I am getting all the order details
For example:(example of one order)
{
"customer": {
"id": "5db6ac89d85a2c1c709a42da",
"name": "Testing"
},
"product": {
"id": "5dba78427af9e73b18bdbb22",
"name": "image",
"seller": "Testing",
"price": 100,
"imgurl": "ok"
},
"_id": "5dba788fdeb78931f8a30105",
"quantity": 3
}
When I use find() I get all the elements but I only want to show the data of the one who is logged in
i.e where customer.id equals to req.user._id
I am using find() as shown in the code below:
router.get('/cart',verifyToken, async (req, res)=>{
const order = await Order.find({/* what should be the query here to get the desired result*/},'product , quantity , customer ');
try{
res.send(order)
}catch(err){
res.status(400).send(err);
}});
Any other methods to achieve this
You have to use findOne().Like below
const order = await Order.findOne({'customer.id':req.user._id}) // probably req.body.user._id
or
await Order.findOne( { customer: { id:req.user._id } } )
See the docs here

This is my user object sent as token in req:
{
"_id": "6212aba16653621e67393549c",
"name": "User",
"email": "user#gmail.com",
"__v": 0
}
This is my get function code:
const getSharedLists = asyncHandler(async (req, res) => {
const lists = await List.find({
sharedWith: { email: req.user.email },
});
res.status(200).json(lists);
});
This is what object looks like:
{
"_id": "621817233300dfff68e23710",
"user": "6212ab33383621e67393549c",
"listName": "test update",
"private": true,
"items": [
{
"itemName": "Bananas",
"quantity": 3,
"isBought": false,
"isle": "isle",
"_id": "621b043622147906eece2e72"
},
],
"sharedWith": [
{
"email": "user#gmail.com",
"_id": "621bdbf0791a322534284c49"
}
],
"createdAt": "2022-02-24T23:39:25.668Z",
"updatedAt": "2022-02-27T21:21:03.584Z",
"__v": 0,
},
I keep getting empty array back, even when hard code req.user.email as "user#gmail.com" for example. I need to find all lists on MongoDb that have my email in array of sharedWith.
Can somebody help please. Apparently I'm using List.find method wrong but can't seem to figure out the syntax.
You need (.) dot notation.
const lists = await List.find({
"sharedWith.email" : req.user.email
});

Reference
Specify a Query Condition on a Field Embedded in an Array of Documents
I am writing REST API in NodeJS with MongoDB. Structure of the database is:
[
{
"_id": "12345",
"name": "Meal name",
"category": "dessert",
"area": "british",
"imageUrl": "https.image.jpg",
"instructions": "some instructions...",
"ingredients": [
{
"name": "salt",
"measure": "1g"
},
{
"name": "chicken",
"measure": "1"
},
{
"name": "butter",
"measure": "90g"
}, ...
]
}, ...
]
I can write a route to get data which meet one condition,
i.e.:
//getting all, when category = :category
router.get('/meals/category=:category', async (req, res) => {
try {
const meals = await Meal.find({category: req.params.category})
res.json(meals)
} catch (err) {
res.status(500).json({ message: err.message })
}
})
Here, route
'meals/category=vegetarian'
get all data with category = vegetarian.
However, I want to have route, which will filter all data by parameters: category, area, ingredients.
For example:
meals/ingredients=salt,pepper&category=dessert&area=american
should return all data, which contains salt and pepper in array, and category = dessert.
another example:
meals/area=american&category=dessert
should return all data, where area=american and category=dessert
How can I write the router.get() method to achieve that?
I'm trying to update a value inside mogoodb array but is the problem
database?
"TempChannels": [{
"user": "299481590445113345",
"channel": "794869948878159884",
"settings": []
}, {
"user": "583363766750806043",
"channel": "795004103998308352",
"settings": []
}],
The part of the code that should update the user:
Data.TempChannels[0].user = Target.id
Data.save().catch(er => console.log(er))
Also, no error appears when I run the code. and when i console the data it returns a user which has updated but it is not actually saved in mongodb!
code
Data.save().then(() => console.log(Data.TempChannels[0].user))
this is the whole data
{
"_id": {
"$oid": "5ff0cd1ee3d9fd2d40d82d23"
},
"TempChannels": [{
"user": "299481590445113345",
"channel": "795014692522295326",
"settings": []
}, {
"user": "583363766750806043",
"channel": "795015273060892753",
"settings": []
}],
"Guild": "704158258201624657",
"Stats": "true",

"DefaultSettings": {
"limit": null,
"name": null,
"bitrate": null,
"copyperms": null
},
"__v": 2
}
I'm filtering the data by Guild
if you are using mongoose to connect MongoDB, the
Use markModified("updated field name")
Data.TempChannels[0].user = Target.id
Data.markModified('TempChannels');
Data.save().catch(er => console.log(er))
if you are using mongoose, there is a method that will allow to update the content of existing data
const res = await Person.replaceOne({ _id: 24601 }, { name: 'Jean Valjean' });
res.n; // Number of documents matched
res.nModified; // Number of documents modified
If you are using Mongoose, you can update the record by doing something similar to this:
SchemaName.update({Guild: 'Guild Value Here'}, {$set: { "TempChannels[0].user" : "%newvalue%"}})
.then((data) => {
console.log(data)
})
.catch(err => {
console.log.error(err);
});
You should replace schemaName with the name of your schema if you are using mongoose, and in case you are not using it, I think it would be better for you to start using it.
I have the following Board object:
{
"boardMembers": [
"5f636a5c0d6fa84be48cc19d"
],
"boardLists": [
{
"cards": [],
"_id": "5f6387e077beba2e3c15d15a",
"title": "list one",
"__v": 0
}
],
"_id": "5f63877177beba2e3c15d159",
"boardName": "board1",
"boardPassword": "123456",
"boardCreator": "5f636a5c0d6fa84be48cc19d",
"g_createdAt": "2020-09-17T15:57:37.616Z",
"__v": 2
}
as you can see there is a "boardLists" array, I want to make a post request that post a card to a list inside that array with specific ID.
that my code:
router.post("/add-task/:id", auth, boardAuth, async (req, res) => {
const listId = req.params.id;
try {
const board = await Board.findOne({ _id: req.board._id });
if (!board) return res.status(404).send("no such board");
const list = await List.findOne({ _id: listId });
if (!list) return res.status(404).send("List not found");
const task = new Task({
text: req.body.text,
});
Board.updateOne(
{ _id: req.board._id, "boardLists._id": listId },
{ $push: { "boardLists.$.cards": task } }
);
await board.save();
res.send(board);
} catch (err) {
console.log(err);
}
});
Now the problem is when I make the request call in postman its does the push inside the specific list that i want but its not saving the push inside the parent board object: when do a get request to that object i get an empty cards array.
like that:
{
"boardMembers": [
"5f636a5c0d6fa84be48cc19d"
],
"boardLists": [
{
"cards": [],
"_id": "5f6387e077beba2e3c15d15a",
"title": "list one",
"__v": 0
}
],
"_id": "5f63877177beba2e3c15d159",
"boardName": "board1",
"boardPassword": "123456",
"boardCreator": "5f636a5c0d6fa84be48cc19d",
"g_createdAt": "2020-09-17T15:57:37.616Z",
"__v": 2
}
Why its not saving the push in the board object?
Mongoose is weird. You need to mark the field as modified, otherwise the changes won't be saved. Try this :
board.markModified("boardLists");
await board.save();
In my Node API and MongoDB, I'm trying to build an endpoint to search for data in the DB and get back the results to the client. My search goal is to show results from the Profile collection and in that way, I can build my queries to search by first name, surname, company and the combination of it as an example:
GET search?fn=joe or ?ln=doe or ?cp=Company or ?fn=...&ln=...&cp=...
Practically I can search in different ways and I can get for example all the people working for a company as a result of a search.
I would like to understand how can I achieve that with Mongoose/MongoDB and add also to the query optional a limit/pagination for the coming results.
I tried to make some simple trials but I got stuck as I do not really get it how to proceed next.
const SearchController = {
async getQuery(req, res) {
try {
const { fn, ln, cp } = req.query;
const searchResult = await Profile.find({
$or: [
{ firstname: fn },
{ surname: ln },
{
experience: {
company: cp
}
}
]
});
res.status(200).json(searchResult);
} catch (err) {
res.status(500).json({ message: err.message });
}
}
};
The JSON of a profile:

The expected results are for example if I search the first name Joe I should get back all the profiles having as first name Joe. Similar for surname and company.
Please provide comments to allow me to understand if you need more scripts from the original code to see.
EDITED added the code modified of the search
// Models
const { Profile } = require("../models");
// Error handling
const { ErrorHandlers } = require("../utilities");
const SearchController = {
async getQuery(req, res) {
try {
const { fn, ln, cp } = req.query;
const query = {
$or: []
};
if (fn) query.$or.push({ firstname: fn });
if (ln) query.$or.push({ surname: ln });
if (cp) query.$or.push({ "experience.company": cp });
const searchResult = Profile.find(query, docs => {
return docs
});
if ((await searchResult).length === 0)
throw new ErrorHandlers.ErrorHandler(
404,
"Query do not provided any result"
);
res.status(200).json(searchResult);
} catch (err) {
res.status(500).json({ message: err.message });
}
}
};
module.exports = SearchController;
Have tried conditional query and modified your array search query for finding the company,
function findUser(fn, ln, cp) {
const query = {
$or: []
}
if (fn) query.$or.push({ firstname: fn })
if (ln) query.$or.push({ surname: ln })
if (cp) query.$or.push({ "experience.company": cp })
Profile.find(query, function (err, docs) {
if (err) {
console.error(err);
} else {
console.log(docs);
}
});
}
findUser("","","IBM")
