Hi, I just went through the Wiki20 Tutorial for Turbogears 2.0
I grabbed the latest version of TG (2.2.0) and I'm running on Python
2.6. I encountered a few errors and one or two minor "huh?!?"
situations. I created a patch for the Wiki20 tutorial text containing
fixes for the errors and two notes for the other issues. I hope it's
all good :)
I couldn't find the files for the source-code excerpts though, so I'll
give you these fixes "manually":
File: wiki_root/snapshots/7/wiki20/controllers/root.py
Line 23 and 25
Error: Uses "tg.url" and "tg.redirect" instead of "url" and
"redirect"!
File: wiki_root/snapshots/8/wiki20/controllers/root.py
Line: 46
Error: The parameter given to the "order_by" call is wrong. It should
be "pagename", with quotes!
And here's the patch for the rest....
