This seems to be the frustratingly lame behavior on linux, winnt, win 9x and solaris!!! If I recall correctly, this cache stuff has been broken througout 4.x I've not been able to find an acceptable workaround other than the one you mention above. Frustrating as hell, isn't it? --Rob

Theoretically, the same should work dandy with just addDTMLDocument, but it doesn't. I'll put that in the collector if it's a bug... You can change the objects content through 'manage_edit'. -Michel

It sound like you don't want to extend Zope by writing a product; you just want to publish your own Python objects on the web Bobo-style. I just wrote a small how-to which explains how to do this with a stock Zope installation: http://www.zope.org/Members/Amos/ZPublisher Let me know if this doesn't answer your question completely.

Michael, I assume you're running Zope on NT. Install the ZODBC database adapter (http://www.zope.org/Products/DA/ZODBCDA) and follow the directions which come with it...

RE: [Zope] Adding a document using a form
by Mats Myrberg 29 Nov '99

29 Nov '99

Hi, I am a complete Zope newbie so have some patience with me. Mike suggested a way to Lalo to move the code that creates the DTML Document into a DTML Method. I tried this method but I get the below error and stack trace. It seems that the call to self._setObject is failing. What is self in this case? BTW the add form is living in a folder called Products in the root folder. My code for the DTML Method is: <dtml-call "Products.manage_addProduct['OFSP'].addDTMLDocument(id, title)"> It does not seem to matter whether I prepend the Products object on the call string or not. Hopefully I will be able to contribute to the list as I come up to speed. -Mats Error Type: AttributeError Error Value: 'string' object has no attribute '_setObject' Traceback (innermost last): File C:\Program Files\ZopeSite1\lib\python\ZPublisher\Publish.py, line 214, in publish_module File C:\Program Files\ZopeSite1\lib\python\ZPublisher\Publish.py, line 179, in publish File C:\Program Files\ZopeSite1\lib\python\Zope\__init__.py, line 201, in zpublisher_exception_hook (Object: ElementWithAttributes) File C:\Program Files\ZopeSite1\lib\python\ZPublisher\Publish.py, line 165, in publish File C:\Program Files\ZopeSite1\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: secureAddMethod) File C:\Program Files\ZopeSite1\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: secureAddMethod) File C:\Program Files\ZopeSite1\lib\python\OFS\DTMLMethod.py, line 145, in __call__ (Object: secureAddMethod) File C:\Program Files\ZopeSite1\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: secureAddMethod) File C:\Program Files\ZopeSite1\lib\python\DocumentTemplate\DT_Util.py, line 321, in eval (Object: Products.manage_addProduct['OFSP'].addDTMLDocument(id, title)) File <string>, line 0, in ?

[Q] My own editor?
by Bernhard Reiter 29 Nov '99

29 Nov '99

Viva de el Zopistas, new to Zope, I have a few questions which I couldn't find the answer for. How can I export a DTML method file, so that I can add it again? Background: I want to use my own editor, as the webbrowser's text window usually is a real bad editor. (Of course I know, if the world would be more modular, I could just call my editor from the webbrowser. Most people are stuck with Mosaic-derived webbrowser (netscape/IE/Mozilla).) Another question: Would it not be advantagous only recreate a page, when the source objects change and trigger that creation? Most pages could just be cached this way. Or does Zope that already? Please cc: me answers, because I am not on the Zope list (just to huge). Regards, Bernhard -- Research Assistant, Geog Dept UM-Milwaukee, USA.

raise from external method and rollback trans [Q]
by Bruno Mattarollo 29 Nov '99

29 Nov '99

Hello, I am developing an External Method that checks for several parameters to be passed and does a lot of insert/updates in an Oracle database... I have several "checkpoints" and when one fails I want to be able to do a raise and rollback all the open (uncommited) transactions, since the DCOracle is a Level 3 adapter, there is no problem, because the transaction mechanism from Zope is integrated. But know here comes my question: how do I rollback a transaction without doing a raise? I need to do this to server diferent error pages when an error ocurrs... I mean, I have to present for example a form with all the fields the user filled in, or if there was another error, present another form. I do not want to use the standard_html_error ...

Connecting to Ms Access w/ Zope?
by Michael Maier 29 Nov '99

29 Nov '99

This is probably a very basic question: How do I connect to an MS Access DB using Zope? I have created the DSN in the Control Panel --> ODBC. The only place I see to make a DB connection is with the Gadfly thing -- is there something else I need to install? If so, what and how? - Michael Maier
