实体类型IdentityUser不是当前上下文的模型的一部分 [英] The entity type IdentityUser is not part of the model for the current context
问题描述
我看到与这个的问题,但是在这里提出的方案似乎不适用,所以我认为我有一个不同的问题。事实上,我在SO上看到几个类似的问题,每个问题都有不同的原因和解决方案,所以我认为这个错误必须从高层次引起。这就是说...
I am seeing the same issue as this question, but the scenario presented there doesnt seem to apply so I think I have a different issue. In fact, I'm seeing several questions on SO that are similar, each with different causes and solutions, so I think this error must be caused from a high level. That said...
我有一个EF代码优先的数据库模型,我试图使用 IdentityUser
扩展我的MVC 5网站的标准注册。
I have an EF code-first database model and I'm trying to use IdentityUser
to extend a standard registration for my MVC 5 site.
我有扩展的 UserModel
:
namespace MyMvcSite.Models {
public class UserModel :IdentityUser {
public string BillingId { get; set; }
public virtual ICollection<DatabaseModel> Databases { get; set; }
}
我的上下文:
using MyMvcSite.Models;
namespace MyMvcSite.Web {
public class AuthContext : IdentityDbContext<UserModel> {
public AuthContext() : base("AuthContext") {
}
}
}
现在,当我执行注册用户的代码时:
Now, when I execute the code to register a user:
public async Task<IdentityResult> RegisterUser(UserModel user) {
user.Email = user.UserName;
var result = await _userManager.CreateAsync(user);
return result;
}
我收到错误:实体类型IdentityUser是不是当前上下文的模型的一部分。
我不知道这个错误是什么意思,因为它看起来像我一样 - 就像我有一切正确。有谁可以告诉可能出了什么问题?
I get the error: The entity type IdentityUser is not part of the model for the current context.
I can't figure out what this error means, because it looks - to me - like I have everything correct. Can anyone tell what might be going wrong???
我知道我的connectionString AuthContext
是正确的,因为我已经使用
I know my connectionString AuthContext
is correct because I have used it previously.
推荐答案
当您使用具有ASP.NET身份的自定义用户类时,必须确保您明确在 UserManager
和 UserStore c中指定自定义用户类类型
< T>
/ code>实例化。
When you are using a custom user class with ASP.NET Identity, you have to make sure that you explicitly specify the custom user class type <T>
to both the UserManager
and the UserStore
on instantiation.
private UserManager<UserModel> _userManager;
public AccountController()
{
AuthContext _ctx = new AuthContext();
UserStore<UserModel> userStore = new UserStore<UserModel>(_ctx);
_userManager = new UserManager<UserModel>(userStore);
}
或更短的形式(如您的回复评论):
or in shorter form (like your reply comment):
private UserManager<UserModel> _userManager;
public AccountController()
{
AuthContext _ctx = new AuthContext();
_userManager = new UserManager<UserModel>(new UserStore<UserModel>(_ctx));
}
如果允许该类型默认为 IdentityUser
当您想使用自定义类时,您将遇到您报告的错误。
If the type is allowed to defaulted to IdentityUser
when you want to use a custom class you will experience the error you reported.
