Creating a ZCatalog to catalog the newly created objects using ZClasses
by kamal hamzat 11 Jun '07

Hello, I was reading and following the zope book to Creating a ZCatalog to catalog the newly created objects using ZClasses while this message was displayed. "ZClasses are a deprecated feature and should no longer be used for new projects. Instead use either through-the-web scripting with Zope Page Templates, PythonScripts etc. or write a Zope product." Please can somebody point me to "How to" for any of these new recommended ways. Thanks.

Automatic Cataloging
by Tom Von Lahndorff 10 Jun '07

10 Jun '07

Hi, I have a zCatalog installed and I'm trying to automatically catalog an object and it's properties using: <dtml-with "manage_clone(base_business,newid,REQUEST)"> <dtml-call "manage_changeProperties( title=REQUEST['business_name'], business_name=REQUEST['business_name'], business_company=REQUEST['business_company'], business_street=REQUEST['business_street'], business_town=REQUEST['business_town'], business_county=REQUEST['business_county'], business_state=REQUEST['business_state'], business_zipcode=REQUEST['business_zipcode'], business_phone=REQUEST['business_phone'], business_website=REQUEST['business_website'], business_email=REQUEST['business_email'], )"> </dtml-with> <dtml-call "zCatalog.catalog_object(business_name,newid)"> The zCatalog has indexes and metadata: business_name business_company business_street business_town business_county business_state business_zipcode business_phone business_website business_email The object does get cataloged with the "newid" but none of the indexes or metadata get updated. Thanks in advance. Tom

Becoming "big" and "slow" are terms that totally sense-free without coming up with numbers and fact. There are real-world Zope installation with millions of objects that are pretty fast. So tell us what "big" and "slow" means and we might come up with some hints instead of responding to a question that isn't worth responding to :-) ---------------------------------------------------------------------------------------------- Thanks for taking your precious time to reply me.

transfer zope security-properties
by Einar Næss Jensen 08 Jun '07

08 Jun '07

I'm on the run for transfering my poorly designed zclasses into real diskbased ones. I've gotten pretty far in only a couple of weeks thanks to this mailinglist and the irc channel on freenet. Thanks everyone! Today I have this question: How can I copy the associated securityinformation about a zclass instance into my new diskbased instance? Roles and permissions. I am using localRoles heavily with my zclasses, and would like this information to be retained also. Any pointers or hints of any kind are very welcome.... Thanks!

RE: Zope 2.9 windows

Hi Chris >I have a customer that using windows xp, The zope server is giving the >following error when starting up > >\zope\lib\python\Zserver\medusa\thread\select_trigger.py, line 133, in >__init__ >a.listen(1) >File "(string)", line 1, in listen socket.error: (10022, 'Invalid >argument') > >Does anybyd have any idea what wrong? It could be related to this problem: * Possible windows+python bug http://groups.google.ch/group/muc.lists.bugtraq/browse_thread/thread/5a605d… They wrote there that this happened with C as well, so, it is not a bug. I know the code posted there is not the same, but it could be a related problem. My best guest is that the problem is related to the Windows Firewall. In mentioned thread, somebody suggested to deactivate it and see if it works. You could also add an exception for the port that zope uses. There are some other suggestions from which I'm not sure, for I usally run zope under linux. 2) Try to run it in an account without admin privileges. I have tested zope with admin privileges under windows without any problem. 3) Disable raw sockets (This is written there, but I have no idea if this can help): Net stop SharedAccess Then start zope and restart the SharedAccess service Regards Josef _________________________________________________________________ Like puzzles?

[Ann] DMHistorical -- access historical state in a ZODB
by Dieter Maurer 07 Jun '07

07 Jun '07

--text follows this line-- "DMHistorical" is a set of tools to access the historical state of a ZODB. Such tools may be helpful to analyse why unwanted or unexpected changes happened and/or to selectively go back to a previous state. This implementation resolves not only the main object but also all (direct or indirect) persistent references from this object at the given time. Zope's 'History' facility on the other hand can show the state of an object at a given time but would resolve persistent references with respect to the current time. This implementation will not work for ZODB 3.2 or earlier. It has been tested with ZODB 3.4. It may (or may not) work for ZODB 3.6 or above.

a batch of inSaNitY!
by Programmer 07 Jun '07

07 Jun '07

Hi I am about to go stark, raving, frothing mad with the DTML-IN batching. Is there a known (or unknown) bug with this? I have searched and read everything I can find about this and no luck. The problem is with carrying the query terms over from one batch page to the next. Right now I am using the script found here: http://mail.zope.org/pipermail/zope-collector-monitor/2003-May/002001.ht ml Except I changed, <dtml-let batch="_.range(100, 180)" batch_size="10" batch_start="REQUEST.get('batch_start',1)"> To <dtml-let batch="myZSQLMethod1" batch_size="10" batch_start="REQUEST.get('batch_start',1)"> The mySQLMethod1 takes two params which the search form supplies to REQUEST. This works great. The pagination works beautifully. However, when I use the very same result script with myZSQLMethod2 (same DB table), which takes 5 params (all optional) the pagination breaks and no-longer passes the query terms. I have checked and rechecked both scripts and both forms. The ZSQLMethods both test good. I am out of ideas. For the life of me I cannot figure out why I'm losing my query terms in one and not the other when the two are almost identical. Care to enlighten me with your collective wisdom? Zope 2.9.6 with mxODBCDA SQL Server 2K PostgreSQL 8.2 Windows XP :-( M. A.
