Question

What is the best way to add a check for accepting terms of use in a rails app?

I can\'t seem to get validates_acceptance_of working quite right. I added a b

This is a working Rails 4 solution:

Terms of service doesn't need to be a column in the database

Form

= f.check_box :terms_of_service

models/user.rb

validates :terms_of_service, acceptance: true

And most important, devise will sanitize your parameters and terms of service will be removed from the submitted params. So:

registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController
  before_filter :configure_permitted_parameters

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) do |u|
      u.permit(:full_name,
        :email, :password, :password_confirmation, :terms_of_service)
    end 
  end
end
