[英]MVC Validation on Production Site Fails
在Localhost上,我的用户帐单地址验证在提交之前有效。 一旦我将项目推向生产。 验证不会启动,并且我收到以下错误“序列不包含任何元素 。它指向我的控制器”。model.Address = db.Addresses.Where(a => a.AddressId == model.AddressId).Single(); ”。
视图
@using (Html.BeginForm()) {
@Html.ValidationSummary(true)

控制者
[HttpPost]
public ActionResult Edit(UserProfile model)
{
model.Address = db.Addresses.FirstOrDefault(a => a.AddressId == model.AddressId);
// check to verify that the phone number length is correct
// (when using an input mask, this shouldn't be a problem)
if (model.Phone.Length != 14)
{
ModelState.AddModelError("", "please enter a valid phone number");
}
if (model.Mobile != null && model.Mobile.Length != 14)
{
ModelState.AddModelError("", "please enter a valid mobile number");
}
// checks to make sure the user is 18 years old
if (model.DateOfBirth.Date > DateTime.Now.AddHours(2).Date.AddYears(-18))
{
ModelState.AddModelError("", "you must be at least 18 years of age");
}
if (ModelState.IsValid)
{
db.Entry(model).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("MyAccount", "Account");
}
return View(model);
}
模型
namespace XYZ.Models.Domain
{public class UserProfileMetadata
{
[HiddenInput(DisplayValue = false)]
[Display(Name = "User Id")]
public int UserId { get; set; }
[Required(ErrorMessage = "please enter your first name")]
[Display(Name = "First name")]
public string FirstName { get; set; }
[Required(ErrorMessage = "please enter your last name")]
[Display(Name = "Last name")]
public string LastName { get; set; }
[Display(Name = "Date of Birth")]
[DisplayFormat(DataFormatString = "{0:d}", ApplyFormatInEditMode = true)]
public DateTime DateOfBirth { get; set; }
[Required(ErrorMessage = "please enter a phone number")]
public string Phone { get; set; }
//[Required(ErrorMessage = "please enter a mobile number")]
public string Mobile { get; set; }
[Required(ErrorMessage = "please select a gender")]
public string Gender { get; set; }
[Display(Name = "Address")]
public Nullable<int> AddressId { get; set; }
[Required(ErrorMessage = "please select an activation status")]
[Display(Name = "Is Active")]
public bool IsActive { get; set; }
}
我猜你在这里看到错误:
model.Address = db.Addresses.Where(a => a.AddressId == model.AddressId).Single();
尝试.SingleOrDefault()。
还要检查db.Addresses是否为空
if (model.Address != null && db.Addresses.Any())
编辑:试试这个
model.Address = db.Addresses.FirstOrDefault(a => a.AddressId == model.AddressId);
EDIT2:如果不是新地址,则仅分配具有现有地址的model.Address:
if (model.AddressId != null && db.Addresses.Any(a => a.AddressId == model.AddressId))
model.Address = db.Addresses.First(a => a.AddressId == model.AddressId);
