ruby-on-rails - 在没有身份验证的情况下将我的网站限制为每位用户一个 - 比较数组中的日期

Question

如何在没有身份验证的情况下仅由一个用户限制页面，并且在第一个用户和第二个用户之间延迟 3 分钟。如果有人有线索或解决方案？

这是我尝试做的事情：一个独特的用户登陆我的页面并填写表格，因为我想通过创建一个 User.last 来选择他，我需要他在我的页面上是唯一的（不打扰注册并成为确保我使用 User.last 选择了正确的用户）并等待 3 分钟让第二个用户访问此页面。就像我有 10 个人试图访问我的网站，其中 1 个人在填写表格，其他 9 个人正在排队等待访问我的页面。Actualluy 尝试在 Ruby on Rails 中执行此操作。

我对该字段的视图如下所示（需要在此页面上只允许一个用户）：

<div class="container">
<center><h1>New Connection </h1></center>
    <%= form_with model: @email, local: true do |form|%>
        <% if @email.errors.any? %>
        <div id="error explanation" class="alert alert-danger">
            <p>Erreur(s) : </p>
                <ul>
                    <% @email.errors.full_messages.each do |message|%>
                        <li><%=message%></li>
                    <% end %>
                </ul>
        </div>
        <% end %>
        <div class="form-group">
            <%= label_tag :email %> :
            <%= form.email_field :email, placeholder: "Email", class: "form-control" %>
        </div>
        <div class="form-group">
        <%= form.submit class: "btn btn-primary btn-lg btn-block", value: "Se connecter" %>
        </div>
    <%end%>
</div>

我的电子邮件控制器：

class EmailsController < ApplicationController

  def index
    redirect_to root_path
  end

  def new
    @email = Email.new
    sessions = ActiveRecord::SessionStore::Session.pluck(:updated_at)
#return an array like this :

正如评论部分所建议的，我尝试使用会话，我可以访问由 rails 进行的会话，request.session_options[:id]但我如何计算它们？

编辑 2：

正如 ARK 在评论部分所建议的，我尝试使用 Rails 创建的 Session，我编辑了我的控制器部分。我怎么能说如果一个会话与前一个会话在同一分钟内，将最后一个重定向到另一个 url ？
