How to put image into mongodb using node js

Question

I want to put a profile image into the users collection in mongodb, and I'd like to retrieve this image when user fetch his profile.

var storage = multer.diskStorage({
    destination: (req, file, cb) => {
        cb(null, 'uploads/')
    },
    filename: (req, file, cb) => {
        cb(null, file.fieldname + '-' + Date.now()+ path.extname(file.originalname));
    }
});
var upload = multer({ storage: storage });

router.put('/user/profile/img/:email', upload.single('profileimg'), (req, res, next) => {
    // console.log(req.file);
    Users.findOneAndUpdate({ email: req.params.email }, req.file.filename).then(() => {
        Users.findOne({ email: req.params.email }).then((resp, err) => {
            res.send(resp);
        })
    })
})

Image is being saved in upload folder in my api but it's not saved in db.

The second parameter of the findOneAndUpdate function must be an object with the field to update and the value:

Users.findOneAndUpdate({ email: req.params.email }, { profileimg: req.file.filename }).then(...)

Yes you need to put the correct field name in the second parameter. I've edited.

We need more details then, there is probably an error somewhere else in your code.

You can do it like this code below:

router.put('/user/profile/img/:email', upload.single('profileimg'), async (req, res, next) => {
  try {
    // check your file is uploaded
    // check your field
    console.log(req.file);
    const result = await Users.findOneAndUpdate({ email: req.params.email }, {$set: { profileimage : req.file.filename}}, { returnOriginal: false})
    res.send(result)
  } catch(ex) {
    res.status(500).send(ex.message);
  }
})

Note: For this {$set: { profileimage : req.file.filename}}

profileimage : change with the field in your mongodb
req.file.filename: make sure to console.log(req.file) then, where the field you want to store, use it in here and change this example.

I hope it can help you.

Titus Sutio Fanpula Over a year ago

When you console.log(req.file), what the object you get?

Ambady Ajay Over a year ago

{ fieldname: 'profileimg', originalname: '1.png', encoding: '7bit', mimetype: 'image/png', destination: 'uploads/', filename: 'profileimg-1580208697681.png', path: 'uploads\\profileimg-1580208697681.png', size: 3368 }

the $set is unnecessary cus mongoose takes care of it internally.
