Play-by-Play: Rails Setup

I still don’t have an official name for this project, so I’ll call it “bakery” in the interim.

rails bakery
git add bakery
git commit -a -m "Basic Rails install"
rails server

This is new: there’s a single execution point for rails tasks. It’s nice to not have to type script/... all the time

Fire up http://0.0.0.0:3000/ and see that it’s working.

Gem Updates

Update haml/sass:

sudo gem update haml

Add “gem haml” to Gemfile (another new feature).

Update Ryan Bates’ Nifty Generators. They’re nifty. Especially when generating.

sudo gem install nifty-generators

Add “gem nifty-generators” to the Gemfile.

Also update autotest and shoulda

Hello World

Time to get a Hello World going. It’s not working until I see Hello World.

First, unpack the gems. How do I do that again?

rake -T gem
/Users/craig/Documents/SoftCraft/projects/bakery/rails/bakery/db/schema.rb doesn't exist yet. Run "rake db:migrate" to create it then try again. If you do not intend to use a database, you should instead alter /Users/craig/Documents/SoftCraft/projects/bakery/rails/bakery/config/boot.rb to limit the frameworks that will be loaded

Fair enough.

rake db:migrate
(in /Users/craig/Documents/SoftCraft/projects/bakery/rails/bakery)

rake -T gem
(in /Users/craig/Documents/SoftCraft/projects/bakery/rails/bakery)
rake rails:freeze:gems  # The rails:freeze:gems is deprecated, please use bundle install instead

More Rails 3 changes. Looks like freezing isn’t necessary any more. That’s good; I never liked it anyway.

Now, I need a “Hello World” page. That means I need a HomeController for the root route.

rails generate controller Home

Now I need a view. Since Home is a singleton controller, that’s the show view. Whip up Add views/home/show.haml and dump in Hello World.

Now I need a route. In the new Rails 3 routing DSL that’s done by:

root :to => "home#show"

Lastly, I need to delete public/index.html.

Hit localhost:3000 and it works!

Shoulda

Looks like Shoulda isn’t Rails 3 compatible yet.

DEPRECATION WARNING: RAILS_ROOT is deprecated! Use Rails.root instead. (called from join at /Users/craig/.bundle/ruby/1.8/bundler/gems/shoulda-b8b6cad61981d47356de06c2a5586e281938c94e-rails3/lib/shoulda/autoload_macros.rb:40)

I go to report this bug. Of course, when I register with RailsPlugins, I get this:

We are sorry to say that something in our code went bang!

Screw it, I’ll avoid Shoulda in the interim. Instead, I’ll create a regular Test::Unit controller test.
