throwing exceptions when <img src=...> does not exist
by Lee 20 Feb '01

20 Feb '01

hi, i have a little problem re: img and dtml-try tags: there are images stored on an external server - these are named after student's universtity usernames e.g. lreilly.gif. represents moi, lee reilly. the problem is that it is not guaranteed that such an image is stored for *every* student so i want to do something like... <dtml-try> <img src="d:\<dtml-var uname>.gif" width="240" height="180"> <dtml-except> <img src="d:\dilbert.gif" width="240" height="180"> </dtml-try> i.e. if the student gif exists display it otherwise display the file dilbert.gif. if the files were stored on zope then modifying the <img> tags to plain <dtml-var uname> would work fine except that (i) they're not stored on my server (ii) <dtml-var uname> would display the username and not the image (id=username) - i think this can be overcome though. is there anyway to adapt the above code to actually *throw* an exception when the image is not located. the results of the above code are as follows: if the files exist => it is displayed if the file doesn't exist => nothing is displayed anybody have any thoughts / advice? cheers, lee -- Lee Reilly mailto:lee.reilly@ntlworld.com http://www.footkick.co.uk

Two of my most beloved and heavily used books are from New Riders, Paul DuBois' "MySQL" and Dave Beazley's "Python Essential Reference".

I'm normally a Gnome sort of person, so I haven't touched Konq for a LONG time. Last I played with it, it felt pretty raw, but I've heard all sorts of nice things about it lately. Mozilla is also (finally) starting to shape up. I've have really good luck with the 0.7 release. One it's up, it renders nicely and seems to interact with Zope well. It is a pig, though. I have LinuxPPC running on a G4 450, and it does really well there. But my primary development box at work is a PII 350, and Mozilla on that box is frustratingly slow to start. Galeon (http://galeon.sourceforge.net) is nice, and zipper than Mozilla. But it has some occasional strange issues with the Zope management interface. I was using it as my regular browser, but (happily) I've been doing so much Zope development recently that I've switched back to strait mozilla. I do like Mozilla a lot better than NS for Zope development, if only for the fact that it gives me a much better idea of how things are going to render on IE than NS4.5.x does... > Saying that, I have not tried Opera in some time... perhaps they've > addresses some of THEIR issuse... it could be worth a > try...http://www.opera.com Would be interested to hear how well it interacts w/Zope... > Have a better one, > Curtis Maloney. //glw

SV: [Zope] Matching a date that's in a Zcatalog field index
by Geir Bækholt 19 Feb '01

you could always try something like <untested> <dtml-in "NewsCatalog(_.DateTime.isCurrentDay(CreateDate))"> </untested> hope it works.. :-) Geir Bækholt geirh(a)funcom.com >I've set a CreateDate property on a bunch of files--basically, i grab the >ZopeTime at the time of the DTML Document's creation and write it to a >CreateDate property of type date. Now I'm trying to pull individual dates >out of the Catalog--for instance, to show all of the stories written today. >What's the proper syntax for matching this stuff? This doesn't work: > ><dtml-in "NewsCatalog(CreateDate.Date()=_.ZopeTime().Date())"> > ></dtml-in>

Making backups
by Spinwing 19 Feb '01

19 Feb '01

Hello maybe mine is a stupid question, but I haven't figure out how to do it properly. Say I have some folders I want to backup automatically. Normally I would export them and then make a bacup of the export directory, but how can I do it in a way that at a specific time cron will export them ? Thanks for the answer Stefano

Zope products install issue
by Andrei Cenja 19 Feb '01

19 Feb '01

Hello ! I've successfully installed Zope 2.3.0 on an Intel machine running RHL 7.0. But when I try to install additional modules for Python (mysqlmodule, for instance), they "discover" the RH Python and happily install themselves into /usr/lib/python/site-packages. So when I install the MySQL DA in the Zope Products directory, it reports that Python can't find the mysqlmodule, which is no surprise as Zope comes with and runs on its own Python. So I have to copy the site-packages directory from the RH 7 Python to the Zope Python, and then everything works out fine. But this isn't an elegant way at all. Could someone give me a hint to solve this some other way ? Or tell me what I am doing wrong ? Thank you. Andrei Cenja, Bucharest, Romania.

Your Web server has closed the communication channel to Zope, maybe due to a timeout (Zope may have been too slow to answer). It should not be a problem, though. Dieter

RE: [Zope] Upgrading to 2.3.0 from 2.2.0

I would say go for it -- Zope 2.3.0 is real nice -- but first test it to make sure the new version is compatible with all of your Products. I haven't been able to upgrade my largest Zope site because 2.3.0 has problems w/ the EventFolder product. -- Kit O'Connell Zope Administrator kito(a)clearcommerce.com 'yes is a world & in this world of yes live (skilfully curled) all worlds' - e.e. cummings -----Original Message----- From: Christian Adams [mailto:christian.adams@RevolutionLtd.com] Sent: Monday, February 19, 2001 9:09 AM To: 'zope(a)zope.org' Subject: [Zope] Upgrading to 2.3.0 from 2.2.0 Anyone had any bad experiences with this?
