ZPT trials and tribulations
by Phil Harris 16 Mar '01

16 Mar '01

All, I'm in the process of trying out the ZPT stuff(thanks to Duncan Booth for the win32 stuff). Anyway up, It's all going according to plan but I have a few issues, maybe someone has a better idea than me what's wrong here. <code starts here> <?xml version="1.0" ?> <html xmlns:tal="http://xml.zope.org/namespaces/tal" xmlns:metal="http://xml.zope.org/namespaces/metal"> <head> <title tal:insert="here/title">The title</title> </head> <body> <h2 tal:insert="here/title_or_id">the title</h2> <div tal:define="ui python:container.userInfo()"> <b tal:replace="python:ui['dn']">crap</b> <b tal:replace="python:ui['sn']">crap</b> <b tal:replace="python:ui['cn']">crap</b> </div> <hr /> <a href="index_html">click here to refresh</a> </body> </html> </code ends here> The problem is that I'm getting a traceback (I won't bore you with the details unless I have to) to the effect of 'ui' being unknown. If I replace the 'div' in the code above with: <b tal:replace="python:container.userInfo()['dn']">crap</b> <b tal:replace="python:container.userInfo()['sn']">crap</b> <b tal:replace="python:container.userInfo()['cn']">crap</b> then all works according to design, but with a lot more overhead. btw, the userInfo method returns a dictionary of LDAP information, it works in all other contexts, so I don't think the problem is there. Anyone got any ideas? Phil phil.harris(a)zweb.co.uk

ZODB Couldn't load state (Berkeley DB 2..7.7)
by Ping Lau 16 Mar '01

16 Mar '01

I have been using Berkeley DB 2.7.7 as main Zope Storage for about 3 months now. I am running Zope 2.2.4. Everything was fine yesterday. This morning I tried to access a ZClass (base class ZObjectManager), which contains about 2,000 objects, I got ERROR(200) ZODB Couldn't load state for '\000\000\000\000\000\000\026\351' Traceback (innermost last): File /usr/local/zope/2-2/lib/python/ZODB/Connection.py, line 448, in setstate cPickle.UnpicklingError: invalid load key, ''. Other than this ZClass, I can access other objects just fine. I tried Ty's tranalyzer. But it gave me "error: Not a .fs file (at least, not a kind I know about)". How can I recover the 2,000 objects? Regards, Ping

SQL Server ..?
by Bryan Baszczewski 16 Mar '01

16 Mar '01

I am curious of how popular SQL Server is among Zope developers. We have recenly upgraded from SQL 7 to 2000 and noticed most of the database support for Zope centers around Oracle, MySQL, Postgres, Sybase, etc... How many people are using this ZmxODBC database adapter? And what kind of problems/issues/praise do you have? Any info would be appreciated.

ZCatalog Bug?
by Edmund Goppelt 16 Mar '01

16 Mar '01

The bug collector doesn't appear to be working, so I apologize if this issue has already been raised. ZCatalog is failing for me when I attempt to reindex the catalog after adding a keyword index. Zope complains of a name error for Except on line 118 of UnKeywordIndex.py. Here's the code in question: # First we need to see if there's anything interesting to look at # self.id is the name of the index, which is also the name of the # attribute we're interested in. If the attribute is callable, # we'll do so. try: newKeywords = getattr(obj, self.id) if callable(newKeywords): newKeywords = newKeywords() except Except: # ******** Line 118 newKeywords = MV Could the author have meant to write 'Exception' here instead of 'Except'? I am running Zope 2.3.0 stable. -- Ed Goppelt

Hello Juan well, the idea behind me was to do something that anybody can use actually.....if I crack the DateTime module for a quick and dirty, then nobody will benefit from it, and I will have to take care of it in future releases. I was however thinking on two possible solutions: - creating a DateTime class preserving the actual interface while wrapping around mxDateTime.... - pathing the actual one. I will study mxDateTime and think about it. Somebody would like to help me, by the way?

Ola Juan I think that, while on one side is very comfortable to recycle others code, there should have been a very good reason for DC to develop that class. I had the impression that the class is heavily used in the internals of Zope, and probably the integration of an external module would mean a major redesign issue. Always in my opinion, in the long run automaintained code can be easier to leverage and adapt. In the end, if the original developer does not support the code anymore or change it in a way that is not possible to upgrade, DC will have major problems. The idea of developing an internal class is, for me, a good point. However, I think that DC did not approached the international subject simply because, as far as I understood, Zope was build on the American market. While they should be terribly proud of the magnificent product thay have done, in future they will be facing more and more the problem of other countries using it. This is why I am looking to fix the DateTime class starting from their code. This problem will occur also for the formatting of values, for instance. As far as I have seen, when you ask Zope to return a number formatted as currency, you get it in dollars, with the "." and "," used where central europeans put them the other way around. I do not know if DC or somebody else is already approaching this issue, and I admit that I have looked around but I haven't found anything about this, but I am pretty sure that the european developers like me and you which are trying to find a RAD for the internet, will find Zope as one of the best products, and the spread of it will sooner or later raise more and more problems on this side. I was asking this on the ml because I am considering proposing a project on this, but I wanted to be sure that this was not already been done somewhere else Best regards Stefano Vedovelli Hello, IMHO the long term solution would be to use the mxDateTime [1] module instead of the DateTime module that currently uses Zope. best regards, jdavid [1] http://www.lemburg.com/files/python/mxDateTime.html > > Hello > > I am playing around with the DateTime module in order to adapt it to other formats than the American one. However, I would like not to start a work that someone is already doing or that is already done. I have found a little patch that solves temporarily the problem, but I would like to do something more definitive. > > However, I need to be careful due to the large use that is done internally by Zope.

catalog upgrade - what about products which subclass zcatalog
by Ross Lazarus 16 Mar '01

16 Mar '01

I just upgraded my site explicit ZCatalog objects using Chris's very helpful http://www.zope.org/Members/mcdonc/HowTos/UpgradeToNewCatalog instructions - but I have a bunch of catalog aware zclasses and some zclasses which (eg zdiscussions things, based on ZDBase) use Products.ZCatalog - given that the base class has changed, do they need any tweaking to take advantage of the new b+tree code?

Organizing modules in a python product
by Itai Tavor 16 Mar '01

16 Mar '01

Hi, I'm writing a python product containing around 40-50 modules, each one with some dtml files. At the moment I got all the modules .py files in the product directory, and a www directory with subdirectories for each module. Products | -- MyProduct |-- Module1.py |-- Module2.py | www |-- Module1 |-- addModuleForm.dtml |-- Module2 |-- index.dtml |-- Utils.py I want to change this to a layout where all the files for a module are grouped together: Products |-- MyProduct |-- Module1 |-- Module1.py |-- www |-- addModuleForm.dtml |-- Module2 |-- Module2.py |-- www |-- index.dtml |-- Utils.py But I'm finding this very hard to work with. In Module1, importing from Utils require doing 'from Products.MyProduct.Utils', and importing from another Module2 requires 'from Products.MyProduct.Module2.Module2'. Is there any way to set this up so imports like 'import Utils' and 'import Module2' would work in Module1? As a bonus, can I also get __init__.py files in each module directory to be executed?
