问题描述

在我的Rails应用程序中,为了在用户注册时将用户国家(使用Geocoder gem)保存到用户表中,并使用另一个

In my Rails app, in order to save user country (using Geocoder gem) into the User table when the user signs up, and using another SO question, I have changed something in my controllers/confirmations_controller.rb but am getting a serious error I don't understand nor manage to solve:

def after_sign_up_path_for(resource)
    if Devise.allow_insecure_sign_in_after_confirmation
      resource.update(user_country: request.location.country)
      after_sign_in_path_for(resource)
    else
       resource.update(user_country: request.location.country)
       root_path
    end
  end

有什么奇怪的是用户被保存在我的本地数据库上的一切都很好(包括我想要的用户countryas)。但是,随着我收到一个错误页面,并出现以下错误信息,但是有一些事情必须发生:

What's weird is that the user is saved with everything fine (including user countryas I wanted to have) on my local database. But then something must happen as I get an error page with the following error message:

undefined method `model_name' for TrueClass:Class

推荐答案

尝试这样做

def after_sign_up_path_for(resource)
    if Devise.allow_insecure_sign_in_after_confirmation
      resource.update(user_country: request.location.country)
      super(resource)
    else
       resource.update(user_country: request.location.country)
       root_path
    end
  end
