This page is incomplete

At the moment, it only represents a first pass at sections 4-13.

Once complete, this page is intended to shows changes in “Rails 3.0” that affect the sample code in Agile Web Development with Rails, Edition 3. As page numbers in the paper and PDF copies differ, this information is organized first by section number, then it lists both page numbers, paper copy first.

Meanwhile, a “live” status: of a suitably modified Edition 3 scenario (as well as a developing Edition 4 scenario) under various versions of Rails and Ruby is available online. Note that page is based on pulling Rails from git (and for 1.8.8 and 1.9.2, Ruby from svn) so it will often reflect failures that will not make it out to beta.

4.1 Creating a New Application

  • Page 36/45 : After cd demo and before ruby script/server, edit config/routes.rb, and uncomment the following line:
    • match ':controller(/:action(/:id(.:format)))'

6.3 Adding a Missing Column

  • Page 73/81: the h’s are no longer present in the template.
  • Page 74/82: instead of editing new.html.erb and edit.html.erb files, edit _form.html.erb. Instead of a <p> tag, you will see <div class="field">
  • Page 75/83: the h’s are no longer present in the template.
  • Page 76/84: instead of deleting the h, add the word raw.

7.1 Creating the Catalog Listing

  • Page 87/95 : Edit config/routes.rb, and uncomment the following line, and then restart the server:
    • match ':controller(/:action(/:id(.:format)))'
  • Page 89/97 : remove the h before product.title, add raw before product.description

8.1 Sessions

  • Page 99/107: the line to uncomment in environment.rb now looks as follows:
    • ActionController::Base.session_store = :active_record_store
  • Page 100/107: The setup is now done in config/initializers/session_store.rb
  • Page 100/108: there no longer is a need to uncomment out the :secret parameter in application.rb (which is now named application_controller.rb)

11.1 Iteration F1: Adding Users

  • Page 158/164: The preferred way to order the users returned in the index is now:
    • @users = User.order(:name)
  • Page 159/165: Instead of a separate line assigning flash[:notice], there now is a :notice parameter on the format.html call.

11.3 Iteration F3: Limiting Access

  • Page 166/172: application.rb is now application_controller.rb

11.4 Iteration F4: A Sidebar, More Administration

  • Page 168/174: application.rb is now application_controller.rb

13.1 Iteration I1: Enabling Translation

  • Page 187/193: omit the setting of LOCALES_DIRECTORY (alternately, use Rails.root instead of RAILS_ROOT).
  • Page 190/196: application.rb is now application_controller.rb
  • Page 199/205: delete the line containing activerecord: from config/locales/es.yml, and unindent the definition of errors.template and errors.messages
  • Page 200/205: error messages are double escaped. Bug 2409

14.3 Functional Testing of Controllers

  • Page 221/226: application.rb is now application_controller.rb

16.2 Enumerations and Arrays

  • Page 273/277: :skip_last_comma has been deprecated. Use :last_word_connector instead.

16.9 Unicode support

  • Page 283/287: name.chars.reverse is now name.mb_chars.reverse
  • Page 284/288: person.name.chars is now person.name.mb_chars (twice on this page)

21.2 Routing Requests

  • Page 424/428: add the following as the first action after starting script/console:
    • ActionController::Base.session_store = nil
  • Page 431/436: some of these examples return /blog/show_date?... instead, but only with Rails version 2.3.4. Bug 3198

21.4 Testing Routing

  • Page 455/459: the excerpt in the book doesn’t show it, but if you download routing_conditions_test.rb and wish to execute it, you will need to add require "config/routes_with_conditions.rb" to the beginning of config/routes.rb. After this is done, you can remove the setup method entirely from RoutingTest as it is unnecessary.

23.11 Adding New Templating Systems

  • Page 557/560: the render method in RDocTemplate now needs to have two parameters, thus:
    • def render(template, local_assigns = {})
  • Page 558/560: application.rb is now application_controller.rb
  • Page 559/562: the same change needs to be made to the render function in EvalTemplate too
  • Page 559/562: remove call to :evaluate_assigns
  • Page 559/563: the line that starts with template.locals.each now looks as follows:
    • local_assigns.each do |key, value|

25.3 Testing E-mail

26.2 Show Me the Code!

  • Page 626/628 : After cd depot_client, edit config/routes.rb, and uncomment the following line:
    • match ':controller(/:action(/:id(.:format)))'
  • Page 628/630: application.rb is now application_controller.rb

26.3 Relationships and Collections

  • Page 630/632: the config/routes.rb line now needs to look like this:
    • resources(:orders) { resources :line_items }
