How to update a property in a nested array with mongoose - mongodb

Question

I want to push a Date object from my client into the nested array 'completed_dates' but I cannot figure out how to do so, or if I would need to change my schema in order for it to work.
{
_id: 606f1d67aa1d5734c494bf0a,
name: 'Courtney',
email: 'c#gmail.com',
password: '$2b$10$WQ22pIiwD8yDvRhdQ0olBe6JnnFqV2WOsC0cD/FkV4g7LPtUOpx1C',
__v: 35,
habits: [
{
_id: 6081d32580bfac579446eb81,
completed_dates: [],
name: 'first',
type: 'good',
days: 0,
checked: false
},
{
_id: 6081d32f80bfac579446eb82,
completed_dates: [],
name: 'seconds',
type: 'bad',
days: 0,
checked: false
},
]
}
and this is my schema
const habitSchema = new mongoose.Schema({
name: String,
category: String,
color: {
type: String,
},
date_added: {
type: String,
},
completed_dates: {
type: Array,
}
})
const userSchema = new mongoose.Schema({
name: {
type: String,
required: true,
min: 6,
max: 255,
},
email: {
type: String,
required: true,
max: 255
},
password: {
type: String,
required: true,
max: 1024,
min: 8,
},
habits: [habitSchema]
})
Here is what I have tried...
I've tried using findOneAndUpdate, using the document id of the logged in user, and trying to manipulate the update object to drill into the nested array. I can access the habits list of the correct user... using this code, but for this new problem, I want to go one level further and push to the 'completed_dates' array of a specific habit (based on name or _id).
//this only adds a habit object to the habits array.
User.findByIdAndUpdate(req.user._id,
{ $pull: { habits: { _id: itemsToDelete } } },
{ new: true , useFindAndModify: false},
function (err, data) {
if (err) {
res.send(err)
} else {
res.send(data.habits)
}
}
)
I have tried building on this existing code by trying to filter down one more level. (this doesn't work.)
const { date, name} = req.body.update
User.findByIdAndUpdate(req.user._id,
{ $push: { 'habits.$[req.body.name].completed_dates': req.body.date} },
{safe: true, upsert: true, new : true, useFindAndModify: false},
function (err, data) {
if (err) {
res.send(err)
} else {
//data.update
res.send(data.habits)
}
}
)
If anyone can link or help me out, I would appreciate it. Thanks
