问题 This is probably a straightforward question. If so, please excuse me. I'm doing axios requests to nuxt, which does mongoose requests. For example, I have this function here: let aggregation = [ {$unwind: {path:"$versions"}}, {$match: {}}, {$group: { _id: "$_id", versions: {$push: {nlp : "$versions.nlp"} } } } ] scraps = await Scraps.aggregate(aggregation); However, I keep having this sort of errors: {"ok":0,"code":16945,"codeName":"Location16945","name":"MongoError"} Request failed with

问题 I am trying to use transactions to update multiple documents. One being a loading sheet document [await sheet.save({ session });] and other being an array of stock reservation records [await Stock.bulkWrite()]. const session = await mongoose.startSession(); session.startTransaction({ readPreference: 'primary', readConcern: { level: 'local' }, writeConcern: { w: 'majority' }, }); let sheetAfterSave: any = null; try { sheetAfterSave = await sheet.save({ session }); records.forEach(async (el:

问题 Last few days I spent learning MongoDB and MongooseJS, and the best technique that works for me is reading code, lots of code. Today I've stumbled upon on two interesting things that are not covered by any documentation, or maybe they are and I just can't find the right section. First thing I want to ask about is that ref property - what is it for? (I know it is offtopic, but when I set index property like in example below, will it help in searching Tags by User?) var TagSchema = new Schema({
