在某种情况下,您有一个用于创建名为User的基本模型的用户方案.然后对于用户角色,使用mongoose discriminators创建名为Admin,Employee和Client的继承模型.有没有办法以编程方式确定可用的用户模型有多少歧视/继承/角色,以及可用的名称？

var Schema = mongoose.Schema;

var options = {discriminatorKey: 'role'};

var userSchema = mongoose.Schema({
  name: String,
  email: String,
  password: String,

var Client = User.discriminator("Client", mongoose.Schema({
  Address : String,
  Tax_identification : String,
  Phone_number : String,
  Internal_Remarks : String,
  CRM_status : String,
  Recent_contact : String,
}));
var Employee = User.discriminator("Employee",mongoose.Schema({
  Staff_Id: String,
}));
