multer file upload doesn't show the path where file is stored

Question

I'm using node, express and multer to upload files in angular application while having mongoDB for the database. When I'm uploading a file, although it's getting uploaded in the destination folder called uploads which I declared as static in my index.js, it's path where the file is saved is not shown in the database and remains blank as a default value. Below is a snap of my database when the form is created and the image is also uploaded but the imagePath field where the location should be remains blank

{
    "title": "title to check file upload second time",
    "description": "checking file upload check",
    "bodyHtml": "",
    "views": 0,
    "isPublished": true,
    "category": "Drama",
    "author": "",
    "imagePath": "",
    "_id": "5e399bd4de5df134604a662f",
    "blogId": "ZSiEu37z",
    "created": "2020-02-04T16:29:08.000Z",
    "lastModified": "2020-02-04T16:29:08.000Z",
    "__v": 0
}

multer settings on the controller:

const multer = require('multer')

 const storage = multer.diskStorage({
     destination: function(req, file, cb) {
         cb(null, './uploads/')
     },
     filename: function(req, file, cb) {
         cb(null, Date.now() + file.originalname)
     }
 })

 const upload = multer({storage: storage})
let setRouter = (app) => {
    let baseUrl = appConfig.apiVersion+'/blogs';

app.post(baseUrl+'/create', upload.single('imagePath'), (req, res) => {
    var today = time.now()
    let blogId = shortid.generate()
    let newBlog = new BlogModel({

        blogId: blogId,
        title: req.body.title,
        description: req.body.description,
        imagePath: req.body.imagePath

    }) // end new blog model

    newBlog.save((err, result) => {
        if (err) {
            console.log(err)
            res.send(err)
        } else {
            res.send(result)

        }
    }) // end new blog save
})

blog model

// importing mongoose module
const mongoose = require('mongoose')
// import schema 
const Schema = mongoose.Schema;

let blogSchema = new Schema(
    {
        blogId: {
            type: String,
            unique: true,
            index: true
        },
        title: {
            type: String,
            default: ''
        },
        description: {
            type: String,
            default: ''
        },
        imagePath: {
            type: String,
            default: ''
        }
    }
)

mongoose.model('Blog', blogSchema);

inside controller function while saving the json object use req.file.path instead of req.body.imagePath as a value of imagePath
