Chapter 2 Tests failing with TypeError: Cannot call method 'drop' of undefined

Hey

Apologies for not responding sooner; I have been up against it on support this week :) Lets see if we can get you up and running.

Seems to be working ok for me; it looks like the collection does not exist; as mongoose.connection.collections['projects'] is returning undefined..

You shouldn't be seeing this error if mongo is running correctly.

Can you run the following; from terminal:

mongo
use vision
show collections

You could also install robomongo; and have a look around; make sure the vision project exists.

Can you also check your db connection; you should have 'mongodb://localhost/vision' in configuration. You could try changing this to 127.0.0.1; you may have an issue with localhost.

Also check which process is using that port:

lsof -i:27017

Let me know how you get on.

I'm running Linux Mint 16 with Node v0.10.25, and installed Mongodb using the built-in software manager. I downloaded RoboMongo and am able to connect and execute functions against Mongo. The database "vision" exists, and I can show collections.

I used RoboMongo to create the "projects" collection just to see if the beforeEach method would drop a collection that previously existed, but I'm still getting the same error. Switching the config to use 127.0.0.1 also results in the same error.

If I run:

moch test

Against Chapter 2 from the Github repo, it works as expected. I'm sure it's something I've done, but I'm not exactly sure what to look for. I'm primarily a Python developer and just getting my feet wet with the Node ecosystem.

A triple-check inspection of my code isn't turning up any differences in structure or syntax up to page 24 of the book. I'm more than happy to create a public repo and drop my code in it for you. Thanks for helping!

That would be great.

Hey

If you look at page 26 you will see you are missing the following from your ./lib/express.js file.

The models are assigned to mongoose from inside ../routes/project in the accompanying service.

Hope this resolves things; let us know.

var express = require('express')
, http = require('http')
, config = require('../configuration')
, db = require('../db')
, heartbeat = require('../routes/heartbeat')
, project = require('../routes/project')
, notFound = require('../middleware/notFound')
, app = express();

app.use(express.bodyParser());
app.set('port', config.get('express:port'));
app.use(express.logger({ immediate: true, format: 'dev' }));
app.get('/heartbeat', heartbeat.index);
app.post('/project', project.post);
app.use(notFound.index);
http.createServer(app).listen(app.get('port'));
module.exports = app;

Thanks Andrew. Looks like I was just missing the post route, and I was premature in running my tests.
