How to add reference of one schema to another in Mongoose and inserting data by json?
user.wallet = req.body.wallet won't work.
As far as User is concerned user.wallet is just a simple field of the type ObjectId that store a 24 char hex string-like object: 522abc....
This "reference" is actually a higher level interpretation of Mongoose.
That's why you can't directly do user.wallet = req.body.wallet. You have to do something like this:
var user = new User();…// user.wallet = req.body.wallet; // won't workvar wallet = new Wallet(req.body.wallet) // because Wallet too is a Schema just like Useruser.wallet = wallet.id;…
