Question

我使用的是MVC，ASP Identity和EntityFramework。

我正在尝试制作自定义的ASP身份模型并让它与某些自定义表进行交互，我想扩展原始版本。

我一遍又一遍地得到同样的错误，现在已经尝试解决这个错误了整整2天。

错误如下：

One or more validation errors were detected during model generation:

Kportal.Models.IdentityUserLogin: : EntityType 'IdentityUserLogin' has no key defined. Define the key for this EntityType.
Kportal.Models.IdentityUserRole: : EntityType 'IdentityUserRole' has no key defined. Define the key for this EntityType.
IdentityUserLogins: EntityType: EntitySet 'IdentityUserLogins' is based on type 'IdentityUserLogin' that has no keys defined.
IdentityUserRoles: EntityType: EntitySet 'IdentityUserRoles' is based on type 'IdentityUserRole' that has no keys defined.

我已经尝试过在其他问题中找到的所有解决方案都无济于事，这已经慢慢变成了一场噩梦。

这是我的代码; 实体：IdentityDbContext

public class Entities : IdentityDbContext<ApplicationUsers, Role,
    int, UserLogin, ApplicationUserRole, UserClaim>
    {
        public Entities()
            : base("name=Entities")
        {
            Database.SetInitializer<Entities>(null);
            Configuration.LazyLoadingEnabled = false;
            Configuration.ProxyCreationEnabled = false;
        }

        public static Entities Create()
        {
            return new Entities();
        }

        //public virtual DbSet<ApplicationUsers> ApplicationUsers { get; set; }
        public virtual DbSet<Finding> Findings { get; set; }
        public virtual DbSet<Project> Projects { get; set; }
        //public virtual DbSet<Role> Roles { get; set; }
        public virtual DbSet<ApplicationUserProject> ApplicationUserProjects { get; set; }
        public virtual DbSet<ApplicationUserRole> ApplicationUserRoles { get; set; }
        public virtual DbSet<UserClaim> UserClaims { get; set; }
        public virtual DbSet<UserLogin> UserLogins { get; set; }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);

            modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
            modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();

            modelBuilder.Entity<IdentityUser>().Ignore(c => c.PhoneNumber)
                                          .Ignore(c => c.PhoneNumberConfirmed)
                                          .Ignore(c => c.TwoFactorEnabled)
                                          .Ignore(c => c.LockoutEndDateUtc)
                                          .Ignore(c => c.LockoutEnabled)
                                          .Ignore(c => c.AccessFailedCount)
                                          .Ignore(c => c.UserName);

            modelBuilder.Entity<IdentityUser>().ToTable("ApplicationUser", "dbo");
            modelBuilder.Entity<UserClaim>().ToTable("UserClaim", "dbo");
            modelBuilder.Entity<Role>().HasKey<int>(l => l.Id).ToTable("Role", "dbo");

            modelBuilder.Entity<UserLogin>().HasKey(l => new { l.LoginProvider, l.ProviderKey, l.UserId })
                                                  .ToTable("UserLogin", "dbo");
            modelBuilder.Entity<ApplicationUserRole>().HasKey(l => new { l.ApplicationUserId, l.RoleId })
                                                 .ToTable("ApplicationUserRole", "dbo");

            modelBuilder.Entity<ApplicationUsers>().Property(r => r.Id);
            modelBuilder.Entity<UserClaim>().Property(r => r.Id);
            modelBuilder.Entity<UserLogin>().Property(r => r.UserId);
            modelBuilder.Entity<Role>().Property(r => r.Id);
        }
    }

ApplicationUserRole：IdentityUserRole

public class ApplicationUserRole : IdentityUserRole<int>
    {
        public int ApplicationUserId { get; set; }
        public override int RoleId { get; set; }
        public System.DateTime DateCreated { get; set; }
        public System.DateTime DateChanged { get; set; }
        public int CreateUser { get; set; }
        public int ChangeUser { get; set; }

        public virtual ApplicationUsers ApplicationUser { get; set; }
        public virtual Role Role { get; set; }
    }

UserLogin：IdentityUserLogin

public class UserLogin : IdentityUserLogin<int>
{
    public string LoginProvider { get; set; }
    public string ProviderKey { get; set; }
    public int ApplicationUserId { get; set; }

    public virtual ApplicationUsers ApplicationUser { get; set; }
}

我希望这是足够的信息，为什么这些错误不断出现的任何线索？

您需要定义新自定义表的主键，例如：

[Key]
public int UserLoginId { get; set; }

如果您需要使用当前列的复合键，请使用：

[Key, Column(Order = 0)]
public string LoginProvider { get; set; }

[Key, Column(Order = 1)]
public string ProviderKey { get; set; }

[Key, Column(Order = 2)]
public int ApplicationUserId { get; set; }

EntityType＆＃39; IdentityUserLogin＆＃39;没有键定义/ EntityType＆＃39; IdentityUserRole＆＃39;没有定义键
