Ruby on Rails 1.0: What's New, Release History & Support Lifecycle

What Is New in Ruby on Rails 1.0

How does Rails 1.0 simplify building CRUD interfaces?

Rails 1.0 introduces scaffolding that automatically generates a full CRUD stack for a given model.

Running the scaffold generator creates the model, migration, controller, views, and test files in one command:

rails generate scaffold Post title:string body:text

In practice this cuts weeks of boilerplate work down to minutes, letting teams focus on business logic instead of repetitive code.

What new email capabilities does Rails 1.0 provide?

Rails 1.0 adds ActionMailer, a built-in framework for composing and delivering email from your application.

A typical mailer class looks like this:

class NotificationMailer < ActionMailer::Base
  def welcome(user)
    @user = user
    mail(to: @user.email, subject: "Welcome!")
  end
end

Watch out for the need to configure your SMTP settings in config/environment.rb before sending mail in production.

How has testing been integrated into Rails 1.0?

Rails 1.0 ships with a built-in testing harness that ties Test::Unit directly into the framework.

Every scaffold now includes unit, functional, and integration test files, and you can run the full suite with:

rake test

This matters if you want zero-configuration test runs; fixtures are loaded automatically and controller tests have helper methods like get and post.

What improvements were made to routing and controller handling in Rails 1.0?

Rails 1.0 refines the routing DSL and streamlines controller callbacks for clearer request flow.

• Routes are defined in config/routes.rb using a map object (e.g., map.connect ':controller/:action/:id').
• Named routes and resource-like routes are introduced, reducing manual URL construction.
• Before/after filters are now more consistent, allowing before_filter :authenticate at the controller level.

Most teams will see fewer routing bugs and easier URL generation with the new helpers.

Are there any breaking changes or deprecations to watch for when upgrading to Rails 1.0?

Rails 1.0 deprecates the old plugin initialization style, encouraging use of generators for extending the framework.

If your application relies on Rails::Plugin hooks, replace them with a generator-based approach or move the code into lib/ and require it manually.

Watch out for missing script/generate commands if you still use the pre-1.0 plugin scaffolding.
