ruby-on-rails-4 - 如何在 rails 4 中使用 simple-captcha 和 devise

Question

如何将 simple-captcha2 与设计集成？我浏览了其他问题，但不满意。

Answer 1

我只是添加registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController

  # POST /resource
  def create
    if simple_captcha_valid?
        super
    else
        build_resource(sign_up_params)
        clean_up_passwords(resource)
        flash.now[:alert] = "There was an error with the Captcha code below. Please re-enter the code."
        render :new
    end
  end

end

它达到了我的目的..
