MVC 5 UserManager:实体类型ApplicationUser不是当前上下文模型的一部分 [英] MVC 5 UserManager: The entity type ApplicationUser is not part of the model for the current context
问题描述
我正在尝试(但未能)将MVC UserManager
实施到我的网站.我以为我的案子微不足道.我有一个User
类(实体框架-数据库优先),其中包含所有用户的信息.并非User
中的每个用户都可以访问该网站.因此,在我的ApplicationUser中,有一个指向此类的链接.在代码中,它看起来像这样:
I'm trying (but failing) to implement the MVC UserManager
to my website. I thought my case is fairly trivial. I have a User
class (Entity Framework - Database first) which contains all the user's info. Not every user from the User
has access to the website. So in my ApplicationUser there is a link to this class. In code it looks like this:
public partial class User
{
public int Id { get; set; }
public string Firstname { get; set; }
public string Lastname { get; set; }
public string Email { get; set; }
}
public class ApplicationUser : IdentityUser
{
public virtual Entities.User UserInfo { get; set; }
public ApplicationUser()
{
UserInfo = new Entities.User();
}
}
在控制器中调用CreateUserAsync
方法时,一切都会出错.您可以在下面找到我的控制器代码.
When invoking the CreateUserAsync
-method in the controller, it all goes wrong. Below you can find my controller code.
public class AccountController : BaseController
{
public UserManager<ApplicationUser> UserManager { get; private set; }
public async Task<ActionResult> Register(RegisterViewModel model)
{
if (ModelState.IsValid)
{
var dbUser = new User
{
Firstname = model.FirstName,
Lastname = model.LastName,
Email = model.UserName
};
db.Users.Add(dbUser);
db.SaveChanges();
var appUser = new ApplicationUser(model.UserName);
appUser.UserInfo = dbUser;
try
{
var result = await UserManager.CreateAsync(appUser, model.Password);
}
catch (Exception e)
{
db.Users.Remove(dbUser);
db.SaveChanges();
}
}
}
}
CreateUserAsync
方法给出以下错误:The entity type ApplicationUser is not part of the model for the current context.
The CreateUserAsync
-method gives the following error: The entity type ApplicationUser is not part of the model for the current context.
现在我的问题:
- 我是以"mvc"方式进行此操作吗?我觉得这对于我认为微不足道的事情来说是很多工作.
- 如果没有,是否有更好的方法来实现这一目标?
推荐答案
问题是您试图将添加到一个DbContext的用户添加到添加到不同DbContext(由UserManager创建)的ApplicationUser中.
The problem is that you're trying to add a User you added to one DbContext to a ApplicationUser you add to a different DbContext (created by the UserManager).
相反,您应该将其作为单个操作进行.只需这样做:
Instead, you should do this as a single operation. Just do this:
var dbUser = new User
{
Firstname = model.FirstName,
Lastname = model.LastName,
Email = model.UserName
};
var appUser = new ApplicationUser(model.UserName);
appUser.UserInfo = dbUser;
try
{
var result = await UserManager.CreateAsync(appUser, model.Password);
}
catch (Exception e)
{
// show error or whatever
}
