ImportError: No module named template

Hi,

being a "Kid" and TurboGears newbie (with quite some experience in
Python and TAL), I tried a quite simple template:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://
www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:py="http://purl.org/
kid/ns#"
py:extends="'master.kid'">
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type"
py:replace="''"/>
<title>Welcome to TurboGears</title>
</head>
<body>
<div class="main_content">
<pre py:content="template">item</pre>
<div py:if="template == 'item'">
single entry
</div>
<div py:if="template == 'list'">
list of entries
</div>
</div>
</body>
</html>


I have a controller method which should point to the proper URL;
however, all I get is the ImportError mentioned above, which is of no
use to me. Of course, I'm totally unaware of a module named
template_util I'd be responsible of; I found one in the kid-0.9.6-
py2.5.egg\kid directory, but this doesn't seem to be found, does it? I
tried to add a kid.pth file, but this didn't help (or I didn't do it
right...).

Is there anything in the standard master.kid (from tg-admin ) I must
match? How can I make my template work? Any hint welcome!

(Python 2.5.1, WinXP, TurboGears 1.0.4.4; Kid 0.9.6)

Btw, I read something about Genshi giving more informative error
messages; thus, it might be better to use Genshi (or, if this is easy
to accomplish, TAL/METAL). Any pointers regarding this?

Thanks a lot,

Tobias

template_util is an internal module of Kid that normally you needn't
care about. The template looks ok. You probably need to show us the
controller and the full stack trace. Do you have the latest TurboKid
(1.0.4) installed?

Recent Kid versions give much better error messages. The main advantage
of Genshi is better performance. I'm not aware of anybody using TAL with
TurboGears, probably because Kid/Genshi are very similar and in my
opinion easier to use and more straightforward than TAL/METAL.

If you're using TG 1.0, I recommend sticking with Kid and switching to
Genshi when updating to TG 1.1 or 2.0.

Hi, Chris,

thanks for answering.

Yep: TurboKid-1.0.4-py2.5.egg

Well, here it is:

Well, that's a matter of taste; knowing Zope and Roundup, I like the
prototype-data-included philosophy, and there are quite useful error
messages...

Ah, ok. Once it works, I'll consider that ;-)

This looks suspicious. Do you have a template named "kid" (as basename,
not as extension!). I can imagine that can cause some problems.

Yes, I had -- and yes, it did... I had a test template for the built-
in variables and just couldn't think of a better name. After cleaning
this up and restarting the server, it works now.

Ok, so it bit me that templates are compiled to modules -- and are
apparently put in sys.path before the "real" modules.

Thanks a lot,
