在 ServiceStack.OrmLite 中更改表的别名运行时

Question

我有一个包含 IdentityDbContext 的应用程序，我想使用 ServiceStack.OrmLite 选择数据，我想知道如何更改别名

public class ApplicationDbContext : IdentityDbContext<User>
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
    }

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

        builder.Entity<User>().ToTable("User");
        builder.Entity<IdentityRole>().ToTable("Role");
        builder.Entity<IdentityUserRole<string>>().ToTable("UserRole");
        builder.Entity<IdentityUserClaim<string>>().ToTable("UserClaim");
        builder.Entity<IdentityUserLogin<string>>().ToTable("UserLogin");
    }
}

我尝试了下面的代码，但它不起作用：

ModelDefinition<User>.Definition.Alias = "Users";
ModelDefinition<IdentityRole>.Definition.Alias = "Roles";
ModelDefinition<IdentityUserRole<string>>.Definition.Alias = "UserRoles";
ModelDefinition<IdentityUserClaim<string>>.Definition.Alias = "UserClaims";
ModelDefinition<IdentityUserLogin<string>>.Definition.Alias = "UserLogins";

您可以使用 GetModelMetadata() 扩展方法更改 OrmLite 用于每种类型的表元数据，例如：

var tableMeta = type.GetModelMetadata();
tableMeta.Alias = "NewTableName";
