Ruby on Rails-存储当前网址以在销毁后重定向

您可以在ApplicationController中存储多个redirect_to路径...最好使用单独的before_action来执行此操作

before_action :store_back_paths

def store_back_paths

  # if session[:back_path] doesn't exist, create it as an empty array

  session[:back_path] ||= []

  # add the current path as a new entry in the array

  session[:back_path] << request.referer

  # while there are more than five entries, drop the oldest entries 
  # this is to ensure we're not storing too many entries

  session[:back_path].shift while session[:back_path].count > 5
end

进行普通重定向时，请使用pop删除数组中的最后一个元素并返回删除的值。

redirect_to session[:back_path].pop

在销毁后进行重定向时，请删除最后一个条目（指向销毁项目的显示页面），然后重定向到该条目之前的路径。

session[:back_path].pop # drops the last entry   
redirect_to session[:back_path].pop
