Rake routes & console showing one thing, app doing another

OK, I have a routing problem, that seems to be working in the console,
and with rake routes but not in the app.

I have people that have nested tasks, like so:

The solution was simple, button_to doesn't take :url => url, it just
takes the "complete_person_task_path(task) as the item.

so the button_to line becomes.

<%= button_to "Done", complete_person_task_path(task), :method => :put %>

Thanks to someone on IRC for finding this one.
