ZCatalog and SiteRoot Not Getting Along
by Edward Pollard 14 Feb '03

14 Feb '03

Previously I came to the list with a problem of entries in the ZCatalog going away when I hit the "Update" button in the Catalog "Advanced" tab (Subj: [Zope] ZCatalog - Full Update Deletes Valid Entries). Well, I figured that the problem is caused by the presence of a SiteRoot. (I develop on a server without a siteroot, thus the problem did not arise in development.) I'm resubmitting this problem so that perhaps someone with greater wisdom than I can set me on the right path -------------- First, "The Preamble". Stuff you need to know to understand the context of my problem. Our main website is http://www.blah.ca We use Apache ProxyPass to redirect certain directories to directories on our Zope server. ie, http://www.blah.ca/notice is not redirected, http://www.blah.ca/it goes to http://zope.blah.ca/www/it Indeed, all zope pages served this way are in the /www/ directory. We also proxy pass /manage et al so we can manage the material behind the site root. We've developed a system for indexing websites - zClasses that extend Page Templates and File that are catalog aware. Sitting at the root of the /www/ heirarchy is the zCatalog that runs this show. I have webtools to create and manipulate the zClassses mentioned above. I've also created the correct PropertySheet methods to change the cataloged information in the ZMI. ------- Now, "The Problem". I create some of my zClass objects at http://www.blah.ca/it/. This is, really, at http://zope.uleth.ca/www/it/. They show in the zCatalog with Object Identifiers in the style '/it/filenames'. Fantastic. I can manipulate them every which way from sunday. No trouble. They display in my zCatalog search tool properly. I go to http://www.blah.ca/myzCatalog/manage. I look on the Catalog tab and see all my items as they should be - all with identifiers starting with '/it/'. I go to advanced. Hit Update. Go back to Catalog. All gone. I go to Find Objects, and select my zClasses (all items of these classes should be in the catalog anyway). They all come back, but now their identifiers are /www/it/filenames. If I try now to manipulate these files - change titles, for instance - when they reindex they do not recongize the entry in the zCatalog with /www/ in the identifier as their own, and create a new entry. The item is now listed twice. - once with an identifier beginning with /www/ - once with an identifier beginning with /it/ The /it/ entry will now behave as I would expect it to. The /www/ entry never gets changed - not when I update with my tools, not when I change properties in the ZMI. It only becomes accurate when I update the index again, and all the /it/ entries are deleted. So, it seems clear that the zCatalog and the SiteRoot are not getting along. Anyone with any experience to set me right, or can I not use the ProxyPass system when a zCatalog is present? Thanks, Edward

Aquisition

Hello Folks, I am developing an Page Template that should create a link depending on the content of that folder. If I find an index_html, I want a Link otherwise not. I have a Python Script check4index_html: return hasattr(context.aq_explicit,'index_html') and the following PageTemplate: <a tal:condition="python:r.object.check4index_html()==1" tal:content="r/object/title_or_id" tal:attributes="href url" target="main">Id</a> For some reasons the condition evaluates to true all the time. The script works fine and the objects are valid ( I see the right title). So what is wrong ? Thanks for any ideas....

Logout: Prompt pops up again
by Thomas Guettler 14 Feb '03

Hi! If I use the logout method like this: def logout_(self, REQUEST, RESPONSE): """ Logout current user Stolen from: App/Management.py """ p = getattr(REQUEST, '_logout_path', None) if p is not None: return apply(self.restrictedTraverse(p)) realm=RESPONSE.realm print "realm:", realm RESPONSE.setStatus(401) RESPONSE.setHeader('WWW-Authenticate', 'basic realm="%s"' % realm, 1) RESPONSE.setBody(self.logout(refresh=0)) return The browser pops up a prompt where I should login again. But I login into the logout page which is senseless. Has someone a solution? I tried a redirect to a public method but this does not work. thomas -- Thomas Guettler <guettli(a)thomas-guettler.de> http://www.thomas-guettler.de

CMS Architecture Ideas/Help
by JBeard＠porternovelli.com 14 Feb '03

I'm using zope to build some sites and building a UI that sits on top of zope for a non-ZMI user to edit content. (These are for all intent purposes static sites >> and the UI is for content editing / deleting / and occasionllay adding new content) Currently my architecture is setup like so: Folders used to represent the natural sitemap (i.e. about us, contact, products...) -- Within the folders are zpt pages -- or some other type of document where I'm storing the content. -- For example for the index.html for the about us page > that is a zpt > with all the content stored as properties of the zpt. I -- I've created propertes such as title / subtitle / body / bodycallout. Thus I use zpt for design and then use zpt w/ properties to store the content. (That's my two layers of content & design) Then for the UI, I expose those properites in form elements so they can be editied. (make sense?) So overall this is my architecture - but I'm looking for pros/cons of this setup? Any advice or insight?

I am a relatively new user of ZOPE and was wondering if it is possible to run programs on SAS from a ZOPE website ( or more specifically a plone website). Any help or a nudge in the right direction would be grateful.

Re: [Zope] Zope dies after a few seconds

Actually, the main problem was that I did not remove the old PID file that I backed up. AFter removing Z2.pid and pcgi.pid I was able to start Zope again. Gerhard Venter wrote: >Thanks.

Hi list, does anybody know, if there is a possibility in dtml, to let a dtml-var replace spaces to non breaking spaces ( )? like <dtml-var ... newline_to_br> Thanks in advance, Ulla.
