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.

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?

(Z)Catalog searches
by richard＠bizarsoftware.com.au 16 Mar '01

16 Mar '01

We're using the internals of ZCatalog to do searching stuff in our Python Product. I've managed to get it working at a basic level by constructing a Catalog instance and adding indexes and calling searchResults(). Only now I need to get into more advanced features, like partial word matches and multiple or'ed search fields. I tried just passing a GlobbingLexicon() to Catalog instantiation, but that completely failed to work. As far as I can tell, it's not using the GlobbingLexicon at all (I put a print statements in all the methods and nothing is printed). I then tried using ZCatalog.Vocabulary(globbing=1) and that didn't seem to work either (still no hits on the GlobbingLexicon methods). Also, any hints as to how to have a "match any" multiple field "or" search would be greatly appreciated. I _think_ I can somehow pass a list of the fields to searchResults() as some sort of argument, but I'm really not sure how.

ANNOUNCE: Zope 2.3.1 beta 2 released
by Brian Lloyd 15 Mar '01

15 Mar '01

Hello all, Zope 2.3.1 beta 2 has been released - you can download it from Zope.org: http://www.zope.org/Products/Zope/2.3.1b2/ Zope 2.3.1b2 contains a number of bug fixes, including the fixes for the issues addressed by the 02/23 and 03/08 hotfixes. It also contains a number of changes to address issues with ZCatalog. New data structures have been introduced to reduce the number of conflict errors caused by object indexing under some types of usage, and to reduce the amount of object database bloat that occurs when indexed objects change frequently. The changes to ZCatalog have been designed so that newly created ZCatalog objects will take advantage of the new data structures. Existing ZCatalog objects will continue to work with the old data structures, but will not gain any of the benefits of the new code. It is possible to upgrade an existing ZCatalog object to use the new data structures by following the How-To at: http://www.zope.org/Members/mcdonc/HowTos/UpgradeToNewCatalog **Users of the Zope source releases should note** that this release contains new C code, as well as a few changes to existing C code. If you are using a source release (or the source diff update), be sure to run 'w_pcgi.py' or 'wo_pcgi.py' as appropriate before starting Zope to ensure that your binaries are rebuilt. For more information on what is new in this release, see the CHANGES.txt and HISTORY.txt files for the release: http://www.zope.org/Products/Zope/2.3.1b2/CHANGES.txt http://www.zope.org/Products/Zope/2.3.1b2/HISTORY.txt Note that we have also posted "diff" updates as .tgz files that will let you easily upgrade an existing 2.3.x site. These updates are available for those currently using the 2.3.x source release or the 2.3.x binary releases. To apply a differential update to your site: - download the appropriate .tgz file from zope.org - shutdown your Zope process - copy the .tgz to your Zope directory and extract it - run w_pcgi or wo_pcgi *if you are not using a binary release* - restart your process Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

manage_main <select ... /> don't work with Mozilla
by Cyril Elkaim 15 Mar '01

15 Mar '01

Hi, The last builds of Mozilla do not accept anymore this kind of HTML tags: <select .... /> I have discuss with Moz developers and they say it's not in the standard. So now we must use something like <select ...>. All the other tags must follow the same syntax, of course. The problem with the management interface of Zope is it uses '/>' in many places. So it's not possible to use Moz for creating new objects for example. So should it be possible to do something about it :-) Cyril

Need Help: Can I use Folder w/Customizer to implement a ImapClient ???
by Ulrich Eck 15 Mar '01

15 Mar '01

hi ZPattern-Freaks out there, i want to write an ImapClient for CyrusImap as Zope-Product. - Handle several Mailboxes - Use Zope-Management for IMAP-Folder-Management and ACL/Security - Use Custom-Interface as Mailclient The Final Structue I want to have. It should act like a standart Zope Folder-Tree: - ImapClient ( holds Connection-Objects toIMAP-Mailboxes, Storage=ZODB) |- ImapRootFolder ( Connection-Object and Root-Folder , Storage=ZODB) | |-ImapFolder (a folder on the imapserver, not persitantly stored) | | |-ImapFolder (..) | | | | ... | | |-ImapMessage (a message on the imapserver, not persitantly stored) | |-ImapMessage (..) |- ImapRootFolder (..) | |-ImapFolder (..) | | |-ImapFolder (..) | | | | ... | | |-ImapMessage (..) | |-ImapMessage (..) after big thougths about whether to use an Implementation like - ZLDAPConnection * A Root Connection Object class ZLDAPConnection (Acquisition.Implicit,Persistent, OFS.SimpleItem.Item,...) * the nodes ar stored in a Tree of Entries class Entry(Acquisition.Implicit,OFS.SimpleItem.Item) or LocalFS does quite the same ... BUT: I want to be able to "skin" every meta_type separately, but I cannot just use Acquisition because of duplicates like "index_html" ------------------- - Use a Specialist AFAIK a Rack can only serve one meta-type It's hard to implement the Folder Structure in racks ------------------- - Use a Folder w/Customizer this pretty looks like the one to use ... but phillip told me some time ago,that I can use it only with persistant ZODB-Storage like other zope-objects - just use Dataskins with factory. So I decided to give it a try. I now have an ImapClient (CustomizerFolder) which stores ImapRootFolder(Dataskin,Acquisition.Implicit,Folder) the RootFolder emulates an ObjectManager to serve the Folders retrieved from the IMAP-Server. The ImapFolder-Objects are stored in an Attribute Children which is a List. and are created like this: def IMAPFolderFactory(client,Name,FullName="", PaddedName=""): handle = ImapDataSkins.ImapFolder(Name) handle._setRack(client.aq_inner.aq_parent._getDataManagerFor(handle)) handle.__dict__['_rackMounted'] = 0 handle = handle.__of__(client) handle.setup(Name,FullName,PaddedName) return handle Now I have an Tree I can browse in the ZMI ... BUT ... "I lose contact to Zope" when i browse down into the first object wich is not persistantly stored. I allthough don't get the "mapped Attributes/Methods" from the Customizer. Is there a possiblity to use the CustomizerFolder with not ZODB-Objects - What Methods need to be implemented that this could work any help appreciated .. don't want to stop halfway ;-) .. thanks Ulrich Eck
