自定义ASP.NET标识时出错 - “ApplicationUser不是当前上下文模型的一部分”

I have read lots of other posts/discussions regarding this error and have not found a clear answer.

我已经阅读了很多关于此错误的其他帖子/讨论,但没有找到明确的答案。

I have customised ASP.NET Identity to store FirstName and Country as well as username/password/email address, and I'm now having issues actually storing this within the generated tables within my database.

我已经定制了ASP.NET身份来存储FirstName和Country以及用户名/密码/电子邮件地址,而我现在遇到的问题实际上是在我的数据库中生成的表中存储它。

I have already enabled migrations, added a migration and updated the database to reflect the 2 additional fields within my Identity.

我已经启用了迁移,添加了迁移并更新了数据库以反映我的标识中的2个附加字段。

Error at IdentityResult result = manager.Create(user, model.Password);

IdentityResult的错误结果= manager.Create(user,model.Password);

$exception  {"The entity type ApplicationUser is not part of the model for the current context."}   System.Exception {System.InvalidOperationException}

web.config:

<connectionStrings>
    <remove name="DefaultConnection" />
    <add name="DefaultConnection" providerName="System.Data.SqlClient" connectionString="Data Source=WIN8-SUNEETAGU\SQLSERVER;Initial Catalog=UnderConstruction;Integrated Security=True" />

2 个解决方案

I'm thinking it has to do with the nested classes within AuthenticationModels.cs. I'd try moving them outside of the AuthenticationModels class. Example:

我认为它与AuthenticationModels.cs中的嵌套类有关。我尝试将它们移出AuthenticationModels类之外。例:

namespace UnderConstruction.Models.AuthenticationModels
{
    public class ApplicationUser : IdentityUser
    {
        public string FirstName { get; set; }

        public string Country { get; set; }
    }

    public class ApplicationDbContext : IdentityDbContext<UnderConstruction.Models.AuthenticationModels.ApplicationUser>
    {
        public ApplicationDbContext()

            : base("DefaultConnection")
        {}
    }

    public class RegisterModel
    {
        [Required]
        [StringLength(10, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 5)]
        [Display(Name = "Username")]
        public string Username { get; set; }

        [Required]
        [StringLength(10, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 4)]
        [DataType(DataType.Password)]
        [Display(Name = "Password")]
        public string Password { get; set; }

        [Required]
        [StringLength(10, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 4)]
        [DataType(DataType.Password)]
        [Display(Name = "Confirm password")]
        public string ConfirmPassword { get; set; }

        [Required]
        [DataType(DataType.EmailAddress)]
        [EmailAddress(ErrorMessage="Please enter a valid email address.")]
        [Display(Name = "Email address")]
        public string Email { get; set; }

        [Required]
        [StringLength(10, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 5)]
        [Display(Name = "First name")]
        public string FirstName { get; set; }

        [Required]
        [StringLength(50)]
        [Display(Name = "Country")]
        public string Country { get; set; }
    }   
}

I just moved everything into the UnderConstruction.Models.AuthenticationModels namespace, instead of having to create an instance of the AuthenticationModels class.

我只是将所有内容都移到了UnderConstruction.Models.AuthenticationModels命名空间中,而不必创建AuthenticationModels类的实例。

Maybe I've found a solution. Check the UserManager initialization in Startup.Auth.cs to be like this

也许我找到了解决方案。检查Startup.Auth.cs中的UserManager初始化是这样的

UserManagerFactory = () => new UserManager<User>(new UserStore<User>(new MyContext()));
