I'm trying to add blockDate into user db, but the code below doesn't make any changes. I checked out that data.username and blockDate are valid value. I get { ok: 0, n: 0, nModified: 0 } from res variable. how can I figure out what is wrong with this request?
router.post('/account/block', async (ctx, next) => {
let data = ctx.request.body
let fixedDate = parseInt(data.days)
let blockDate = DateTime.local().plus({days: fixedDate}).toISO()
let param = {
search: { username: data.username},
update: { $set: {blockDate: blockDate}}
}
try {
console.log(param)
let res = await User.update(param.search, param.update, {multi: true})
console.log("res", res)
} catch (e) {
console.log("err", e)
}
})
I can't tell you if it is supposed to be a date at all without seeing your mongoose model.
If it has the type Date your mongoose validator is probably going to filter it which could be the reason that no update is happening. You could use moment for converting the string to a date. For instance (including a few other "improvements" which you may like or not):
router.post('/account/block', async (ctx, next) => {
const data = ctx.request.body
const fixedDate = parseInt(data.days)
const blockDateString = DateTime.local().plus({days: fixedDate}).toISO()
const blockDate = moment(blockDateString)
const param = {
search: { username: data.username},
update: { blockDate }
}
try {
console.log(param)
const res = await User.update(param.search, param.update, {multi: true})
console.log("res", res)
} catch (e) {
console.log("err", e)
}
})

I'm trying to create a user after he verified the code that I send him
so first I generate the code in sendCode resolver and save it in Redis using setex
the problem is that code is set in Redis but when I try to use it in createUser resolver using get it returns null.
const sendCode: MutationResolvers["sendCode"] = async ({
input: { phoneNumber, email },
}: {
input: SendCodeInput;
}) => {
const code = generate4digitNum();
await redis.setex(phoneNumber ?? email, THREE_MINS, code);
return {};
};
const createUser: MutationResolvers["createUser"] = async ({
input: { ...userData },
}: {
input: CreateUserInput;
}) => {
const code = await redis.get(userData.phoneNumber ?? userData.email);
if (code !== userData.code) {
throw new Error(errors[0].id);
}
user = await userModel.create({ ...userData});
return {type: user.type, _id: user._id };
};
the redis.ts file that I create:
const client = redis.createClient({
host: process.env.REDIS_HOST,
password: process.env.REDIS_PASSWORD,
port: Number(process.env.REDIS_PORT),
});
client
.on("connect", function () {
console.log(`connected ${client.connected}`);
})
.on("error", function (error) {
console.log(error);
});
export const get: (key: string) => Promise<string> = promisify(client.get).bind(
client
);
export const setex: (
key: string,
seconds: number,
value: string
) => Promise<string> = promisify(client.setex).bind(client);
I will appreciate any kind of help.
Thanks in advance.
I'm trying to make a "edit" feature for my project, and I'm stuck at this part..
I have a put request :
export const updateEvent = (event, id) => (dispatch, getState) => {
request
.put(`${baseUrl}/event/${id}`)
.send(event)
.then(response => {
dispatch(updatedEvent(response.body))
})
.catch(error => console.log(error))
}
This is the route for the said put, with Sequelize as ORM:
router.put('/event/:id', async (req, res, next) => {
const { id } = req.params
try {
const event = await Event.findByPk(id)
const updatedEvent = await event.update(req.body)
res.send(updatedEvent)
} catch (error) {
next(error)
}
})
When I test it with postman, everything works as expected. Where I ran into my problem is when I'm sending the put data from React in the frontend.
I have a form, and I save my data in the local state, and then dispatch it to actions like this:
handleSubmit = e => {
e.preventDefault()
const id = this.props.event.id
const updatedEvent = {
name: this.state.name,
description: this.state.description,
picture: this.state.picture,
startDate: this.state.startDate,
endDate: this.state.endDate,
userId: this.props.userId
}
this.props.updateEvent(updatedEvent, id)
}
Any value that is left empty in the form is overwriting my fields with nothing (an empty string). How do I properly handle this?
A solution is to filter your object, such that you remove any properties which have empty values and therefore won't be included in the database update.
In your router.put():
router.put('/event/:id', async (req, res, next) => {
const { id } = req.params
try {
const event = await Event.findByPk(id);
// filter req.body to remove empty values
const { body } = req;
const filteredBody = Object.keys(body).reduce((resultObj, key) => {
if(body[key] != ''){
resultObj[key] = body[key];
}
return resultObj;
}, {});
const updatedEvent = await event.update(filteredBody);
res.send(updatedEvent)
} catch (error) {
next(error)
}
})
What would be the best approach to only POST data into MongoDB if it doesn't exist in the table? hash would be the unique field for searching, this field is also indexed.
router.post('/', async (req, res) => {
try{
var id = null
const keywords = await db.dbConn('kw_data');
await keywords.insertOne({
result: req.body,
added: new Date(),
modified: new Date(),
hash: req.body.hash
}).then(resp => {
id = resp.insertedId
})
var data = {}
data = await keywords.findOne({_id: id});
res.status(201).send(data);
}
catch(e) {
res.status(400).send(e);
res.status(404).send(e);
res.status(500).send(e);
}
})
You can use
await keywords.update(
<query>,
<update>,
{
upsert: <boolean>,
}
);
and set
upsert:true
So you are inserting data and database will itself know if data is created it will get updated and if it does not exist the database will create it for you
I think I have got it by just doing a check on the hash, but not sure if this is the best approach, correct me if I'm wrong...
router.post('/sug', async (req, res) => {
try{
var id = null
const keywords = await db.dbConn('kw_sug');
check = await keywords.findOne({hash: req.body.hash});
if(check === null){
await keywords.insertOne({
results: req.body,
added: new Date(),
modified: new Date(),
hash: req.body.hash
}).then(resp => {
id = resp.insertedId
})
var data = {}
data = await keywords.findOne({_id: id});
res.status(201).send(data);
}else{
res.status(201).send('duplicated');
}
}
catch(e) {
res.status(400).send(e);
res.status(404).send(e);
res.status(500).send(e);
}
})
how do I post to referenced schemas in mongodb while using async-await. i was able to create the get function but i am having a hard time creating the post and the put.
here is my get function :
I think, in your request body you should only pass issue id and user id. So when you get the task with your get task details API, mongoose will prepopulate the data.
Your request body should look like
{
issue: "5ca2b1f80c2e9a13fcd5b913",
user: "5ca2b1f80c2e9a13fcd5b90b",
record: {
votary: 80,
development: 90,
test: 100
},
date: "2019-03-01T15:00:00.000Z"
};
And then save the task details as
try {
const task = new TaskModel(req.body);
const result= await task.save()
return api.responseJSON(res, 200, result);
} catch (e)
{
// Error
}
Just wrap the code inside of post in a try/catch
export const post: Operation = async (req: express.Request, res: express.Response) => {
try {
const param: any = {};
const task = new TaskModel(req.body);
const newTask = await task.save()
return api.responseJSON(res, 200, newTask);
} catch(err) {
// treat error
}
}
You should not save the complete req.body instead save only those fields which your schema accepts. And according to Task schema issue and user fields should store id but not the complete object which is there in req.body. Please try this and update your post method accordingly:
export const post: Operation = async (req: express.Request, res: express.Response) => {
try {
let param: any = {};
const user = {
id: req.body.user.id
};
const issue = {
id: req.body.issue.id
};
param = req.body;
param.user = user.id
param.issue = issue.id
const task = new TaskModel(param);
const newTask = await task.save()
return api.responseJSON(res, 200, newTask);
} catch (e) {
api.responseJSON(res, 400, e)
}
};
I listen to the chat event of the tmijs library, upon the !overlay chat I want to execute some code. What I want to achieve upon getting that message is:
Fetch the user
Check if the user has enough currency
Deduct currency from the user
Trigger a socket event to my react app
Everything seems to work up until the last bullet point. In my terminal it's shown that my user gets currency (called 'kluiten' in my code) deducted, but all the code that comes after it doesn't get executed.
require('dotenv').config();
const PORT = process.env.PORT || 9000;
class TwitchAPI {
constructor({io}) {
this.io = io;
this.client = new tmi.client(options);
this.client.connect();
this.handleOverlayRequest = this.handleOverlayRequest.bind(this);
this.handleChatMessage = this.handleChatMessage.bind(this);
this.client.on('chat', this.handleChatMessage);
}
handleChatMessage (channel, userstate, message) {
if(message === '!overlay') this.handleOverlayRequest(channel, userstate);
}
async handleOverlayRequest (channel, userstate) {
const requiredKluiten = 5;
const rawFoundUser = await fetch(`http://localhost:${PORT}/api/users/${userstate.username}`);
const foundUser = await rawFoundUser.json();
if(foundUser.instakluiten >= requiredKluiten) {
this.client.action(channel, `${userstate[`display-name`]}, you've got enough instakluiten for this.`);
const method = `PUT`;
const payload = { 'requiredKluiten': requiredKluiten };
const body = JSON.stringify(payload);
const headers = { 'Content-Type': `application/json; charset=utf-8` };
const result = await fetch(`http://localhost:${PORT}/api/users/${userstate.username}/decrementKluiten`, { method, body, headers });
console.log(result);
}
}
}
module.exports = TwitchAPI;
I then have an Express router:
const express = require('express');
const userController = require('../controllers/userController');
const router = express.Router();
router.route('/users/:username/decrementKluiten').put(userController.decrementKluiten);
router.route('/users/:username').get(userController.getUser);
router.route('/overview').get(userController.getOverview);
module.exports = router;
which makes sure the currency gets deducted. What I'm stuck on now is that, after all this has happened, I can't execute any code anymore after the fetch. I found though that I could execute code by resolving the promise in my route, but that feels really dirty and messes up my split up files:
router.route('/users/:username/decrementKluiten').put((req, res) => {
userController.decrementKluiten(req, res).then(x => {
console.log(x);
});
});
Is there a way to wait for my PUT to happen and still execute code after it did?
EDIT
userController.js
const {findChattersPerRole, getUserByUsername, decrementKluiten} = require('../actions');
const find = require(`lodash/find`);
const fetch = require(`isomorphic-fetch`);
const parseJSON = response => response.json();
module.exports = {
getUser: (req, res) => {
const username = req.params.username;
findChattersPerRole()
.then(chattersPerRole => {
const wantedUser = find(chattersPerRole, { username });
getUserByUsername(wantedUser.username)
.then(foundUser => {
if (foundUser) {
res.send(foundUser);
} else {
res.send(`No user has been found`);
}
});
});
},
getOverview: (req, res) => {
fetch(`https://tmi.twitch.tv/group/user/instak/chatters`)
.then(parseJSON)
.then(r => {
return res.json(r);
}).catch(err => {
console.log(err);
});
},
decrementKluiten: (req, res) => {
decrementKluiten(req.params.username, req.body.requiredKluiten);
}
}
actions.js
(Because this contains a lot of code I try to only include the relevant parts for this post, the database calls are done using Sequelize.js)
const decrementKluiten = (username, requiredKluiten) => {
return global.db.Viewer.findOne({
where: { username }
}).then(user => {
return user.decrement({ instakluiten: requiredKluiten });
});
};
module.exports = {
decrementKluiten
};
The issue is likely that you don't respond to the HTTP request in your /users/:username/decrementKluiten route. To solve this, change the exported decrementKluiten method in userController.js-file to this:
decrementKluiten: (req, res) => {
decrementKluiten(req.params.username, req.body.requiredKluiten)
.then(() => res.sendStatus(200))
.catch(() => res.sendStatus(500));
}
Some unrelated pointers to make your code a bit more readable, since you already use async functions in some parts of your code, but in other parts you interface directly with Promises.
The exported part of userController.js could utilize async functions:
module.exports = {
getUser: async (req, res) => {
try {
const username = req.params.username;
let chattersPerRole = await findChattersPerRole();
let wantedUser = find(chattersPerRole, { username });
let foundUser = await getUserByUsername(watnerUser.username);
if (foundUser) {
res.status(200).send(foundUser);
} else {
res.status(404).send('No user has been found');
}
} catch (e) {
res.sendStatus(500);
}
},
getOverview: async (req, res) => {
try {
let r = (await fetch('https://tmi.twitch.tv/group/user/instak/chatters')).json();
res.json(r);
} catch (e) {
res.sendStatus(500);
}
},
decrementKluiten: async (req, res) => {
try {
await decrementKluiten(req.params.username, req.body.requiredKluiten);
res.sendStatus(200);
} catch (e) {
res.sendStatus(500);
}
}
}
I've also added error handling in case something goes wrong, the server responds with a 500 Internal Server Error status code.
Judging by these lines in your TwitchAPI class:
const rawFoundUser = await fetch(`http://localhost:${PORT}/api/users/${userstate.username}`);
const foundUser = await rawFoundUser.json();
I assume you've tried to do const foundUser = await fetch('...').json(). This results in an error, but you can call the retuned value's methods and properties on the same line if you wrap the await expression in parentheses, like this:
const foundUser = await (await fetch('...')).json()`
If its methods does not return a Promise (i.e being synchronous), or you want to access a property, you can do:
const something = (await doSomethingAsync()).someMethod()
const somethingElse = (await doSomethingAsync()).property
I also noticed you're using template literals (backticks, `) for most strings without doing any template interpolation, which could simply be replaced with ' (single-quotes) or " (double-quotes).
