AspNet Identity：如何更改默认表名而不影响角色授权

Question

我正在使用从nuget安装的AspNet IdentitySample项目。

安装后，我使用以下代码更改了默认表名：

   public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        public ApplicationDbContext()
            : base("DefaultConnection", throwIfV1Schema: false)
        {
        }

        static ApplicationDbContext()
        {
            // Set the database intializer which is run once during application start
            // This seeds the database with admin user credentials and admin role
            Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
        }

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

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

            modelBuilder.Entity<IdentityUser>().ToTable("Users");
            modelBuilder.Entity<ApplicationUser>().ToTable("Users");
            modelBuilder.Entity<IdentityUserRole>().ToTable("UserRoles");
            modelBuilder.Entity<IdentityUserLogin>().ToTable("UserLogins");
            modelBuilder.Entity<IdentityUserClaim>().ToTable("UserClaims");
            modelBuilder.Entity<IdentityRole>().ToTable("Roles");

        }
}

当我更改AspNet Identity默认表名时，User.IsInRole（＆＃34; Admin＆＃34;）和[Authorize（Roles =＆＃34; Admin＆＃34;）]始终返回false并且我无法访问UsersAdmin和RolesAdmin Pages。

虽然默认用户（admin@example.com）和角色（＆＃34; Admin＆＃34;）已经存在于生成的表格中（用户，角色和用户角色）。

还有其他什么需要改变吗？

更新

这是我的ApplicationDbInitializer类：

public class ApplicationDbInitializer : DropCreateDatabaseIfModelChanges<ApplicationDbContext> 
{
    protected override void Seed(ApplicationDbContext context) {
        InitializeIdentityForEF(context);
        base.Seed(context);
    }

    //Create User=Admin@Admin.com with password=Admin@123456 in the Admin role        
    public static void InitializeIdentityForEF(ApplicationDbContext db) {
        var userManager = HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>();
        var roleManager = HttpContext.Current.GetOwinContext().Get<ApplicationRoleManager>();
        const string name = "admin@example.com";
        const string password = "Admin@123456";
        const string roleName = "Admin";

        //Create Role Admin if it does not exist
        var role = roleManager.FindByName(roleName);
        if (role == null) {
            role = new IdentityRole(roleName);
            var roleresult = roleManager.Create(role);
        }

        var user = userManager.FindByName(name);
        if (user == null) {
            user = new ApplicationUser { UserName = name, Email = name };
            var result = userManager.Create(user, password);
            result = userManager.SetLockoutEnabled(user.Id, false);
        }

        // Add user admin to Role Admin if not already added
        var rolesForUser = userManager.GetRoles(user.Id);
        if (!rolesForUser.Contains(role.Name)) {
            var result = userManager.AddToRole(user.Id, role.Name);
        }
    }
}
