Using Rails 3 gem Manifesto

I am trying to use the HTML5 manifest function using a gem called Manifesto. I am stuck on the instructions for usage. I cannot figure out where those settings are supposed to go.

Any ideas? Perhaps a better gem?

Thankful for all help!

You can put you settings in a file under config/initializers/. Use an informational name (like manifesto.rb). However you don't need a config with the basic usage.

In your Gemfile file, add:

gem 'manifesto'

then install via bundle:

bundle install

create the file app/controllers/manifest_controller.rb

class ManifestController < ApplicationController
  def show
    headers['Content-Type'] = 'text/cache-manifest'
    render :text => Manifesto.cache, :layout => false
  end
end

in config/routes.rb add:

match '/manifest' => 'manifest#show'

Restart your app and view the result at http://localhost:3000/manifest

You can pass the option directly to Manifesto.cache like:

# change
render :text => Manifesto.cache, :layout => false
# to
render :text => Manifesto.cache(:directory => './mobile', :compute_hash => false), :layout => false

Or use a YAML file and an initializer.

The config/manifesto.yaml file:

# directory is relative to Rails root
directory: './mobile'
compute_hash: false

The config/initializers/manifesto.rb file:

# Load the config file and convert keys from strings in symbols (the manifesto gem need symbolized options).
MANIFESTO_CONFIG = YAML.load_file(Rails.root.join('config', 'manifesto.yml').to_s).inject({}){|config,(k,v)| config[k.to_sym] = v; config}

And pass the loaded config to Manifesto.cache like:

# change
render :text => Manifesto.cache, :layout => false
# to
render :text => Manifesto.cache(MANIFESTO_CONFIG), :layout => false
