dtml-if Newbie Question
by Alfredo P. Ricafort 05 Nov '02

05 Nov '02

Hi, >From the 'Zope Book' the statement <dtml-if variable> means that 'if the..variable does not exist, then this condition is false'. I found that this is not true. When I tried using dtml-if to a non-existent variable, I got a 'key error'. So how do I check if the variable does not exist ? Tks. AL

Uses of METAL?
by Alec Munro 05 Nov '02

05 Nov '02

Hi all, I've a few things with Zope so far, mostly using ZPT and python scripts, and I haven't found any serious uses for METAL. In almost every case that I've been tempted to implement METAL, I've found I could accomplish the same thing with ZPT and/or python scripts. My question is: How are other people using METAL in serious applications? I would love to hear how it is being used by those more familiar with Zope than myself. Thanks very much, Alec Munro

LoginManager and page templates
by Hedley Roos 05 Nov '02

05 Nov '02

Hi I am trying to use page templates as forms for LoginManager, but I can't get it to work. >From LoginManager.py (snippet below) I have traced the problem to line (A) if hasattr(self,'forbiddenPage'): if response.unauthorized.__name__=='unauthorized': def lm_unauth(lm=self,request=request,user=user,roles=roles,old=response.unautho rized): request['AUTHENTICATED_USER'] = user lm.forbiddenPage(lm, request, needroles=roles) if hasattr(lm,'loginForm'): lm.loginForm(lm, request, needroles=roles) (A) old() response.unauthorized = lm_unauth *Nothing* happens at that line when loginForm is a page template. Any ideas? I have tried a workaround using the normal DTML to call a macro and fill a slot (I really do need the macro for my login form), and the call macro part works decently, but not the fill slot part. I'd rather have page templates all round.

Oh - yes of course i do!! -- You save so much time with your really short answers so you can spend it now!! ;-) -------------- No - Seriously: I respect your excellent zope knowhow, Dieter. - So big is my wish you would respect me and believe that i have searched zope.org and the net for min.ten minutes before posting. So please consider just not answering on a/my question instead of posting only 'howto on zope.org', this really offends me.

download problems
by Peter Hiltner 05 Nov '02

05 Nov '02

Dear collegues, as an ADASS XII-participant I just tried twice to download Zope-2.6.0-linux2-x86.tgz for use on -evidently- a Linux PC. Download (from Netscape-Communicator 4.76) seemed to work fine until the end, but then a Netscape message with the name of the downloaded file appeared, where I only could click "OK", and when doing so all disappeared and no Zope...tgz-file was there. What's the problem? With kind regards Peter Hiltner

Zope intranets: hardware requirements
by Nicolas Romero 05 Nov '02

05 Nov '02

Hi all, In order to participate in Zope proliferation, I am looking for facts and numbers about the hardware requirements of a Zope/CMF(/Postgres) platform (because this is the first question after you've managed to convince the client of how Zope is great). So, experienced zopers, which hardware do you use or recommend to your clients to host intranet/extranet sites in a decent way ? I am particularly interested in sites hosting few users (<200) and many docs... Btw, where is the Hardware page on www.zope.org ? I remember of it, but can't find it nowhere today. Best regards, -- Nicolas Romero, ADP3i <http://www.adp3i.fr>

Re: [Zope] Data.fs grows rapidly in size and crashes Zope (solved)
by hpinson＠indepthl.com 05 Nov '02

05 Nov '02

The things I get myself into. I hope this solution will be of help to others. Let me first describe the problem. My Zope data.fs was growing at a alarming rate. Friday night, the 2GB file size was exceeded (the 2.5.1 server hosts a popular political site, and has been up non-stop for about a month). The z2.log and STUPID_LOG_FILE revealed nothing odd. A tranalyzer run also showed zope behaving apparently normally. What else could it be? Some malicious anonymous user triggering an insecure process? That should show up in the logs. More likely, it would be a programatic change that I had made myself, causing a runaway write process. But I had not made any changes in over two weeks. Turns out that I had created a HostTracker counter object at about that time: http://www.zope.org/Members/Ioan/HostTracker ...which was merrily populating a table with the statistics of a busy site. Kaboom! I had forgotten to remove this, since getting AWStats to parse the Z2.log for multiple stand-alone Zope virtual hosted sites. So be careful with a HostTracker counter, especially if your site is busy. Don't forget to purge it regularly. Thanks to everyone who helped solve this!

Anyway, I was looking for how to do something similar to this. In DTML, after making a round-trip to Formulator, one can call variables thus: <dtml-var my_var_from_the_form_that_user_filled_out> I've tried to research how to do this one myself before asking, but how do I do this?
