Entity Framework 尝试 FindByName 时标识列名称“*_ID”无效

Question

我基于 Identity Framework 创建了我的应用程序，并创建了一个接口 ApplicationUser 以将 User_ID 类型设置为 GUID。一切正常，但是当我尝试使用 UserManager class 加载用户时，出现了一个我无法理解的异常。我不明白为什么要在命令中添加此列

异常：

ORA-00904: "Extent1"."ApplicationUser_Id": identificador inválido

导致异常的命令：

SELECT 
    "Extent1"."ID_USER_CLAIM" AS "ID_USER_CLAIM", 
    "Extent1"."ID_USER" AS "ID_USER", 
    "Extent1"."CLAIM_TYPE" AS "CLAIM_TYPE", 
    "Extent1"."CLAIM_VALUE" AS "CLAIM_VALUE", 
    "Extent1"."ApplicationUser_Id" AS "ApplicationUser_Id"
FROM 
    "BEECORE"."ADM_USER_CLAIM" "Extent1"
WHERE 
    ("Extent1"."ID_USER" = :p__linq__0)

代码：

var user = userService.UserManager.FindByName(model.UserName);

应用程序用户：

using Microsoft.AspNet.Identity.EntityFramework;
using System;

namespace Bee.Core.Domain.Identity
{
    public class ApplicationUser : IdentityUser<Guid, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
    {
        public ApplicationUser()
        {
            Id = Guid.NewGuid();
        }
        public ApplicationUser(string name) : this() { UserName = name; }
    }
}

配置：

using Bee.Core.Domain.Identity;
using System.Data.Entity.ModelConfiguration;

namespace Bee.Core.Administration.Data.EntityConfig.Identity
{
    public class IdentityUserConfiguration : EntityTypeConfiguration<ApplicationUser>
    {
        public IdentityUserConfiguration()
        {
            ToTable("ADM_USER");

            HasKey(c => new
            {
                c.Id
            });

            Property(c => c.Id).HasColumnName("ID_USER");
            Property(c => c.Email).HasColumnName("EMAIL");
            Property(c => c.EmailConfirmed).HasColumnName("EMAIL_CONFIRMED");
            Property(c => c.PasswordHash).HasColumnName("PASSWORD_HASH");
            Property(c => c.SecurityStamp).HasColumnName("SECURITY_STAMP");
            Property(c => c.PhoneNumber).HasColumnName("PHONE_NUMBER");
            Property(c => c.PhoneNumberConfirmed).HasColumnName("PHONE_NUMBER_CONFIRMED");
            Property(c => c.TwoFactorEnabled).HasColumnName("TWO_FACTOR_ENABLED");
            Property(c => c.LockoutEndDateUtc).HasColumnName("LOCKOUT_ENDDATEUTC");
            Property(c => c.LockoutEnabled).HasColumnName("LOCKOUT_ENABLED");
            Property(c => c.AccessFailedCount).HasColumnName("ACCESS_FAILED_COUNT");
            Property(c => c.UserName).HasColumnName("USER_NAME");
        }
    }
}

我在实施自定义 Microsoft Identity 时遇到了同样的问题。在这种情况下，我需要在 EntityTypeConfiguration 中为每个 Identity class/table.

显式配置所有外键

例如，您的代码需要进入 class 用户（继承 - IdentityUser）：

        HasMany(x => x.Claims)
                .WithRequired(y => y.ApplicationUser);
        HasMany(x => x.Roles)
                .WithRequired(y => y.ApplicationUser);
        HasMany(x => x.Logins)
                .WithRequired(y => y.ApplicationUser);

您需要使用外键配置所有 class Microsoft 身份：

Class UserClaim（继承 - IdentityUserClaim）：

        HasRequired(x => x.ApplicationUser)
                .WithMany(y => y.Claims)
                    .HasForeignKey(f => f.UserId);

Class 角色（继承 - IdentityRole）：

        HasMany(c => c.Users).WithRequired().HasForeignKey(c => c.RoleId);

Class UserLogin（继承 - IdentityUserLogin）：

        HasRequired(x => x.ApplicationUser)
                .WithMany(y => y.Logins)
                    .HasForeignKey(f => f.UserId);

Class UserRole（继承 - IdentityUserRole）：

        HasRequired(x => x.ApplicationUser)
                .WithMany(y => y.Roles)
                    .HasForeignKey(f => f.UserId);
