/* The API controller
Exports 3 methods:
* post - Creates a new thread
* list - Returns a list of threads
* show - Displays a thread and its posts
var Thread = require('../models/thread.js');
var Post = require('../models/post.js'); = function(req, res) {
new Thread({title: req.body.title, author:}).save();
exports.list = function(req, res) {
Thread.find(function(err, threads) {
// first locates a thread by title, then locates the replies by thread ID. = (function(req, res) {
Thread.findOne({title: req.params.title}, function(error, thread) {
var posts = Post.find({thread: thread._id}, function(error, posts) {
res.send([{thread: thread, posts: posts}]);
// The main application script, ties everything together.
var express = require('express');
var mongoose = require('mongoose');
var app = module.exports = express.createServer();
// connect to Mongo when the app initializes
// set up the RESTful API, handler methods are defined in api.js
var api = require('./controllers/api.js');'/thread',;
