Similar functionallity added to Padrino. This gem will no longer be maintained.

Padrino CSRF is a plugin for the Padrino web framework which adds cross-site request forgery protection.

Include it in your project's Gemfile with Bundler:

gem 'padrino-csrf'

Modify your app/app.rb file to register the plugin:

class ExampleApplication < Padrino::Application
  register Padrino::CSRF
end

prevent_request_forgery
When enabled, will automatically verify the CSRF authentication token on all post, put, and delete requests.

You can of course disable this on a request by request basis:

enable :prevent_request_forgery

post :register do
  # request is checked
end

post :register, protect: false do
  # request isn't checked
end

Or if you prefer, you can disable it by default, and enable it on a request by request basis:

disable :prevent_request_forgery

post :register do
  # request isn't checked
end

post :register, protect: true do
  # request is checked
end
