I also created a scaffold for CloudEdit on ScaffoldHub, which will setup the code from CloudEdit inside your own Rails 3 app with a single command:

I wonвЂ™t repeat everything from JamesвЂ™s tutorial here since he does a fantastic job of describing the code details.

James posted his Rails 2.3.8 app on github, so you can just download the code and try it out yourself. Backbone was also designed with a Rails backend in mind, and is easy to connect to a server application using JSON to transfer data back and forth.ДЄside from the basic documentation, thereвЂ™s a great Backbone/Rails tutorial out there by James Yu James walks you step by step through creating a simple Ajax/Backbone app that allows you to create and edit documents in a single page: It also has an object called a вЂњcollectionвЂќ which manages a list of models. Just like in Rails, you use models to represent data, views to render the data, and controllers to coordinate between the two. Backbone was written by and is still maintained by DocumentCloud. js files in the public/javascripts folder, and any custom javascript is all combined together in one large вЂњapplication.jsвЂќ file:Д«ackbone.js is a great way to organize your client Javascript code into the same MVC (model, view, controller) pattern that your Rails server application uses. In a typical Rails 3.0 project, all of the vendor Javascript code (e.g.

Instead, the biggest problem I faced using Rails 3.0 and earlier versions was how to organize my Javascript code.

In most of my Rails projects the performance impact of having many small files was small. However, in my opinion performance is not actually the biggest problem here. The Rails 3.1 asset pipeline, which IвЂ™ll get to in a moment, solves this problem in Rails 3.1 by combining all of the static files together into a single download request. The biggest problem with this was that each static file, whether an image, CSS stylesheet or Javascript code file, required a separate HTTP request to the server. Javascript code was considered just another type of static web asset file, like stylesheets and images, and was simply downloaded to the client browser by Apache or Nginx, without the Rails framework getting involved at all. Ancient history: 2010 and beforeД«efore the asset pipeline was introduced in the Rails 3.1 beta this year - as I write this the latest version of Rails is 3.1.0.rc4 - all of the javascript code in a Rails web site was typically stored under the вЂњpublicвЂќ folder, along with other static content: at least until the Rails community agrees on a single convention. Hopefully this will help you decide how to organize your Javascript code files.

Today IвЂ™m going to show off two interesting Rails projects and focus on how their developers have chosen to organize their Javascript code files. All of this lead me to ask myself: where should I put my Javascript code in a Rails 3.1 app? The answer is not at all obvious! And recently there have been a lot of exciting new ideas and technologies in the Javascript space, as well as some innovative and dramatic changes to Rails itself with 3.1 coming out soon. Well organized code directories leads to well organized code!Д«ut these days most modern web sites include a large amount of Javascript code, not only server-side web page generation. I think it actually effects the way you think about code. The way you save and organizing your code files is not simply a convenience. When you start a new project all of this is setup for you, and if youвЂ™re a new developer assigned to an existing Rails project you know where to look for things. пїјEvery Rails developer knows to look in вЂњapp/modelsвЂќ for the model classes, вЂњapp/controllersвЂќ for the controller classes, etc. One of the best things about the Rails framework is that each project looks the same:
