This should be easy, but I can't figure out how to do form-based login from the standard acl_users folder. I've played around with acl_users.authenticate(), but can't seem to find something that works. TIA ruger

RE: [Zope] How do reset a dtml-var
by Meilicke, Scott 03 Jun '02

03 Jun '02

variables set by dtml-let are only in the namespace in between the dtml-let tags. When you close the tag, the variables are removed. If you can't use dtml-let tags, you can push the variable into REQUEST with: (not tested) <dtml-call "REQUEST.set('revision','%')"> -Scott -----Original Message----- From: McDonnell, Larry [mailto:lmcdonnell@protonenergy.com] Sent: Monday, June 03, 2002 9:57 AM To: 'Zope@Zope.

Strange error when accessing Zope
by Konrad Hinsen 03 Jun '02

03 Jun '02

After some pause, I wanted to work on my little Zope project again. In the meantime, two things have happened to the machine on which the server is running: 1) The IP address was changed. 2) The machine was rebooted. When I now try to start the Zope server, everything looks fine, but when I then try to access any page, the result is: Site Error An error was encountered while publishing this resource. Resource not found Sorry, the requested resource does not exist. Check the URL and try again. Resource: manager GET with the following traceback information: Traceback (innermost last): File /home/zope/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /home/zope/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 114, in publish File /home/zope/Zope-2.5.1/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: Zope) File /home/zope/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 89, in publish File /home/zope/Zope-2.5.1/lib/python/ZPublisher/BaseRequest.py, line 278, in traverse File /home/zope/Zope-2.5.1/lib/python/OFS/Application.py, line 102, in __bobo_traverse__ (Object: Zope) File /home/zope/Zope-2.5.1/lib/python/ZPublisher/HTTPResponse.py, line 492, in notFoundError NotFound: (see above) What can I do to get my server back into working order?

Generations of websites
by ERIC Lawson - x52010 03 Jun '02

03 Jun '02

I'm considering managing a site, currently 23K files and 1K directories, with Zope. I've perused various Zope resources, among them the Zope Book and sundry How-Tos, but have yet to find clear answers to a couple of salient questions. My hope is that I can get some good answers, or at least some good leads to good answers, by writing to this list. The first and most pressing question: suppose I implement the site using Zope, particularly page templates and DTML. Supposing I need to retreat, then, how can I return to my directory-and-file based site? That is, Zope stores the site as objects in a database; how can I write those objects back to files and directories? Is there an established mechanism for this? Granted, I can whip up some scripts to replace, e.g., <dtml-var standard_html_header> with the standard header, in all files, but.... I'm asking if there is some way to use Zope or a utility to write out the entire site _as it would be served to a visitor_, that is, with all DTML and page template logic replaced. The second, less pressing but still vital question: how can Zope be used in such a way as to preserve the existing URL targets? That is, suppose the current URI is http://www.somesite.com/Documents/reflist/pubCategs/Categories.html, and that URI has been bookmarked by visitors: how, other than a redirection, can that URI be preserved in zope-logic? many thanks, Eric -- James Eric Lawson Research Publications Editor National Simulation Resource eric(a)bioeng.washington.edu - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Whereof one cannot speak, thereof one must be silent. -- Wittgenstein

sort list with ZPT
by Nico de Boer 03 Jun '02

03 Jun '02

Hi all, I want to sort my objectValues('News') at date_add, the date that the News objects were added. I have written a python method to do this: def list_peers(self, sortkey='id'): """returns a listing of peer news objects sorted on sortkey""" itemlist = [] for item in self.REQUEST['PARENTS'][1].objectValues('GNAW'): itemlist.append( (getattr(item,sortkey),item) ) itemlist.sort() return itemlist I can give the sortkey as an argument to the method. When I put the following lines: <div tal:define="itemlist python:here.list_peers(sortkey='date_add')"> <span tal:repeat="item itemlist"><p tal:content="item"></p></span> in my ZPT I get the following output: (<News instance at 92c0e48>, '29 may 2002') (<News instance at 92c0f10>, '30 may 2002') (<News instance at 92c0418>, '31 may 2002') Now I want to implement this in ZPT as follows: <div tal:define="itemlist python:here.list_peers"> <div tal:repeat="item itemlist"> <a href="#" tal:attributes="href item/absolute_url" tal:content="item/title">Title news</a> </div> </div> But I get Undefined Errors. How can I get to the items in the itemlist? Greetz Nico

Accessing a DTML object
by G F 03 Jun '02

03 Jun '02

I am hoping some knowledgeable person out there can help me. I am trying to make a simple little web calendar. The first page that of the calendar is a list of dates that come from a bunch of DTML Documents in a folder called 'events'. Each DTML Document is an event. To do this I use something like: <ul> <dtml-in expr="events.objectValues()"> <li><a href="calendarItem?cal_id=<dtml-varid>"><dtml-var date></a> </dtml-in> </ul> This makes a list of dates that are linked to a DTML Method 'calendarItem'. I pass the variable cal_id to 'calendarItem' so it can display more information about the date. How do i use the variable 'calendarItem' to open the DTML Document into an HTML page? I tried: <dtml-in expr="events.objectValues('DTML Document')"> <dtml-if expr="id == cal_id"> <dtml-var date><br> <dtml-var title><p> <dtml-var sequence-item> </dtml-if> </dtml-in> But for some reason that did not work. It seams that even if it did work there would be a better way. Thank you for your help. Gary __________________________________________________ Do You Yahoo!?

Re: [Zope] Problems with Versions and Zope 2.5.X

O.K. "terrible" was al little too hard. Can you give me a hint to the patch you are mentioning? That would be of great help to me.

"Terrible" might be a little strong in this context, but yes, it's annoying. ;-) Maybe sometime in the future you will be able to mix the two, it's not too hard to fake versions in a storage. I think somebody actually sent me a patch to do this at one point. - C

ZOPE & SSL

Does the Zope webserver have SSL built in? Can I have secured transactions with Zope? How is that achieved?
