User Signup

We'll need to...

1. Double-check our signup form
2. Create a POST route for receiving the new user's data
3. Create a new user within the POST route
4. Redirect to either the home page or signup page, depending on if there's an error

Double-check the signup form

Take a look at the current signup form and GET /auth/signup route. Some things you'll want to know about:

• The signup form's action
• The signup form's data
• The signup form's route
• Can we access the signup form?

Before continuing, verify that this test is passing

Auth Controller - GET /auth/signup - should return a 200 response

Creating a POST route

To receive the user's data, let's create a signup route.

controllers/auth.js

router.post('/signup', function(req, res) {
  // try sending back the form data
  res.send(req.body);
});

Verify that this works. While spitting back form data verifies this route's functionality, we don't really want this. We want to implement the following logic:

• Take the user's data from req.body
• Find or create a new user, based on the email address provided
  • If the user wasn't created, the email address must already exist. Let's redirect back to the signup form so the user can fix this error.
  • If the user was created, we're successful! Redirect back to the home page
  • If an error occurs, it'll most likely be due to a validation error. Let's redirect back to the signup form so the user can fix this error.

controllers/auth.js

// at the very top, include the database models
var User = require('../models/user');

router.post('/signup', function(req, res) {
  User.create({
    email: req.body.email,
    name: req.body.name,
    password: req.body.password
  }, function(err, createdUser) {
    if(err){
      console.log('An error occurred: ' + err);
      res.redirect('/auth/signup');
    } else {
      res.redirect('/');
    }
  });
});

This should pass the following tests

Auth Controller - POST /auth/signup - should redirect to / on success

Auth Controller - POST /auth/signup - should redirect to /auth/signup on failure
