The problem is that when you don't specify an extension in the URL()
function, it automatically defaults to the extension of the current request.
So, when you go to /mywiki/default/news.rss, that sets the extension of the
current request to 'rss'. So, when the news() function creates the URLs
using the URL() function, it automatically adds .rss extensions to the URLs.
The way to avoid that is to explicitly set the extension to 'html':
link = URL('show', extension='html', args=row.id)
Of course, the problem with that is the URLs in the RSS feed will now look
like /mywiki/default/show.html/1, which will work but is ugly.
There's a trick, though -- instead, set extension to False:
link = URL('show', extension=False, args=row.id)
In that case, the URL() function will not use request.extension (it only
does that if extension=None), nor will it try to add an extension to the
function name. I think this change will work with the upcoming release as
well (which includes a new version of the URL() function).
Note, I went ahead and made the above correction in the book.
