Question

如何將簡單驗證碼2與設計集成？我瀏覽過其他問題，但不滿意。

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 

它擔當我的目的..
