Mongoose Nested Schema - required fields inside array field - mongodb

Question

I have following mongoose schema -
const UserSchema = new mongoose.Schema({
name: {type: String, required: true, trim: true},
email: {type: String, required: true, trim: true},
password: {type: String, required: true, trim: true},
addresses: [{
type: {type: String, required: true, trim: true},
pinCode: {type: String, required: true, trim: true},
city: {type: String, required: true, trim: true},
state: {type: String, required: true, trim: true},
landmark: {type: String, required: false, trim: true},
}]
})
only name, email and password are required for registration. User can have more than one address , and each address has some required fields like in flipkart.com/account/addresses user's account page.
Each address will be stored in addresses array field in mongodb database.
I want to keep addresses array [ ] when user register. address are only provided through user's account page web page.
But I am getting ValidatorError because schema of doc inside addresses array having required fields.
when user register -
{
name: 'rahul',
email: 'rahul#example.com',
password: 'pass123',
addresses: []
}
user is already registered, and then add address
{
name: 'rahul',
email: 'rahul#example.com',
password: 'pass123',
addresses: [
{
type: 'home',
pinCode: '111222',
city: 'city1',
state: 'state1'
},
{
type: 'work',
pinCode: '333444',
city: 'city2',
state: 'state2',
landmark: 'landmark2'
}
]
}
How to achieve above ??
Any help would be appreciated.

Answer 1

You just have to remove required:true field from address array not even required:false.
Just type and trim will the job and required is false by default so you dont have to include it.

Answer 2

I was doing this -
const userDoc = new UserModel({
name: nm,
email: em,
password: pass,
addresses: []
})
Not passing addresses: [], prevent error ValidatorError
const userDoc = new UserModel({
name: nm,
email: em,
password: pass
})

Try the below code. Hope this will help you.
const ToySchema = new mongoose.Schema({ name: String });
const ToyBoxSchema = new mongoose.Schema({
toys: [ToySchema],
bucketName: String,
numToys: Number
});
const ToyBox = mongoose.model('ToyBox', ToyBoxSchema);
var toyBoxData = {
toys : [
{ name : "Dummy Toy 1"},
{ name : "Dummy Toy 2"},
{ name : "Dummy Toy 3"},
],
bucketName: "My Toy Bucket",
numToys: 3
}
var toyBucket = new ToyBox(toyBoxData);
toyBucket.save( (err: any)=> {
console.log(err);
})
And when you will run the above code, you will be able to see a collection and document like this in your DB, as in the below screenshot.
