External Methods triggers Zope restart

I am having a frustrating problem with External Methods. I have regressed to Zope 2.4.0 to try to resolve this. Basically, the following external method works: def helloWorld(): """A simple external method.""" return 'Hello World!' But the following method causes Zope to restart with no traceback: def helloWorld(): """A simple external method.""" a = 'Hello World!' return a If I use self.a instead of just a, the method works. I used th epython debugger, and the correct HTML is displayed in both cases. I don't find anything usefull in the -M log either. Has anyone seen anything like this, or have any ideas where I should look next. Thanks, Paul OS: HP-UX 10.20 Python 2.1.1 Zope 2.4.0

RE: [Zope] Rendering Word .doc and PowerPoint .ppt as thumbnails

Could you use something like http://www.zope.org/Members/eric/MSWordDocument or http://www.zope.org/Members/sf/NuxDocument, grab a few lines of the HTML, and display those lines in a small box using a small font size? You could possibly adapt the MSWordDocument to export powerpoint if you are on windows via com. -Scott -----Original Message----- From: Brian Sullivan [mailto:brians@meetingbywire.com] Sent: Friday, November 09, 2001 2:37 PM To: zope(a)zope.org Subject: [Zope] Rendering Word .doc and PowerPoint .ppt as thumbnails Anybody have any idea how this can be done as a server function( either statically in conjunction with upload of the files or dynamically as server callable function) _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Redirecting a browser if len(someSQLQueryResult) == 1
by Timothy Wilson 09 Nov '01

09 Nov '01

Hi everyone, I'm building a SQL-based app for my site that makes it posssible to enter a street address and city into a form and search for which elementary, middle, and high school children at that address would attend. I've got all the SQL stuff working well. Now I'm working on trying to improve the interface. Here's what I want to do: If someone performs a query using a street address like '123 Maple', the query returns a list of matching items that might include '123 Maple Ave', '123 Maple St', etc. This is what it's supposed to do. The user then sees a list of potential matches with each item a hyperlink to the specific school information for that address. For example: /info/dwelling_info/dwellingID/971335/attendanceAreaRpt calls the attendanceAreaRpt on the results of a 'dwelling_info' ZSQL method using dwellingID = 971335. No problem there. If the original search only returns one result, I'd like the browser to go directly to the info for that address without having to take the additional step of clicking on the address in the search report. I can do <dtml-call "RESPONSE.redirect('/info/dwelling_info/dwellingID/971335/attendanceAreaRpt')">, but the obvious problem is that I've hardcoded the dwellingID. How can I dynamically insert a portion of my SQL query (the dwellingID) into my redirect? -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.org | http://www.zope.com W.

Random code?
by Jonathan (Listserv Account) 09 Nov '01

09 Nov '01

Hi list, Trying to randomly insert content into a page, using the following code: <dtml-var expr="_.whrandom.choice(myFolder.objectValues())"> which chooses a random object from the folder 'myFolder' and includes it in the page. When I include HTML however, all '<' and '>' are rendered as '<' and '>' respectively, making the HTML code show up on the page. Anybody knows how to make it just include the code without changes? Thnx, Jonathan

GadFly DB and caching
by Oliver Erlewein 09 Nov '01

09 Nov '01

Hi I've got a small GadFlyDB running on Zope. Since it was quite slow I changed the "Maximum time (sec) to cache"-value to 300. This improves the speed quite dramatically! :) The problem is, that chages and deletes of tablerows don't show immediately. How do I do a cacheupdate?

external methods returning objects
by Stephan Herschel 09 Nov '01

09 Nov '01

Hi, I've just tried to return a python-object from an external method and to use this from inside zope. I tried to call a method of this object, and funnily no error appeared but i was prompted for authentication again. Does this make sense? Is there a workaround? thanks, stephan

Photo clashing with ZSQL method
by Timothy Wilson 09 Nov '01

09 Nov '01

Hi everyone, Here's an odd error: I'm working with the ZPsycopgDA, a PosgreSQL database and a couple ZSQL methods. When I click on the "Advanced" tab inside my ZSQL methods I get the following: Error Type: SystemError Error Value: Failed to import class _ZClass_for_ZPhotoAlbum from module Products.Photo With the traceback:  Odd. Anyone have any thoughts on this? -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.org | http://www.zope.com W.

Id of root object?
by Terry Hancock 09 Nov '01

09 Nov '01

Hi, I'm (obviously?) a new Zope user. I've been working on a website -- originally it was organized as: http;//my_url:8080/AnansiWWW where "AnansiWWW" was a folder, and everything else was below that. However, for various reasons, it's clear that we want the public version of the site to have the stuff in AnansiWWW appear at the root level, i.e: http;//my_url:8080/ So I've been trying to move stuff up. However, I've been using a navigation bar that uses a bit of code like this to determine where "Up" should be for each folder: <dtml-var expr="_.getitem(Up).absolute_url()"> This is nice, because I can set "Up" to be a property of the folder and exercise a bit more creative control over the navigation bar's behavior. It worked fine before, where going to the home page could be acheived by simply setting Up to "AnansiWWW". I tried some alternatives before coming up with the "getitem" approach above, but I couldn't figure out anything simpler that would do what I needed. But here's the problem -- now I want that to resolve to simply: "/" in the event that Up is simply the home page. I can't reasonably use "index_html", because that might resolve to some intermediate folder that was not intended ("index_html" being used in a lot of places). For this to work, I need an ID for the root folder. I've not been able to find any reference to this in the documentation I have, and obvious guesses like "" "root" "/" "_" "." ".." "Root Folder" "BASE0" etc, don't work. I even tried leaving out the "Up" property and using a "missing" line in the DTML, but that doesn't work either (apparently it still tries to evaluate the getitem() and generates an error. If it's really not possible to refer to the root object, then how else could I code this to acheive my purpose? Thanks!
