I'm trying to update a mongoDB database document for my To-Do list, I'm using Node, Mongoose, Express and Express Router.

Mongoose Schema:

const mongoose = require('mongoose');

const toDoSchema = new mongoose.Schema({

    value: {
        type: String,
    },
    category: {
        type: String,
    },
    _id: {
        type: String
    }
});

module.exports = mongoose.model('toDo', toDoSchema)

Patch code:

router.patch('/changeCategory', async (request, response) =>{
    
    const updateItem = new toDoModel({
        category: request.body.category
    })

    let id = request.body._id
    let category = request.body.category
    
    try{
        await updateItem.findByIdAndUpdate({_id: id},{category: category})
        response.json('Category changed')
    }
    catch (error){
        console.log(error.message)
    }
})

Insomnia request:

PATCH http://localhost:5000/changeCategory
{
    "category":"inProgress",
    "_id": "628de6210da8e45f52217083"
}

and what i get is "updateItem.findByIdAndUpdate is not a function"

mongoose express node.js mongodb

This way is wrong. because you can't use findByIdAndUpdate with updateItem variable ..if you want use findByIdAndUpdate, you should use the imported model, then use this method.

example code:

const toDoModel = require("../models/your-model")

router.patch('/changeCategory', async (request, response) => {
  let category = request.body.category
  const updateItem = new toDoModel({
    category
  })

  let id = request.body._id

  try {
    // This part was changed *****

    await toDoModel.findByIdAndUpdate(id,{category: category})
    response.json('Category changed')

    // *******
  } catch (error) {
    console.log(error.message)
  }
})

I hope this solution helps you.
