I have already uploaded another challange1 . Go through that code briefly and then come to this example.
If you already have studied that previous challange1 now you are ready for this challange2.
follow my github account for more of these mongoose concepts
const mongoose = require('mongoose');
main().catch(err => console.log(err));
async function main() {
await mongoose.connect('mongodb://127.0.0.1:27017/PersonData');
const personSchema = new mongoose.Schema({
name: {
first: { type: String, required: true, lowercase: true, trim: true },
last: { type: String, required: true, uppercase: true, trim: true }
},
username: {
type: String,
required: true,
lowercase: true,
trim: true,
minLength: 6,
maxLength: 25,
},
email: {
type: String,
required: true,
uppercase: true,
trim: true,
minLength: 6,
maxLength: 35,
},
living: Boolean,
updated: {
type: Date,
default: Date.now,
},
age: {
type: Number,
min: [18, 'You are too young to be in profession'],
max: [65, 'Now you can retire...'],
},
occupation: {
type: String,
required: true,
}
});
// compile our model
const Person = mongoose.model('Person', personSchema);
// create a document
await Person.insertMany([
{
name: {
first: 'Mayuk',
last: 'Mukherjee',
},
username: "Mayuk_ProgrammER_USER",

]);
const allPerson = await Person.find({});
console.log(allPerson);
for (var i = 0; i < allPerson.length; i++){
console.log("first Name = " + allPerson[i].name.first + ", last Name = " + allPerson[i].name.last);
console.log("userName = "+allPerson[i].username);
console.log("email = "+allPerson[i].email);
console.log("living = "+allPerson[i].updated);
console.log("updated = "+allPerson[i].age);
console.log("occupation = "+allPerson[i].occupation);
}
}
Here is the output :
