keeping track of logged in users
by Mario Bianchi 07 Aug '02

07 Aug '02

Hi list, my questions are about logged in users. Let's say I log in to my Zope-builded site as user 'foo' and do something (e.g. navigate around). Now if I ask for a resource (say the bar.html file) to which foo has exclusive view permission granted, I get that resource (view that bar.html file) without Zope asking for authentication credentials. This means of course that Zope automatically checked that the request of bar.html was made by user foo, and also that Zope knows user foo is currently logged in: the question is HOW could it do it? I have disabled the cookies on my browser (Netscape), cleared the disk and memory cache, erased from the file system the directory used by Netscape as the disk cache, so how could Zope tell that the request of bar.html came from user foo? Based on the IP address of the requestor? Also, how does Zope keep track of the users currently logged in? What data structures does it use? More, there seems to be no way of logging out (except if you're a manager: in this case you can use the logout button from the management interface): if you ask for a resource not publicly accessible, you're prompted to enter userid and password and from that moment on you're logged in, but how can you logout?

I just tar my entire zope directory daily, Data.fs and all to tape. Weekly we do an offsite of our tapes.

Apache Rewrite w/o VHM
by Jim Kutter 07 Aug '02

07 Aug '02

Almost NOBODY seems to cover this little problem I'm having. I have a massive site, that must be migrated picemeal to zope. I would like to create virtual urls that pass into zope. I do not want to use virtual host in apache, nor do I want to use proxypass because of problems I've ran into with that. example www.mysite.com -> served by apache www.mysite.com/section_in_zope -> served by zope www.mysite.com/other_section_in_zope -> served by zope if I setup a proxypass so that /section_in_zope/ goes to www.mysite.com:8080/section_in_zope (which works), all my links (file.html) now go to www.mysite.com:8080/section_in_zope/file.html. So i set a siteroot for section_in_zope, with base http://www.mysite.com/section_in_zope/ and base /section_in_zope/. The problem with that is now the link file.html goes to http://www.mysite.com/section_in_zope/section_in_zope/file.html and it grows with each new link. So basically I suspect rewrite will be my answer. How would I go about setting up both apache and zope to do that? -jim

RE: [Zope] Zope Troubleshooting Tip (learn from my mistake)
by Schmidt, Allen J. 06 Aug '02

Thank you! Thanks you! Thank you! Another big plug for the open source community! This is exactly the problem we were having and pounded our heads over it...and it is really so simple when you think about how Zope works! How can one block that out so easily?? But I guess life is like that...the simple things sometimes are staring you right in the face. Thanks BZ!!! -Allen -----Original Message----- From: zope-admin(a)zope.org [mailto:zope-admin@zope.org]On Behalf Of BZ Sent: Tuesday, August 06, 2002 6:28 AM To: zope(a)zope.org Subject: [Zope] Zope Troubleshooting Tip (learn from my mistake) So I was trying to get ZUBB to work (yes, I am the person maintaining the code as well) and for some reason I could not post to this one board I had installed in a virtual host/cmf. I created another board and nothing would post. I checked permissions, locations, everything and it would not post. After hours of playing with it and getting quite frustrated I remembered a problem I once had with names so I searched my installation for "post" but got back nothing but the two post methods in my first and test boards. And then I saw it. Sitting right there in the root directory. A folder named "submit". I renamed it "submit_old" and lo and behold I could post again. The problem was that I was checking for "submit" in my post method and it was picking up on the directory name (OO and all that goodness). TIP: The lesson learned is: When troubleshooting something in Zope make sure you are not calling a method or variable that has the same name as another method / variable / object in your folder paths. Use the find feature and take a look around.

Re: [Zope-dev] passing variable between zope and asp
by felix＠chaptereight.com 06 Aug '02

Hi Faye Have you thought about: - using HTTP POST rather than stuffing it in the url? - XML-RPC For both the above, running it over HTTPS would be more secure obviously. If both sites are running on the same server, you might be able to do something locally, either using the local filesystem, or again over HTTP to localhost. Felix. P.S. I've CCd the zope users mailing list - I think it's probably more suited to this question.

Thank you. :) Actually I have found that to be a useful pattern and use it a lot. It means the form is encapsulated in one (dtml-enabled) zwiki page, which I find more convenient to edit and maintain than having a pythonscript handler. Here's some examples - http://zwiki.org/ZwikiAnalyzer http://zwiki.org/UserOptions http://zwiki.org/ZwikiAndExUserFolder http://zwiki.org/SearchPage I hope details of how some particular pages do their thing doesn't deter coders from getting into zwiki hacking. Their DTML isn't pretty - it was the simplest thing that worked - but it's localized. They can be cleaned up any time someone gets the itch. -Simon

Using Classes in Python scripts
by Andreas Tille 06 Aug '02

06 Aug '02

Hi, I just want to hold some data structures in the session data. The application I want to write gatheres data from a database according to several options which can be set in a several step menu system. I have to keep track to the options. After reading /Examples/ShoppingCart of the Zope hierarchy I tried to adopt this scheme of data tagged by keys in the session data but I found out that I lost overview about this stuff if I would dive deeper into the data structure I would need. I thought I would find the solution in defining my own class variables and found out that this is not possible in Python scripts for security reasons. Next I tried External Python methods but I've got strange effects with this approach and I think it would not work as well. I thought I would find the solution at http://www.zopelabs.com/cookbook/991933953 but I just got an error right in the first line of the example code: Zope has encountered an error while publishing this resource. Error Type: ImportError Error Value: import of "Products.PythonScripts.Utility" is unauthorized So I have two questions: 1. Is this the right approach to accumulate several data in the session variable even if there is a more complex menu structure of options which are sometimes dependand one from some others. 2. If yes what is the best way to get this working. Kind regards Andreas.
