wow Paul, that's just what I was looking for. The **syntax is not bound to 'args', it could be also **myargsname I guess, isn't it? Thank's a lot for your very detailed explanation. I'll use it often :) -- Elena

Zope 2.6.1 beta1 no tracebacks
by PAB Bengtsson 16 Dec '02

16 Dec '02

Installed Zope 2.6.1beta1 today and on a particular webpage I have created I get an error (no big deal) Error Type: RuntimeError Error Value: external method could not be called because it is None Fair enough, but where's the traceback? I run it with -D and there's nothing in the HTML. I have never seen a Zope error before without a traceback. Is there a reason? Is it a bug? Peter

MSWordDocument
by Jose Angelo P. Abarentos 16 Dec '02

16 Dec '02

Hello Zopistas, I've been wrestling with Eric Barroca's MSWordDocument product for days now, trying to get the HTML version of a Word file to output on my DTML document. I've tried: <dtml-var name="MyWordDoc"> but it seem to only print "MSWordDocument instance at... ". I also went to the product's source and saw a method that looks like what I needed, getDocHTML. So I tried: <dtml-var expr="MyWordDoc.getDocHTML()"> but now it's giving me an "AttributeError". I'm relatively new to Zope and Python so I would really appreciate it if any of you more experienced Zope people could care to help. -- Angelo Abarentos, a Zope newbie

Am I doing right?
by catonano 15 Dec '02

15 Dec '02

Hello all, I'd love you to give me your opinion and some help about what follows. I just downloaded Zope to my machine (MacOs X!!) and I'm an old style mac user. Now, I promised I'd have tried to realize a small solution for monday morning. I want a Zcatalogue to index some objects on the base of a property. This property is the name of the file BUT the extension, for example: code2.html property: code2 code88.html property: code88 and so on. That's because I want Zope to search for files whose code CONTAINS a given string. As far as I can tell, the standard machinery that comes with Zcatalogue searches on the files names ONLY with exact corrispondence, since the type of the file name property is ... well I don't remember. The point is I thought to give each file with a property of the right type so Zope could search adhering to my wishes. Am I right? Now these files are really a lot. Some users upload them to an ftp folder and I should have a script that adds the property to each file when it lands in my folder (AND fill it properly). How do I do this? I looked at the Folder API but I didn't find a way to detect a file arrival. Should I use a Zclass instead? And how? In the meantime I keep editing those files manually but I admit this makes me feel quite dummy. thanks so much for ANY hint Bye Catonano

Accessing manager screen
by ken 15 Dec '02

15 Dec '02

Several times now I've tried to get into the manager screen from the zopy home page (approx. http://localhost.localdomain) without any luck. I tried the user & passwd given after the install and that didn't work. So I "cd /usr/share/zope" and "python2.1 zpasswd.py access", go through the prompts. Here's the access file: admin:password That's it. There's not even a CR at the end of the one line. Because I chose "cleartext" for encoding, you can see the user is "admin" and the password is "password". At the prompt for "Domain restrictions:" I just hit "Enter" (though I tried other things... don't really know what this prompt is asking for anyway). Nothing has worked. I even restarted zope a few times in between some of these attempts. So what do I have to drink to log into the manager screen. tia, ken

TALES and Acquisition
by Dan Fairs 15 Dec '02

15 Dec '02

Hi, I've just had a quick flick through the archives but can't find the answer to my question. I'm a newbie to TAL and TALES, though I've dabbled in Zope before. Now I'm starting to play with page templates, as they seem more elegant than DTML. However, I have one question. Is it possible for TALES expressions to make use of acquisition? As a trivial example, say I have a script called getRoot in the root folder that returns the URL of where that script lives. Say also I have a folder off the root called MyFolder, which contains the following link: <a href="Link" tal:attributes="href container/getRoot">My Link Somewhere</a> Now, I would intuitively have expected Zope to look in the container for getRoot (ie. MyFolder), fail to find it, and look in the parent folder, then execute it there. However - this doesn't happen. And I can't find any mention of acquisition in the TAL docs. How do the two interoperate? Pointers to relevant comments/docs are appreciated? Many thanks, Dan

Date calculations in Zope
by Greg McCall 15 Dec '02

15 Dec '02

Hi I am having trouble performing date calculations in Zope. I have a variable called dob which returns a date of birth from MySQL Ie. Date of Birth=<dtml-var dob> works fine I would like to be able to list the current age in years and months I can get a years calculation with the following line Age in years = <dtml-var expr="ZopeTime().year()-dob.year()"> A similar line works using months Months = <dtml-var expr="ZopeTime().month()-dob.month()"> I don't know how to do the month above when say you are in month 1 and you subtract month 12 Also, how can the results be placed in a form. Eg <INPUT TYPE="TEXT" NAME="AgeYears" value="0"> <INPUT TYPE="TEXT" NAME="AgeMonths" value="0"> I tried putting the above dtml-var code in the value attributes without success. Thanks Greg
