Chart in Rails – RailsCarma Blog. We have been working on a project that deals with server data where charts are worth a thousand words.
I always get requests for various charts and in the past I’ve used Gruff to produce them. Gruff is a great library and the results look good too! However, recently I’ve have had more demanding requirements to provide more dynamic behaviour on the charts. Users wanted to be able to interact with the charts in various ways and drill down to gather more information. I looked at the alternatives to Gruff and decided to go with XML/SWF charts. In this article, I would like to throw some light on various charts that are available for rails like Gruff, Google charts, Ziya charts, Open Flash charts and Fusion charts. I am currently using Open Flash charts for the current project.
Gruff charts: Gruff is a Ruby library for generating attractive and powerful graphs, useful for web applications, print media and many others. Snapshot Rendering.

Behavior Driven Development describes a cycle of interactions with well defined outputs, resulting in the delivery of working, tested software that matters.
With BDD, you create executable specifications, not tests. You want to look at what your code does, not the internals of how it does it. This method of development is mainly about visualizing goals and aims at writing tests BEFORE writing the production code rather than testing all of the application code after its development. If you focus on testing your classes, then the structure of your test code mirrors the structure of your production code. What happens when you re-factor and you change that structure? When you re-factor, the behavior of your application doesn’t change. Welcome Rails 3.0 – RailsCarma Blog.

Red_items.exists? Deploying Rails Application using Capistrano and Phusion Passenger. Deploying a rails application onto the servers is a complicated task when performed manually, since it needs us to login to the servers, upload the code from the local system every time and maintain the backup of the updates if we want to revert.
The process consumes a lot of time and we need to stop, start and restart the application servers every time we need to update. This task can be simplified using these two deployment tools i.e Capistrano and Phusion Passenger (also called as “mod_rails”). The installation procedure for both the tools are quite the same, since both tools are installed as the Rails gems. That is the specialty of Rails framework that it has all the required tools to operate build as gems. But the difference is that Capistrano helps to upload the code and deploy whereas Phusion Passenger is an Apache module which helps us to deploy a rails application on Apache a breeze. The installation of the Tools are as shown below : Capistrano Deployment With Subversion - RailsCarma Blog.
