Session Management
by Gerardo Amaya 26 Aug '02

26 Aug '02

Hello all. I'm new in all this Zope concept and products. I'm building a site that requires user control and management all over it. What I need is to keep track of my user in the website, he logs in and I have control of what he can see, do, or can't. Is there an easy way in Zope to implement this, I mean like a product or something. If this is not the case what function in python can help me to accomplish the task. I'm looking for something like PHP sessions and sessions variables. But if there is some other way(a better one) I welcome your suggestions. Thanks in advance Gerardo Amaya

Did I fsck'd my Products installation?
by Carlos A. Carnero Delgado 26 Aug '02

26 Aug '02

*This message was transferred with a trial version of CommuniGate(tm) Pro* Hi, I think that I just fscked my Windows Zope installation :| Can anyone tell me if there's a default (read basic plain Zope installation with only the 2002-06-14 Hotfix applied) __init__.py in lib/python/Products? If there is one, can anyone send me his/hers? (just in case, running Zope 2.5.1 + Hotfix-2002-06-14 for Windows.) Ah, that reminds me a question: can I see--inspect, download--the cvs repository (http://cvs.zope.org) "filtered" with a tag or release? Like, show me the repository for, say, 2.5.1? Thanks a million, Carlos.

RE: [Zope] redirect strangeness ...

Thanks Charlie, but it's the other side of the dtml-if that's failing. The side that uses marshallwormvar() works fine. It's the unadorned redirect to index_html that rises the exception. >"Charlie Reiman" <creiman(a)kefta.com> wrote in response: > >I can't say specifically, but %3A is ':', so I'd guess marshaformvars() is >returning something with a ':' in it, which might confuse the browser.

Linux, Page Templates and XML
by rra42 26 Aug '02

26 Aug '02

Hi Everyone, XML Zope Page Templates on Linux Zope 2.5 will not work for me. Trying to save a newly created XML page template results in pyexpat module not found. I've looked at the source and I've tried reinstalling ParsedXML in the location where ZPT expects to find it, but the build of ParsedXML fails with an error which looks as if it is in the Makefile.pre.in for ParsedXML.. Has anyone got XML page templates to work on Zope 2.5 on Linux? It appears to work fine on Windows. Thanks, Rob ________________________________________________________________________ Want to sell your car? advertise on Yahoo Autos Classifieds. It's Free!! visit http://in.autos.yahoo.com

redirect strangeness ...
by Dennis Allison 26 Aug '02

26 Aug '02

This dtml fragment fails strangely --- <dtml-var standard_header_html> <dtml-if expr=pythonscript()> <dtml-call expr="REQUEST['RESPONSE'].redirect('index_html')"> <dtml-else> <dtml-call expr="REQUEST['RESPONSE'].redirect('originalform?'+marshallformvars())"> </dtml-if> <dtml-var standard_footer_html> The pythonscript() validates the form variables. marshallformvars() is a python script that returns the appropriately quoted name/value pairs. The observed behavior is strange. If the pythonscript() returns 0, the transfer to the originalform occurs along with the diagnostic information inserted by the validation script. This is the behavior I expect. But when the pythonscript() returns 1, I get a Zope error indicating that the sytem cannot find, not index_html but /aaa/bbb/ccc/ddd/%3A Both the index_html and the failing dtml-method are in the folder referenced via the path /aaa/bbb/ccc/ddd. As a workaround I replaced the first redirect with a <dtml-var index_html> but I do wonder why the initial approach failed. Insight appreciated. -dra

installation problem
by Scott 26 Aug '02

26 Aug '02

Hello I'm trying insall Zope on Mandrake 8.2. When I run the ./install command I get the error message "There were errors during Python module compilation." I thought that this this might be because I already had a version of python installed so I uninstalled the version I already had. I still get the same error though. Does anyone know why this would happen? Thanks, Scott

Security Permission Settings
by rruth＠computer.org 26 Aug '02

26 Aug '02

What permissions do I set in the security tap to do the following: I have two dtml methods. The first one, 'validate' I want anonymous users to be able to access in the default manner. The second dtml method, 'query', I want to be called from the first dtml-method, 'validate', but never directly by an anonymous user. (ie. the anonymous user can connect to: http://...validate but will get an error for: http://...query) How do I set the permissions of the second dtml method, 'query' to do this?

DTML - DateTime not allowed to access

Hi, please help a stupid blind man. I installed Zope 2.5.1 (not my first Zope installation) on Linux. I got some nasty errors when I installed my application. One error I traced down to <dtml-var ZopeTime fmt="%d"> giving Error Type: Unauthorized Error Value: You are not allowed to access %d in this context Why can't I fmt the DateTime objects any longer?
