How to uninstall a product such as PTK or KnowledgeKit
by Meeting Maker Webmaster 12 Jul '00

Hello, I'm getting somewhat crazy with this one. I've upgraded my test server to 2.2.0b4 (from 2.2.0b3), i.e. transferred all the products I installed previously and the /var directory. Everything works fine with 2.2.0b4 until there. At that point, I realize that I have installed many products to "test" Zope, so I decide I want to uninstall all the products I won't use instead of exporting everything I did and re importing it on a clean server. So I delete all the products I don't need in the /lib/python/Products directory and go in the Control Panel/Products to delete all the products I just deleted physically from the hard drive. I restart Zope... everything still OK. The products are not listed anymore. So now I want to create a brand new product (ID: test). in test, I want to add a ZClass. In the available project, I also only see the products currently installed. But in the Add ZClass form, Zope offers me to use "DemoPortal: ..." or "KnowledgeKit: ..." as base classes. The only thing I really don't understand is that I just deleted these objects and they don't appear in the Products list anymore! OK, so they are still in the cache... let's use this "Flush cache" function in the database management... no effect. OK, so let's pack the database... to be certain, let's pack it to 0 days, as the problem with it has been corrected in 2.2.0b4 ;-)... no effect! So here is my question: How to really delete a product? I want to be certain I don't have any references to it left of previously installed products. I know I installed these products through the "import" feature and not by copying it into the /lib/python/Products/ directory, but that shouldn't make any difference? Thank you very much for your help.

.dtml files
by Daniel Rusch 12 Jul '00

12 Jul '00

I've been digging into to the inner workings of Zope trying to gleen as much Zen as possible, before I implement a write of our existing framework. During this process I have noticed that Zope's dtml pages are stored on the file system as .dtml files (i.e. roleEdit.dtml) The question then is how does Zope display this pages?? I have found function calls such as: manage_roleForm=HTMLFile('roleEdit', globals()) which I believe creates an HTML document template from the named file. But, what is the mechanism that calls/displays mange_roleForm? Thanks in advance, DR

SQL returning zero rows hangs ... but not with Gadfly !
by Nigel Head 12 Jul '00

12 Jul '00

(CVS version 11/July, Linux, Postgres 7) In summary, I have tried this with both the PoPy and ZPyGres flavours of PostGres adapter and with GadFly; these are the only d'bases I have available easily. Any SELECT query which returns no rows (a where <something impossible...> condition) seems to cause Zope to fail to respond to my browser. If I persevere a few times (maybe 7? haven't really counted) then Zope vanishes alltogether. BUT -- this doesn't happen with GadFly; there I duly get a report that no data was returned. I'll swear I didn't use to have this problem a coupel of weeks back, so I'm basivally suspecting Zope, but .... I'm in search of data points with other databases/zopes etc to find out whether this is postgres or what! I'm going to go get 2.2beta4 now and see what that brings ... Thanks in advance ... -- Nigel Head Houbits Hi-Tech Servers nhead(a)houbits.com

Check IE's security settings for the zone you are downloading the PDF from. The following is taken from Adobe's support site: -- If you're using Internet Explorer 5.0, make sure that its security options recognize the Acrobat Control: Note: This procedure changes Internet Explorer's security options for all ActiveX Controls. If you prefer to use stricter security, do not complete these steps. 1. Exit from Internet Explorer 5.0 and your Acrobat viewer. 2. Start Internet Explorer 5.0. 3. Choose Tools > Internet Options and click the Security tab. 4. Choose the appropriate Web content zone for the type of PDF file you're trying to open (e.g. Internet or Local Intranet). 5. Click Custom Level to specify the security setting for this zone. 6. Select Enable for the options labeled "Download unsigned ActiveX controls" and "Initialize and script ActiveX Controls not marked as safe." 7. Click OK and then click OK again. -=Brad=- -----Original Message----- From: R.

No, I hadn't heard about problems viewing PDF files from IE. Anyone else seen this? I suppose we should know what version of Zope you are running. --RDM _______________________________________________ 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 )

If I view the file, it opens Adobe Reader--but the page is If the folder appears empty, how do you view the file? When viewing the file, the fact that it opens Adobe Reader indicates that Zope returned some data and indicated the correct mime-type for a PDF file. That makes it sound like the data did indeed get uploaded, otherwise Zope wouldn't have been able to figure out its type (I think). > blank. If I go to the file on the network--it is fine.

I changed the file from > Publisher to PDF using Acrobat--should I have used some other method? Moving it to different locations on the network shouldn't make any difference. And once you upload it to Zope, the data being sent to the client browser is coming from data stored inside Zope, so at that point the network location of the file would be irrelevant. Did you try viewing the converted file before you uploaded it? Perhaps the conversion process produced a blank document? Otherwise... it sounds like Zope is returning something, but the data is invalid in some way. Perhaps if you tried doing a 'save' instead of viewing the link to the file, and you look at the contents of what gets downloaded, it might give you a clue. If you had a way to capture the data stream returned by accessing the file for viewing that would be better (say by telnetting to the web service port and typing in the get command by hand). --RDM
