nesta-rails is a Rails plugin that seamlessly integrates Nesta CMS into your Rails application. Rather than mounting Nesta as a Rack application alongside your Rails application, it replaces Nesta's Sinatra actions with a Rails controller that uses Nesta's library code to render the files in your content/pages directory.
A couple of Nesta's view helper methods have been renamed to avoid conflicts with Rails's own, so until Nesta 0.10.0 is released you'll need to use the development version of Nesta from GitHub. Update your Gemfile like this:
gem "nesta", :git => "https://github.com/gma/nesta.git"
Then add nesta-rails to your Rails app's Gemfile and re-bundle your app:
$ echo 'gem "nesta-rails"' >> Gemfile
$ bundle
Now you can generate a controller, a helper, and a default template for
rendering your pages. The generator will also add some routes to
config/routes.rb for you.
$ rails generate nesta
create config/initializers/nesta.rb
create app/controllers/nesta_controller.rb
create app/helpers/nesta_helper.rb
create app/views/nesta/page.html.haml
create app/views/nesta/atom.haml
create app/views/nesta/sitemap.haml
route mount NestaController.action(:show), :at => '/'
route match 'sitemap.xml' => 'nesta#sitemap'
route match 'articles.xml' => 'nesta#feed'
You'll want to move the routes to the bottom of the file if you've got existing routes.
That's it!
It's now up to you to update your templates/CSS accordingly, but Nesta's content should be rendered within your Rails app's application layout...
If you want to make changes to the generated controllers and helpers, go ahead. That's why they're generated; you'll probably want to hack on them at some point.
