Blog ยป Template for DRYer rails demo blog

Posted on 17 Aug 2012 14:15

In Getting Started with DRYer Rails 3.2, I showed how small code you need to create a blog or any other application. But where is the code to try? Here is the rails template to create a DRY demo blog for you. Simply do

rails new demo_blog -m https://raw.github.com/gist/3378950/699589853464e4654ae7e5d183de126b11f4720f/template_umur_demo_blog.rb
#Note that you need bundler and rails gems in your system or current rvm environment.
#Usage example: rails new demo_blog -m demo_blog_recipe.rb
# Required gems
gem 'therubyracer', :platforms => :ruby, :group=>:assets #Rails need
gem 'inherited_resources'
gem 'has_scope'
append_file 'Gemfile' do
git 'git://github.com/tablatom/hobo.git' do
  gem 'hobo_fields'
  #gem 'dryml'
  gem 'hobo_support'
  #gem 'hobo'
# Custom generators for DRY code
append_file 'config/application.rb' do
#{@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
git :init
git :add => "."
git :commit => "-a -m 'Initial commit'"
# Let's make a demo blog now
say ("Installing gems so that we can scaffold...")
run 'bundle install'
generate :scaffold,  'Post title:string text:text'
route "root :to => 'posts#index'"
inject_into_class 'app/models/post.rb', 'Post' do
  attr_accessible :title, :text
  default_scope :order => 'created_at DESC'
  validates :title, :presence => true,
                    :length => { :minimum => 5 }
inject_into_class 'app/controllers/posts_controller.rb', 'PostsController' do
  respond_to :html, :json

Note that you need bundler and rails gems in your system or current rvm environment.
Andrea Singh describes a cool way to create a new rvm gemset for your new project down in section "Using RVM". I advice you to use her bootstrap.rb. I am thinking about making it a global Thor script.
