DHH Keynote at RailsConf Europe 2006

9:30 David Black, Welcome

9:40 DHH * Slides in textmate

• Rails 1.2 as beta gem today
• Dependency changes
• Big change in routing - should mean “the incident” won’t happen again
• Last major 1.x release

• Lots of deprecations - ready for 2.0

• SimplyRestful

• Full set of HTTP verbs
• Be good web citizens
• The big change is to allow us to focus on bigger issues
• Conventions for controllers:

    map.resources :posts do |p|
      p.resources :comments
    end

• New scaffolder (not shiny like Streamline, still hideously ugly by design) supplement not a replacement for old scaffold
  • $ ./script/generate resources_scaffold posts
  • produces a controller, a model and a migration for the model

    # GET /posts
    def index
    
    # GET /posts/1
    def show
    
    # GET /posts/1;edit
    def edit
    
    # POST /posts
    def create
    
    # PUT /posts/1
    def update
    
    # DELETE /posts/1
    def destroy

• out of the box scaffoldding will work with xml as well as html, just stick an .xml on the url
• Posts.xml returns <posts><post>…</post><post>…</post></posts> [Shame it’s not RSS/Atom :-(]
• ActiveResource builds on top of HTTP like ActiveRecord builds on DB. Class is singular url is plural. All your models are exposed as a RESTful API.
• Use .xml on POSTS to, use responds_to.

• ActiveResource is not shipping with 1.2, available as an external gem, it may ship with 2.0. Using it at CD Baby.

• SimplyHelpful - views by convention, available as a plugin now

    <div class="post" id="post_45">...

becomes

    <% div_for(@post) do %>...

and similarly for page[...], partials, form_for etc.

* Will be in Rails 2.0 * New functionality should be developed as a plugin first, rather than patches against the trunk.
