Currently, I am immersing myself in Node.js through the guidance of a book titled "Web Development with Nodejs and MongoDB." However, I have hit a roadblock when attempting to upload an image using Multer. The code snippet causing me trouble is as follows:
Behold, my Configure.js file:
var path = require('path'),
routes = require('./routes'),
exphbs = require('express-handlebars'),
express = require('express'),
bodyParser = require('body-parser'),
cookieParser = require('cookie-parser'),
morgan = require('morgan'),
methodOverride = require('method-override'),
errorHandler = require('errorhandler');
multer = require('multer');
moment = require('moment');
var upload = multer({ dest: './public/upload/temp' });
module.exports = function(app) {
app.use(morgan('dev'));
app.use(methodOverride());
app.use(cookieParser('some-secret-value-here'));
routes(app);
app.post('/public/upload/temp', upload.single('img'), function(req, res) {
//var form_description = req.body.description;
console.log(req.file.name);
// insert operations into database get placed here
res.redirect('/');
});
app.use('/public/', express.static(path.join(__dirname,
'../public')));
if ('development' === app.get('env')) {
app.use(errorHandler());
}
app.engine('handlebars', exphbs.create({
defaultLayout: 'main',
layoutsDir: app.get('views') + '/layouts',
partialsDir: app.get('views') + '/partials',
helpers: {
timeago: function(timestamp) {
return moment(timestamp).startOf('minute').fromNow();
}
}
}).engine);
return app;
};
Following that, we have the Handlebar (HTML) file:
...Lastly, here is the image.js Controller File
...During server execution and attempting to upload an image by clicking the Upload Image button, I encounter the error:
Cannot read property 'path' of undefined
...I have exhaustively scoured the internet for solutions but to no avail! If anyone can provide assistance, it would be greatly appreciated!
