自定义 ASP.NET 核心身份表

Question

当人在 asp.net 核心 2 中自定义身份 classes 时，表之间的关系不会自动创建。

如何以最简单的方式创建表之间的关系？

用户class:

public class User : IdentityUser<int>
{
    // codes
}

角色class:

public class Role : IdentityRole<int>
{
    public Role() : base()
    {

    }
    public Role(string roleName) : base(roleName)
    {

    }
}

角色声明class:

public class RoleClaim : IdentityRoleClaim<int> { }

用户声明class:

public class UserClaim : IdentityUserClaim<int> { }

用户登录class:

public class UserLogin : IdentityUserLogin<int> { }

用户角色class:

public class UserRole : IdentityUserRole<int> { }

用户令牌class:

public class UserToken : IdentityUserToken<int> { }

我想在我的表之间具有与此相同的关系：

Answer 1

有 IdentityDbContext 的泛型类型重载。如果您要自定义某些类，您必须通过这些重载告诉 Identity 实际使用哪些实体。由于您要自定义几乎所有内容，因此您需要最广泛的重载：

public class MyContext : IdentityDbContext<User, CustomRole, int, CustomUserClaim, CustomUserRole, CustomUserLogin, CustomRoleClaim, CustomUserLogin>

Answer 2

我通过在User、Role、UserClaim、UserRole、UserLogin、[=中编写一些代码来定义表的关系23=] 和 UserToken class 和 ApplicationDbContext class.

角色class:

public class Role : IdentityRole<int>
{
    public Role() : base()
    {

    }
    public Role(string roleName) : this()
    {
        Name = roleName;
    }

    public virtual ICollection<UserRole> Users { get; set; }
    public virtual ICollection<RoleClaim> Claims { get; set; }
}

角色声明class:

public class RoleClaim : IdentityRoleClaim<int>
{
    public virtual Role Role { get; set; }
}

用户class:

public class User : IdentityUser<int>
{
    public virtual ICollection<UserToken> UserTokens { get; set; }

    public virtual ICollection<UserRole> Roles { get; set; }

    public virtual ICollection<UserLogin> Logins { get; set; }

    public virtual ICollection<UserClaim> Claims { get; set; }
}

用户声明class:

public class UserClaim : IdentityUserClaim<int>
{
    public virtual User User { get; set; }
}

用户登录class:

public class UserLogin : IdentityUserLogin<int>
{
    public virtual User User { get; set; }
}

用户角色class:

public class UserRole : IdentityUserRole<int>
{
    public virtual User User { get; set; }
    public virtual Role Role { get; set; }
}

用户令牌class:

public class UserToken : IdentityUserToken<int>
{
    public virtual User User { get; set; }
}

ApplicationDbContext class:

public class ApplicationDbContext : IdentityDbContext<User, Role, int, UserClaim, UserRole, UserLogin, RoleClaim, UserToken>
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
    {

    }

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

        modelBuilder.Entity<RoleClaim>(builder =>
        {
            builder.HasOne(roleClaim => roleClaim.Role).WithMany(role => role.Claims).HasForeignKey(roleClaim => roleClaim.RoleId);
            builder.ToTable("RoleClaim");
        });
        modelBuilder.Entity<Role>(builder =>
        {
            builder.ToTable("Role");
        });
        modelBuilder.Entity<UserClaim>(builder =>
        {
            builder.HasOne(userClaim => userClaim.User).WithMany(user => user.Claims).HasForeignKey(userClaim => userClaim.UserId);
            builder.ToTable("UserClaim");
        });
        modelBuilder.Entity<UserLogin>(builder =>
        {
            builder.HasOne(userLogin => userLogin.User).WithMany(user => user.Logins).HasForeignKey(userLogin => userLogin.UserId);
            builder.ToTable("UserLogin");
        });
        modelBuilder.Entity<User>(builder =>
        {
            builder.ToTable("User");
        });
        modelBuilder.Entity<UserRole>(builder =>
        {
            builder.HasOne(userRole => userRole.Role).WithMany(role => role.Users).HasForeignKey(userRole => userRole.RoleId);
            builder.HasOne(userRole => userRole.User).WithMany(user => user.Roles).HasForeignKey(userRole => userRole.UserId);
            builder.ToTable("UserRole");
        });
        modelBuilder.Entity<UserToken>(builder =>
        {
            builder.HasOne(userToken => userToken.User).WithMany(user => user.UserTokens).HasForeignKey(userToken => userToken.UserId);
            builder.ToTable("UserToken");
        });
    }
}
