = typeof(ValidationResources), ErrorMessageResourceName = "PropertyValueRequired")]
public bool AcceptCreditReportTerms { get; set; }
public Guid ApplicationUserId { get; set; }
public ApplicationUser ApplicationUser { get; set; }

这是我的控制器(CheckRateController(

// POST: CheckRate/Index
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Index(CheckYourRateViewModel model)
{
if (ModelState.IsValid)
{
var user = new ApplicationUser
{
FirstName = model.FirstName,
LastName = model.LastName,
UserName = model.UserName,
PhoneNumber = model.Phone,
DateOfBirth = model.DateOfBirth,
State = model.State,
Street = model.Street,
City = model.City,
Country = model.Country
};
var result = await _userManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
// Add registered users to Customer role
await _userManager.AddToRoleAsync(user.Id, "Customer");
}
var loanApplication = new Loan
{
LoanPurpose = model.LoanPurpose,
LoanAmount = model.LoanAmount,
EmploymentStatus = model.EmploymentStatus,
MonthlyHousingPayment = model.MonthlyHousingPayment,
IndividualYearlyIncome = model.IndividualYearlyIncome,
AdditionalYearlyIncome = model.AdditionalYearlyIncome,
ApplicationUserId = Guid.Parse(user.Id)
};
db.Loans.Add(loanApplication);
db.SaveChanges();
return RedirectToAction("Index", "Home");
}
return View(model);
}

这就是我的视图如何开始(Index.cshtml(

尝试更新BeginForm，使其看起来像这样。。。

Html.BeginForm("Index", "Home", FormMethod.Post)

我注意到，您正在使用带有if条件的">ModelState.IsValid"属性和if条件中的所有代码检查控制器方法中的模型状态是否有效。

通过在该位置添加断点进行检查，以检查您提交的表单模型此时是否有效。如果false，则不会根据您的逻辑保存您的数据。

另一件事是，在使用">ModelState.IsValid"时，要确保您没有为特定字段发布无效数据，就像您在视图模型中为十进制字段添加了验证一样，并且在表单中，您为该特定字段使用了"TextBoxFor"标记帮助程序，该标记帮助程序接受任何字符，对其他数据类型也是如此，因此请确保将正确的数据发布到控制器，否则">ModelState.IsValid"将为false。
