I'm trying to update an array of id's instead of just one id but with no succes. I'm not even sure on how the payload data should look like.
This is my current request payload:
query: "mutation {
addStudentToGroup(
id: " [5c3b9884277bbd61dcdc174b,5c3b9884277bbd61dcdc174c]",
groupId: "5c3b974157905b2808373e3c"
)
{ id }
} "
And in my GraphQL I did this:
addStudentToGroup: {
type: StudentType,
args: {
id: {type: GraphQLList(GraphQLID)},
groupId: {type: GraphQLID}
},
resolve(parent, args) {
return Student.updateMany(
{ id: { $in: args.id} },
{ $set: { groupId: args.groupId }}
);
}
},
But what it returns to me is:
{"data":{"addStudentToGroup":{"id":null}}}
Why is this not working? It does work when I use findByIdAndUpdate

I am using findOneAndUpdate, where I want
to return updated document
i dont want to return the entire document but only the following:
one object out of an array + a virtual property in the document.
const notifications = {
to:
messages: [
{_id: "23452", title:"hello"}, {_id: "23452", title:"bye"}
]
...
}
so for example I would want to only return the object {_id: "23452", title:"bye"} AND unreadCount virtual field prop.
my code works so far as I am returning updated document and only the message I want, but I dont know how to return also the unreadCount prop.
schema:
const notificationSchema = new mongoose.Schema({
to: {
type: mongoose.Schema.Types.ObjectId,
ref: 'User'
},
messages: [{
title: {
type: String,
required: true
},
isRead: {
type: Boolean,
default: false
},
createdAt: {
type: Date,
default: new Date()
}
}, ]
},
{timestamps: true, toObject: {virtuals: true}
});
notificationSchema.virtual('unreadCount').get(function() {
... return count;...
})
updateRead: async (userId, id) => {
const notification = await Notification.findOneAndUpdate({to: userId, 'messages._id': id}, {
$set: { "messages.$.isRead": true} },
{ select: {
messages: {
$elemMatch: {_id: id}
}
}, new: true});
}
My code on the backend, in case it matters (NodeJS and MogoDB):
//my includes at the top of the file
const mongoose = require('mongoose');
const Appt = mongoose.model('Appt');
const ApptType = mongoose.model('ApptType');
const ApptStatus = mongoose.model('ApptStatus');
var moment = require('moment-timezone');
moment().tz('America/New_York');
now = moment(); // add this 2 of 4
dayStart = now.startOf('day');
dayEnd = now.endOf('day');
// the aggregation query that's not returning correctly
Appt.aggregate([
{
$match: {
patientID: appt.patientID._id,
scheduled: {
$gte: new Date(start),
$lt: new Date(appt.pmtduedate)
}
}
},
{
$group: {
_id: 'id',
payment: { $sum: '$payment' },
pmtdue: { $sum: '$pmtdue' },
visits: { $sum: 1 }
}
}
]).exec(
err => {
console.log(`Error finding past payments`, err);
callback(err);
},
result => {
console.log(`RESULT: ${result}`);
pastPayments = result;
if (!pastPayments || pastdueamt === 0) {
pastdueamt = 0;
console.log(`2. getCurrentDue ${pastdueamt}`);
this.getCurrentDue(appt, pastdueamt, today, callback);
} else {
console.log(`pastPayments ${pastPayments}`);
console.log(
`planamt ${planamt} pmtdue ${pastPayments.pmtdue} payments: ${pastPayments.payment}`
);
pastdueamt =
pastPayments.pmtdue === 0
? planamt - pastPayments.payment
: pastPayments.pmtdue - pastPayments.payment;
console.log(`pastdueamt calculated: ${pastdueamt}`);
console.log(`2. getCurrentDue`);
this.getCurrentDue(appt, pastdueamt, today, callback);
}
}
);
When I run my query in mongo, the expected results return. In my app, the results of this query above return nothing (no error, either). I've tried doing the following:
$match: {
patientID: new mongoose.types.ObjectId(appt.patientID._id),
I've also tried:
$match: {
patientID: { $toObjectId: appt.patientID._id },
but I get errors on both of these options. The first returns an error of
TypeError: Cannot read property 'ObjectId' of undefined.
The second returns some sort of mongo error
errmsg: 'unknown operator: $toObjectId',
code: 2,
codeName: 'BadValue',
name: 'MongoError',
[Symbol(mongoErrorContextSymbol)]: {} }
How do I do mongoose aggregation successfully using objectIds, virtual types, etc.?
EDITED TO ADD MY SCHEMAS:
const apptSchema = new mongoose.Schema(
{
ID: Number,
patientID: {
type: mongoose.Schema.Types.ObjectId,
ref: 'Patient'
},
oldPatientID: Number,
status: {
type: mongoose.Schema.Types.ObjectId,
ref: 'ApptStatus'
},
type: {
type: mongoose.Schema.Types.ObjectId,
ref: 'ApptType'
},
scheduled: Date,
note: String,
reminder: Boolean,
cell: Boolean,
email: Boolean,
subjective: String,
assessment: String,
plan: String,
planamt: Number,
objective: {
clearUC: Boolean,
UCcheck: String,
thompson: String,
activator: String,
other: String
},
updated: {
type: Date,
default: new Date()
},
pmtdue: Number,
pmtduedate: Date,
payment: Number,
pmttype: String,
paid: Boolean,
pmtnote: String
},
{ toJSON: { virtuals: true } }
);
Let's say I have this Schema:
const PostSchema = new Schema({
user: {
type: Schema.Types.ObjectId,
ref: 'users'
},
text: {
type: String,
required: true
},
comments: [
{
user: {
type: Schema.Types.ObjectId,
ref: 'users'
},
text: {
type: String,
required: true
},
date: {
type: Date,
default: Date.now
}
}
],
date: {
type: Date,
default: Date.now
}
});
And let's say I save 10 posts to the database. How can I get total length(count) of all comments they have?
This works only for whole collection of Post. It returns 10.
router.get( '/total', ( req, res ) => {
Post.estimatedDocumentCount().then( ( totalCount) => {
res.json( totalCount );
}).catch( ( err ) => {
console.log( err );
});
});
I don't want to use .count() method since it's deprecated.
Thank you
You can use $group and find total counts of comments as below:
db.collection.aggregate([
{
$group: {
_id: null,
count : { $sum: { $size: "$comments"}}
}
}
])
This question already has answers here:
Node.js Mongoose.js string to ObjectId function
(9 answers)
Closed 4 years ago.
I have an array of ids which is launchIds.
I'm trying to push it on a model field trips with
$addToSet: { trips: { $each: launchIds }. This gives me an error: Cast to [ObjectId] failed for value \"[\"1\",\"2\",\"3\"]\...
if I try to map through launchIds and convert to Mongoose.Shema.Types.ObjectId I get in the database trips: [null,null,null]
lauchIds = ['1','2','3']
async bookTrips({ launchIds }) {
let userId = "5bf7f7b3817119363da48403";
const mongoIds = launchIds.map(l => Mongoose.Schema.Types.ObjectId(l));
return this.store.User.findByIdAndUpdate(
{ _id: userId },
{
$addToSet: { trips: { $each: mongoIds } }
},
{ new: true }
);
}
Here's my model Schema:
const UserSchema = new Mongoose.Schema(
{
email: {
type: String,
required: true
},
token: String,
trips: [
{
type: Mongoose.Schema.Types.ObjectId,
ref: "trip"
}
]
},
{ timestamps: true }
);
I'm passing ids via grapql playground. Here's my mutation:
bookTrips: async (_, { launchIds }, { dataSources }) => {
console.log(launchIds);
// logs ['1','2','3']
console.log(typeof launchIds);
//Object
const results = await dataSources.userAPI.bookTrips({ launchIds });
console.log(results);
return { message: "hello" };
}
To convert a string or a number into mongo object use Mongoose.Types.ObjectId,
const mongoIds = launchIds.map(l => Mongoose.Types.ObjectId(l));
I was getting back an array of strings where this should be numbers
The solution:
My model (same as above):
const UserSchema = new Mongoose.Schema(
{
email: {
type: String,
required: true
},
token: String,
trips: [
{
type: Mongoose.Schema.Types.ObjectId,
ref: "trip"
}
]
},
{ timestamps: true }
);
crud API:
async bookTrips({ launchIds }) {
let userId = "5bf7f7b3817119363da48403";
const idsToNums = launchIds.map(Number);
const mongoIds = idsToNums.map(l => Mongoose.Types.ObjectId(l));
return this.store.User.findByIdAndUpdate(
{ _id: userId },
{
$push: { trips: { $each: mongoIds } }
},
{ new: true }
);
}
Notice the Mongoose.Schema.Types.ObjectId on model and Mongoose.Types.ObjectId on api. If I remove Schema from model or add Schema to api I'm getting an error. Not sure why, but the above example works. I hope someone will find this helpful or suggests a better solution.
i'm trying to do a pretty simple operation, pull an item from an array with Mongoose on a Mongo database like so:
User.update({ _id: fromUserId }, { $pull: { linkedUsers: [idToDelete] } });
fromUserId & idToDelete are both Objects Ids.
The schema for Users goes like this:
var UserSchema = new Schema({
groups: [],
linkedUsers: [],
name: { type: String, required: true, index: { unique: true } }
});
linkedUsers is an array that only receives Ids of other users.
I've tried this as well:
User.findOne({ _id: fromUserId }, function(err, user) {
user.linkedUsers.pull(idToDelete);
user.save();
});
But with no luck.
The second option seem to almost work when i console the lenghts of the array at different positions but after calling save and checking, the length is still at 36:
User.findOne({ _id: fromUserId }, function(err, user) {
console.log(user.linkedUsers.length); // returns 36
user.linkedUsers.pull(idToDelete);
console.log(user.linkedUsers.length); // returns 35
user.save();
});
So it looks like i'm close but still, no luck. Both Ids are sent via the frontend side of the app.
I'm running those versions:
"mongodb": "^2.2.29",
"mongoose": "^5.0.7",
Thanks in advance.
You need to explicitly define the types in your schema definition i.e.
groups: [{ type: Schema.Types.ObjectId, ref: 'Group' }],
linkedUsers: [{ type: Schema.Types.ObjectId, ref: 'User' }]
and then use either
User.findOneAndUpdate(
{ _id: fromUserId },
{ $pullAll: { linkedUsers: [idToDelete] } },
{ new: true },
function(err, data) {}
);
or
User.findByIdAndUpdate(fromUserId,
{ $pullAll: { linkedUsers: [idToDelete] } },
{ new: true },
function(err, data) {}
);
I had a similar issue. I wanted to delete an object from an array, using the default _id from mongo, but my query was wrong:
const update = { $pull: { cities: cityId }};
It should be:
const update = { $pull: { cities: {_id: cityId} }};
