Using Mustache in Rails 3

Mustache is …

So, for binding mustache in your Rails3 project, add the following gems to you Gemfile

gem 'mustache'
gem 'mustache_rails3'

You can enable the mustache template handler by running

rails g mustache:install

Then in RAILS_ROOT/config/initializers/mustache.rb

rails g mustache:install
# Be sure to install mustache gem and include mustache gem in project Gemfile.
# Template Handler
require 'mustache_rails'
# Generator
Rails.application.config.generators.template_engine :mustache
# Need to change dynamically when the theme changed
Mustache::Rails::Config.template_base_path = Rails.root.join('themes', 'n5ken', 'templates')
Mustache::Rails::Config.shared_path        = Rails.root.join('themes', 'n5ken', 'templates', 'shared')

# You can change these defaults in, say, a Rails initializer or
# environment.rb, e.g.:
#
# Mustache::Rails::Config.template_base_path = Rails.root.join('app', 'templates')
module Config
  def self.template_base_path
    @template_base_path ||= ::Rails.root.join('app', 'templates')
  end
  def self.template_base_path=(value)
    @template_base_path = value
  end
  def self.template_extension
    @template_extension ||= 'html.mustache'
  end
  def self.template_extension=(value)
    @template_extension = value
  end
  def self.shared_path
    @shared_path ||= ::Rails.root.join('app', 'templates', 'shared')
  end
  def self.shared_path=(value)
    @shared_path = value
  end
end

If we run scaffold to create a product model, we will get the response messages as follow:

$:/var/projects/template# rails g scaffold Product title:string description:text
      invoke  active_record
      create    db/migrate/20110703090715_create_products.rb
      create    app/models/product.rb
      invoke    test_unit
      create      test/unit/product_test.rb
      create      test/fixtures/products.yml
       route  resources :products
      invoke  scaffold_controller
      create    app/controllers/products_controller.rb
      invoke    mustache
      create      app/views/products
      create      app/views/products/index.rb
      create      app/templates/products/index.html.mustache
      create      app/views/products/edit.rb
      create      app/templates/products/edit.html.mustache
      create      app/views/products/show.rb
      create      app/templates/products/show.html.mustache
      create      app/views/products/new.rb
      create      app/templates/products/new.html.mustache
      create      app/templates/products/_form.html.mustache
      invoke    test_unit
      create      test/functional/products_controller_test.rb
      invoke    helper
      create      app/helpers/products_helper.rb
      invoke      test_unit
      create        test/unit/helpers/products_helper_test.rb
      invoke  stylesheets
      create    public/stylesheets/scaffold.css

From the message, it will generate mainly three folders: controller, view, templates.
