template_umur_demo_blog.rb

# Usage example: rails new demo_blog -m template_umur_demo_blog.rb
# 2 points demonstrated
# - Templates are powerful. You can create even a working application
# - Ruby on Rails is very DRY. Code reads as if it's design

# Required gems
gem 'therubyracer', :platforms => :ruby, :group=>:assets #Rails need

gem 'inherited_resources'
gem 'has_scope'

append_file 'Gemfile' do
  <<-EOS

git 'git://github.com/tablatom/hobo.git' do
  gem 'hobo_fields'
  #gem 'dryml'
  gem 'hobo_support'
  #gem 'hobo'
end
  EOS
end

# Custom generators for DRY code
append_file 'config/application.rb' do
  <<-EOS
#{@app_name.camelize}::Application.configure do  
  config.generators do |g|
    g.test_framework :shoulda
    g.fallbacks[:shoulda] = :test_unit
    g.fixture_replacement :factory_girl
    g.scaffold_controller :inherited_resources_controller
    g.orm 'hobo'.to_sym
    #TODO: Introduce steak/capybara for integration test
  end
end
  EOS
