[ANN] PropertyTools 2.0 released
by Maik Jablonski 23 Mar '04

23 Mar '04

Hi, yesterday I've released PropertyTools - the successor of PropertyObject/-folder. What the hell are PropertyTools good for? If you want to "prototype" object-oriented database-applications with Zope, PropertyTools will provide you with handy data-storages. If you get the idea behind PropertyTools (and the object-factory-tool AbracadabraObject), you can create simple database-applications based on the ZMI within 5 minutes (of course you can create complex applications with PropertyTools too, I've done some complex apps like univerisity-course-management-systems with lots of relations etc. based on PropertyTools in the last months which run nicely in production). If you spend just some additional minutes, you'll be done with a customized webapplication within 2 hours...:) Think of PropertyTools-Objects as lockable & sortable & workflowable ZMI-propertysheets which can be synchronized via a virtual class-attribute (object_type). Additionaly you can define different templates for rendering each virtual PropertyTools-class. Creating a simple faq-database or a contact-database with PropertyTools can be done in minutes, not hours... I'll promise! What's changed to 1.x? - Added PropertyFile besides PropertyObject & PropertyFolder - Added simple demo.zexp (a faq-database) to demonstrate how to use PropertyTools. - Updated property-sheets to Zope2.7-templates. - Refactored all code for managing the propertysheets into a new Mixin-Class PropertyTools. - Added additional Top/Buttom-Buttons for ordering properties. Thanks to Steve McMahon for his patches! - Fixed a bug in manage_changeProperties. Keyword-Arguments were broken for empty REQUESTs. Thanks to Abel Deuring! - Removed support for published-attribute. Added support for simple workflows based on PythonScripts. - Removed PropertyObjectDescription. Where can I download PropertyTools? http://mjablonski.zope.de/PropertyTools (and you should also download) http://mjablonski.zope.de/AbracadabraObject Keep zoped, Cheers, Maik

Say I have a page template a In that page I have a section like this: <div id="body"> stuff in the body </div> is there a way from page template b to render only the "body" div from a? <div id="insertedbody" tal:replace="here/templatefolder/a> stuff </div> -- David Bear phone: 480-965-8257 fax: 480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, everyone will be suspect of trespassing"

Opera 7 and ZMI
by Ron Bickers 23 Mar '04

23 Mar '04

Is anyone else using Opera 7 with Zope? Have you noticed this dangerous bug? http://my.opera.com/forums/showthread.php?threadid=23618 I reported it a year ago on the O7 beta list and they seem to not care enough to fix it. I know it's an Opera bug, but what change, if any, could be made to Zope to rid it of the wrap="off" that triggers this bug without losing the functionality it provides? -- Ron Bickers Logic Etc, Inc.

This modifies the > configuration and Zope.app() will do the right thing (tm). Neat, huh? Nope, I'm already using testrunner.py, so I'm already using the DemoStorage in its custom_zodb.py. If a transaction is committed, then changes still persist. > You may also be interested in the ZopeTestCase package which takes care > of all these things for you: <http://zope.org/Members/shh/ZopeTestCase> Thanks, I'll look into it. I'm already using your DEATH_TO_INSTANCE_HOME patch modified for 2.6.x, so that'd be nicer anyway. -- Karl Anderson kra(a)monkey.org http://monkey.org/~kra/

I really screwed up.
by Joe Goldthwaite 22 Mar '04

22 Mar '04

Hi all, I made the mistake of trying to upgrade a working system from Zope 2.6.2 to 2.7.0 one week before I demo to the company officers. I also decided that rather than have multiple copies of python all over the place, I'd just have one and I'd point my development tools over to it. I screwed up Visual Python so bad, it no longer runs any python code. I got around that by installing Komodo so I can now at least debug my program. Here's my problem. I'm using external methods extensively. My Zope instance is c:\website. My external modules are in c:\website\extensions. I've got two modules; Externals.py and BarsDB.py. Externals.py imports BarsDB. This was all working on Zope 2.6.2. Now I get an error message "AttributeError: 'module' object has no attribute 'BSConnection'" It's strange. It looks like its finding the module but not actually getting any of the names. It's also not generating any errors on the import command. (I was having that problem before with 2.6 but I got it working.) I wrote this little function to test import BarsDB def index_html(REQUEST): return "\n".join(dir(BarsDB)) When I run this from my development environment (Komodo at the moment), everything shows up. I get this list; AcctDesc BSConnection DataLine DataLines ... etc, etc. When I run the same routine from Zope, I get; __builtins__ __doc__ __file__ __name__ That's it. I thought that maybe Zope wasn't finding my BarsDB module and was generating a default empty module instead of generating an error telling me it couldn't find the module. I added a line c:\website\extensions to the Zope sys.path variable and it shows up correctly when I look at the debug information. Anyone have any ideas what could cause this? It seemingly finds my module but doesn't process it.

Can anyone suggest how I can include some debugging in a Python script? I don't suppose there is any way to single-step through a program is there? -- John

home option ignored on this platform
by John Poltorak 22 Mar '04

22 Mar '04

It seems that my problem with '--prefix' results from Python ignoring the home option. According to the Makefile, 'make install' runs:- running build_scripts /usr/bin/python "U:/unixos2/workdir/Zope-2.7.0/setup.py" install \ --home="/usr/local/zope" --build-base="U:/unixos2/workdir/Zope-2.7.0/build-base/python-2.3" --build-lib="U:/unixos2/workdir/Zope-2.7.0/build-base/python-2.3/build-lib" --build-scripts="U:/unixos2/workdir/Zope-2.7.0/build-base/python-2.3/build-scripts" --build-temp="U:/unixos2/workdir/Zope-2.7.0/build-base/python-2.3/build-temp" running install warning: ZopeInstall: home option ignored on this platform Where do I find ZopeInstall and why does Python decide to ignore the home option? -- John

pDocumentTemplate not compatible with cDocumentTemplate in Zope 2.6.4
by Johan Carlsson 22 Mar '04

22 Mar '04

I'm trying to look what happens in pDocumentTemplate by temporarily removing cDocumentTemplate, but when I remove cDocumentTemplate I get a "TypeError: object of type 'list' is not callable" in Module DocumentTemplate.pDocumentTemplate, line 210, in render_blocks when trying to access a simple DTML Method (or http://localhost/manage) It seems like the pDocumentTemplate is broken? -- Johan Carlsson Tel: + 46 8 31 24 94 Colliberty Mob: + 46 70 558 25 24 Torsgatan 72 Email: johanc(a)easypublisher.com SE-113 37 STOCKHOLM Skype: colliberty
