Re: Correct MongoDb Relationships

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?

how to create nested schema in nestjs use mongodb

email
password
role
confirmed
id
address
city
street
My user schema should be like this. I want it to appear as a nested schema. separate the address space.
export const UserSchema = new mongoose.Schema({
email: { type: String, unique: true, required: true },
password: { type: String, required: true },
role: { type: String, enum: Role, default: Role.USER },
confirmed: { type: Boolean, default: false },
id: { type: String, default: uuid.v4 },
});
UserSchema.pre('save', async function (next) {
try {
if (!this.isModified('password')) {
return next();
}
const hashed = await bcrypt.hash(this['password'], 10);
this['password'] = hashed;
return next();
} catch (err) {
return next(err);
}
});
interface user
export interface User extends Document {
id:string;
email: string;
password: string;
role: Role[];
address: ?
}
I have to add the address in user. How?
export const AddrSchema= new mongoose.Schema({
city: { type: String, default: "bb" },
street: { type: String, default: "aa" },
})
I think this will solve it.
export const UserSchema = new mongoose.Schema({
email: { type: String, unique: true, required: true },
password: { type: String, required: true },
role: { type: String, enum: Role, default: Role.USER },
confirmed: { type: Boolean, default: false },
id: { type: String, default: uuid.v4 },
address: {
city: { type: String, default: "bb" },
street: { type: String, default: "aa" },
}
});

how to use find in populate (mongoose)

I want to match a string with employee ID, employee Name , project name
My Models : (employee)
const employeeSchema = new mongoose.Schema(
{
employeeID: { type: String, unique: true, required: true },
departmentID: { type: mongoose.Types.ObjectId, ref: 'Department', default: null },
employeeName: { type: String, required: true },
gender: { type: String, default: "", enum: ["Male", "Female"] },

email: { type: String, default: null },
branchName: { type: String, default: "" },
employeeType: { type: String, default: "" },
jobStatus: { type: String, default: "" },
joiningDate: { type: Date, default: "" },
leavingDate: { type: Date, default: "" },
comments: { type: String, default: "" },
managerID: { type: mongoose.Types.ObjectId, ref: 'Employee', default: null },
region: { type: String, default: "" },
}
);
(project)
const projectSchema = new mongoose.Schema(
{
projectName: {type: String, required: true},
tech: {type: String, required: true},
startDate: {type: Date, required:true},
endDate: {type: Date, required:true},
customerID:{type:mongoose.Types.ObjectId, ref:'Customer'}
}
);
(employee-Project)
const employeeProjectSchema = new mongoose.Schema(
{
empID: {type: mongoose.Types.ObjectId, required: true, ref: 'Employee'},
projectID: {type: mongoose.Types.ObjectId, required: true, ref: 'Project'},
allocation: {type: [Number]},
assignStartDate: {type: Date},
assignEndDate: {type: Date},
}
);
I'm running my query from employee-project table which is my main table.
What I wanna do is to match a string with with employeeID and employeeName(employee table) and also with projectName(project table).
What I'm doing right now (which is wrong)
async rpSearch(data): Promise<any> {
try {
const result = await MongooseEmployeeProject.find()
.populate({
path: 'empID',
select: 'employeeID employeeName designation region comments resourceManager',
match:{
type:{data}
}
})
.populate({
path: 'projectID',
select: 'projectName tech startDate endDate customerID'
match:{
type:{data}
})
please guide me
First, path must be the field name of the schema. you set path with "employeeID" but "empID" is correct as employeeProjectSchema's field name.
Second, you set match but there is no type field in your employeeSchema and employeeProjectSchema neither. so you have to remove match.
async rpSearch(data): Promise<any> {
try {
const result = await MongooseEmployeeProject.find()
.populate({
path: 'empID',
select: 'employeeID employeeName designation region comments resourceManager'
})
.populate({
path: 'projectID',
select: 'projectName tech startDate endDate customerID'
})
