如何使用int ID列更改ASP.net Identity 2.0的表名？

Question

我已经使用ASP.net会员多年,我刚刚开始尝试ASP.net身份.他们刚刚发布了2.0版,它应该支持int主键.我已经定义了我的自定义标识类,以获得整数主键支持:

public class User : IdentityUser<int, UserLogin, UserRole, UserClaim>
{  
}

public class UserLogin : IdentityUserLogin<int>
{
}

public class Role : IdentityRole<int, UserRole>
{
    public string Description { get; set; }  // Custom description field on roles
}

public class UserRole : IdentityUserRole<int>
{
}

public class UserClaim : IdentityUserClaim<int>
{
}

public class MyDbContext : IdentityDbContext<User, Role, int, UserLogin, UserRole, UserClaim>
{
    public MyDbContext() : this("MyDB") { }

    public MyDbContext(string connStringName) : base(connStringName)
    {
        this.Configuration.LazyLoadingEnabled = false;
        this.Configuration.ProxyCreationEnabled = false;
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {

        modelBuilder.Entity<User>().ToTable("Users");
        modelBuilder.Entity<Role>().ToTable("Roles");
        modelBuilder.Entity<UserRole>().ToTable("UserRoles");
        modelBuilder.Entity<UserLogin>().ToTable("UserLogins");
        modelBuilder.Entity<UserClaim>().ToTable("UserClaims");

        base.OnModelCreating(modelBuilder);
    }
}

当我创建数据库迁移时,它会为每个标识表正确创建一个整数Id列,但是,它忽略了我在OnModelCreating方法中指定的自定义表名.相反,我得到像dbo.AspNetUsers和的表名dbo.AspNetRoles.

我也尝试添加[Table("TableName")]到我的自定义标识类,它没有任何效果.

在查看ASP.net Identity 1.0的示例时,看起来他们modelBuilder.Entry<Type>().ToTable("TableName")使用基本Identity类重复了每一行:

modelBuilder.Entity<User>().ToTable("Users");
modelBuilder.Entity<IdentityUser<int, IdentityUserLogin<int>, IdentityUserRole<int>, IdentityUserClaim<int>>>().ToTable("Users");

modelBuilder.Entity<Role>().ToTable("Roles");
modelBuilder.Entity<IdentityRole<int, UserRole>>().ToTable("Roles");

modelBuilder.Entity<UserRole>().ToTable("UserRoles");
modelBuilder.Entity<IdentityUserRole<int>>().ToTable("UserRoles");

modelBuilder.Entity<UserLogin>().ToTable("UserLogins");
modelBuilder.Entity<IdentityUserLogin<int>>().ToTable("UserLogins");

modelBuilder.Entity<UserClaim>().ToTable("UserClaims");
modelBuilder.Entity<IdentityUserClaim<int>>().ToTable("UserClaims");

但是,我尝试了几种变体,我的迁移不会生成.我一直收到类似于Microsoft.AspNet.Identity.EntityFramework.IdentityUser'4类型的错误[System.Int32,Microsoft.AspNet.Identity.EntityFramework.IdentityUserLogin'1 [System.Int32],Microsoft.AspNet.Identity.EntityFramework.IdentityUserRole '1 [System.Int32],Microsoft.AspNet.Identity.EntityFramework.IdentityUserClaim'1 [System.Int32]]'未映射.使用Ignore方法或NotMappedAttribute数据批注检查未明确排除类型.验证类型是否已定义为类,不是原始类型还是通用类型,并且不从EntityObject继承.

如何在ASP.net Identity 2.0中生成带有整数主键的自定义表名？

Answer 1

Grrr ......所以在浪费了几个小时之后,我复制了我的规则并将它们粘贴base.OnModelCreating(modelBuilder);在线下,一切正常.我没有意识到需要首先调用基本方法:(

现在使用以下配置一切正常:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    base.OnModelCreating(modelBuilder); // This needs to go before the other rules!

    modelBuilder.Entity<User>().ToTable("Users");
    modelBuilder.Entity<Role>().ToTable("Roles");
    modelBuilder.Entity<UserRole>().ToTable("UserRoles");
    modelBuilder.Entity<UserLogin>().ToTable("UserLogins");
    modelBuilder.Entity<UserClaim>().ToTable("UserClaims");
}

Answer 2

在IdentityModel.cs文件中,我将以下代码添加到ApplicationDbContext类中

请注意,模型名称与接受的答案中列出的名称不同

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

        modelBuilder.Entity<ApplicationUser>().ToTable("SystemUsers");
        modelBuilder.Entity<IdentityRole>().ToTable("SystemRoles");
        modelBuilder.Entity<IdentityUserRole>().ToTable("SystemUserRoles");
        modelBuilder.Entity<IdentityUserLogin>().ToTable("SystemUserLogins");
        modelBuilder.Entity<IdentityUserClaim>().ToTable("SystemUserClaims");
    }
