My Note from "The Intro to Rails Screencast I Wish I Had"

I found that The Intro to Rails Screencast I Wish I Had is very good in demostrating some tricks that make Rails different to other web development frameworks.

Below are notes from my 2nd time watching this screencast. What I note are things that I've never known before or I can't really remember the way to use it.

• Add -T in rails new to prevent rails from generating Test::Unit
• Gems
• turn (Pretty printing for test results)
• guard-rspec (Autotest)
• growl_notify
• rb-fsevent
• launchy
• save_and_open_page (use along with Capybara statements)
• Guard
• guard init rspec
• guard (start guard)
• RSpec integration test
• rails g integration_test {name}
• Routes
• rake routes
• resources (auto routes)
• Capybara (route_name comes from first column of rake route)
• visit {route_name}_path
• page.should have_content {string}
• fill_in {id/name/label}, :with => {string}
• click_button {id/name/label}
• current_path.should == {route_name}_path
• find_field('').value
• ActiveModel
• {Model}.create {value}
• {model_instance}.update_attributes {fields hash}
• ERB
• form_for {object} do | f |
• f.label :{name}
• f.text_field :{name}
• f.submit
• render '{partial view(No _)}'  <- partial view file name must prefix with _ 
• flash.each do | name, message | (come from params passed with redirect_to)
• Controller
• render :text => params.inspect
• redirect_to :back (previous page)
• (redirect_to) {:notice | :alert} => {string} (will be available in flash)
