Mongodb .post unable to add data to the collection - mongodb

Question

I am trying to take user input and then add a drug(medicine) to MongoDB. But it is not working and I am getting the error "Add proper parameter first". The user input should be patient name, drug name, dosage, frequency, adherence, and reason for not taking medicine. Please help!
app.post("/add-drug", (req, res) => {
try {
if (req.body && req.body.patient_name && req.body.drug_name && req.body.dosage && req.body.frequency && req.body.adherence && req.body.reason) {
let new_drug = new drug();
new_drug.patient_name = req.body.patient_name
new_drug.drug_name = req.body.drug_name;
new_drug.dosage = req.body.dosage;
new_drug.frequency = req.body.frequency;
new_drug.adherence = req.body.adherence;
new_drug.reason = req.body.reason;
new_drug.user_id = req.user.id;
new_drug.save((err, data) => {
if (err) {
res.status(400).json({
errorMessage: err,
status: false
});
} else {
res.status(200).json({
status: true,
title: 'Drug Added successfully.'
});
}
});
} else {
res.status(400).json({
errorMessage: 'Add proper parameter first!',
status: false
});
}
} catch (e) {
res.status(400).json({
errorMessage: 'Something went wrong!',
status: false
});
}
});
The model file looks like this:
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
drugSchema = new Schema( {
patient_name: String,
drug_name: String,
dosage: Number,
frequency: Number,
adherence: Number,
reason: String,
user_id: Schema.ObjectId,
}),
drug = mongoose.model('drug', drugSchema);
module.exports = drug;

Answer 1

it is supposed to be <field>:<value> inside your app.post method, not <field>=<value>

Answer 2

The new_drug.save() method is asynchronous, so it returns a promise that you can await on:
app.post("/add-drug", async(req, res) => {
//...
await new_drug.save();
})
