Summary
Update
In a recent version of this gem, the model helpers have since been deprecated and removed. Instead of calling the validator within your model, you can now call them in your controller on a per action basis.
For example, if you have a subject honeypot, you can add this to your controller if you are only wanting to capture it for the create action.
invisible_captcha only: :create, honeypot: :subject, on_spam: :spam_received private def spam_received redirect_to root_path end
# Gemfile gem 'invisible_captcha'
# _form.html.erb
<%= invisible_captcha %>
<%= f.invisible_captcha :subtitle %># Controller
invisible_captcha only: :send_contact, on_spam: :spam_detected
private
def spam_detected
redirect_to root_path, alert: 'Spam detected'
end# config/initializers/captcha.rb
InvisibleCaptcha.setup do |config|
config.sentence_for_humans = 'If you are a human, ignore this field'
config.error_message = 'You are a robot!'
config.honeypots += 'fake_resource_title'
config.visual_honeypots = false
