RailsCloudflareTurnstile

This is a Rails plugin adding support for Cloudflare Turnstile

Usage

How to use my plugin.

Installation

Add this line to your application's Gemfile:

gem 'rails_cloudflare_turnstile'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_cloudflare_turnstile

Next, configure it by creating a config/initializers/cloudflare_turnstile.rb with contents like the following:

RailsCloudflareTurnstile.configure do |c|
  c.site_key = "XXXXXX"
  c.secret_key = "XXXXXXXX"
  c.fail_open = true
end

To totally disable Turnstile, you can set c.enabled = false and all other config values are ignored.

To use Turnstile for a view:

1. Call cloudflare_turnstile_script_tag in your layout
2. Call cloudflare_turnstile in your form View
3. Call validate_cloudflare_turnstile as a before_action in your controller.

If the challenge fails, the exception RailsCloudflareTurnstile::Forbidden will be raised; you should handle this with a rescue_from block.

By default, in development and test mode, a special mock view will be inserted if real credentials are not present. To disable this, set the mock_enable property of the configuration to false.
