Question

I have a link_to code

<%= link_to "#{(pages_counter/2) + 1}", { controller: "videos", action: 'videos_navigate', offset: pages_counter }, remote: true %>

When clicking on the link it’s passing the id of the video automatically meaning I didn’t explicitly pass a video object or an id via the link_to code. Is this happening because I directly identified the controller and the action as seen in the code above? Thanks in advance

sample URL generated: /videos/videos_navigate/1?offset=2

Answer 1

If you are on a show page, where the ID is in the URL already, and your link_to doesn’t specify an ID, it will pick up the ID from the URL . The same thing would happen if you did not specify the controller, it would instead grab the current controller you are in.

So if you went to record 2 and click the same link, your URL will be /videos/videos_navigate/2?offset=2
