Rails web framework is a full-stack framework for developing database-backed web applications according to the Model-View-Control pattern.

From the Ajax in the view, to the request and response in the controller, to the domain model wrapping the database, Rails gives you a pure-Ruby development environment. To go live, all you need to add is a database and a web server.

Everyone from startups to non-profits to enterprise organizations are using Rails. Rails is all about infrastructure so its a great fit for practically any type of web application Be it software for collaboration, community, e-commerce, content management, statistics, management, you name it.

Rails works with a wealth of web servers and databases. For web server, we recommend Apache or lighttpd running either FastCGI or SCGI. For database, you can use MySQL, PostgreSQL, SQLite, Oracle, SQL Server, DB2, or Firebird. Just about any operating system will do, but we recommend a nix-based one for deployment.

Creating a weblog in 15 minutes

In 15 minutes, we go from scratch to complete weblog engine: with comments and an administrative interface. But since the actual application only took 58 lines to complete, we also have time left over to do unit testing, examine the logs, and play around with the domain model.

Putting Flickr on Rails

Ruby on Rails is not just for playing with your local database, its for taking on the web. So in 5 minutes, we create a web-based search engine for Flickr using their public API with all the fades and glamour of Ajax. Hows that for a low-tech alternative to something fancy like Flash.

Evolving your database schema without a sweat

Before you know it, youll have data that you care about in your application. Which makes adding, removing, or changing the schema an error-prone, time-consuming, and frustrating process. That is, unless youre using Ruby on Rails. In 20 minutes, youll learn all about how database migrations can make your schema as flexible as your code with no fear of data loss.

Rails Live CD project was born on Ezra Zygmuntowicz blog and realized with help from Brian Ketelsen. Rails Live CD is based on PCLinuxOS which is a great Linux distribution for creating LiveCDs. More information at PCLinusOS.com
To use it, just download, burn and reboot! Or if you have a virtualization or emulation engine like Qemu, Parallels or VMWare it is even easier.
Many people are curious about Ruby on Rails but dont want to go through the pain of installing it locally. The Rails Live CD solves this problem by allowing you to have a fully operating Ruby on Rails development environment without even touching your hard drive!
Others are interested in developing Ruby on Rails applications in Linux but dont have the skills or the patience to do the installation and compiling required to get Ruby on Rails running on a typical Linux installation.
Rails Live CD allows you to install directly to your hard drive and walks you through the process. No compiling or ./configure ./make ./make install dancing required.

Rails History Plugin is a Ruby on Rails plugin that stores user actions (i.e. URLs that the user has recently visited).
It avoids storage of POST and AJAX requests, and it provides a manual way to specify which actions not to store.
Installation:
Unpack into the vendor/plugin and that should be it.
Usage:
In your app/controllers/application_controller.rb, add a history line like this:
class ApplicationController < ActionController::Base
history :default => "http://default.url.com/",
:max => 10
end
The history function accepts a hash of options
:default, the default URL to redirect
:max, the maximum locations to remember (five by defaults).
None of the parameters are required. If somebody knows of a better way to obtain the default URL, he is welcomed to tell me how.
You can use the method history_skip in your controller if you want to avoid certain location to be stored in the history. By default, action resulting from a POST, PUT, DELETE request or an Ajax request are not stored in the history.
class FooController < ApplicationController
history_skip :action_to_skip
def action_to_skip
# I will not be stored in the history
end
end
In your actions, you can then use the following methods:
last_location: returns the last visited location, can be used with one numeric argument precising how many locations to go back in the history (1 by default),
peek_last_location: like last_location but dont remove it from the history,
redirect_back: redirect the user to the last location in history, it takes the same arguments as last_location,
store_location(force = false): stores the current location in the history, set force parameter to true to store location even if it would be skipped.
Note that if you want to use the plugin to create a "back" link on a page, you must go back two times. For example, using this controller
class HistoryController < ApplicationController
def foo
end
def bar
end
def back
redirect_back(2)
end
end
Ill try to explain clearly why. Lets say that in your bar view, you create a back link wich links to the back action. Now a user visits foo then bar. What you want is your user being redirected to foo when clicking your "back" link. Now your user hits the link. The controller will call the back action. From its point of view, you are in the back action so going back one time would take you to the bar action.
Enhancements:
- This release fixes a bug where a user variable was stored in a class variable instead of a session one, so a user going back would make another one skip a page in its history.
- The plugin no longer stores PUT and DELETE requests.
- A peek_last_location method was added to look at the history without modifying it, and a "force" parameter was added to the store_location method to force storing of a location even if it would normally be skipped.

Ruby on Rails SubList Plugin makes it easy to have dynamic lists of related models on a single editing page.

The plugin is designed for models with one or more has_many relationship with other models.

By using AJAX for adding and removing "sub-forms" one can present the user with a single edit page that creates/edits the parent model as well as all of the children.

Usage:

Place the sub_list directory in the vendor/plugins dir of your application.

In the controller which you wish to have a sub list displayed, add the following lines:

include UIEnhancements::SubList
helper :SubList

sub_list SubModel, parent do |new_research_student|
#Place any construction (ie. defaults) required here
end

Replace SubModel with the class name of the sub model you wish to make available.

Replace parent with the parent object.

For instance, if you wish to have a Person controller that has a sub list of Dogs for each person, the sub model would be Dog and the parent would be person. It is expected that @person would exist and that it contains a has_many relationship named dogs.

parabola project is a browser-based news feed aggregator.
parabola is written using Ruby on Rails and uses the FeedTools module for all feed parsing.
Enhancements:
- Ruby 1.8.2
- Rails 1.0+
- MySQL 4.1+
- Rubygems
- FeedTools 0.2.18+
- acts_as_taggable 1.0.4+
Installation:
Database
Create a MySQL database called parabola_p. Add a user with proper access to it:
$ mysql -u root -p
mysql> CREATE DATABASE parabola_p;
mysql> GRANT ALL PRIVILEGES ON parabola_p.* TO parabola@localhost IDENTIFIED BY parabola;
Now initialize the database with the schema:
$ mysql -u parabola -p parabola_p < db/schema.mysql.sql
If you use a different username than parabola and/or a different password than parabola you should subsequently edit config/database.yml to reflect that.
Now test by running the built-in webserver:
$ ./script/server -e production
If you can connect to http://localhost:3000/ and see a login form you are up and running.
Updating Feeds
A script called updatefeeds.rb takes care of downloading feeds and updating the database according to your settings. It is located in the support/ directory.
You can run this manually but this gets rather boring after a while. Better to add it to whatever scheduling program you are using such as cron and have it run maybe once an hour. The script just needs to be pointed to the root of where you extracted parabola. Lets say its in/var/htdocs/parabola/. You would then run it as such:
$ updatefeeds.rb -r /var/htdocs/parabola/
Make sure the entire public/cache/ is writable by the user which the script runs as. Below this directory favicons are stored.
Each feed is at maximum checked once per hour but you can give the script the -f option (for force) to force it to check each feed every time the script is run.
Using
If you use the special tag :nfp: on a feed its articles will not appear on the frontpage.
Enhancements:
- This release deletes articles older than the keep days setting for a feed, and articles with dates in the future are now set to current date and time.
- It shows date on each article in the articles view, and a New feed menu item has been added to be able to quickly add new feeds.
- There are several major bugfixes.
