cargo_wiki allows you to install a wiki in a Rails 3 application.
Add cargo_wiki to your Gemfile:
gem 'cargo_wiki'
cargo_wiki uses compass, and you must add compass support in the assets group of your Gemfile:
group :assets do
gem 'compass-rails'
end
Then run:
bundle install
You also need to update your database:
rails generate cargo_wiki:install
rake db:migrate
Finally mount the engine in routes.rb:
mount CargoWiki::Engine => "/wiki"
You are free to mount the wiki to whatever url you want.
