1. In Listing 9-9 the Models Employee and Team are not Imported. I added
   require('../models/employee');
   require('../models/team');
   to make it work.

2. After substituting the script as stated, the http://localhost/employees hangs forever.

I'm having trouble with chapter 6, after the initial setup of the server within index.js I attempt to go to 127.0.0.1:1337/ within my browser and get the following error in my terminal;

TypeError: Cannot read property 'toUpperCase' of undefined
at Server. (/Users/LewisEccles/Documents/Git projects/human-resources/index.js:8:26)
at emitTwo (events.js:106:13)
at Server.emit (events.js:191:7)
at HTTPParser.parserOnIncoming [as onIncoming] (_http_server.js:543:12)
at HTTPParser.parserOnHeadersComplete (_http_common.js:105:23)

Looking at the error its obvious its on line 8 in my code which is;

req.method = req.method.toUpperCase();

however looking at the index.js file here on github, it is an exact match, I've even copied and pasted it over my code however it still doesn't work.

Due to the error, I get an error in chrome saying that 127.0.0.1 refused to connect.

Does anyone know how I can fix this error, or provide me some guidance on where to look for an answer?

My full index.js is below in case anyone wants to see it there.

Thanks

var http = require('http');

http.createServer(function (res,req) {
  //A parsed url to work with in case there are parameters
  var _url;

  //In case the client uses lower case for methods
  req.method = req.method.toUpperCase();

  console.log(req.method + ' ' + req.url);

  if (req.method !== 'GET') {
    res.writeHead(501, {
      'Content-Type': 'text/plain'
    });

    return res.end(req.method + ' is not implemented by this server');
  }

  if (_url = /^\/employees$/i.exec(req.url)) {
    //return a list of employees

    res.writeHead(200);
    return res.end('employee list');

  } else if (_url = /^\/employees\/(\d+)$/i.exec(req.url)) {

    //find employee by id in the route
    res.writeHead(200);
    return res.end('a single employee');

  } else {

    //try to send the static file
    res.writeHead(200);
    return res.end('static file maybe');
  }

}).listen(1337, '127.0.01');

console.log('Sever Running at http://127.0.0.1:1337/');

I ran this and when I checked the employees data using mongodb the team attribute was null;

To fix this I needed change 2 functions:

1. addTeams

if (error) {
console.error('Error: ' + error);
} else {
data.team_id = team1._id;
}

changed to

    if (error) {
        console.error('Error: ' + error);
    } else {
        team1.forEach(function (team1a) {
            data.teams.forEach(function (team) {
                if (team.name === team1a.name) {
                    team.team_id = team1a._id;
                }
            });
        });
    }

2. updateEmployeeTeams

Employee.update({}, {
team: data.team_id
}, {

changed to

Employee.update({}, {
    team: team.team_id
}, {

In both insertTeams and insertEmployees :

When the array is passed to create for either Team or Employee, later on, both devops and acct are undefined and pd is an array.

I had to remove the square brackets when create is called for both Team and Employee for later code to work correctly.

You should replace the last lines of index.js

...
 } else {
    // Try to send static files
    res.writeHead(200);
    res.end('static file maybe');
  }

with

...
 } else { 
    staticFile(req.url,res); 
  }

The program as is will continue to respond with 'static file maybe' to every request not intercepted by the preceding routing tests.
