I'm trying to make an application that requires image uploading and storing, I'm using Express, Mongoose and Multer and trying to upload to MongoDB.
Currently when I try to upload an image, Multer does create a folder and store the image in that folder, but it doesn't save the item to the database and it crashes the server giving the error : ObjectParameterError: Parameter "obj" to Document() must be an object, got itemImages\034ed9d34a3b034becdb415d67b7d193.
Adding to the database works fine without trying to add the image with multer.
My Code:
item_controller.js:
const Item = require('../models/item_schema');
const addItem = (req, res) => {
let itemData = req.body
let itemImage = req.file.path
Item.create(itemData, itemImage)
.then((data) => {
if (data) {
res.status(201).json(data)
}
})
}
module.exports = {
addItem
}
item_schema.js
const { Schema, model} = require('mongoose')
const itemSchema = new Schema({
title: {
type: String,
required: [true, 'Title field is required.']
},
description: {
type: String,
required: [true, 'Description field is required.']
},
itemImage: {
type: String,
required: [true, 'Image field is required.']
},
userID: {
type: Schema.Types.ObjectId,
ref: "User",
required: [true, 'User field is required']
},
categoryID: {
type: Schema.Types.ObjectId,
ref: "Category",
required: [true, 'Category field is required']
},
qualityID: {
type: Schema.Types.ObjectId,
ref: "Quality",
required: [true, 'Quality field is required']
},
price: {
type: Number
},
claimed:{
type: Boolean
}
}, {
timestamps: true
})
module.exports = model('Item', itemSchema)
server.js:
const express = require('express')
const cors = require('cors')
const jwt = require('jsonwebtoken')
const multer = require('multer');
const upload = multer({dest: 'itemImages/'});
require('dotenv').config()
require('./db')()
const { addItem } = require('./controllers/item_controller')
const { loginRequired } = require('./controllers/user_controller')
const app = express()
app.use(cors())
app.use(express.json())
app.post('/items', upload.single('itemImage'), loginRequired, addItem)
app.listen(port, () => {
console.log(`Example app listening on port ${port}`)
})
In your item_controller.js try this:
const addItem = (req, res) => {
let itemData = req.body
let itemImage = req.file.path
Item.create({
title: itemData.title,
description: description ,
itemImage: itemImage ,
userID: item.userID ,
categoryID: item.categoryID ,
qualityID: item.qualityID,
//put all data that are required here...
}, (err,, data)=> {
if (err) return handleError(err) //here you custom handleError of Just res.status(400).json(err);
res.status(201).json(data)
})
}
Model.create receive as a first params all that property you want to save in your Model and second params it a closure.
