Mongoose getters are either not working the way I want or I'm misunderstanding what they are - mongodb

Question

I created some sample code to demonstrate my issue on a smaller scale. From my understanding, a getter function will not affect anything on my database, but when I want to make a get request to view items on my database, it will change the value to whatever is returned only when the data is displayed. However, when I make my get request to view items on my database, the item I am shown is exactly how it was saved. I'm not sure if I'm misunderstanding what a getter function is, or if my syntax is just incorrect somewhere.
Here is my main server:
const express = require('express')
const mongoose = require('mongoose')
// Linking my model
const User = require('./User')
// Initializing express
const app = express()
const PORT = 9999
app.use(express.json())
// Connecting to mongodb
const connectDB = async () => {
try {
await mongoose.connect('mongodb://localhost/testdatabase', {
useUnifiedTopology: true,
useNewUrlParser: true
})
console.log('Connected')
} catch (error) {
console.log('Failed to connect')
}
}
connectDB()
// Creates a new user
app.post('/user/create', async (req, res) => {
await User.create({
name: 'John Cena',
password: 'somepassword'
})
return res.json('User created')
})
// Allows me to view all my users
app.get('/user/view', async (req, res) => {
const findUser = await User.find()
return res.json(findUser)
})
// Running my server
app.listen(PORT, () => {
console.log(`Listening on localhost:${PORT}...`)
})
Here is my model:
const mongoose = require('mongoose')
// My setter - initialPassword is 'somepassword'
// This seems to work properly, in my database the password is changed to 'everyone has the same password here'
const autoChangePassword = (initialPassword) => {
console.log(initialPassword)
return 'everyone has the same password here'
}
// My getter - changedPassword should be 'everyone has the same password here' I think
// The console.log doesn't even run
const passwordReveal = (changedPassword) => {
console.log(changedPassword)
return 'fakehash1234'
}
// Creating my model
const UserSchema = mongoose.Schema({
name: {
type: String
},
password: {
type: String,
set: autoChangePassword,
get: passwordReveal
}
})
// Exporting my model
const model = mongoose.model('user', UserSchema)
module.exports = model

Answer 1

Not sure if it would help anyone since I found my answer on another StackOverflow post, but the issue was I had to set getters to true when converting back to JSON:
// Creating my model
const UserSchema = mongoose.Schema({
name: {
type: String
},
password: {
type: String,
set: autoChangePassword,
get: passwordReveal
}
}, {
toJSON: { getters: true }
})
Any similar problems can be solved by adding some combination of the following:
{
toJSON: {
getters: true,
setters: true
},
toObject: {
getters: true,
setters: true
}
}
