These the response for user that Im getting from get request to profile API
"user": "5cc3a4e8d37a7259b45c97fe"
What I'm looking for instead is
"user":{
"_id": "5cc3a4e8d37a7259b45c97fe",
"name":"Jhon Doe",
}
Here is my code:
Profile.findOne({
user: req.user.id
})
.populate('user',['name']) // I added this line to populate user object with name
.then(profile=>{
if(!profile){
errors.noprofile = 'There is no profile for this user'
return res.status(404).json(errors);
}
res.json(profile)
})
.catch(err => res.status(404).json(err));
However, Im getting these error:
{
"message": "Schema hasn't been registered for model \"users\".\nUse mongoose.model(name, schema)",
"name": "MissingSchemaError"
}
What am I missing
Profile Schema
const ProfileSchema = new Schema({
user:{
type: Schema.Types.ObjectId,
ref: 'users'
},
handle: {
type: String,
required: true,
max: 40
},
company: {
type: String
},
website: {
type: String,
}
})
Here is how my Users schema looks like
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
// Create Schema
const UserSchema = new Schema({
name:{
type: String,
required: true,
},
email:{
type: String,
required: true,
},
password:{
type: String,
required: true,
},
avator:{
type: String,
},
date:{
type: Date,
default: Date.now,
}
});
module.exports = User = mongoose.model('Users', UserSchema)
Schema that you are referencing in Profile schema is users, but you have saved your user schema as Users. So I would say that you need to update your Profile schema:
const ProfileSchema = new Schema({
user:{
type: Schema.Types.ObjectId,
ref: 'Users'
},
handle: {
type: String,
required: true,
max: 40
},
company: {
type: String
},
website: {
type: String,
}
})
Name under which is saved your User schema can be found in this line
module.exports = User = mongoose.model('Users', UserSchema)
The error says you don't have Schema for Users. You reference it from Profile Schema, but you don't have it. It can be this way:
const Users = new Schema({
name: String
})

I am new to mongoose js so i wanted to create a contact feild only one time the user fills a form
here is my contact model
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const ContactSchema = new Schema({
fname: {
type: String,
required: true,
default:"fname"

lname: {

type:String,
required:true,
default:""
}
});
module.exports = Contact = mongoose.model('Contact', ContactSchema);
here is my user model
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
// Link Schema
const LinkSchema = require('./Link').schema;
const ContactData=require('./conatct').schema;
// Create User Schema
const UserSchema = new Schema({

}
});
module.exports = User = mongoose.model('user, UserSchema);
** suggest me some queries for creating contact details only once the user enters the data i have tried from user.contact.push({}) but it creates multiple object in contact array**
If I get you, you want the contact field to be a single object not an array of objects then change
//change
contact:{
type:[ContactData]
}
//to
contact:ContactData
// when you want to add data you just do something like
const user = new User({
name,etc...,
contact.mobile:user_mobile, etc..
})
I have an array of objectIDs references in mongo. I want to get a specific element in that array after populating the objectIDs. the problem is i get an empty array.
Here's my schema

},
date:{
type:String,

},
jointes: {
type:Array
},
questionnaire: {

},
}, { collection : 'patients'} );
const patients = mongoose.model('Patient', patientSchema);
Consultation schema
const consultationSchema = new mongoose.Schema({

},
motif:{
type: String,
},
observations: [{
type: mongoose.Schema.Types.ObjectId,

ordonnances: [{
type: mongoose.Schema.Types.ObjectId,
ref: "Ordonnance"
}]
});
const consultations = mongoose.model('Consultation', consultationSchema);
the exports
module.exports = {
patients: patients,
consultations: consultations,
}
The router where i'm trying to populaet consultation field and then get the item
const {patients} = require('./patient.models')
const {consultations} = require('./patient.models')
// not working , getting empty array
const patient = await patients.find({"consultations.motif" : "Checking"}).populate('consultations')
res.send(patient)
The mongo db record , to show you that the field does exist
Here's what i get when i do make the following query iwthout specifiying the field
const patient = await patients.find().populate('consultations')
res.send(patient)
This question already has been answered here: Find after populate mongoose
Here is the solution for your case which does not involve changing the database structure:
const patient = await patients.find().populate({
path: 'consultations',
match: {
motif: 'Checking'
}
})
res.send(patient)
I have a ProfileSchema that I want to keep track of posts that have been posted. When I save a new Post it has a Profile_id but when I fetch the profile entry the posts array is empty. How does this work?
Profile Schema
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const ProfileSchema = new mongoose.Schema({
user: {
type: Schema.Types.ObjectId,
ref: 'users'
},
handle: {
type: String,
required: true,
max: 40
},
posts: [
{
type: Schema.Types.ObjectId,
ref: 'posts'
}
],date:{
type: Date,
default: Date.now
}
})
module.exports = Profile = mongoose.model('profile', ProfileSchema);
Post Schema
const PostSchema = new Schema({
user: {
type: Schema.Types.ObjectId,
ref: 'users'
},
profile: {
type: Schema.Types.ObjectId,
ref: 'profile'
},
title: {
type: String,
required: true,
max: 40
},
body: {
type: String,
required: true
},
date: {
type: Date,
default: Date.now
}
})
module.exports = Profile = mongoose.model('posts', PostSchema)
how I save it
router.post('/', passport.authenticate('jwt', {session: false}), (req,res) => {
const newPost = new Post({
title: req.body.title,
body: req.body.body,
img: req.body.img,
user: req.user._id,
profile: req.body.profile_id
});
newPost.save().then(post => res.json(post));
})
I'm a bit confused the mongoose documentation uses syntax I'm not familiar with or haven't learned their way yet. my user populates when I fetch for the profile data but the posts array is blank when I populate it.

i need to do this;
every product data must be have category
if one day,one category's name changed then every product that relation with that category must changed
i am trying to set category id to product schema and when i fetch the data it must be comes every product with category name as json
i am really confused if you help me i'd be really thankful
You can set up your category as :
category: {
type: mongoose.Schema.Types.ObjectId,
ref: 'category' //your model name
}
You can wrap it into an array and name it categories if you want multiple categories.
Then when you get the data, you will have to execute new Product().populate('category') to get retrieve the category data instead of just returning the category ObjectId.
I am trying to populate my users car inventory. All the cars have a userId attached to them when they are created but when I go to populate the inventory it doesn't work and I get no errors.
Here are my models:
User.js
let UserSchema = mongoose.Schema({
username: {
type: String,
required: true,
unique: true
},
password: {
type: String,
required: true
},
inventory: [{ type: mongoose.Schema.Types.ObjectId, ref: 'Car' }]
});
let User = mongoose.model('User', UserSchema);
models.User = User;
Cars.js
let CarSchema = mongoose.Schema({
userId: {
type: mongoose.Schema.Types.ObjectId,
ref: 'User'
},
make: {
type: String,
required: true
},
model: {
type: String,
required: true
},
year: {
type: String
}
});
let Car = mongoose.model('Car', CarSchema);
models.Car = Car;
Here is the populate code:
router.route('/users/:user/inventory').get((req, res) => {
User.findById(userId)
.populate('inventory')
.exec((err, user) => {
if (err) {
console.log("ERRROORRR " + err)
return res.send(err);
}
console.log('Populate ' + user)
res.status(200).json({message: 'Returned User', data: user});
});
});
};
This is what a car object looks like in the database:
{
"_id": ObjectId("5759c00d9928cb581b5424d0"),
"make": "dasda",
"model": "dafsd",
"year": "asdfa",
"userId": ObjectId("575848d8d11e03f611b812cf"),
"__v": 0
}
Any advice would be great! Thanks!
Populate in Mongoose currently only works with _id's, though there's a long-standing issue to change this. You'll need to make sure your Car model has an _id field and that the inventory field in User is an array of these _id's.
let CarSchema = new mongoose.Schema(); //implicit _id field - created by mongo
// Car { _id: 'somerandomstring' }
let UserSchema = new mongoose.Schema({
inventory: [{
type: mongoose.Schema.Types.ObjectId,
ref: 'Car'
}]
});
// User { inventory: ['somerandomstring'] }
User.populate('inventory')
