I have a model with articles, and would like to populate an array of data with all the documents in a collection.
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const ArticlesSchema = new mongoose.Schema({
path: {
type: String,
required: true,
unique: true,
},
base_headline: {
type: String,
required: true,
},
intro: {
type: String,
required: true,
},
featured_image: {
type: String,
required: true,
},
author: {
type: String,
required: true,
},
platform_filter: {
type: String,
},
free_filter: {
type: String,
},
content_type: {
type: String,
required: true,
},
data: [{ type: Schema.Types.ObjectId, ref: 'DesignProducts' }],
date: {
type: Date,
default: Date.now,
},
});
module.exports = mongoose.model('Articles', ArticlesSchema);
The data property should be populated with all documents in the DesignProducts collection.
I tried running this but the data array is still empty:
Article.findOne({ path: slug }).populate('data').exec();
Here is what the designProducts model looks like:
const mongoose = require('mongoose');
const DesignProductsSchema = new mongoose.Schema({
name: {
type: String,
required: true,
unique: true,
},
intro: {
type: String,
required: true,
},
website: {
type: String,
required: true,
},
date: {
type: Date,
default: Date.now,
},
});
module.exports = mongoose.model('DesignProducts', DesignProductsSchema);
This array should be populated with all the documents in the DesignProducts collection:

Hi clever MongoDB people,
I am extremely new to Mongo DB and am trying to teach myself coding but I am battling with the practical side of collections.
I am attempting to create an employee management system and would like to know how do I get the different schemas/collections to only deal with the individual User’s employees.
A user will register using this schema;
const mongoose = require("mongoose");
const UserSchema = new mongoose.Schema({
name: {
type: String,
required: true,
},
email: {
type: String,
required: true,
lowercase: true,
},
companyName: {
type: String,
required: true,
},
password: {
type: String,
required: true,
},
role: {
type: String,
default: "customer",
},
CreatedAt: {
type: Date,
default: () => Date.now(),
},
UpdatedAt: {
type: Date,
default: () => Date.now(),
},
});
const User = mongoose.model("User", UserSchema:
);
module.exports = User;
Then the system takes them to a Profile page where they create a profile;
Profile Schema:
const mongoose = require("mongoose");
const Schema = mongoose.Schema;
const ProfileSchema = new Schema({
userId: {
type: Schema.Types.ObjectId,
required: true,
},
contactPerson: {
type: String,
required: true,
},
companyName: {
type: String,
required: true,
},
mobileNo: {
type: String,
required: true,
},
workNo: {
type: String,
},
email: {
type: String,
required: true,
},
industry: {
type: String,
},
CreatedAt: {
type: Date,
default: () => Date.now(),
},
UpdatedAt: {
type: Date,
default: () => Date.now(),
},
});
const Profile = mongoose.model("Profile", ProfileSchema);
module.exports = Profile;
Then they can add their employees.
Employee Schema:
const mongoose = require("mongoose");
const Schema = mongoose.Schema;
const EmployeeSchema = new Schema({
userId: {
type: Schema.Types.ObjectId,
required: true,
},
employeeNo: {
type: String,
},
title: {
type: String,
},
employeeName: {
type: String,
required: true,
},
surname: {
type: String,
required: true,
},
gender: {
type: String,
},
race: {
type: String,
},
passportNo: {
type: String,
},
IDnumber: {
type: Number,
},
DOB: {
type: Date,
},
aka: {
type: String,
},
midName: {
type: String,
},
marriage: {
type: String,
},
passportExpires: {
type: Date,
},
mobileNo: {
type: String,
},
empEmail: {
type: String,
lowercase: true,
},
CreatedAt: {
type: Date,
default: () => Date.now(),
},
UpdatedAt: {
type: Date,
default: () => Date.now(),
},
});
const Employee = mongoose.model("Employee", EmployeeSchema);
module.exports = Employee;
Once an employee has been created there are various schemas connected with the employee, such as Personal contact details schema, Job details schema, Emergency contact details schema and so on.
This is my Emergency contact details schema:
const mongoose = require("mongoose");
const Schema = mongoose.Schema;
const EmergencySchema = new Schema({
userId: {
type: Schema.Types.ObjectId,
required: true,
},
emergContactPerson: {
type: String,
required: true,
},
emergWorkNo: {
type: String,
},
emergMobileNo1: {
type: String,
required: true,
},
emergMobileNo2: {
type: String,
},
medicAidName: {
type: String,
},
medicPlan: {
type: String,
},
medicMemberNo: {
type: String,
},
medicDepCode: {
type: Number,
},
CreatedAt: {
type: Date,
default: () => Date.now(),
},
UpdatedAt: {
type: Date,
default: () => Date.now(),
},
});
const Emergency = mongoose.model("Emergency", EmergencySchema);
module.exports = Emergency;
My question is How do I create a one-to-many relationship between my schemas so that each User will only see their employees and their personal details?
Please can you help me?
I'm need to create a schema to add restaurts and then show this places on a map on react. like
1-name place
2-author
3-lat
4-log
5-description
6- open hour
this is need to id user connect for now how create and show on the react app and react native app.
you can following this code
const mongoose = require("mongoose");
const { Schema } = mongoose;
const restaurtSchema = new Schema({
title: { type: String, required: true, trim : true },
description: { type: String, required: true },
image: { type: String },
address: { type: String, required: true },
location: {
lat: { type: Number, required: true },
lng: { type: Number, required: true },
},
creator: { type: mongoose.Types.ObjectId, required: true, ref: 'User'},
date: { type: Date, default: Date.now },
});
module.exports = mongoose.model("restaurt", restaurtSchema );
You can 2dsphere index for save location of restaurant and it helps you find nearest restaurant or calculate distance.
const mongoose = require("mongoose");
const { Schema } = mongoose;
const restaurtSchema = new Schema({
title: { type: String, required: true, trim : true },
description: { type: String, required: true },
image: { type: String },
address: { type: String, required: true },
locationLongLat: {
'type': {type: String, enum: "Point", default: "Point"},
coordinates: {type: [Number], default: [0, 0]}
}
creator: { type: mongoose.Types.ObjectId, required: true, ref: 'User'},
date: { type: Date, default: Date.now },
});
restaurtSchema.index({'locationLongLat.coordinates': "2dsphere"});
I am building an e-commerce application. Every store has a delivery range so i want to set delivery range of every store in the database to show the store only to those who falls in the delivery range.
Store Schema.
const mongoose = require("mongoose");
const sellerSchema = new mongoose.Schema({
name:{
type: String,
required: true,
},
type: {
type: String,
required: true
},
location: {
type: {
type: "String",
enum:['Point']
},
coordinates: {
type: [Number],
index: '2dsphere'
}
},
owner: {
type: String,
required: true
},
items: [{
type: mongoose.Schema.Types.ObjectId,
ref: "items"
}],
contact: {
type: String,
required: true
},
loginId: {
index:true,
unique: true,
type: String,
},
password: {
type: String,
required: true
},
createdAt: {
type: Date,
default: Date.now
}
});
const sellerModel = mongoose.model("sellers",sellerSchema);
module.exports = sellerModel;
I have the following Models:
const mongoose = require('mongoose');
mongoose.Promise = global.Promise;
const imputerSchema = new mongoose.Schema({
dninie: {
type: String,
trim: true,
},
name: {
type: String,
trim: true,
required: true,
},
lastname: {
type: String,
trim: true,
required: true,
},
second_lastname: {
type: String,
trim: true,
},
phone : {
type: Number,
unique: true,
trim: true,
},
qr: {
type : String,
unique: true,
default: Date.now
}
});
module.exports = mongoose.model('Imputer', imputerSchema)
const mongoose = require('mongoose');
mongoose.Promise = global.Promise;
const imputationSchema = new mongoose.Schema({
qr: {
type: String,
trim: true,
required: true,
ref: 'Imputer',
},
imputation_date: {
type: String,
default: Date.now,
required: true,
},
coordinates: {
type: [Number, Number],
index: '2d',
},
});
module.exports = mongoose.model('Imputation', imputationSchema);
and I trying to make a query like this:
Imputation.find()
.populate('imputer.qr')
.exec()
.then(docs => console.log(docs));
I also try
Imputation.find()
.populate('imputer')
.exec()
.then(docs => console.log(docs));
But I'm only got the documents on the imputation model without the field on the imputers model.
Here are some screenshots of how the documents look
Change your imputationSchema as follows:
const imputationSchema = new mongoose.Schema({
qr: {
type: mongoose.Types.ObjectId, ref: "Imputer",
trim: true,
required: true,
},
// other fields...
});
and then query like this:
Imputation.find()
.populate('qr')
.exec()
.then(docs => console.log(docs));
I had defined mongoose schema and i tried to insert data into mongodb.But it is not inserted as per defined schema
export const EmpSchema: mongoose.Schema = new Schema({
name: {
type: String,
required: true
},
empNo: {
type: String,
required: true
},
skill: {
type: [String],
required: true
},
address: {
type: String,
required: true
}
}, {
_id: false,
versionKey: false,
retainKeyOrder: true
});
It is getting stored like Array elements as last field.like
name
empno
address
skill
export const EmpSchema: mongoose.Schema = new Schema({
name: {
type: String,
required: true
},
empNo: {
type: String,
required: true
},
skill: {
type: [String],
required: true
},
address: {
type: String,
required: true
}
}, {
_id: false,
versionKey: false,
retainKeyOrder: true
});
YOUR SCHEMA DEFINATION IS CORRECT PLEASE CHECK THE CONTROLLER PART WHERE YOU PUT THE INSERT QUERY . THERE MATTERS A INSERTION ORDER
