I have a mongodb object, the model is given below, I want to add contents to the existing array
var UsersSchema = new Schema({
name: {
type: String,
required: true
},
EmpId: {
type: string,
required: true
},
feed:[{
status: {
type: String
},
comments: {
type: String
},
posted_date: {
type: Date,
default : Date.now
}
}]
});
using a PUT or POST can I add contents to an existing document's feed array.please check the below code
router.put('/api/user1', function(request, response){
Model.findById(request.body._id, function(err, user){
console.log(user.feed);
if(err){
response.status(404).send(err);
}
else {
user.update(
{_id: user._id },
{ $addToSet:
{ feed: user.feed }})
}
})
});
You should use $push to add to an array in Mongo after you find your document.
user.update(
{_id: user._id },
{ $push:
{ feed: user.feed }
})
Try:
user.update({_id: user.id}, {$addToSet: {feed: {$each: user.feed}}});
If you use $addToSet or $push without $each it will push the entire array onto the array in mongo, not each entry.

Here is a relevant part of my Schema, where I'll make reservations to a "space":
var spaceSchema = new mongoose.Schema({
spaceName: String,
scheduledDates: [{
scheduledDates: String,
author: {
id: {
type: mongoose.Schema.Types.ObjectId,
ref: 'User'
},
username: String
}
}]
});
Author should be the current user that's logged in. Here is my route to update those fields:
router.put('/:space_id/schedule', function(req, res) {
Space.findByIdAndUpdate(req.params.space_id, {
'$push': { 'scheduledDates': req.body.space, 'author': req.user._id }
}, { "new": true, "upsert": true }, function(err, space) {
if (err) {
console.log(err);
} else {
console.log(req.body.space);
}
});
});
I can't access "author" correctly, because it's inside the array. What can I do to update this array, adding a new date and user to make the reservation?
Thank you
UPDATE
I tried to use "_id" instead of "id" in my property but got the same result. It seems like it's ignoring the "author" field, and only saving "scheduledDates"
So the schema was like this:
scheduledDates: [{
scheduledDates: String,
author: {
_id: {
type: mongoose.Schema.Types.ObjectId,
ref: 'User'
},
username: String
}
}]
And then in my route, I changed what I was 'pushing':
'$push': { 'scheduledDates': req.body.space, 'author._id': req.user._id }
UPDATED 2
Changed the way I was getting the object to push:
'$push': {
'scheduledDates': {
'scheduledDates': req.body.space,
'author': { _id: req.user._id, username: req.user.username }
}
}
Now I'm getting the following error:
message: 'Cast to string failed for value "{ scheduledDates: \'04/11/2017\' }" at path "scheduledDates"',
name: 'CastError',
stringValue: '"{ scheduledDates: \'04/11/2017\' }"',
kind: 'string',
value: [Object],
path: 'scheduledDates',
reason: undefined } } }
This is the model I am working with:
name: {
type: String
},
payment: {
id: {
type: String,
required: true
},
cards: [
{
id: {
type: String
},
is_default: {
type: Boolean,
"default": false
}
}
]
}
I want to add a card to the cards array, for example:
card =
id: "some_token"
is_default: true
I am using the update method to push the card to the array, but it won't add the card to the document. Instead, it creates a new document with only those fields:
{
id: "some_token",
is_default: true,
_id: someId
}
Any idea how I can update the actual document I am targeting instead of creating a new document?
Here's my code (using CoffeeScript):
update_where =
payment:
id: "some_id"
update_push =
$push:
'payment.cards':
id: card_token
is_default: false
Customer.update update_where, update_push, {upsert: true}, (err, results) ->
# Do something with the results
Oh… I just noticed my mistake. The problem was in the where statement.
I was doing:
payment:
id: "some_id"
But the right thing to write is the following:
'payment.id': 'some_id'
And it now works!
I currently have a schema which looks as follows:
positionsApplied:[{
position_id:String,
index_position: Number
}],
I also have 3 objects which I need to insert into my database:
How can I insert these into my database through an Ajax call? What Ive tried so far:
Adding the data to an array like this:
["58d6b7e11e793c9a506ffe8f", 0, "58c2871414cd3d209abf4fc1", 1, "58d6b7e11e793c9a506ffe7f", 1]
Which would then be passed through my ajax call like this?(unsure)
$.ajax({
url: "/insertPositionIndex",
type: "POST",
dataType: "json",
data: {
newarray
},
success: function (data) {
console.log(data);
}
})
Inserting into the database is where I'm stuck, how do I break down the array in order to insert it?
app.post('/insertPositionIndex', function(req, res){
var object = req.body.ordered_divs;
console.log(req.body);
User.update(
{ "_id": req.user._id},
{ "$push":
{"positionsApplied":
{
// unsure what to do here?
}
}
}
).exec(function (err, result) {
console.log(result);
res.send({ results: result });
});
});
Any help is greatly appreciated!
* Note the position_id field in the schema is the div_id in the array, also the index-position field is the index_pos in the array.

Since your Schema is an array of objects and the data that you are getting(as per console of the browser) is also an array of objects why don't you just pass that array itself(the one in the console of the browser) through ajax and use the $each of mongodb $push to save it into the database.
$.ajax({
url: "/insertPositionIndex",
type: "POST",
dataType: "json",
data: {
arrayOfObjects
},
success: function (data) {
console.log(data);
}
})
app.post('/insertPositionIndex', function(req, res){
var object = req.body.ordered_divs;
console.log(req.body);
User.update(
{ "_id": req.user._id},
{
"$push":
{
"positionsApplied":{
$each: req.body.arrayOfObjects
}
}
}
).exec(function (err, result) {
console.log(result);
res.send({ results: result });
});
});
You will have to change the arrayOfObjects keys to match that of your schema positionsApplied keys.
I'm trying to send an object to an array in my model, but every time I do, the array is still empty.
I pass the object to the backend and it arrives here:
var addFavoriteRecipe = function(req, res){
if(req.user){
console.log(req.body);
userModel.User.find({_id: req.user._id}, {$push :{favoriteRecipes: {name: req.body.alias, _id: req.body._id}}}, function(err){
if(err){
res.send(err);
}else{
res.send("success!");
}
});
}else{
var sendBackError = {err: true, message: "You are not logged in."}
res.send(sendBackError);
}
}
The console log on req.body shows all the data I passed back, and has the two fields I'm trying to push into the array.
Here is my Model:
var userSchema = mongoose.Schema({
username: {
type: String,
required: true,
unique: true
},
email: {
type: String,
required: true,
unique: true
},
password: {
type: String,
required: true
},
friendsList: {
type: Array,
},
favoriteRecipes: {
type: Array,
}
});
I've toyed around with the code, but I really am lost as to where I should go from here. I want to think it's something on my model, but I'm not entirely sure.
You can define your model for an array of objects, either this way:
favoriteRecipes: [{
_id: ObjectId,
name: String
}]
or
favoriteRecipes: { type : Array , "default" : [] }
but, The problem seems to be here:
userModel.User.find(
{_id: req.user._id},
{ $push : {favoriteRecipes: {name: req.body.alias, _id: req.body._id}}},
function(err){
if(err){
res.send(err);
}else{
res.send("success!");
}
});
You are using find you need to change it to update:
userModel.User.update(
{_id: req.user._id},
{ $push : { favoriteRecipes: {name: req.body.alias, _id: req.body._id}}},
function(err){
if(err){
res.send(err);
}else{
res.send("success!");
}
});
I have this code:
router.post('/setsuggestions', function(req, res, next){
if(!req.body.username || !req.body.challengessuggestions){
return res.status(400).json({message: challengessuggestions});
}
var query = { username: req.body.username };
/*User.findOneAndUpdate(query, { challengessuggestions: req.body.challengessuggestions }, callback = function(response){
res.json(response);
});*/
/*
User.findOneAndUpdate(
query,
{$push: {"challengessuggestions": {$oid: req.body.challengessuggestions}}},
callback = function(response) {
res.json(response);
}
);*/
User.findOneAndUpdate(
query,
{$push: {challengessuggestions: req.body.challengessuggestions}},
{safe: true, upsert: true},
function(err, model) {
res.json(err);
}
);
});
When I postman like this:
I get the following error:
{ "name": "MongoError", "message": "exception: The field
'challengessuggestions' must be an array but is of type OID in
document {_id: ObjectId('56263b910d1a2f1f0077ffae')}", "errmsg":
"exception: The field 'challengessuggestions' must be an array but is
of type OID in document {_id: ObjectId('56263b910d1a2f1f0077ffae')}",
"code": 16837, "ok": 0 }
This is the schema definition of AppUser:
var UserSchema = new mongoose.Schema({
username: { type: String, lowercase: true, unique: true },
firstname: { type: String},
lastname: { type: String},
difficulty: { type: String},
isstudent: { type: Boolean },
haschildren: { type: Boolean},
gender: { type: String },
email: { type: String, unique: true},
birthdate: String,
isdoingchallenges: { type: Boolean },
challengescompleted: [{ type: ObjectId, ref: 'Challenge' }],
currentchallenge: { type: ObjectId, ref: 'Challenge' },
challengessuggestions: [{ type: ObjectId, ref: 'Challenge' }],
hash: String,
salt: String
});
This is the schema definiton of challenge:
var Challengeschema = new mongoose.Schema({
name: { type: String, initial: true, required: true, index: true },
image: { type: Array },
difficulty: { type: String },
studentfriendly: { type: Boolean },
childfriendly: { type: Boolean },
description: { type: String }
});
I'm sending this in the function that calls the api:
Object {_id: "5631423f8c5ba50300f2b4f6", difficulty: "medium", name:
"Probeer 1 van onze recepten.", __v: 0, childfriendly: true…}
This gives me following error:

How do I solve this?
Query the User user using findOne() first and use the first found document that's passed to the callback to save the embedded documents with:
router.post('/setsuggestions', function(req, res, next){
if(!req.body.username || !req.body.challengessuggestions){
return res.status(400).json({message: challengessuggestions});
}
var query = { username: req.body.username };
User.findOne(query, function (err, user){
if (err) //throw ...
if (user) {
if (user.challengessuggestions && user.challengessuggestions.length) {
user.challengessuggestions.push(req.body.challengessuggestions);
}
else {
user.challengessuggestions = [req.body.challengessuggestions];
}
// save changes
user.save(function (err) {
if (!err) {
// done ...
}
});
}
});
);
