AddToRole和IdentityRole不是当前上下文模型的一部分 [英] AddToRole and IdentityRole is not part of the model for the current context

问题描述

我使用Identity 2.1来处理我的asp.net应用程序的用户角色。到目前为止好，我创造了新的环境，从IdentityDBContext延长，延长IdentityUser和IdentityRole添加了几个新的领域。但是，每当我尝试使用的UserManager即时得到用户添加到特定角色的 的实体类型IdentityRole是不是该机型为当前上下文的一部分。 。因此，似乎有一些错误的用户角色的关系，这是我的code，到目前为止，以供参考：

I'm using Identity 2.1 to handle the user roles in my asp.net application. So far so good, i created new context extending from IdentityDBContext, extending the IdentityUser and IdentityRole to add a couple of new fields. However, whenever im trying to add a user to a specific role using the UserManager im getting The entity type IdentityRole is not part of the model for the current context.. So there seem to be something wrong with the user-role relationship, here is my code so far for reference:

用户

public class User : IdentityUser{

    public string Name { get; set; }
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<User> manager, string authenticationType) {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, authenticationType);
        // Add custom user claims here
        return userIdentity;
    }
}

角色

public partial class Role : IdentityRole
{
    public string Description { get; set; }
}

的DB上下文

namespace Carbon.Models {

    public partial class CarbonEDM :  IdentityDbContext<User, Role, string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>{
        public CarbonEDM()
            : base("name=CarbonDB") {
        }

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

        protected override void OnModelCreating(DbModelBuilder modelBuilder) {

            base.OnModelCreating(modelBuilder);

            modelBuilder.Entity<User>().ToTable("Users", "dbo");
            modelBuilder.Entity<Role>().ToTable("Roles", "dbo");
            modelBuilder.Entity<IdentityUserRole>().ToTable("UserRoles", "dbo");
            modelBuilder.Entity<IdentityUserClaim>().ToTable("UserClaims", "dbo");
            modelBuilder.Entity<IdentityUserLogin>().ToTable("UserLogins", "dbo");
        }
    }
}

ApplicationUserManager

public class ApplicationUserManager : UserManager<User>
{
    public ApplicationUserManager(IUserStore<User> store)
        : base(store)
    {
    }

    public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context) 
    {

        var manager = new ApplicationUserManager(new UserStore<User>(context.Get<CarbonEDM>()));
        // Configure validation logic for usernames
        manager.UserValidator = new UserValidator<User>(manager)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };

        // Configure validation logic for passwords
        manager.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 6,
            RequireNonLetterOrDigit = false,
            RequireDigit = false,
            RequireLowercase = false,
            RequireUppercase = false,
        };

        // Configure user lockout defaults
        manager.UserLockoutEnabledByDefault = true;
        manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
        manager.MaxFailedAccessAttemptsBeforeLockout = 5;

        var dataProtectionProvider = options.DataProtectionProvider;
        if (dataProtectionProvider != null)
        {
            manager.UserTokenProvider = 
                new DataProtectorTokenProvider<User>(dataProtectionProvider.Create("ASP.NET Identity"));
        }
        return manager;
    }
}

最后，错误我得到每当迁移IM播种：

And finally, the error am getting whenever im seeding in the migration:

    protected override void Seed(Carbon.Models.CarbonEDM context)
    {

        DbContextTransaction transaction = null;
        transaction = context.Database.BeginTransaction();

        if (!context.Roles.Any()) {
            var roleStore = new RoleStore<Role>(context);
            var roleManager = new RoleManager<Role>(roleStore);

            roleManager.Create(new Role { Name = "Admin" });
            roleManager.Create(new Role { Name = "Control Unit Operator" });
            roleManager.Create(new Role { Name = "Lab Operator" });
            roleManager.Create(new Role { Name = "Production Engineer" });
            roleManager.Create(new Role { Name = "Production Operator" });
        }

        if (!context.Users.Any()) {
            var userStore = new UserStore<User>(context);
            var userManager = new ApplicationUserManager(userStore);

            var _user = new User {
                Email = "[e-mail]",
                PhoneNumber = "[phone]",
                Name = "Yehia A.Salam",
                UserName = "[e-mail]"
            };
            userManager.Create(_user, "pass@word");
            userManager.AddToRole(_user.Id, "Admin"); /* IdentityRole error here */

        }

        context.SaveChanges();
        transaction.Commit();


        base.Seed(context);
    }
}

对不起，长的帖子，我想包括一切。

Sorry for the long post, I tried to include everything.

推荐答案

好了，所以这个问题是与UserStore，默认的申报

okay so the problem was with the UserStore, the default declaration was

public class UserStore<TUser> : UserStore<TUser, IdentityRole, string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>, IUserStore<TUser>, IUserStore<TUser, string>, IDisposable where TUser : Microsoft.AspNet.Identity.EntityFramework.IdentityUser {

具有IdentityRole显式声明，而不是使用通用符号像TUSER使得它，所以我们只需要创建从父UserStore扩展另一个类：

which have IdentityRole explicitly declared instead of making it using the generic notation like TUser, so we just need to create another class extending from the parent UserStore:

public class CarbonUserStore<TUser> : UserStore<TUser, Role, string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>, IUserStore<TUser>, IUserStore<TUser, string>, IDisposable where TUser : Microsoft.AspNet.Identity.EntityFramework.IdentityUser {

    public CarbonUserStore(DbContext context) :base(context) {}     }

不冷静微软，我花了一天时间试图弄清楚它等待。然而，它的加入与vNext（得爱它白令开源）标识包运费：

public class UserStore<TUser, TRole, TContext> : UserStore<TUser, TRole, TContext, string>
    where TUser : IdentityUser, new()
    where TRole : IdentityRole, new()
    where TContext : DbContext
{
    public UserStore(TContext context, IdentityErrorDescriber describer = null) : base(context, describer) { }
}
