LazyBoy Object Modeller

Oh my word... What have you done?

My experiments into what it takes to create a object mapper for Couchdb. This has been something I've been thinking about for a while and whether its a viable option.

Currently its purely fun research. I've been reading through mongoose and couch-ar as imspiration.

#How do I use this thing?

Below is a quick cheatsheet but the docs can be found http://garrensmith.com/LazyBoy

Defining a model

var Model = require('LazyBoy');

Model.define('User', {
  name: String
  surname: {type: String, default: "Rambo"}

Creating and saving a model

var user = Model.create('User', {name: "John", surname: "Rambo"});

user.save(function (err, saved_user) {
    // .. do some other stuff here

Finding a model

Finding by Id

var user_id = "123456";

var User = Model('User');
User.find(user_id, function (err, user) {
    // .. do something with the user

Find all

Will return an array of all documents that fit the criteria

var User = Model('User');
User.all(function (err, users) {
    // .. do something with the user

Find by criteria

Will return an array of all documents that fit the criteria

var User = Model('User');
User.where(name,"Ben", function (err, users) {
    // .. do something with the user

LazyBoy uses Coloured logger under the covers and uses the same log levels
