的EntityType“我的资料”没有定义键。定义此的EntityType关键 [英] EntityType 'MyProfile' has no key defined. Define the key for this EntityType
问题描述
我不知道为什么我收到此错误信息。我在为它的SQL数据库中定义的主键。这里是我的code:
I am not sure why I am getting this error message. I have a primary key defined in my sql database for it. Here is my code:
[HttpPost]
public ActionResult Register(RegisterModel model)
{
if (ModelState.IsValid)
{
// Attempt to register the user
MembershipCreateStatus createStatus = MembershipService.CreateUser(model.UserName, model.Password, model.Email);
if (createStatus == MembershipCreateStatus.Success)
{
FormsService.SignIn(model.UserName, false /* createPersistentCookie */);
MembershipUser myObject = Membership.GetUser();
Guid UserID = (Guid)myObject.ProviderUserKey;
MyProfile profile = new MyProfile();
profile.Address = model.Address;
profile.City = model.City;
profile.Zip = model.Zip;
profile.State = model.State;
profile.UserId = UserID;
db.Profiles.Add(profile);
return RedirectToAction("Index", "Home");
}
else
{
ModelState.AddModelError("", AccountValidation.ErrorCodeToString(createStatus));
}
}
// If we got this far, something failed, redisplay form
ViewBag.PasswordLength = MembershipService.MinPasswordLength;
return View(model);
}
这是我的我的资料类别:
And this is my MyProfile Class:
namespace MatchGaming.Models
{
[Bind(Exclude = "ProfileId")]
public class MyProfile
{
[ScaffoldColumn(false)]
public int ProfileId { get; set; }
public Guid UserId { get; set; }
[DisplayName("Address")]
public string Address { get; set; }
[DisplayName("City")]
public string City { get; set; }
[DisplayName("Zip")]
public string Zip { get; set; }
[DisplayName("State")]
public string State { get; set; }
}
}
我不知道为什么我收到此错误:的EntityType我的资料没有定义键。定义此的EntityType关键 code>当它试图添加到数据库
db.Profiles.Add(配置文件);
。
I am not sure why I am getting this error: EntityType 'MyProfile' has no key defined. Define the key for this EntityType.
when it tries to add to the database db.Profiles.Add(profile);

推荐答案
哪些领域是你的钥匙?无论它是 - 配置文件ID或用户ID - 要么将名称更改为MyProfileId或ID或者把[关键]属性就可以了。
Which field is your key? Whichever it is - ProfileId or UserId - either change the name to MyProfileId or Id or else put a [Key] attribute on it.
