I have a mongo schema like this.
{
userID:19202,
products:[ { id:020, name:'first' }]
}
I want to pop items from the product array based on id. I used the following command. although it didn't give any error, it also not deleting elements from an array.
userCart.updateOne(
{ userID:userID},
{ $pull: { products: { id:id } } }
)
.then((data) =>
{
if(data)
{
//data is {
"n": 1,
"nModified": 0,
"ok": 1
}
return res.json({
status:true,
message:"cart updated"
})
}
})
Demo - https://mongoplayground.net/p/mh6fXN21vyR
Make sure id and products.id are of the same type as in your document in the database. As your sample, both should be numbers.
if they both are number
db.collection.update({
userID: 19202
},
{
$pull: {
"products": { id: 20 }
}
})
Not Working here - https://mongoplayground.net/p/3zhv8yoH2o9 when "products": { id: "20" }. products.id is a string in the mongo query and in the database in number so mismatched.
Try this one:
db.userCart.update(
{ userID:userID },
{ $pull: { items: { id: 020 } } },
false, // Upsert
true, // Multi
);

How do I push to the inner arrays in MongoDB?
[
{ emoji1: ['user19', 'user20', 'user21']},
{ emoji5: ['user12', 'user13', 'user14']},
{ emoji9: ['user29', 'user30', 'user34']}
]
I tried:
await Post
.updateOne({ _id: postID }, {
$push: {
[`reactions[0].emoji1`]: 'random user'
}
})
...where Post is my Mongoose Schema and "reactions" is the array above. I think I am doing something wrong in $push.
The result should be:
[
{ emoji1: ['user19', 'user20', 'user21', 'random user']},
{ emoji5: ['user12', 'user13', 'user14']},
{ emoji9: ['user29', 'user30', 'user34']}
]
You can use this query:
db.collection.update({
id: 1,
"reactions.emoji1": {
"$exists": true
}
},
{
"$push": {
"reactions.$.emoji1": "random user"
}
})
Example here
I have array of strings like this
let fromHour = ['2.5','3','3.5']
let toHour = ['2.5','3','3.5']
I have an array of object saved in mongoDB
timeRange = [
{
from:'2.5',
to:'3'
},
{
from:'3',
to:'3.5'
}
]
I want to check if any of my array of string value exist in that object value
I have tried this but it give me this error ( Unrecognized expression '$match' )
checkAppoint = await Appointment.aggregate([
{
$project: {
date: myScheduleFinal[k].date,
status: { $in: ['pending', 'on-going'] },
timeRange: {
'$match': {
'from': { $in: fromHolder },
'to': { $in: toHolder },
},
},
},
},
]);
also I have tried this solution and it work for me but it take to much time so I am trying this with aggregate
checkAppoint = await Appointment.findOne({
date: myScheduleFinal[k].date,
status: { $in: ['pending', 'on-going'] },
timeRange:{$elemMatch:{
from:{$in:fromHolder},
to:{$in:toHolder}
}}
});
So anyone have a solution for that
Just try $elemMatch and $in operators,
using find() method
checkAppoint = await Appointment.find({
timeRange: {
$elemMatch: {
from: { $in: fromHour },
to: { $in: toHour }
}
}
})
Playground
using aggregate() method
checkAppoint = await Appointment.aggregate([
{
$match: {
timeRange: {
$elemMatch: {
from: { $in: fromHour },
to: { $in: toHour }
}
}
}
}
])
Playground
So I have found a way around to solve this problem and I will share the solution I used
First I want to minimize my request to mongodb so I am now making just one request that bring all the appointment with the required date
and I want to make it this way because my fromHour and toHour array will change many time through single request
helperArray => contains all the day I want to check it's range
let checkAppoint = await Appointment.find({
date: { $in: helperArray },
status: { $in: ['pending', 'on-going'] },
});
now inside my for loop I will go through that data
checkAppoint.filter((singleAppoint) => {
if (singleAppoint._doc.date === myScheduleFinal[k].date) {
singleAppoint._doc.timeRange.map((singleTime) => {
if (fromHolder.includes(singleTime.from)) {
busy = true;
}
});
}
});
I want to rename the path of the fields which are coming from the response.
My Query:
const allLeads = await Lead.find().select({
"basic.mobileNumber": 1
});
res.send({ allLeads });
Response I'm Getting
{
"allLeads": [
{
"_id": "5d9f0e2118d1a445bae077aa",
"basic": {
"mobileNumber": "1223654789"
}
},
{
"_id": "5d9f16a8cba7744902acb422",
"basic": {
"mobileNumber": "1123654789"
}
}
]
}
how I want the response
{
_id: 5d9f0e2118d1a445bae077aa,
mobileNumber: "1223654789"
},
{
_id: 5d9f16a8cba7744902acb422,
mobileNumber: "1123654789"
}
So is there any way yo archive this using mongoose?
I did it like this. Is there any other and better way to do this?
let simpleLeadInfo = [];
await SwatiLead.find()
.select({
_id: 1,
"basic.mobileNumber": 1,
})
.exec((err, data) => {
if (!err) {
for (lead in data) {
const obj = {
id: data[lead]._id,
mobileNumber: data[lead].basic.mobileNumber,
};
simpleLeadInfo = [...simpleLeadInfo, obj];
}
return res.send({ error: false, status: "OK", simpleLeadInfo });
}
});
I want to do all the find the data from the collection and then want to update some field as well as depending on want to empty the array.
const addCityFilter = (req, res) => {
if (req.body.aCities === "") {
res.status(409).jsonp({ message: adminMessages.err_fill_val_properly });
return false;
} else {
var Cities = req.body.aCities.split(","); // It will make array of Cities
const filterType = { "geoGraphicalFilter.filterType": "cities", "geoGraphicalFilter.countries": [], "geoGraphicalFilter.aCoordinates": [] };
/** While using $addToset it ensure that to not add Duplicate Value
* $each will add all values in array
*/
huntingModel
.update(
{
_id: req.body.id,
},
{
$addToSet: {
"geoGraphicalFilter.cities": { $each: Cities }
}
},
{$set:{filterType}},
).then(function(data) {
res.status(200).jsonp({
message: adminMessages.succ_cityFilter_added
});
});
}
};
Collection
geoGraphicalFilter: {
filterType: {
type:String,
enum: ["countries", "cities", "polygons"],
default: "countries"
},
countries: { type: Array },
cities: { type: Array },
aCoordinates: [
{
polygons: { type: Array }
}
]
}
But as result, the only city array is getting an update. No changes in filterType.
You appear to be passing the $set of filterType as the options argument, not the update argument.
huntingModel
.update(
{
_id: req.body.id,
},
{
$addToSet: {
"geoGraphicalFilter.cities": { $each: Cities }
},
$set: {
filterType
}
}
).then(function(data) {
res.status(200).jsonp({
message: adminMessages.succ_cityFilter_added
});
});
