我想知道是否有更好的方法來更新數組中的現有元素，而不是三次獲取數據庫。如果您有任何想法，我將不勝感激。謝謝！    const creatStock = async (symbol, webApiData) => {      try {        // reversed array        const webApiDataReversed = webApiData.reverse();        const query = { symbol };        const update = { $addToSet: { data: webApiDataReversed } };        const options = { upsert: true, new: true };        // create/update Stock        const stockResult = await Stock.findOneAndUpdate(query, update, options);        const lastElement = stockResult.data.length - 1;        const updatePull = {          $pull: { data: { date: stockResult.data[lastElement].date } },        };        // removes last date from data array        await Stock.findOneAndUpdate(query, updatePull);        // update Stock        await Stock.findOneAndUpdate(query, update);      } catch (ex) {        console.log(`creatStock error: ${ex}`.red);      }    };架構const ChildSchemaData = new mongoose.Schema({  _id: false,  date: { type: mongoose.Types.Decimal128 },  open: { type: mongoose.Types.Decimal128 },  high: { type: mongoose.Types.Decimal128 },  low: { type: mongoose.Types.Decimal128 },  close: { type: mongoose.Types.Decimal128 },  volume: { type: mongoose.Types.Decimal128 },});const ParentSchemaSymbol = new mongoose.Schema({  symbol: {    type: String,    unique: true,  },  // Array of subdocuments  data: [ChildSchemaData],});module.exports.Stock = mongoose.model('Stock', ParentSchemaSymbol);輸出
