Help needed with LoginManager and REMOTE_USER authentication
by Jay, Dylan 16 Nov '00

16 Nov '00

I want to use REMOTE_USER authentication so that I can authenticate people using IIS NT authentication intergration. IIS is set up and passing the correct REMOTE_USER to Zope. I set up LoginManager with a GenericUserSource. Now I figure I want anyuser that can pass the IIS security to be a user, ie no presistant list of users I want to check against. I figure I can do this by creating pythonMethods for userAuthenticate and userExists which both return 1. I did this but every time I try to access a page protected by the LoginManager I get the following error "Sorry AUSLABS\dylanj, you are forbidden to access this resource." saying that the GUF stuff is probably not working. Anyone with any ideas whats wrong or with a better way to do what I want? The problem I seem to have is that when I activate the GUF user source I lose management access to the LoginManager object. If its not working and therefore not authenticating me then shouldn't use aquisition to find a acl_user folder lower down to authenticate me and therefore let me use the management interface like normal?

zlib.error : huh?
by Aaron Straup Cope 16 Nov '00

16 Nov '00

I am trying to understand what exactly is going on when Zope returns an Error -5 page. Normally, this only happens on the left hand navigational menu but today it happened while I was expanding an xml document/tree object from the Examples package for the XML Document product. I've tried searching Google, the Zope site and the mailing list but to no avail. Could someone please explain what's going on here? Is it me? Is it Zope? How exactly do I prevent these errors from happening? Thanks, Error Type: zlib.error Error Value: Error -5 while decompressing data: [] Traceback (innermost last): File /usr/local/zope.old/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/zope.old/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope.old/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/zope.old/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope.old/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: tree) File /usr/local/zope.old/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: tree) File /usr/local/zope.old/lib/python/OFS/DTMLDocument.py, line 177, in __call__ (Object: tree) File /usr/local/zope.old/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: tree) File /usr/local/zope.old/lib/python/TreeDisplay/TreeTag.py, line 154, in render (Object: test[0]) File /usr/local/zope.old/lib/python/TreeDisplay/TreeTag.py, line 229, in tpRender (Object: Manageable) File /usr/local/zope.old/lib/python/TreeDisplay/TreeTag.py, line 637, in decode_seq zlib.error: (see above)

Uploading files
by Nolan Darilek 16 Nov '00

16 Nov '00

I'm trying to write a replacement form which allows users to upload images into a folder. I'm almost there, but not quite. I'm having difficulties getting the file contents into the database. I have an <input type="file"> field, and I'm fairly sure that the data is being sent. When I create the Image however, I use file=REQUEST['file'], and the resulting image stores the path to the file, instead of the file contents. So, given that I've uploaded a file, and that its name is in REQUEST['file'], how do I get at its contents when creating the Image?

Catalog sort-on parameter
by Menard.Jean-Francois＠hydro.qc.ca 15 Nov '00

15 Nov '00

I'm trying to use the 'sort-on' parameter in a Catalog search, and it doesn't work. I use Zope 2.2.2. I read in pasts messages that the 'sort-on' feature was broken, is it still ? I'm not sure if I use the right syntax so could someone post an sample code here please ? Thanks!

FYI: Digital Creations secures $12M round of investment
by Paul Everitt 15 Nov '00

15 Nov '00

Hello Zope friends. At long last we at Digital Creations are able to publicly say it: we've closed a $12M round of investment: http://www.digicool.com/News/CRound.html It's out on the newswire now. We'll start pushing it out more over the next 24 hours. This, needless to say, is a big deal, one that we've worked on really, really hard this year. With the tech market downturn since March, and with Open Source particularly getting a beating, it's vindicating to get good funding from strong partners. When everyone else was getting wads of cash during the go-go times, we were quietly at work, being frugal, making money, making a business case, and being profitable. We're proud to say that we got our money when money was hard to find. Let's put it this way: Open Source business is hardly dead. It's just different, and better. What will this mean? First and foremost, Zope and Digital Creations will become very competitive, very quickly, along a number of axes. As the PythonLabs move indicated, we are taking aggressive steps to become a dramatic force in the worlds of content management, web application services, and Open Source leadership. With this round, our business model has been validated. As a member of the Zope community, I view this as "the dream delivered". Many of us care deeply about this thing we're involved in, and sometimes it feels like a longshot. Though this is still a David vs. Goliath, David now has a slingshot, and a bit of steel in his eye. Thanks go to the folks here at DC, to the Zope and Python communities, and to the companies around the world that are basing their business on Zope. Onward! --Paul

structure text named link hassles
by Karl Anderson 15 Nov '00

15 Nov '00

I'm having a hard time making proper named links using Structured Text (in a ZWiki). Each of these formats produce the proper link (to the remote URL), but the valid link is followed by the ? link to create the wikiname in the quotest (including the colon). I don't want to cause confusing for someone who mistakenly thinks they can or should create the relevent page, and I do want to use the RemoteWikiLink format for clarity.

How to separate markup from presentation
by Tom Sheffler 15 Nov '00

15 Nov '00

I'm aware of HiperDom, but I'm wondering if anyone has a good suggestion for how to structure docs so that docs can be written using abstract tags whose definition is separate. What I've done is a simple variable substitution. My doc uses constructs like <dtml-var MyH2Start> ... content ... <dtml-var MyH2End> and the definitions of MyH2Start and MyH2End are simple properties, whose values are usually something like: MyH2Start = "<td class=MyTdClass><P class=MyTagP>" MyH2End = "</P> </td>" This is the first part of the problem. Additionally, I would like the definitions of my tags (MyH2Start and MyH2End) to be dependent on the context in which the content appears. (If it shows up in a sidebar, an H2 looks one way, rather than in a main page where is looks another way.) (These were issues that CSS were to address, but most implementations are incompatible.) I'm not looking for a product as much as a suggestion for a methodology. Any help appreciated. T 7om

Re: [Zope] Where to store my data?

To clarify what I meant, while there's nothing wrong with XMLDocument, there are many other ways to do this, too, if XMLDocument isn't suitable. For example, you can output XML with Python or DTML that walks your data, and not have to constrain how you're storing it. -- Karl Anderson karl(a)digicool.com

How to mix perl and dtml
by Schut, Koos (Koos) 15 Nov '00

15 Nov '00

Hi all, Situation: I have a fairly strong background in perl. I've lots of custom perl-tools on an Informix-database unix-machine on which I have the zope web-server running now. What I want is to create some web-pages, displaying information as distilled from the database. This destillation, I can do easily with perl. I view the zope web-pages from a different PC. Questions: How do I create a zope method to actually run a perl destillaton-process and have the result in a Zope web-page? What I can do is write perl-scripts which even create html-code. What I do not know is how to call the perl-stuff from a zope-page, and get the results in a zope html-page. Reading the different docs, it is clear that it should be possible. Can anyone give me some clever hints here? Cheers, Koos. J.J.
