A Backbone.js demo app (Sinatra Backend)

Oct 16 2010

Updates

04/10/2011 - Updated application.js and application.rb thanks to @rebo's comments

In this article, I will walk through some simple steps to get a [demo app][2] up and running with [Backbone.js][3] and [Sinatra][4] on [Heroku][5].

Dear Rubyists,

I just lost a contract because of my code in a Rails project.

The specific code in question is related to a "posting a comment" feature. Here are the details:

In this project, "posting a comment" does not simply entail inserting a row into the database. It involves a procedure to yes, insert a row, but also detect its language, check for spam, send emails, and "share" it to Twitter and Facebook. I believe this algorithm should be encapsulated. I do not believe it belongs in a controller or a model. I do not believe Active Record callbacks should be used.

The "senior developer", whom is the stake holder's right hand man, said this:

	# MongoMapper "embedded document delete" plugin
	# By Peter Cooper
	#
	# Got embedded documents you want to delete? You can delete them as if the
	# embedded document collection were an array, but then there's no way to get
	# a callback (as far as I could tell). This plugin gives you a call back
	# (if you want it) and gives a nicer syntax to deleting embedded docs.
	#
	# Example:
	#

	def is_ajax_request?
	if respond_to? :content_type
	if request.xhr?
	true
	else
	false
	end
	else
	false
	end

	# /usr/bin/env ruby
