User Authentication
by Mayer, Steven 04 Feb '02

04 Feb '02

Hi, soon I have my examination and I must program a product and I will program it with Zope. And for my product I need a User Authentication, I can use the acl-user folder but I must have the e-mail address of the registered user and with the acl-user folder I don´t get the e-mail addresses! Is there an another way? I won´t use CMF I need only the Authentication with E-Mail Address. Thank you for the Answers! :) Regards Steven

Zope-Error: Object of type "None" is not callable
by Sven Rudolph 04 Feb '02

04 Feb '02

Hello to you all! I have a pretty confusing problem :-/ I wrote a product called GMSBericht for publishing news. I started development on zope-2.4.0, and continued working on it through 2.4.2, 2.4.3 and now 2.5.0. The product is refreshable so I don't have to restart the server when I change the python code. Somwhere in the 2.4.2 time zope started to behave strange. When I refreshed my product I was unable to create new instances of it any more. I had to restart the server to be able to create new instances of GMSBericht, until the next refresh. As you can imagin, this makes development rather painfull. When I try to create a new instance of GMSBericht after refreshing it, I get the following error message: Error Type: TypeError Error Value: object of type 'None' is not callable The traceback is: Traceback (innermost last): File /home/sven/zope-2.5.0/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /home/sven/zope-2.5.0/lib/python/ZPublisher/Publish.py, line 114, in publish File /home/sven/zope-2.5.0/lib/python/Zope/__init__.py, line 158, in zpublisher_exception_hook (Object: GMS) File /home/sven/zope-2.5.0/lib/python/ZPublisher/Publish.py, line 98, in publish File /home/sven/zope-2.5.0/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: addGMSBericht) File /home/sven/zope-2.5.0/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: addGMSBericht) File /home/sven/zope-2.5.0/lib/python/Products/GMSBericht/GMSBericht.py, line 169, in addGMSBericht (Object: GMS) TypeError: (see above) Line 169 of GMSBericht.py is in the add function: def addGMSBericht(self,id,title,RESPONSE,REQUEST): """Legt ein Objekt vom Typ GMSBericht an""" handle = GMSBericht() <---This is line 169!! handle.id=id handle.title=title self._setObject(id,handle) if REQUEST.form['submit'] == 'Anlegen und editieren!': RESPONSE.redirect(id+'/editcontent') else: RESPONSE.redirect('manage_main') (Note: GMS is a folder) As you can see, this is just "standard code". And I never changed it since the first version of my product! (Note: My product never had an __init__() function, so "handle=GMSBericht()" executes no code of my own) But after switching to 2.4.2 the described problem appeared and never vanished with 2.4.3 and 2.5.0. I found an old version of my product on my first 2.4.0 installation. I started this server again and tested the behaviour after a refresh, and no error occured. After this I copied the very same source code from $OLDSERVER/lib/python/Products/GMSBericht to a new installation of zope-2.5.0 and the error described above appeared. Then I tested it the other way arround. I took the newest version of my product and copied it to my old server installation, and no error occured after a refresh of my product. Finally I made a new installation of 2.4.0, installed my product (new and old version) and tested the behaviour after "refresh" and no error occured. Unfortunately I need the new features of 2.5.0, so can't just use 2.4.0 (This wouldn't be a real solution). Has anybody encounterd the same problem, or is this a known zope bug? Can anybody help me? Thanks in advance! Greetings Sven Rudolph

ZPT equiv for DTML Command
by Gary Learned 04 Feb '02

04 Feb '02

Ok I have one more question... When setting up a wrapper, the example I'm looking at uses: <dtml-var "_[page_body]" fmt=structured-text> How would this be coded in a ZPT format?

search term in results page
by lambert muhr 04 Feb '02

04 Feb '02

possibly simple, but I don't know how (without using javascript): is there a way to insert the search term, which had been entered in the search form, on top of the results page (like: "you searched for 'search term'; x results have been found") via dtml? thanks for any hint lambert

getPhysicalRoot and <Special Object Used to Force Acquisition>
by Gabriel Genellina 04 Feb '02

04 Feb '02

Hi Inside a Python product, I tried to access another object this way: self.restrictedTraverse('/Folder/Object') This worked fine until this evening, when I got an error 'Object not callable' The error was on Traversable.py, function unrestrictedTraverse, line 166 (Zope 2.4.3 (binary release, python 2.1, win32-x86), python 2.1.0, win32) self=self.getPhysicalRoot() When I printed type(self.getPhysicalRoot), I got: <Special Object Used to Force Acquisition>' (what's that???) This was for a while, I tried several ways to circumvent this problem, and I was happy when I found something that worked fine. But when I tried the original code again to post here, it worked fine (as usual!) and now type(self.getPhysicalRoot)=type <'Python Method'> (as should be, I guess) I swear I didnt change anything but a few lines on my product!!! Nor even restarted Zope, just refreshed my product. And it's my own local install, so nobody else was working at the same server. So I don't understand why it began to fail, and why it suddenly was working OK again... Gabriel Genellina Softlab SRL

RE: [Zope] Anyone using NFGnav?
by Allen May 04 Feb '02

I have the answer!! The problem with my NFGnav session (which I think should be documented) is that the Root Folder security settings didn't have Anonymous allowed to "Reference in NFGnav". I turned that on and it works great.. -Allen -----Original Message----- From: Allen May Sent: Monday, February 04, 2002 2:24 PM To: 'Mike Renfro'; Allen May Cc: Zope (E-mail) Subject: RE: [Zope] Anyone using NFGnav?

Zope Extensions Folder
by Stephan Herschel 04 Feb '02

04 Feb '02

Is there a way to change the way Zope searches for the 'Extensions' folder according to the user ID? - ie/ Is there a way to change this default setting so that it is a sub-directory? I want to use external methods in a module not located in the Extensions folder. Thanks :)
