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
