Question

在我们的DbContext.cs上有这个（模型构建器）代码

 base.OnModelCreating(modelBuilder);
 modelBuilder.Entity<IdentityUserLogin>().HasKey<string>(l => l.UserId);
 modelBuilder.Entity<IdentityRole>().HasKey<string>(r => r.Id);
 modelBuilder.Entity<IdentityUserRole>().HasKey(r => new { r.RoleId, r.UserId });
 modelBuilder.Entity<ApplicationUser>().ToTable("ApplicationUser");

除授权/用户角色外，一切正常。

检查完所有表后，我注意到 IdentityUserRoles 表创建了4列： RoleId，UserId，IdentityRole_Id和ApplicationUser_Id。

我发现， IdentityRole_Id和ApplicationUser_Id [外键]被映射或使用，而不是 RoleId和UserId [主键]。不幸的是，身份（Id）数据被插入到RoleId / UserId列中，IdenityRole_Id / ApplicationUser_Id默认为 NULL 。

请帮忙。

我的代码：

public class RqDbContext : DbContext
{
    private const string ConnectionString = "RqDbContext";

    public RqDbContext() : base(ConnectionString)
    {
    }
    public static RqDbContext Create()
    {
        return new RqDbContext();
    }

    }

下面的代码将修复IdentityUserRoles表外键问题。

var user = modelBuilder.Entity<TUser>()
    .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<TUserRole>()
    .HasKey(r => new { r.UserId, r.RoleId })
    .ToTable("AspNetUserRoles");

modelBuilder.Entity<TUserLogin>()
    .HasKey(l => new { l.UserId, l.LoginProvider, l.ProviderKey})
    .ToTable("AspNetUserLogins");

modelBuilder.Entity<TUserClaim>()
    .ToTable("AspNetUserClaims");

var role = modelBuilder.Entity<TRole>()
    .ToTable("AspNetRoles");
role.Property(r => r.Name).IsRequired();
role.HasMany(r => r.Users).WithRequired().HasForeignKey(ur => ur.RoleId);

我在这里找到了答案。 Create ASP.NET Identity tables using SQL script！

用户角色/授权在ASP.NET身份中不起作用
