Refresh the mongoose schema to add a new property

Question

I am trying to update a schema to add a new property field. I was hoping this would be as simple as adding a property to the schema with an updated field available.

I have an existing scheme

  let userDrinkSchema = new mongoose.Schema({  new Schema
    creator : { 
        type: mongoose.Schema.Types.ObjectId, 
        ref: 'user'  // name of user file
    },
    caffeine: Number,
    mgFloz: Number,
    name: String,
    size: Number,
    updated_at: {
        type: Date,
        default: Date.now()
    }
});

I need to add id from this schema

const UserSchema = mongoose.Schema({

const User = module.exports = mongoose.model('User', UserSchema);

I am not sure how to add this property for each user. I completed this example Working with schema changes in Mongoose

Now this diagram:

let DrinkSchema = new mongoose.Schema({
    user: { 
        type: mongoose.Schema.Types.ObjectId, 
        ref: 'user',
        required: true,
        default: null
    },
    caffeine: Number,
    mgFloz: Number,
    name: String,
    size: Number,
    imageUrl: String,
    date: {
        type: Date,
        default: Date.now()
    }
},
{
    collection: 'drinkList'
});

Unfortunately, the user also matters to me

{
 "_id":"58bba13bb7afeaa3180aa929",
 "caffeine":422,"mgFloz":218.7,
 "name":"10 Hour Energy Shot",
 "size":1.93,
 "url":"/caffeine-content/10-hour-eternal-shot",
 "date":"2017-03-28T13:10:12.650Z",
 "user":null
}

Is there a way to update a user field to get user information? The circuit I am referring to is configured as

const SelectedDrinks = require('./userDrinks').schema;
const UserSchema = mongoose.Schema({
    name: {
        type: String
    },
    email: {
        type: String,
        required: true
    },
    username: {
        type: String, 
        required: true
    },
    password: {
        type: String,
        required: true
    },
    caffeine_list: [SelectedDrinks]
})

I see that mongodb adds an id to each user when it is created. this is what i am trying to access.

- . , . , .

    router.post('/addDrink', (req, res, next) => {
    let newDrink = new UserDrinks({
        creator: req.body.creator, // need id get user object id()
        caffeine: req.body.caffeine,
        mgFloz: req.body.mgFloz,
        name: req.body.name,
        size: req.body.size,
        updated_at: req.body.updated_at
    });

    newDrink.save( (err) => {
        if(err) {
            res.send(err);
        } else {
            User.findOne({ _id: newDrink.creator},  (err, user) => {
                user.caffeine_list.addToSet(newDrink)
                user.save( function (err) {
                    if(err) {
                        console.log(err);
                    }else {
                        res.status(201).json(newDrink);
                    }
                })
            })

        }

    })
});

Answer 1

, creator user. 2 :

• /addDrink
• drinkList

1) newDrink, user creator:

let newDrink = new UserDrinks({
    user: req.body.creator,
    caffeine: req.body.caffeine,
    mgFloz: req.body.mgFloz,
    name: req.body.name,
    size: req.body.size,
    updated_at: req.body.updated_at
});

2) UserDrinks, :

UserDrinks.update({}, { $rename: { "creator" : "user" } }, { multi: true }, callback)

UserDrinks creator user.

- -, / , t . :

function renameCreatorField() {
    UserDrinks.update({}, { $rename: { "creator" : "user" } }, { multi: true }, function(err, data) {
        if (!err) { 
            //success 
        }
    })
}

renameCreatorField();
