Rails 检测用户是否第一次访问 [英] Rails Detect If User's Very First Visit

问题描述

如果用户是第一次访问该网站，我会尝试让他们填写一份调查问卷.

I'm trying to make the user fill out a questionnaire if it is their first time visiting the site.

我的控制器设置如下:

class MainController < BaseController
end

class BaseController < ApplicationController
  before_filter :first_time_visiting?
end

class ApplicationController < ActionController::Base
  def first_time_visiting?
    if session[:first_time].nil?
      session[:first_time] = 1
      redirect_to questionnaire_path unless current_user
    end
  end
end

当我关闭浏览器并重新打开它时，我总是被重定向到调查问卷.

When I close the browser and re-open it though, I always get redirected to the questionnaire.

推荐答案

您必须在浏览器中为该用户设置 cookie，以便稍后(即在用户关闭浏览器后)进行检测.在 Rails 中设置和读取 cookie 很容易.查看文档以了解一些示例用法.http://api.rubyonrails.org/classes/ActionDispatch/Cookies.html

You have to set a cookie in the browser for that user in order to allow detection at a later time, i.e. after the user closes the browser. Setting and reading cookies in rails is easy. Checkout the documentation for some example usage. http://api.rubyonrails.org/classes/ActionDispatch/Cookies.html
