This is the conclusion of Ramaze by Example, a tutorial on web development. In Part 11: Validation and Error Handling, we added a custom error page and handlers for common user errors.

Having gone through this tutorial, you should now know about:

1. installing Ramaze
2. setting up a database schema
3. creating a base Ruby file for an application
4. models and using them to interface with the database
5. views
6. interpolating data into views
7. controllers
8. the relationship between requests, controller methods and views
9. how to implement basic CRUD operations
10. handling HTTP POSTed data
11. using layouts for consistent page appearance
12. where Ramaze gets static files from
13. basic built-in Ramaze methods and helpers, like the link, flash and redirect helpers
14. handling errors and displaying error messages

Armed with this information, you should be well-equipped to build a small web application of your own right now.

Learning More

This tutorial has covered a fair bit, but there are actually considerably more features and functions of Ramaze that I didn’t discuss. Some of these are:

• partials or elements
• session variables
• aspects
• testing
• routing
• deployment
• form helpers and scaffolding generators
• cooperation with Javascript, AJAX
• … and more!

I hope to cover some of these things in future blog posts. You can subscribe to my blog via RSS or by email.

Here are some resources you can reference to learn more about Ramaze:

• ramaze.net, the official website
• The RubyConf 2008 Ramaze presentation by Luc Castera
• The original todolist tutorial by manveru
• The Ramaze codebase – no really, you can learn a lot from it, and the code is easy to read, and very well commented
• The examples/ dir of the Ramaze codebase
• ramaze-book, a partially complete e-book written by manveru
• The codebase of sociar, an open source social networking platform. Sociar is pretty much the de facto, comprehensive Ramaze example, written by manveru himself.
• The #ramaze IRC channel and mailing list

Get Started!

# gem install ramaze

require 'ramaze'
class MainController < Ramaze::Controller
  def index
    "Hello, world!"
  end
end
Ramaze.start
