我正在尝试使用mongoose来创建数据库和集合.我的代码是:

var mongoose = require('mongoose');
    var db = mongoose.connect('mongodb://localhost/testdb');
    var Schema = mongoose.Schema;

    var UserInfo = new Schema({
    username : String,
    password : String 
    });

    mongoose.model('UserInfo', UserInfo);

    var user = db.model('UserInfo');


    var admin = new user();
    admin.username = "sss";
    admin.password = "ee";
    admin.save();

当我运行此代码时,mongoose创建了名为UserInfo而不是userinfo的集合.如何在mongoose中强制收集名称？
