Page template issues
by Jeff Peterson 15 Jul '08

15 Jul '08

Greetings, I recently upgraded from Zope 2.8.7 to 2.11.0. After working out some issues, everything worked OK for a couple weeks. There were minor page template issues, but they weren't stopping the pages from rendering. Then our server locked up..we had to reboot it. When I got everything back up I get this error: 2008-07-14T11:45:50 ERROR Zope.SiteErrorLog http://dev.bearcatproducts.com:9280/zzz-v2/public/ope/index.html Traceback (innermost last): Module ZPublisher.Publish, line 119, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 42, in call_object Module Shared.DC.Scripts.Bindings, line 313, in __call__ Module Shared.DC.Scripts.Bindings, line 350, in _bindAndExec Module Products.PageTemplates.ZopePageTemplate, line 330, in _exec Module Products.PageTemplates.ZopePageTemplate, line 428, in pt_render AssertionError In all page templates, ported and new. I am running two Zeo servers built from the same base install, and the clients are all built from that install as well. Any clues to what's going on? TIA.

getting post data from a webcam
by William Heymann 15 Jul '08

15 Jul '08

I am trying to integrate a webcamera with a site and I can get it to POST the data to a certain url on the server the problem is I can't figure out how to get access to the data. It is not in REQUEST.form the relevant request vars are ('CONTENT_LENGTH', '111695') ('CONTENT_TYPE', 'image/jpeg') ('HTTP_CONTENT_DISPOSITION', 'attachment; filename="image01-07-29_05-54-26-96.jpg"') This is being posted to a python script object inside zope, however if I need to use an external method that is not a problem I just need to figure out how to get the data. Thanks

Deployment Best Practices?
by Jeff McNeil 13 Jul '08

13 Jul '08

I'm in the process of attempting to migrate a fairly large scale internal XMLRPC system over to Zope. The current system is all custom. That provides for a lot of internal code that we really don't need to be managing. I'm looking for best practices and approaches to deploying Zope 3 instances and a backend ZEO server to share the data. I don't think I've seen it covered anywhere. I've seen it documented from the Zope 2 perspective (both old school and via buildout recipes). It seems this would be a fairly common configuration. Is this stuff covered anywhere? I've been hitting Google up for the last hour or so and I can't seem to find any documentation on deployment and update methodologies. Thanks!

newInteraction error
by Erik Myllymaki 12 Jul '08

12 Jul '08

Hello, I am getting a fair number of these errors popping up: Error Type: AssertionError Error Value: newInteraction called while another interaction is active. I searched for the error mesage and only came up with a reference to Philipp von Weitershausen's book, which I have, but it really doesn't tell me much (while it quite possibly would tell another plenty :). Strangely, the logs do not show this error, but they do have Unauthorized Errors correspondding to the page template that was being requested when the newInteraction error was thrown. Our environment looks like this: Zope Version (Zope 2.10.6-final, python 2.4.4, linux2) Python Version 2.4.4 (#2, Mar 7 2008, 03:56:06) [GCC 4.1.2 (Ubuntu 4.1.2-0ubuntu4)] System Platform linux2 SOFTWARE_HOME /opt/testsite.com/parts/zope2/lib/python ZOPE_HOME /opt/testsite.com/parts/zope2 INSTANCE_HOME /opt/testsite.com/parts/zclient1 CLIENT_HOME /opt/testsite.com/var/zclient1 Network Services ZServer.HTTPServer.zhttp_server (Port: 8050) Process Id 1024 (-1247577200) Running For 1 day 6 hours 12 min 1 sec Any advice greatly appreciated.

ZCatalog : Searching Multiple Indexes : Returning One Result
by Tom Von Lahndorff 10 Jul '08

10 Jul '08

Hi, I have a catalog called "catalog" that contains a bunch of cataloged items. I have indexed 3 properties for each item, "name", "body" and "description". I'd like to be able to search the catalog in the following way: if the word "text" shows up in any index, "name", "body" or "description", return that result back once. The problem is I have is that if a do a search for "text" and say there's results that have the word "text" in one or more of those indexes: catalog({name:query}) or catalog({body:query}) or catalog({description:query}) only gives back limited results (leaves out some 'True' hits) and: catalog({name:query}) + catalog({body:query}) + catalog({description:query}) gives me back the same result 3 times. any ideas? Thanks.

ZCatalog question
by Jonathan Salazar Santos 08 Jul '08

08 Jul '08

Hi everybody I have a method that creates a Files and DTML Documents but I need to Index those news items to a ZCatalog when they are created. Do you know if there are some dtml calls (like manage_catalogACTION) to call the action: Index, Reindex, Delete indexed objects with dtml or Python Scrips. How can I do to get indexed my new items in a zcatalog automatically? Some help will be appreciated. Regards, -- Jonathan Salazar Vista: http://jonathansalazar.com
