如何在控制器中修改更新方法

const express = require('express');
const router = express.Router();
const controller = require('./controller');

router.put('/items/:id', controller.updateItem);

module.exports = router;

const Item = require('./models/Item'); // 假设你有一个Item模型

exports.updateItem = async (req, res) => {
  try {
    const { id } = req.params;
    const updates = req.body;

    // 验证请求体
    if (!updates.name || !updates.description) {
      return res.status(400).json({ error: 'Name and description are required' });
    }

    // 查找并更新项目
    const item = await Item.findByIdAndUpdate(id, updates, { new: true });

    if (!item) {
      return res.status(404).json({ error: 'Item not found' });
    }

    res.status(200).json(item);
  } catch (error) {
    res.status(500).json({ error: 'Internal server error' });
  }
};

const mongoose = require('mongoose');

const itemSchema = new mongoose.Schema({
  name: String,
  description: String,
  createdAt: { type: Date, default: Date.now }
});

module.exports = mongoose.model('Item', itemSchema);
