UserManager.IsInRole returns 错误
UserManager.IsInRole returns false
我创建了一个种子用户，然后将其添加到角色 "SuperAdmin"。然而，当尝试从用户管理器执行 "IsInRole" 时，我总是得到 "false".
我已经按照我之前找到的答案中的建议打开了延迟加载，但没有成功。
在我的数据库中，我看到了 IdentityUserRole table 中的条目。它包含正确的用户标识和角色标识。 userId 与我的 ApplicationUser table
上的帐户 ID 匹配
注意：我确实将我的上下文和应用程序用户移出了 Web 项目并移到了我的 DAL 项目中
我的新上下文派生自 IdentityDbContext 并作为通用用户传入。我相信这与它有关，因为当我查看 table 'IdentityUserRole' 我看到以下列
用户ID |角色ID | ApplicationUser_ID | Role_ID
当我 运行 一个分析器时，我看到 entityframework 试图加入 ApplicationUser_ID 的角色。然而这是空的。 UserID 是填充的
我的控制器（returns false
var t = HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>();
//next line Fails due to FK, because user is already in role...
//t.AddToRole(User.Identity.GetUserId(), "SuperAdmin");
var users = UserManager.Users;
bool ffalse = t.IsInRole(User.Identity.GetUserId(), "SuperAdmin");
var false2 = User.IsInRole("SuperAdmin");
var false3 = UserManager.IsInRole(User.Identity.GetUserId(), "SuperAdmin");

所以，正如我上面所说，在使用探查器后，我发现角色没有正确加入用户。这让我找到了一种在创建模型时设置外键的方法。
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
Configuration.LazyLoadingEnabled = true;
var user = modelBuilder.Entity<ApplicationUser>()
.ToTable("AspNetUsers");
user.HasMany(u => u.Roles).WithRequired().HasForeignKey(ur => ur.UserId);
user.HasMany(u => u.Claims).WithRequired().HasForeignKey(uc => uc.UserId);
user.HasMany(u => u.Logins).WithRequired().HasForeignKey(ul => ul.UserId);
user.Property(u => u.UserName).IsRequired();
modelBuilder.Entity<IdentityUserRole>()
.HasKey(r => new { r.UserId, r.RoleId })
.ToTable("AspNetUserRoles");
modelBuilder.Entity<IdentityUserLogin>()
.HasKey(l => new { l.UserId, l.LoginProvider, l.ProviderKey })
.ToTable("AspNetUserLogins");
modelBuilder.Entity<IdentityUserClaim>()
.ToTable("AspNetUserClaims");
var role = modelBuilder.Entity<IdentityRole>()

role.Property(r => r.Name).IsRequired();
role.HasMany(r => r.Users).WithRequired().HasForeignKey(ur => ur.RoleId);
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
