EF Core 查询自定义IdentiyUser

Question

我对EF Core还是比较陌生，之前用过PetaPoco，所以请原谅我的无知。在我的数据库中，我将以下字段添加到我的 AspNetUsers table:

提升
已停用
名字
姓氏

然后我在 this blog article 之后创建了以下类：

public partial class ApplicationUser : IdentityUser
{
    public bool? Deactivated { get; set; }
    public bool? Elevated { get; set; }
    [StringLength(255)]
    public string FirstName { get; set; }
    [StringLength(255)]
    public string LastName { get; set; }
}

和

public class ApplicationClaimsPrincipalFactory : UserClaimsPrincipalFactory<ApplicationUser, IdentityRole>
{
    public ApplicationClaimsPrincipalFactory(UserManager<ApplicationUser> userManager, RoleManager<IdentityRole> roleManager, IOptions<IdentityOptions> optionsAccessor) : base(userManager, roleManager, optionsAccessor)
    { }

    public override async Task<ClaimsPrincipal> CreateAsync(ApplicationUser user)
    {
        var principal = await base.CreateAsync(user);

        if (!string.IsNullOrWhiteSpace(user.FirstName))
        {
            ((ClaimsIdentity)principal.Identity).AddClaims(new[] {
                new Claim(ClaimTypes.GivenName, user.FirstName)
            });
        }

        if (!string.IsNullOrWhiteSpace(user.LastName))
        {
            ((ClaimsIdentity)principal.Identity).AddClaims(new[] {
                new Claim(ClaimTypes.Surname, user.LastName)
            });
        }

        return principal;
    }
}

我还在 Startup.cs 文件中设置了 AddIdentity 和 AddScoped 方法。

从现在开始我不明白的是如何查询 table，返回我的自定义属性。在我的控制器中，我想做这样的事情：

/// <summary>
/// Gets every User.
/// </summary>
/// <returns>HTTP Result</returns>
[HttpGet]
[Route("")]
public async Task<ActionResult<IEnumerable<ApplicationUser>>> GetUsers()
{
    var users = await this._context.Users.Select(user => new
    {
        user.Id,
        user.Decativated,
        user.Elevated,
        user.Email,
        user.FirstName,
        user.LastName
    }).ToListAsync();

    return Ok(users);
}

但显然我不能，因为 Users DbSet 上不存在这些属性。

长话短说，我认为我已经正确设置了所有内容，但我如何实际查询我的扩展 IdentityUser？

编辑

应要求，以下是我的DbContext。我现在只有一个虚拟 table 接线，因为我只是试图让 AspNetUsers table 上的扩展首先工作：

public partial class [removed for confidentiality]Context : IdentityDbContext
{
    public [removed for confidentiality]Context()
    {
    }

    public [removed for confidentiality]Context(DbContextOptions<[removed for confidentiality]Context> options)
        : base(options)
    {
    }

    public virtual DbSet<Foo> Foos { get; set; }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        if (!optionsBuilder.IsConfigured)
        {
        }
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.HasAnnotation("ProductVersion", "[removed for confidentiality]");

        modelBuilder.Entity<Foo>(entity =>
        {
            entity.Property(e => e.FooName).IsUnicode(false);
        });

        OnModelCreatingPartial(modelBuilder);
    }

    partial void OnModelCreatingPartial(ModelBuilder modelBuilder);
}

您必须为 IdentityDbContext 指定类型参数。您需要继承自 IdentityDbContext<TUser> class。如果没有类型参数，您将使用 ASP.NET Core Identity 中定义的类。您想要更改的所有内容都必须反映在您的代码中。

public partial class [removed for confidentiality]Context : IdentityDbContext<ApplicationUser>
{
    public [removed for confidentiality]Context()
    {
    }

    public [removed for confidentiality]Context(DbContextOptions<[removed for confidentiality]Context> options)
        : base(options)
    {
    }

    public virtual DbSet<Foo> Foos { get; set; }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        if (!optionsBuilder.IsConfigured)
        {
        }
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.HasAnnotation("ProductVersion", "[removed for confidentiality]");

        modelBuilder.Entity<Foo>(entity =>
        {
            entity.Property(e => e.FooName).IsUnicode(false);
        });

        OnModelCreatingPartial(modelBuilder);
    }

    partial void OnModelCreatingPartial(ModelBuilder modelBuilder);
}
