   auto query = em.createQuery!UserInfo("select u from UserInfo u");
   auto uinfos = query.getResultList();
   foreach(u;uinfos)
   {
     auto result = u.valid();

    if (result.isValid() == false)
    {
        import std.stdio : writeln;
        foreach(key, message; result.messages())
        {
            writeln("%s: %s", key, message);
        }
    }
    }
