使用ABPzero的朋友们都知道，User表中有Name和Surname两个字段，这两个字段对于国内的用户来说相当的不友好。
以及我们的一些系统中是不会涉及到EmailAddress字段。也就是说不会使用邮箱来进行注册的，那么我们怎么解决了。

首先感谢群友https://github.com/maliming 提供的思路。

• 在abpzero中的AbpUser实体中Name和Surname、EmailAddress都是为必填。

        public override string ToString()
        {
            return string.Format("[User {0}] {1}", Id, UserName);
        }
    }
}

以上为ABPZERO源代码中的字段，我们怎么修改呢。

• 修改User实体信息。
  打开我们项目中的User.cs实体。

public class User : AbpUser<User>
    {
        public const string DefaultPassword = "123qwe";

        public static string CreateRandomPassword()
        {
            return Guid.NewGuid().ToString("N").Truncate(16);
        }

         
        private new string Name { get; set; }

        private new string Surname { get; set; }

        [Required(AllowEmptyStrings = true)]
        public override string EmailAddress { get; set; }


        public static User CreateTenantAdminUser(int tenantId, string emailAddress, string password)
        {
            return new User
            {
                TenantId = tenantId,
                UserName = AdminUserName,
         Name = AdminUserName,
                Surname = AdminUserName,
                EmailAddress = emailAddress,
                Password = new PasswordHasher().HashPassword(password)
            };
        }
    }

可以看到我将Name和SurName字段设置为private，这样设置之后，就有了值对象的感觉，EF在做实体验证的时候就不会对private的属性字段进行验证。
而Emailaddress因为涉及了很多的业务情况，我们不能将它设置为私有访问。

• 修改DbContext

我们打开'CMSDbContext.cs',添加方法

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

            modelBuilder.Entity<User>().Ignore(a => a.Name);
            modelBuilder.Entity<User>().Ignore(a => a.Surname);

            modelBuilder.Entity<User>().Property(a => a.EmailAddress).IsOptional();
            //   modelBuilder.Entity<User>().a => a.Name);

        }

覆盖方法‘OnModelCreating’，然后将Name和SurName设置为忽略。
然后将EmailAddress设置为可空。

• 执行迁移
  然后执行迁移文件命令:"add-migration Remove_Name_SurName".
  然后再执行"update-database"，生成的数据库中就不会有“Name”和“Surname”。
• 到目前为止，Name和SurName就不影响功能使用和开发了。

EmailAddress实体字段修改

   CheckErrors(await _userManager.CreateAsync(user));

在userManager领域服务中的CreateAsync提供的方法中，检查了EmailAddress 所以我们要重写方法。

修改后的'UserManager.cs'

  public class UserManager : AbpUserManager<Role, User>
    {
        private readonly IUnitOfWorkManager _unitOfWorkManager;

        public UserManager(
            UserStore userStore,
            RoleManager roleManager,
            IPermissionManager permissionManager,
            IUnitOfWorkManager unitOfWorkManager,
            ICacheManager cacheManager,
            IRepository<OrganizationUnit, long> organizationUnitRepository,
            IRepository<UserOrganizationUnit, long> userOrganizationUnitRepository,
            IOrganizationUnitSettings organizationUnitSettings,
            ILocalizationManager localizationManager,
            ISettingManager settingManager,
            IdentityEmailMessageService emailService,
            IUserTokenProviderAccessor userTokenProviderAccessor, IUnitOfWorkManager unitOfWorkManager1)
            : base(
                  userStore,
                  roleManager,
                  permissionManager,
                  unitOfWorkManager,
                  cacheManager,
                  organizationUnitRepository,
                  userOrganizationUnitRepository,
                  organizationUnitSettings,
                  localizationManager,
                  emailService,
                  settingManager,
                  userTokenProviderAccessor)
        {
            _unitOfWorkManager = unitOfWorkManager1;
        }


        public override async Task<IdentityResult> CheckDuplicateUsernameOrEmailAddressAsync(long? expectedUserId, string userName, string emailAddress)
        {
            var user = (await FindByNameAsync(userName));
            if (user != null && user.Id != expectedUserId)
            {
                return AbpIdentityResult.Failed(string.Format(L("Identity.DuplicateName"), userName));
            }

         
            return IdentityResult.Success;
        }

        private string L(string name)
        {
            return LocalizationManager.GetString(AbpZeroConsts.LocalizationSourceName, name);
        }

        public override async Task<IdentityResult> CreateAsync(User user)
        {
            var result = await CheckDuplicateUsernameOrEmailAddressAsync(user.Id, user.UserName, user.EmailAddress);
            if (!result.Succeeded)
            {
                return result;
            }

            user.EmailAddress = string.Empty;

            var tenantId = GetCurrentTenantId();
            if (tenantId.HasValue && !user.TenantId.HasValue)
            {
                user.TenantId = tenantId.Value;
            }

            try
            {
                return await base.CreateAsync(user);
            }
            catch (Exception e)
            {
                Console.WriteLine(e);
                throw;
            }
         
        }

        private int? GetCurrentTenantId()
        {
            if (_unitOfWorkManager.Current != null)
            {
                return _unitOfWorkManager.Current.GetTenantId();
            }

            return AbpSession.TenantId;
        }
    }

截止以上我们的功能EmailAddress功能就算正常了。

以下为旧文，大家可以自己对比观察。

使用ABPzero的朋友们都知道，User表中有Name和Surname两个字段，这两个字段对于国内的用户来说相当的不友好。

我们在尝试了很多的方法之后，发现无法完美将他们干掉。
所以尝试使用了一个比较不友好加流氓的方式来使用它。
如果你在使用的过程有更加美好的解决方案，可以提供给我们。
以及到https://github.com/aspnetboilerplate/module-zero/issues/337 这里提出方法。

开始流程：
首先到 "CMSDbContext.cs"中添加覆盖方法，找不到的如图所示：

Paste_Image.png

  protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {  
            base.OnModelCreating(modelBuilder);
            modelBuilder.Entity<User>().Ignore(a => a.Name);
            modelBuilder.Entity<User>().Ignore(a => a.Surname);       

        }

然后执行迁移文件命令:"add-migration Remove_Name_SurName".
然后再执行"update-database"，生成的数据库中就不会有“Name”和“Surname”。
但是坑爹的地方就在这，我们在执行Insert(User)方法的时候还是会报错。对于这种情况。我深深的感觉到了无力(感觉身体被Kid掏空)。
没有其他办法，只能暴力解决。在方法中，默认添加Name和Surname的值，只是为了绕过Eentityframework的实体验证。。
如下图所示。

Paste_Image.png

这样绕过之后，发现可以正常的处理信息。

User表中的Name和Surname也不在了。唯一不友好的地方就是坑爹。。

以上算是一个坑爹解决方法。
