"Finding"a bunch of DTML Documents into a Zcatalog is easy. But how to do that programmatically? I haven't even found a way of doing that for a single DMTL Document. -- Wolfgang Strobl

Zope for medium/large sites
by Tiago Antão 05 Nov '00

05 Nov '00

Hi! We're considering using zope for a somewhat large project: It's a VPN for arround 10.000 institutions ( >100.000 users expected, up to 1.500.000 users possible, but not likely). Hundreds of simultaneous connections expected. The database has to support >100.000 users and a LOT of content (more than 1000 virtual hosts, along with a very big main site). The question is: Is zope up to this? And yes, the necessary hardware is available 8-). We've used Zope for smallish internal projects, but for something as this... Best regards, Tiago

Kindest.. Of course I did something wrong. ;) I need to disable the SiteRoot i implemented.. because right now all is /&#% up.. ;) Have you got any information about this? I am running this startup script as of now.. but it does nothing (esp. thinking of the env. variable that was stated on www.zope.org) #! /bin/sh #exec 2>&1 SUPPRESS_ACCESSRULE=yahoo export SUPPRESS_ACCESSRULE PATH=$PATH:/usr/local/bin PYTHONPATH=$PYTHONPATH:/usr/local/lib/python1.5/site-packages reldir=/usr/local/zope/Zope-2.2.1-solaris-2.6-sparc/ PYTHONHOME=`cd $reldir; pwd` export PYTHONHOME export PYTHONPATH exec /usr/local/zope/Zope-2.2.1-solaris-2.6-sparc/bin/python \ $PYTHONHOME/z2.py \ -a 'localhost' \ -u 'zope' \ -m '' \ -f '' \ -p '' \ -F '8989' \ -d '' \ -w '' \ -D \ -Z '' "$@" Would apriciate any input! Kindest, Jørgen Skogstad

Problems with LoginManager 0.8.8b1
by Jeff Hoffman 05 Nov '00

05 Nov '00

Hello, I am having an odd problem with LoginManager 0.8.8b1 and am writing the list in the hopes that someone can either help me out, or confirm that I've encountered a bug. I am running Zope 2.2.2 with Python 1.5.2 on a Linux box. I installed LoginManager as described, and compiled DynPersist and so forth for ZPatterns. All seems to be working well. I created a temporary folder called 'sandbox', inside of which I instantiated a LoginManager. In its UserSource (a Generic User Source), I created four Python Methods (with Python Methods v0.1.7): --- userAuthenticate <params>self, REQUEST, username, password</params> if username == 'XXX' and password == 'XXX': return 1 else: return 0 --- userExists <params>self, REQUEST, username</params> if username == 'XXX': return 1 else: return 0 --- userDomains <params>self, REQUEST, username</params> return [] --- userRoles <params>self, REQUEST, username</params> if username == 'XXX': return ['Manager', 'Member'] else: return ['Member'] Once done, I pointed my browser to http://myhost/sandbox/index_html. This method is a standard DTML Method, inluding standard_html_header and footer and putting some text in the middle. I get the following error: Traceback (innermost last): File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: index_html) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: index_html) File /usr/local/zope/lib/python/OFS/DTMLMethod.py, line 172, in __call__ (Object: index_html) File /usr/local/zope/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: index_html) KeyError: standard_html_header Zope can't find standard_html_header. I am guessing the acquisition path is getting hosed somewhere along the way. If I simply delete acl_users from sandbox (my LoginManager), index_html works fine. Moreover, it is not just standard_html_header that I can't acquire. I created a DTML Method called foo, and could not acquire it, either. Any ideas? --Jeff --- Jeff K.

university portal
by Lee 05 Nov '00

Hi, I'm another Zope newbie with a few questions. My appologies if this message is being sent to the wrong mailing list. I'm a final year student doing a project to create a course/personal management system for my university. I understand there's quite a lot of similar work going on in this field already. I aim to create a database to store student information in (using mySQL or Zope?) which the user (the lecturer) can add content to (details of grades, etc) via a web browser and use for bulk manipulation of data... sending email amongst other things. In addition, I hope to provide a 'wizard' (in a browser window) to provide facilities for uploading lecture material, news, etc. to the course web page. Going through Zope's 'Elvis' tutorial this seems possible. [Q] Is it possible to present a user with various web forms to input information (say, a news article with headline & content) that once submitted will be displayed on the page in a suitable format? I think Zope is capable of this... is Python/anything required. Are there any examples I can look at? I am in the process of reading the online Zope book - if anyone has any advice for reading material, I would be grateful to hear it :-) [Q] There are a lot of Zope products available - am I right in thinking that, say a 'Zope Discussion Board' product, could be download and integrated into a Zope-powered web-site? i.e. Are Zope products 'plug and play' TM? ;-o Thanks for the bandwidth, Lee

[ANN] Zope 2.2 patch for cDocumentTemplate/Acquisition bug
by Dieter Maurer 05 Nov '00

05 Nov '00

Appended is a patch for the cDocumentTemplate/Acquisition bug. Usually, this bug manifests itself by an "AttributeError: __call__" for a folder object. The usual context is: DTML Document: ..... <dtml-with folder>  .... </dtml-with> ..... The patch modifies "C" code. This means you need a Zope source distribution to apply it and then you must regenerate Zope. Almost surely, the patch is not yet complete: The code in "cDocumentTemplate.c" looks like (Python emulating "C" code): if callable(o): if hasattr('isDocTemp') and o.isDocTemp: o= o(None,md) else: o= o() The remaining problem is that 'isDocTemp' might be acquired and does not belong to "o.__call__". In this case, "o" might be called with the wrong number of parameters. I would expect, that the problem disappears, when the "isDocTemp" test is performed with "o.aq_base" rather than "o". But I am not sure. Maybe, an acquisition expert can look into this remaining issue.

Re: [Zope] Obtaining just the filename for multiple file fields in an add form form
by Dieter Maurer 05 Nov '00

Darin Lee writes: > ... accessing the name of an uploaded file ... This is an FAQ (--> searchable archive). Uploaded files are "ZPublisher.HTTPRequest.FileUpload" objects. From their source documentation: File upload objects are used to represent file-uploaded data. File upload objects can be used just like files. In addition, they have a 'headers' attribute that is a dictionary containing the file-upload headers, and a 'filename' attribute containing the name of the uploaded file. Dieter

Re: [Zope] Question about dtml-in
by Dieter Maurer 05 Nov '00

05 Nov '00

Sean McGrath writes: > ... "dtml-in" treats sequences of two element tuples specially ... You are right. This is to support the frequent case of iterating over item sequences. There should be a "dtml-in" argument to switch off this special treatment. If I had your problem, I would go for such a solution (extending "dtml-in"). It should be easier than to work around the special treatment in DTML and it would help the Zope community as a whole. If you do not want to go this way, I would suggest to put a feature request into the Collector. Dieter

You already looked at the Zope "UserManagement" documententation? E.g. in the upcoming Zope book? > I am also wondering if anyone has been able to tie authentication into > a unix passwd file? There are lots of UserManagement products around. Maybe, this is covered. Search "zope.org". A "PAM" based user management product might do what you have in mind. Dieter

Are you interested in the "id" of "x"? Then the best thing is: <dtml-with x> <dtml-var id> </dtml-with> Dieter
