DiscordJS/MongoDB如何让bot正确更新值

// models/User.js
const mongoose = require('mongoose');

const userSchema = new mongoose.Schema({
    userId: { type: String, required: true, unique: true },
    points: { type: Number, default: 0 }
});

module.exports = mongoose.model('User', userSchema);

// index.js
const mongoose = require('mongoose');
const { Client, Intents } = require('discord.js');
const client = new Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES] });

const mongoURI = 'your_mongodb_connection_string_here';

mongoose.connect(mongoURI, {
    useNewUrlParser: true,
    useUnifiedTopology: true,
    useFindAndModify: false
}).then(() => {
    console.log('Connected to MongoDB');
}).catch(err => {
    console.error('Failed to connect to MongoDB', err);
});

client.once('ready', () => {
    console.log(`Logged in as ${client.user.tag}`);
});

client.login('your_discord_bot_token_here');

// index.js (继续)
const User = require('./models/User');

client.on('messageCreate', async message => {
    if (message.content.startsWith('!addpoints')) {
        const userId = message.author.id;
        const pointsToAdd = parseInt(message.content.split(' ')[1], 10);

        if (isNaN(pointsToAdd)) {
            return message.reply('Please provide a valid number of points.');
        }

        try {
            let user = await User.findOne({ userId });

            if (!user) {
                user = new User({ userId, points: 0 });
            }

            user.points += pointsToAdd;
            await user.save();

            message.reply(`You have been awarded ${pointsToAdd} points. You now have ${user.points} points.`);
        } catch (err) {
            console.error('Error updating points:', err);
            message.reply('There was an error updating your points. Please try again later.');
        }
    }
});
