Return the board to the rails and store it

I know that it could sound an “easy-question” but I am new in rails and I don’t know if I am structuring correctly my app.

My app is “easy” it has to connect a webpage and collect all JPG links and store the links in a database.

In my “model folder” I have defined my functions:

class JPG div", :items  => Scraper.define {
          process "div.thumb>a", :link => "@href"

        result :items

      uri = URI.parse(URI.encode(web))
      return scraper.scrape(uri)

As you can see the function main_web
returns an array.

Well my question is “easy”. If I want to call the function and to storage the information in the database, how do I have to do it?

I don’t want to show the information in the screen I only want to storage the data in the database but from where do I have to do the call? view? or controller?
