You could probably use ZCatalog in conjunction with LocalFS to accomplish this; I think LocalFS was recently revved to allow cataloguing. Note that the actual mass-indexing process is going to be *painful*, as ZCatalog is intended to ease incremental indexing. I think I would write a script which walked the hierarchy, calling a method to index one (or a few) messages at a time. This script might also need to pack the database at intervals; the catalog is a bit space inefficient across mutliple index/reindex operations.

It is included in the zope-distribution or can be found at http://www.zope.org/Members/itamar/load_site It doesn't do XMLDocuments, but I found it a great help in figuring out how to inject a bunch of external files into zope. I guess you just have to change the relevant lines to create XMLDocuments instead of DTML-ones. cheers, oliver

Help - cannot import zexp
by Oleg Broytmann 02 Dec '00

02 Dec '00

Hello! Please help, I have a problem importing my zexp. Initially I created the exported zexp while debugging some External Method. The method is declared as follows: def navigation_leftColumn(self, _, render=default_render): ... where default_render is a helper function, defined in the same .py file: def default_render(self, _, alist=None, indent=0): ... Later I deleted the entire folder and tried to import zexp to return to saved position. Zope raise the error: "Cannot import default_render from module __main__". Oops! What's that? The default_render isn't in __main__, sure. I tried to create External Method before importing, but this didn't help :( Oleg. ---- Oleg Broytmann http://www.zope.org/Members/phd/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.

Passing lists in a get request (ZCatalog Search)
by Darin Lee 02 Dec '00

02 Dec '00

Zopistas, I have a catalog aware ZClass publication object that I want to have searchable. There are 3 criteria I want users to be able to select in addition to a search string textbox. I created field indexes for the criteria in the zCatalog, and made a form where users can select the indexes with checkboxes to limit their search. The selected items are then passed to my search method - which in turn executes a <dtml-in> to produce the result set. The whole thing works great, until I decided to try to add column sorting functionality (Like the zope downloads page). Here is the problem, I run the query and the page comes up correctly on the first iteration, but when I try to sort the column (with a ?sort_on=index "get" request), the selected criteria are forgotten and the entire result set is returned sorted. for example, one of my search criteria is "theme" - there are four possible (Air, Land, Water, and Waste). the request would look like: search?meta_type=Publication&theme=Air&theme=Land&theme=Water I can't figure out how to pass a list in the get request. How do I pass more than one theme to the method as a list? I have discovered through trial and error that I can pass it the values if I repeat theme for each list item. However, I also have a criteria - "category" with over 32 items, and a criteria - "division" with 14 items. This becomes extremely clumsy with "category=reports&category=guidebooks&division=lwm&division=aqd" etc. repeated 32 times. Not to mention that there is a limit of how much info I can pass in the get request itself. Is there a better way to pass the lists to my method? Thanks in advance! -Darin Lee

Been pretty quiet on the lists WRT HiperDOM, which I got the impression was going to be about this. Are there any DC initiatives into this? Lalo, any word from the trenches? ;-) cheers, Chris

weird bug?
by michael angelo ruberto 01 Dec '00

01 Dec '00

hi, one of the DTML methods i've created recently has started to create problems. the method adds properties to documents as people browse zope. it worked fine for a while but now it's causing zope to prompt for a password. i gave the method manager proxy which solved the problem on my test server but didn't make a difference on the intranet zope. the error generated when you click Cancel on the password prompt is "You are not authorized to access manage_addProperties." as far as i know nobody has changed anything related to permissions. is there some kind of bug causing this? the method is being run on version 1.5.2. any ideas appreciated. -<mike>-

Help! Accessing product constructors & methods programmatically

Hello, Zopers-- I'm fairly new at this, so I apologize if this is a dumb question. Anyway, I've been looking for a way to do a bulk upload of XML documents from a local directory. So I need a method (either DTML or Python is fine with me) that would build a list of files and create an XML Document object from each one. I have tried a variety of different approaches, but I can't find a way to access the XMLDocument.add() method. Can anyone suggest an approach to this problem? Any relevant documents I need to read? Thanks in advance for your help.

Making lots of external data searchable?
by Anselm Lingnau 01 Dec '00

01 Dec '00

I'm using Zope to re-vamp a web site, one of whose most important features is an archive of a reasonably busy mailing list, which is accessed using home-grown Perl CGI code. I've written Python code to let users browse the archive sorted by users, subject etc., but now I'm looking at allowing text searches. The »old« instance of the web site used Glimpse and a simple CGI script (in Perl) to do this across the whole site (including the mail archive) and ideally this would be what I'm after for the new version as well. However, the mail archive now weighs in at about 45 MB in individual text files (one per message), and I don't really see myself putting this into the ZODB so I can use ZCatalog. ZCatalog, however, looks good for indexing the rest of the site (I haven't done this yet). Is there a reasonable way of interfacing Glimpse with the Zope searching machinery so I could again have one-stop searching of the whole site? (It would probably be straightforward to search just the mail archive by calling out to Glimpse and massaging the results.)
