The system is facing difficulty in accessing the property 'user_first_name' as it is currently undefined

Question

The system is facing difficulty in accessing the property 'user_first_name' as it is currently undefined

I'm having trouble registering a user with expressjs/mongoose as I keep receiving the error:

TypeError: Cannot read property 'user_first_name' of undefined
at C:\Quiz webPolitica\server.js:20:24
at Layer.handle [as handle_request] (C:\Quiz webPolitica\node_modules\express\lib\router\layer.js:95:5)
...

I've been debugging for hours and searching for solutions, but haven't made any progress. Any assistance would be greatly appreciated. Here's my code:

server.js

...

index.html

...

Additionally, I need help redirecting to a new page after registration is complete. My current approach "app.use(express.static(__dirname + '/user_profile.html'));" seems incorrect. Can anyone provide guidance on how to achieve this properly?

Answer №1

When dealing with req.body in Express, middleware is responsible for converting the request data to JSON before it can be accessed by custom code.

To ensure this conversion process happens smoothly, consider installing and using body-parser in your project (npm install body-parser). You should add this before any app.post routes:

var bodyParser = require('body-parser');
app.use(bodyParser.json());

By implementing this setup, the incoming requests to your server will be parsed and organized into a JSON object accessible through req.body.

For redirecting purposes, simply include a straightforward res.redirect('/newPage') at the end of a route to direct users to a new page.

The error message indicates that the body in req.body is empty. After some research, I came across a helpful response on Stack Overflow. The solution suggests that:

You need to use a method to parse the request's body data.

This involves using a tool like bodyParser

However, it's worth noting, as @andrea.spot mentions, that starting from Express4 (which I assume you are using), the BodyParser middleware must be installed separately.

According to @Jay's recommendation for Express4, you should configure express as follows:

var bodyParser = require('body-parser');
app.use(bodyParser.json());

Furthermore, as @Jay highlights, you can install this package by running:

npm install body-parser --save
