#mobile? ⇒ Boolean

Here’s the concept behind this “mobile content negotiation” hack: In addition to the main, AJAXy Web UI, Tracks has a lightweight low-feature ‘mobile’ version designed to be suitable for use from a phone or PDA. It makes some sense that the pages of that mobile version are simply alternate representations of the same Todo resources. The implementation goal was to treat mobile as another format and be able to use respond_to to render both versions. Unfortunately, I ran into a lot of trouble simply registering a new mime type ‘text/html’ with format :m because :html already is linked to that mime type and the new registration was forcing all html requests to be rendered in the mobile view. The before_action and after_action hackery below accomplishs that implementation goal by using a ‘fake’ mime type during the processing and then setting it to ‘text/html’ in an ‘after_action’ -LKM 2007-04-01

Returns:

  • (Boolean)
