如何在Identity RoleClaims表(asp网络核心)中添加新列 [英] How to add new colum into Identity RoleClaims table (asp net core)

问题描述

我试图在身份(asp网络核心)RoleClaims表中添加一列，但是我发现内容只是为了扩展角色和用户类，而不是RoleClaims.有人可以帮忙提供示例或指出内容吗?

I'm trying to add a column to the identity (asp net core) RoleClaims table but I find content just to extend the roles and users classes and not to RoleClaims. Could someone help with examples or point out content.

推荐答案

您将需要创建一个新类来扩展 RoleClaim .这是一个示例示例，如果您的密钥类型是 string :

You would need to create a new class to extend the RoleClaim. Here is an example of how to do it if your key type is string:

public class ApplicationRoleClaim : IdentityRoleClaim<string>
{
    public virtual ApplicationRole Role { get; set; }
}

您可以将任何想要的新属性添加到此类中，然后创建迁移以将它们添加为表列.

You can add whatever new properties you want to this class then create a migration to add them as table columns.

您还需要告诉您的 IdentityDbContext 也要使用此新类.这是文档中的示例:

You would also need to tell your IdentityDbContext to use this new class as well. Here is an example from the docs:

public class ApplicationDbContext
    : IdentityDbContext<
        ApplicationUser, ApplicationRole, string,
        ApplicationUserClaim, ApplicationUserRole, ApplicationUserLogin,
        ApplicationRoleClaim, ApplicationUserToken>
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
    }
}

使用自定义的 ApplicationRoleClaim 类，您也可以覆盖 OnModelCreating .这是来自文档的示例:

With your custom ApplicationRoleClaim class, you could override OnModelCreating as well. This is an example from the docs:

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    ⋮
    modelBuilder.Entity<IdentityRoleClaim<string>>(b =>
    {
        b.ToTable("MyRoleClaims");
    });
    ⋮
}
