How to create nested object in MongoDB schema, nested object and array MEAN stack - json

Question

I'm trying to design a nested MongoDB schema.
Currently, I have this schema and it's working:
var CompanySchema = new mongoose.Schema({
name: String,
rate: number
date: Date
})
But I wanna expend it to get:
var CompanySchema = new mongoose.Schema({
name: String,
currency: {
mxn: Number,
php: Number,
},
source: [String],
deliveryMethod: [String],
date: Date
})
For source, I want to get an array of inputs ex. ["bank", "debit card", "agent"]
and almost samething for deliverymethod.
But either my input is wrong or my schema, because the value for source saves as one long string, not a separated value.
Also, I think the way I designed the currency to have more currency rate is correct but I don't know how my input json should suppose to be.
I tried it in postman:
{
"name": "google",
"currency": {
"mxn": 20,
"php": 30
}
}
and this is the result i got:
{
"status": 201,
"data": {
"__v": 0,
"name": "google",
"date": "2017-12-06T22:38:45.896Z",
"_id": "5a2871752e3b7343dc388549",
"deliveryMethod": [
null
],
"source": [
null
]
},
"message": "Succesfully Created Company"
}
1- if my currency nested schema is correct how should be my post json file be?
2- how can I get source and deliveryMethod as an array of string?

Answer 1

The JSON in the request body should look like this:
{
"name": "google",
"currency": {
"mxn": 20,
"php": 30
},
"source": ["source1", "source 2", "source 3"],
"deliveryMethod": ["delMetd 1", "delMetd 2", "delMetd 3"],
"date": "2015-11-27T23:00:00Z"
}
I copy/pasted your code and tried with Postman. The response I got back was:
{
"__v": 0,
"name": "google",
"date": "2015-11-27T23:00:00.000Z",
"_id": "5a2915295c5f714f7cb25d90",
"deliveryMethod": [
"delMetd 1",
"delMetd 2",
"delMetd 3"
],
"source": [
"source1",
"source 2",
"source 3"
],
"currency": {
"mxn": 20,
"php": 30
}
}
If I connect to the database with the mongo shell and run db.companies.find().pretty() I get this result:
{
"_id" : ObjectId("5a2915295c5f714f7cb25d90"),
"name" : "google",
"date" : ISODate("2015-11-27T23:00:00Z"),
"deliveryMethod" : [
"delMetd 1",
"delMetd 2",
"delMetd 3"
],
"source" : [
"source1",
"source 2",
"source 3"
],
"currency" : {
"mxn" : 20,
"php" : 30
},
"__v" : 0
}
Your schema is fine. You can try dropping the collection (db.companies.drop()) if you can't get it to work. Start with a fresh one if you don't have any important data in it.
