I'm trying to add commodity data to my stockrecord collection and if the commodity name is already in the stockrecord collection I just want to add the quantity of the commodity quantity to my stockrecord quantity.
but even their is existing data the, find method is returning an empty array
This my code
commodity.map(async (e) => {
const data = await new Commodity({
name: e.commodityName,
units: e.units,
quantity: e.quantity,
});
data.donator = donator;
await data.save();
const stock = await StockRecord.find({
name: {
$eq: e.commodityName,
},
});
//console.log(stock);
if (stock.length === 0) {
const record = await new StockRecord({
name: e.commodityName,
units: e.units,
quantity: parseFloat(e.quantity),
});
await record.save();
console.log(record);
} else {
console.log('may sulud');
stock[0].quantity += parseFloat(e.quantity);
await stock[0].save();
}
});
This is my stockrecord model
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const stockRecordSchema = new Schema({
name: {
type: String,
},
units: {
type: String,
enum: \['kg', 'pcs'\],
},
quantity: {
type: Number,
},
});
Array.map does not accept Promises
Try using for (const item of commodity) { //async magic here }
