Mustache support for Rails 3

This generator and template handler for Mustache in Rails 3 is based on the work of Paul Barry, Louis T., and Martin Gamsjaeger. I am indebted to them for allowing me to stand on their shoulders.

This is also available as a rubygem.

I'm just getting started. This really is a low-numbered prerelease. :-) I have asked for comments on the mustache project's Rails Support issue ticket. Please leave feedback there, and thanks.

Views & Templates

For your view files, subclass Mustache::Rails as (:controller)::(:action) in app/views/:controller/:action.rb

#app/views/home/index.rb

class Home::Index < Mustache::Rails
  def world
    'New Caprica'
  end
end

Mustache::Rails registers a TemplateHandler for ".rb" files. Templates go in app/templates/:controller/:action.format.mustache

#app/templates/home/index.html.mustache

Hello {{world}}!

Layouts

Layouts work much the same way, using a similar naming convention. Subclass Mustache::Rails as Layouts::(:layout) in app/views/layouts/:layout.rb

#app/views/layouts/main.rb

class Layouts::Main < Mustache::Rails
  def default_title
    'A Cylon fleet has jumped into orbit!'
  end
end

Place the template for your layout in app/templates/layouts/:layout.format.mustache

#app/templates/layouts/main.html.mustache

<h1>{{default_title}}</h1>
{{{yield}}}

Instructions

A Rails 3 reminder: be sure to add

gem 'mustache'

to your project's Gemfile before running any generators or starting the server.

If you're using the mustache_rails3 gem, be sure to also add

gem 'mustache_rails3'

You can enable the mustache template handler by running

rails g mustache:install

in your project directory.

TODO:

• Add controller-retrofit generator to build default mustache views for existing controllers
• Generate different fields for different attribute types
• Add support for easy conversion of Rails::Mustache objects to JSON representations
• Think about allowing to overwrite layout methods in subclassing views: http://github.com/defunkt/mustache/blob/master/lib/mustache/sinatra.rb#L79-82 http://github.com/defunkt/mustache/blob/master/lib/mustache/sinatra.rb#L96-102
