通过Nokogiri显示数据的正确方法是什么？

In my application I have a field where users can enter a URL and then products will be scraped from that URL. I watched "Screen Scraping with Nokogiri", and I created the result I wanted; I put in a URL and the data gets mined.

在我的应用程序中,我有一个字段,用户可以在其中输入URL,然后从该URL中删除产品。我看了“用Nokogiri进行屏幕刮擦”,我创造了我想要的结果;我输入了一个URL,数据被挖掘出来。

Do I use a Rake task?

我是否使用Rake任务?

If I do use a Rake task, how do I put the user-submitted URL in that Rake task? I read on a previous SO post (not sure where) that executing Rake tasks from the controller is a big security no-no.

如果我使用Rake任务,如何将用户提交的URL放在Rake任务中?我读过以前的SO帖子(不知道在哪里)从控制器执行Rake任务是一个很大的安全禁忌。
