hi all, select_all_from_myTable refers to a Z SQL Method that queries via a 'GV Interbase Database Connection' object an Interbase database >> <dtml-in select_all_from_myTable> >> <p><dtml-var expr="myFunction(<dtml-var myField1>)"></p> >> </dtml-in> Patrick Lewis <plewis(a)inetarena.com> answers: > You fell for the old "nested dtml" trap.

The result was that Zope asks me for authentification, that failed even with a valid user who has manager and owner rights. cu & thanx.

Calling a dtml-method that has an extension (Was: Re: [Zope] Creating files on server)
by Gitte Wange 25 Apr '01

25 Apr '01

Hi again, For secure reasons I have dropped the idea of creating a physical file on the server. Instead I can create the files dynamically inside Zope and link to the method. I have a method called fncSmileGenerate.smil I call this from another method. Now when doing this I get the following NameError: Error Type: NameError Error Value: fncSmileGenerate The traceback is this: Traceback (innermost last): File /usr/local/Zope-2.3.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/local/Zope-2.3.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/Zope-2.3.0-linux2-x86/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/Zope-2.3.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/Zope-2.3.0-linux2-x86/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: index_html) File /usr/local/Zope-2.3.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: index_html) File /usr/local/Zope-2.3.0-linux2-x86/lib/python/OFS/DTMLMethod.py, line 189, in __call__ (Object: index_html) File /usr/local/Zope-2.3.0-linux2-x86/lib/python/DocumentTemplate/DT_String.py, line 538, in __call__ (Object: index_html) File /usr/local/Zope-2.3.0-linux2-x86/lib/python/DocumentTemplate/DT_With.py, line 146, in render (Object: portal_properties) File /usr/local/Zope-2.3.0-linux2-x86/lib/python/DocumentTemplate/DT_With.py, line 146, in render (Object: admin) File /usr/local/Zope-2.3.0-linux2-x86/lib/python/OFS/DTMLDocument.py, line 182, in __call__ (Object: index) File /usr/local/Zope-2.3.0-linux2-x86/lib/python/DocumentTemplate/DT_String.py, line 538, in __call__ (Object: index) File /usr/local/Zope-2.3.0-linux2-x86/lib/python/OFS/DTMLMethod.py, line 182, in __call__ (Object: dspDisplayShow) File /usr/local/Zope-2.3.0-linux2-x86/lib/python/DocumentTemplate/DT_String.py, line 538, in __call__ (Object: dspDisplayShow) File /usr/local/Zope-2.3.0-linux2-x86/lib/python/DocumentTemplate/DT_In.py, line 713, in renderwob (Object: sqlGetShowClips(showid=showid)) File /usr/local/Zope-2.3.0-linux2-x86/lib/python/DocumentTemplate/DT_Util.py, line 334, in eval (Object: fncSmileGenerate.smil(clipid=clipid)) (Info: fncSmileGenerate) File <string>, line 0, in ?

Re'f. : Re: [Zope] Running zope on port 80
by Francois-regis Chalaoux 25 Apr '01

25 Apr '01

As you can read in z2.py : # User id to run ZServer as. Note that this only works under Unix, and if # ZServer is started by root. UID='nobody' This is not effective on NT server. Thus, could somebody tell me Howto to start Zope as 'root', choose the UID when zope switches identity to a user specified at installation. I suppose with your answer I should be capable to 'mount' a NT network volume in Zope with LocalFS. Cheers, FR.

Re: [Zope] asp request and response objects

Hi Chris, I actually stumbled upon your Enlightenment posting a few days ago - found it not only helpful, but representative of the sort of movement thats needed/required in the space in which we work. Zope can really make alot of what we do so much more fun than the Microsoft way. Your posting was quite inspirational and honest - and reflects well on the ethos behind Digital Creations, Zope and all of us involved - past present and future. Call you a Zope evangelist or just plain helpful. Either way I hope to interact with you more as I strive towards complete enlightenment.

jcNTUserFolder problems
by Erik Myllymaki 25 Apr '01

25 Apr '01

I am using Zope2.2.0 on WinNT. I have added jcNTUserFolder0.1.1 but can't get it to work. On the Detailed view, all the usernames for the Default Domain show up as "Broken User Domain\Username". On the Contents Tab, users form the Domain show up but I get an error message like: Error Type: AttributeError ErrorValue: 'None' Object has no attribute '__' Zope is running under a user that has permission to: run as a service, logon to the machine over a network, act as part of the operating system. Any help appreciated.

Re: [Zope] Bad File Descriptor error - zope crashes at startup

A system crash last night and now Zope starts ok, but quits > the moment I try to access it from a browser request:=> > > self.file.flush() > IOError: [Errno 9] Bad file descriptor Looks like a severe problem. I guess that crash has damaged some essential infrastructure, the socket library, a Python module or a ".pyc" file. I would save my "var/Data.fs" (maybe install on the Linux system, to see it works). Then reinstall Zope, if necessary Python, and see whether things improve. The next reinstallation would be the socket library maybe Windows.... Dieter

RE: [Zope] asp request and response objects

Thanks Tom and Tino. I do believe that Zope and Python is a fantastic combination for building web based applications and systems. I agree that a new way of thinking is required to go to a complete OO web development mentality. I found myself taking 2 hours to figure out to RE-CONSTRUCT a folder to store IMAGES and then give pages outside that FOLDER access to them for display... Typical images folder you see with sites... This alone - when you have zo-db behind you doesnt make sense to structure your applications the same old way. Everything is an object - everything stands on its own. Then its just a matter of structuring your directories for complete productivity purposes at higher/broader level or keeping things really flat. ASP - leaves you limited to how you can approach a problem. Its easier to learn because of this. But, in the end makes for very UN-ELO-QUENT solutions. Zope is more impressive in terms of not just focusing on mundane things, but really going behind 2 or 3 core objects and making the web application world really open up! I like that phrase - 'developement "the zope way"' - would look good on a tee-shirt? Has anyone put any effort into a resource that documents the bullet points of what that means - developement "the zope way"? I would be willing to do so - to really point out to other developers (ASP etc.) Why Zope rocks and __blank__ doesnt! We could fairly deep into it - not just high level reasons why its better... Just a thought. The thing I find the clunkiest (though it works flawlessly and makes good intuitive sense) is the management interface. Would be better as a rich gui. This work is going on isnt it already?

URL quoting from a Python script
