Zope Static Mirror
by Lee Harr 24 May '03

24 May '03

Hi; I was looking a few weeks ago for something to help me make a static mirror of my zope site so that I could burn it on to a CD. wget was not working very well for me, and the zopemir.py script was not really finished... so, I have been working on a new script which comes much closer to getting this job done for me: http://www.zope.org/Members/leeharr/Products/zope_static_mirror/ _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963

Calling a function, which deletes an element of a list, from a hyperlink and returning a display page from that function. The URL in the browser address bar shows the the call to the function (and passed variables). How do you change the returned URL so that the display page shows the changes? We tried RESPONSE.redirect(foo) and that worked except the display page didn't show the changes that had been made. The browser didn't reload the page (perhaps assuming it was not changed and used the cached version?) John -

How to override DTMLFile?
by Peter Bengtsson 24 May '03

24 May '03

I want to override DTMLFile from Globals in my own special product. I managed to do this:: class PeterDTMLFile(DTMLFile): def foo(self): return "works" Then from somewhere else I do:: manage_edit = PeterDTMLFile('dtml/manage_edit', globals()) This works but doing <dtml-var foo> raises a KeyError. I've looked at Localizer and how they override DTMLFile's __init__ and _exec method. But if I try to do:: # pointless inheritance hack but for testing class PeterDTMLFile(DTMLFile): def __init__(self, name, _prefix=None, **kw): apply(DTMLFile.inheritedAttribute('__init__'), (self, name, _prefix), kw) Which in effect is pretty pointless, I get the following error when trying my manage_edit:: Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 62, in mapply AttributeError: 'None' object has no attribute 'co_varnames' So, can anybody tell me how to override the DTMLFile class (and possible also the PageTemplateFile) Grateful, Peter

Fwd: Re: [Zope] again Zope and RedHat 9 threading problem
by Jimi Thompson 23 May '03

23 May '03

I keep trying to unsubscribe from the list, since I am not using Zope any more. The mailman keeps telling me that I am not subscribed, but I keep getting an email here and there which DO NOT appear to be addressed to me, but the Zope list, which I am supposedly no longer a part of. It's very confusing. Can you please take a look at it? >X-Auth-No: >Subject: Re: [Zope] again Zope and RedHat 9 threading problem >Cc: zope(a)zope.org >To: Marcus Schopen <marcus.schopen(a)uni-bielefeld.de> >From: Jens Vagelpohl <jens(a)zope.com> >X-MailScanner: Found to be clean >X-Spam-Status: No, hits=-9.2 required=5.0 >tests=BODY_PYTHON_ZOPE,EMAIL_ATTRIBUTION,IN_REP_TO,QUOTED_EMAIL_TEXT,SPAM_PHRASE_00_01,SUBJ_PYTHON_ZOPE,USER_AGENT_APPLEMAIL >X-Spam-Level: >Sender: zope-admin(a)zope.org >X-BeenThere: zope(a)zope.org >X-Mailman-Version: 2.0.13 (101270) >List-Help: <mailto:zope-request@zope.org?subject=help> >List-Post: <mailto:zope@zope.org> >List-Subscribe: <http://mail.zope.org/mailman/listinfo/zope>, > <mailto:zope-request@zope.org?subject=subscribe> >List-Id: Users of the Z Object Publishing Environment <zope.zope.org> >List-Unsubscribe: <http://mail.zope.org/mailman/listinfo/zope>, > <mailto:zope-request@zope.org?subject=unsubscribe> >List-Archive: <http://mail.zope.org/pipermail/zope/> >Date: Fri, 16 May 2003 08:27:39 -0400 > >the only difference to a stock RH9 i have is the latest updates, and >i put them on not because of that perceived threading issue but >simply because i had the time and they were available... > >jens > > >On Friday, May 16, 2003, at 08:21 US/Eastern, Marcus Schopen wrote: > >>Jens Vagelpohl wrote: >>>have you run "ps -m" to force ps to show all threads (it will not >>>do that by default)? if i do that on my desktop i get the >>>expected number of threads without any trickery. >> >>Oh my good .... that's the trick!?

RE: [Zope] Problem with a python script

[Andreas Pakulat] > got a really weird problem here: > Error Type: ValueError > Error Value: unsupported format character '"' (0x22) at index 45 > > testing the following python script: > >.... > fmtstr += ' href="index_html?activetab=%d">%s</a></td>' > %(lastelem,tabs[lastelem]) > fmtstr += '<td class="headerborderwhite"><img src="%s" ' %(isrc) > fmtstr += ' width="10" height="10" > style="display:block;width:2em;height:2em"></td></tr></table></td>' > fmtstr += '<td > style="background-color:#FFFFFF;width:95%"><img src="%s"' %(spsrc) > > fmtstr += ' width="3" height="3"></td></tr>' > > return fmtstr Even though Andreas is happy to have found the error, I would like to urge that Python scripts not be used to return markup at all. Instead, return a data structure to the calling page and let the page format the data - either with dhtml or zpt, it doesn't matter in this regard. Writing markup with Python has two big problems, good though Python is - 1) It is really hard to get markup right, as Andreas's example shows. Little errors are easy to make and hard to see. 2) If you want to change the look of the page, you have to rewrite your script, which is painful and prone to the same errors all over again. Using Zope templates, on the other hand, has the following strengths - 1) They are designed exactly for taking data and formatting it into markup, so it is much easier to get the markup right and to spot errors. 2) Page maintenance and changes in appearance are easy to do and do not affect the logic used in the scripts that create the data. All you have to do is have your script return the results of its computation in the form of a string, a list, a tuple, or a dictionary. The template can access all the returned data and format it. I have done it both ways - with pretty complex pages - and I can tell you that it is worth the effort to change your mental habits (which is what it takes) to find ways to just return data and not markup. Let scripts do what they do well, and let the templates do what __they__ do well.

acess permission
by Sridevi Vanka 23 May '03

23 May '03

Hi there, I am having problems with acess permissions. I want to control the access of all the data in a particular folder to authorised users only. Basically I do not want anonymous users to even view the dtml documents that are in that particular folder. I unchecked all the permisions to anonymous users in the acl-users folder. but that does not seem to be working. I can view the documents from web interface with out giving login and password. Can some one help me with this? Thanx, Sridevi Vanka __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier. Bingo. http://search.yahoo.com

Newbie: ODBC Error
by Linn, Daniel B - CIEP-3 23 May '03

23 May '03

I didn't get a response, so I'm trying again (and hoping) Searched everything I could before I posted this, but... I am unable to create a ODBC Connection. I fill out the id, the title, and the connection string, but if I have the box checked that says to open connection immediately, I get a 400 Page not found error. It does create the object. I can go to it and it will say the connection is closed. I can go to the properties and change the settings, but whenever I try to open the connection I get the 400 error. Am I missing something? If my connection string is the problem, is this the error I'm supposed to see? Anybody?

Re: [Zope] how to change zport form 8080 to 80?
by J Cameron Cooper 23 May '03

23 May '03

> > >Thanks, where can i find the start script? >i have redhat linux 7.1 system. > > In your Zope install directory, generated by the install script. Right next to z2.py, called start.sh (or start.bat under Windows, I guess.) Add the -w80 flag to the invokation of z2.py (at the very end.) To see the other options you have, do python z2.py -h If you use something other than the zope.org ditribution, you may have a different setup. Find where z2.py is invoked and set -w to 80. Some other options are set by environment variables (see doc/ENVIRONMENT.txt). When Zope starts being distributed with ZConfig (2.7?) then all these configs will probably be set in a config file. --jcc
