Zope Page Template id in python script?
by altkey 21 Apr '04

21 Apr '04

Hi, I have a breadcrumbs python filesystem script. It's a long script that constructs dictionaries and places them in a list for a master_template to display. The dictionaries look like this relative = context.portal_url.getRelativeContentPath(context) obj = portal.restrictedTraverse(relative) .... code for various things ... ordinaryUrl = portal_url + '/' + join (relative, '/') ordinaryId = relative[-1] ordinaryD = { 'id' : ordinaryId , 'title' : obj.title_or_id() , 'url' : ordinaryUrl} In some cases I need to get an id for a zope page template instead of for 'context'. Can anybody tell me how to do that, or better yet tell me where the way to do it is documented? I haven't had much luck searching the source code for something that'll help. [PS: context for the script never seems to include the page template, I understand why but I still want to know which page template is in use when the script is run.] cheers, Phil

RE: [Zope] RAM cache invalidation
by Rauch, Juergen (Juergen) 20 Apr '04

Jonathan, I don't see how this can be done. I am using the Standard RAM Cache manager to cache the results of a couple of scripts(python). I am not writing a new Product, just using zope default components. All I want to do is invalidate all cashed results let's say with a single mouse click. The purpose of this is to give the user a possibility to refresh the view whenever he wants to. This means in between the Cache Managers cleanup_interval. May be a way to achieve this would be to set the cleanup_interval to 0 and then back to the original value. But this seems to be also a kind of sick, if it will work at all. However, thanks for your input Juergen -----Original Message----- From: Small Business Services [mailto:toolkit@magma.ca] Sent: 20 April 2004 16:26 To: Rauch, Juergen (Juergen); zope(a)zope.org Subject: Re: [Zope] RAM cache invalidation From: "Rauch, Juergen (Juergen)" <juergen.rauch(a)optimay.com> > The 'Flush Cache' tap hyperlinks to > 'Control_Panel/Database/manage_cacheGC'. > The StandardCacheManagers don't have a 'manage_cacheGC' function.

If you are working with python products/external methods to implement your application, could you subclass your RAM cache manager to get access to the 'manage_cacheGC' utility? Jonathan

Just because somebody didn't ask for it doesn't mean they wouldn't use it if it was there. I just happened to know that it was abandoned so there was really no reason for me to ask. That being said, I'm not upgrading to 2.7.x precisely because it doesn't have PCGI and I don't have a convenient way of achieving what I want with 2.7.x for one particular Plone site I'm involved in. Yes, I know there are other ways to accomplish what PCGI does. The problem is that I'm not the admin for the server itself and there is a fairly complex authentication scheme in place. The other complication is that the front-end web server isn't Apache (its iPlanet or whatever iPlanet is called these days). That means very little documentation exists to help me. -- Mike

Thanks Jonathan, I am cashing the result of several python scripts. The 'Flush Cache' tap hyperlinks to 'Control_Panel/Database/manage_cacheGC'. The StandardCacheManagers don't have a 'manage_cacheGC' function. At least I couldn't find one. I didn't really make any progress so far. May be I have to extend the interface of the RAM Cache Manager to get this working.

Have a look in the ZMI at how the 'Flush Cache' tab in /Control_Panel/Database works. HTH Jonathan

calling macros

Hi there, I am calling a macro that reference the 'here' variable within python scripts. However the I am calling the macro from within a tal:repeat block. So the here object within the macro is not the object that I want to be working with. Can anyone tell me how I should be doing this so that macro is referencing the correct object. <metal:block tal:repeat="obj folderContents"> <dd> <div tal:condition="python: obj.portal_type == 'News Item'"> <metal:use use-macro="here/newsitem_view/macros/main"/> </div> </dd> </metal:block> Thanks.

Running Zope and ZEO server in one process?
by Gfeller Martin 20 Apr '04

20 Apr '04

Dear Zopistas and ZEOxperts, In our application, we have lots of standard tasks for which one Zope server is adequate, and a few long-running analysis tasks which we would like to delegate to another process, mainly to take advantage of multiple-CPU machines. The delegated analysis tasks would only need read-only access to (a number of) ZODB databases, while the standard tasks modify the databases. I fear that a standard ZEO setup with one storage server, a read-write client, and a number of read-only client would slow down affairs for the main Zope tasks, as there are quite a number of writes (no problem with a single server). Furthermore, it would probably increase memory requirements, as both the Storage Server and the Zope Servers would need substantial caches. Is there a way to run the ZEO server protocol in the main Zope server, i.e., have a single process that is both a Zope server and serves other ZEO clients? Are there other routes I should try? I have also tried to simply open the ZODB DBs read-only from another process, but that doesn't give me the updates to the objects after the initial open. Thank you, and best regards, Martin Gfeller _______________________ COMIT Gruppe Risk Management Systems Pflanzschulstrasse 7 CH-8004 Zürich Telefon +41 (0) 1 298 92 84 http://www.comit.ch http://www.quantax.com - Quantax Trading and Risk System

RAM cache invalidation
by Rauch, Juergen (Juergen) 20 Apr '04

20 Apr '04

Hello community, how can all items in a RAM Cache Manager be invalidated using one single dtml expression ? I found a very cumbersome workaround, which is calling each cached item in a loop like this: <dtml-in expr="cashedItemsFolder.objectValues()"> <dtml-let x=id> <dtml-var expr="'<a href= cashedItemsFolder/'+x?ZCacheable_invalidate:method=Invalidate>'"> </dtml-let> invalidate <dtml-var id></a><br> </dtml-in> this renders to a page that then can be retrieved via "wget" and everyting will be invalidated. But this is not really the solution one would like to have. sth like: <dtml-call expr="myCacheManager.invalidateAll()"> would be way way better. Unfortunately this is science fiction, or is there anything that can do this job ? Any ideas will be appreciated, Juergen
