问题 The following code works as expected to upload and retrieve files: // Mongo URI const mongoURI = 'mongodbconnstring'; // // Create mongo connection const conn = mongoose.createConnection(mongoURI); // // Init gfs let gfs; conn.once('open', () => { gfs = new mongoose.mongo.GridFSBucket(conn.db, { bucketName: 'Uploads' }); }); // Create storage engine const storage = new GridFsStorage({ url: mongoURI, file: (req, file) => { return new Promise((resolve, reject) => { const filename = file

问题 I am creating a model in typescript in mongoose and I would like to use a required function, however unlike normal javascript, I cannot use the 'this' operator as typescript doesn't recognize the scope. I would like to access the value of another one of the objects properties, but I am not sure how to do it. Here is what I am looking for: export interface IUser extends mongoose.Document { name: string; somethingElse?: number; }; export const UserSchema = new mongoose.Schema({ name: {type

问题 Consider the code below: const aux = await Fasta.find({}, "healthyTissue") .limit(1) .populate({ //---------------------first level (healthy or tumor fasta file) ---------------- path: "healthyTissue", model: "Hidden", options: { limit: 2 }, //--------------------- second level (hidden documents) ---------------- populate: { path: "children", options: { limit: 2 }, model: "FastaElement" } }); This is the output: The problem: just the first children is populated .

问题 I have a collection with a single document that contains many stats of different people. It is structured like so: // Stats list: [{ id: .... , lastUpdated: ... , stats: { Person1: {stat1: 0, stat2: 0, stat3: 0}, Person2: {stat1: 0, stat2: 0, stat3: 0}, ... Person100: {stat1: 0, stat2: 0, stat3: 0} } }] These stats are updated every 24 hours.

问题 In order to optimize the connection pool size, I thought it would make sense to graph query queue times. Is it possible to retrieve this metric from Mongoose? 回答1: See here for node monitoring. You need cmap events that apparently aren't documented there, see Ruby docs for example but they should be published by the node driver also. Track ConnectionCheckOutStarted and ConnectionCheckOutSucceeded and subtract the times to get the wait time. 来源： https://stackoverflow.com/questions/63652084

问题 I have Micro endpoints for my API that uses Mongoose. All of them work fine, except the one that uses .findOne(). This one returns the right data locally, but not when deployed to Now v2. Here is the endpoint: const { createError, run, send } = require("micro"); const mongoose = require("mongoose").set("debug", true); const mongooseConnect = require("./utils/mongooseConnect"); const Art = require("./schemas").art; mongooseConnect(); const art = async (req, res) => { console.log("hello world")
