So I getting some information in a form.
So I wanna get the information from the form p.x a name and use it to name an array in a schema I am creating.
Here is what i kinda wanna do:
app.post('/edit-rooms', (req, res, next) =>{
const Accomodation = require('../models/accomodation')
Accomodation.findOne({email: req.session.passport.user}).lean().exec((err, user) => {
if (err) {
console.log(err, null);
}
if (user) {
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const AccomSchema = new Schema ({req.body.roomsleft : Array})
const Accomodation = mongoose.model('accomodation', AccomSchema);
Accomodation.update({
roomsleft: req.body.roomsleft,
{req.body.roomsleft}: {
roomnum: req.body.roomnumber,
single: req.body.single,
double: req.body.double,
king: req.body.king,
superking: req.body.superking,
bunk: req.body.bunk,
sofa: req.body.sofa,
button: req.body.button,
},
upsert: true
})
.exec()
}
})
})
So as you see i am getting a name from the body and trying to using it as the name of the array.
But obviously that doesn't work.
Does anyone know how I am supposed to do that correctly?

I'm quite new to Javascript, normally a Python person. I've looked at some other answers but my embed does not add the fields as expected. The embed itself is sent.
My Discord bot follows the guide provided by the devs (primary file, slash commands, command files). I am trying to loop through the entries in an SQLite query and add them as fields.
My command file is below.
const { SlashCommandBuilder } = require('#discordjs/builders');
const { MessageEmbed } = require('discord.js')
const sqlite = require('sqlite3').verbose();
module.exports = {
data: new SlashCommandBuilder()
.setName('rank')
.setDescription('Rank all points.'),
async execute(interaction) {
const rankEmbed = new MessageEmbed()
.setColor('#0099ff')
.setTitle('Rank Board')
let db = new sqlite.Database('./databases/ranktest.db', sqlite.OPEN_READWRITE);
let queryall = 'SELECT name, points FROM pointstable ORDER BY points DESC'
db.all(queryall, [], (err, rows) => {
if (err) {
console.log('There was an error');
} else {
rows.forEach((row) => {
console.log(row.name, row.points)
rankEmbed.addField('\u200b', `${row.name}: ${row.points}`, true);
});
}
})
return interaction.reply({embeds: [ rankEmbed ] });
}
}
I would also like to convert row.name - held as Discord IDs - to usernames i.e. MYNAME#0001. How do I do this by interaction? I was able to obtain the User ID in another command by using interaction.member.id, but in this case I need to grab them from the guild. In Python I did this with await client.fetch_user but in this case the error await is only valid in async functions and the top level bodies of modules is thrown.
Thanks.
OK I've solved the first aspect, I had the return interaction.reply in the wrong place.
Relevant snippet:
rows.forEach((row) => {
console.log(row.name, row.points)
rankEmbed.addField('\u200b', `${row.name}: ${row.points}`, false);
})
return interaction.reply({embeds: [rankEmbed ]} );
Would still appreciate an answer to the converting row.name (user ID) to user name via fetch.
I've solved the second aspect also. Add the below into the loop.
rows.forEach((row) => {
let client = interaction.client
const uname = client.users.cache.get(row.name);
rankEmbed.addField('\u200b', `${uname}: ${row.points}`, false);
Please help me understand how can i call that ping.js from user input, like if a user type ping it will Trigger cuz of the aliases but if a user types a full phrase it won't trigger.
Or in a non headic question how can i implent this to work -> if (message.content.includes('ping'))
Sorry in advance and thanks a lot
ping.js
const Discord = require('discord.js')
const colors = require('../lib/colors.json')
exports.run = async (client, message, args, level) => {
try {
const pingEmbed = new Discord.RichEmbed()
.setColor(colors.default)
.setFooter('ping)
.addField(`${message.author.id}`, 'hey')
const msg = await message.channel.send(pingEmbed)
const embed = new Discord.RichEmbed()
.setColor(colors.default)
.addField('...',
`${msg.createdTimestamp - message.createdTimestamp}ms`)
msg.edit(embed)
} catch (err) {
message.channel.send('There was an error!\n' + err).catch()
}
}
exports.conf = {
enabled: true,
aliases: ['ping'],
guildOnly: false,
permLevel: 'User'
}
exports.help = {
name: 'ping,
category: 'tools,
description: 'ping pong',
usage: 'ping'
}
If you want to check whether a message contains any of the aliases you can just use Array.some() like this:
let aliases = ['your', 'command', 'aliases']
client.on('message', message => {
if (aliases.some(trigger => message.content.includes(trigger))) {
// The message includes at least one of your keywords
}
})
In this example is just declared aliases, but you can use the array from your command and integrate this method in your normal command handler.
Got a component in AngularJS (porting soon to Angular 7) for updating a user profile that invokes an AngularJS service method to perform a PUT to /api/user/:id.
Want to add a small photo (<100K) to send in the same PUT with the other fields then handle the request like this in the controller...
// route: PUT /api/user/:id
import db from '../../utils/db';
export async function upsert(req, res) {
const { id, name, phone, email, photo } = req.body;
// users.photo in PostgreSQL has datatype of bytea
const sql = `UPDATE users SET name = $2, phone = $3, email = $4, photo = $5) WHERE id = $1 RETURNING id, name, phone, email, photo;`;
const { rows } = db.query(sql, [id, name, phone, email, photo];
return res.status(200).send(rows);
}
Is there a clean way to encode the image client-side so it can be included in the JSON the AngularJS service PUTs? Other solutions I found seem like overkill for this use-case - requiring the image upload to be handled very differently from the other fields.
Ended up biting the bullet - creating a separate table for files along with its own API using formidable and node-postgres. In case this helps anyone else, here's how it turned out.
PostgreSQL data definition...
-- DROP SEQUENCE public.files_seq;
CREATE SEQUENCE IF NOT EXISTS public.files_seq;
-- DROP TABLE public.files;
CREATE TABLE IF NOT EXISTS public.files (
_id integer PRIMARY KEY DEFAULT nextval('files_seq'::regclass),
name character varying(512) NOT NULL,
type character varying(20) NOT NULL,
data bytea
);
-- DROP INDEX public.users_first_name;
CREATE INDEX files_name ON public.files USING btree (name);
Controller for Express...
import stream from 'stream';
import fs from 'fs';
import { IncomingForm } from 'formidable';
import db from '../../utils/db';
// Returns list of images
export async function index(req, res) {
const { rows } = await db.query('SELECT _id, name, type FROM files ORDER BY name;', []);
return res.send(rows);
}
// Uploads a single file
export async function upload(req, res) {
let _id;
new IncomingForm().parse(req, (err, fields, files) => {
if(err) throw err;
if(Array.isArray(files)) throw new Error('Only one file can be uploaded at a time');
const { name, type, path } = files.file;
fs.readFile(path, 'hex', async(err, fileData) => {
if(err) throw err;
fileData = `\\x${fileData}`;
const sql = 'INSERT INTO files (name, type, data) VALUES($1, $2, $3) RETURNING _id;';
const { rows } = await db.query(sql, [name, type, fileData]);
_id = rows[0]._id;
res.send({ id: _id });
// console.log(`Uploaded ${name} to ${path} and inserted into database (ID = ${_id})`);
// No need to delete the file uploaded as Heroku has an ephemeral file system
});
});
}
// Downloads a file by its _id
export async function download(req, res) {
const _id = req.params.id;
const sql = 'SELECT _id, name, type, data FROM files WHERE _id = $1;';
const { rows } = await db.query(sql, [_id]);
const file = rows[0];
const fileContents = Buffer.from(file.data, 'base64');
const readStream = new stream.PassThrough();
readStream.end(fileContents);
res.set('Content-disposition', `attachment; filename=${file.name}`);
res.set('Content-Type', file.type);
readStream.pipe(res);
return rows[0];
}
// Deletes a file from the database (admin-only)
export async function destroy(req, res) {
const _id = req.params.id;
const sql = 'DELETE FROM files WHERE _id = $1;';
await db.query(sql, [_id]);
res.status(204).send({ message: `File ${_id} deleted.`});
}
On the client side, I'm using ng-file-upload with AngularJS.
Here's the relevant part of the view (in pug for brevity)...
.form-group.col-md-6
label(for='photo') Teacher photo
input.form-control(ngf-select='$ctrl.uploadPhoto($file)', type='file', id='photo', name='photo', ng-model='$ctrl.user.photo', ngf-pattern="'image/*'", ngf-accept="'image/*'", ngf-max-size='100KB', ngf-min-height='276', ngf-max-height='276', ngf-min-width='236', ngf-max-width='236', ngf-resize='{width: 236, height: 276}', ngf-model-invalid='errorFile')
ng-messages.help-block.has-error(for='form.photo.$error', ng-show='form.photo.$dirty || form.$submitted', role='alert')
ng-message(when='maxSize') Please select a photo that is less than 100K.
ng-message(when='minHeight,maxHeight,minWidth,maxWidth') The image must be 236 x 276 pixels.
span(ng-if='$ctrl.user.imageId')
img(ng-src='/api/file/{{ $ctrl.user.imageId }}' alt="Photo of Teacher")
and method in its controller...
uploadPhoto(file) {
if(file) {
this.uploadService.upload({
url: '/api/file/upload',
data: { file }
})
.then(response => {
this.user.imageId = response.data.id;
}, response => {
if(response.status > 0) console.log(`${response.status}: ${response.data}`);
}, evt => {
// Math.min is to fix IE which reports 200% sometimes
this.uploadProgress = Math.min(100, parseInt(100.0 * evt.loaded / evt.total, 10));
});
}
}
I pretty sure this question was asked many items, however I cannot find an answer to my particular problem, which seems very but I just can't seem to get it working. I have a user model with cart schema array embedded in it. I am trying to add an object to an array and if it exists only update quantity and price, if it is doesn't add to an array. what happens with my code is that it adds a new item when array is empty, it updates the item's quantity and price but it doesn't want to add a new item. I read a bit a bout and as far as I understood I cannot use two different db methods in one request. I would appreciate any help on this, this is the first time I am actually using mongooose.
const CartItem = require('../models/cartModel');
const User = require('../models/userModel');
exports.addToCart = (req, res) => {
const cartItem = new CartItem.model(req.body);
const user = new User.model();
User.model
.findById(req.params.id)
.exec((err, docs) => {
if (err) res.sendStatus(404);
let cart = docs.cart;
if (cart.length == 0) {
docs.cart.push(cartItem);
}
let cart = docs.cart;
let isInCart = cart.filter((item) => {
console.log(item._id, req.body._id);
if (item._id == req.body._id) {
item.quantity += req.body.quantity;
item.price += req.body.price;
return true;
}
});
if (isInCart) {
console.log(cart.length)
} else {
cart.push(cartItem);
console.log(false);
}
docs.save(function (err, docs) {
if (err) return (err);
res.json(docs);
});
});
};
I actually managed to get it working like this
exports.addToCart = (req, res) => {
const cartItem = new Cart.model(req.body);
const user = new User.model();
User.model
.findById(req.params.id)
.exec((err, docs) => {
if (err) res.sendStatus(404);
let cart = docs.cart;
let isInCart = cart.some((item) => {
console.log(item._id, req.body._id);
if (item._id == req.body._id) {
item.quantity += req.body.quantity;
item.price += req.body.price;
return true;
}
});
if (!isInCart) {
console.log(cart.length)
cart.push(cartItem);
}
if (cart.length == 0) {
cart.push(cartItem);
}
docs.save(function (err, docs) {
if (err) return (err);
res.json(docs);
});
});
};
don't know if this is the right way to do it, but I can both add a new product into my array and update values of existing ones
Maybe your problem hava a simpler solution: check this page at the mongoose documentation: there is a compatibility issue with some versions of mongoDB and mongoose, maybe you need to edit your model code to look like this:
const mongoose = require("mongoose");
const CartSchema = new mongoose.Schema({
//your code here
}, { usePushEach: true });
module.exports = mongoose.model("Cart", CartSchema);
You can find more information here: https://github.com/Automattic/mongoose/issues/5924
Hope it helps.
I have an array (bookedby) in a Mongoose model defined like this:
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var BarSchema = new Schema({
date: {
type: Date,
required: true
},
barid: {
type: String,
required: true
},
bookedby: {
type: [String],
required: true
},
});
module.exports = mongoose.model('Bar', BarSchema);
I update it with following function, called by a nodejs express router:
const Bars = require("../../models/bars");
const { getToday } = require('../../utils');
module.exports = function(req, res) {
const { barid } = req.body;
const { username } = req.user;
const date = getToday();
if( !barid ) return res.json({ success: false, error: 'Please specify parameter \'barid\'.'})
Bars.findOne({ barid, date }, function (err, bar) {
if (err) return next(err);
if (!bar || bar.bookedby.indexOf(username) === -1) return res.json({ error: `Bar is not booked yet.` });
// Someone booked the bar
const index = bar.bookedby.indexOf(username);
bar.bookedby.splice(index, 1);
bar.save(err => {
if (err) res.json({ error: `Error saving booking.` });
else res.json({ success: true });
});
});
};
Everything works fine, except when I remove the last item from the bookedby array. Then the save() function doesn't update the database. The last item remains there. I guess it has something to do with mongodb optimizing empty arrays, but how can I solve this?
According to the Mongoose FAQ:
http://mongoosejs.com/docs/faq.html
For version >= 3.2.0 you should use the array.set() syntax:
doc.array.set(3, 'changed');
doc.save();
If you are running a version less than 3.2.0, you must mark the array modified before saving:
doc.array[3] = 'changed';
doc.markModified('array');
doc.save();
