Update model with Mongoose, Express, NodeJS

Question

I\'m trying to update an instantiated model (\'Place\' - I know it works from other routes) in a MongoDB and have spent a while trying to properly do so. I\'m also trying t

Answer 1

you could do something similar based on the illustration below

Updated:

In My solution: I have created a model, controller and route to depict the similar scenario (interacting with MongoDB method like updating/creating data to the database) in Nodejs MVC framework with MongoDB as the database

// user.js - this is the user model

const mongoose = require('mongoose')
const validator = require('validator')

const User = mongoose.model('User', {
  name: {
    type:  String,
    required:  true,
    trim:  true
  },
  email: {
    type:  String,
    required:  true,
    trim:  true,
    lowercase:  true,
    validate(value) {
      if (!validator.isEmail(value)) {
        throw  new  Error('Email is invalid')
      }
    }
  },
  password: {
    type:  String, 
    required:  true, 
    minlength:  7, 
    trim:  true,
    validate(value) {
      if (value.toLowerCase().includes('password')) { 
        throw  new  Error('Password cannot contain "password"') 
      } 
    } 
  },
  age: { 
    type:  Number, 
    default:  0, 
    validate(value) { 
      if (value  <  0) { 
        throw  new  Error('Age must be a positive number') 
      }
    }
  }
});   

module.exports  =  User

// userController.js**

exports.updateUser = async(req, res) => {
  const updates = Object.keys(req.body)
  const allowedUpdates = ['name', 'email', 'password', 'age']
  const isValidOperation = updates.every((update) => { 
    allowedUpdates.includes(update))
    if (!isValidOperation) {
      return res.status(400).send('Invalid updates!')
    }
    try {
      const user = await UserModel.findByIdAndUpdate(req.params.id, 
        req.body, { new: true, runValidators: true })
      if (!user) {
        return res.status(404).send({ message: 'You do not seem to be registered' })
      }
      res.status(201).send(user)
    } catch (error) {
      res.status(400).send(error)
    }
}

// **router.js**
router.patch('/user/:id', userController.updateUser)
