RE: [Zope-dev] CatalogAware must come before ObjectManager

If > this is expected behavior, then this should probably be documented... This is the intended behavior. Both ObjectManager and CatalogAware define a manage_afterAdd method. The CatalogAware class must be subclassed first in order for it's afterAdd to be called instead of ObjectManagers. This is identical behavior to python. You're right, it should be documented. > > BTW, will it ever be possible to change the Base classes of a ZClass? > It is possible, but only from python, and it is a *real* hack. Doing this is completely unsupported. I might get shot for revealing the technique. Given a Product called 'YourProduct' that contains a Zclass called 'YourZClass' that you want to 'rebase', first, create a temporary ZClass called 'TempZClass' in the same product. 'TempZClass' should be built with the new order or types of subclasses that you want 'YourZClass' to have. Note that 'TempZClass' need not have anything in it, it just needs to subclass the right classes. Shut down Zope, run python1.5.2 in your lib/python directory, and execute the following code: >>> import Zope >>> p = Zope.app().Control_Panel.Products.YourProduct >>> p <Product instance at 849de28> >>> p.YourZClass._setBasesHoldOnToYourButts(p.TempZClass._zbases[1:]) >>> get_transaction().commit() -Michel > Kevin > > > _______________________________________________ > Zope-Dev maillist - Zope-Dev(a)zope.org > http://www.zope.org/mailman/listinfo/zope-dev > > (To receive general Zope announcements, see: > http://www.zope.org/mailman/listinfo/zope-announce > > For non-developer, user-level issues, > zope(a)zope.org, http://www.zope.org/mailman/listinfo/zope ) >

SQL METHODS - Obtaining ROW IDS in an <IN> STATEMENT
by Theodore Patrick 05 Aug '99

05 Aug '99

Here is the situation: I have a method called item_method. It contains SQL:SELECT that returns 10 rows of data. When I want to print this to a page in ZOPE. I use an <IN> Statement as follows. Currently the data set from the database does not return a row number, so I need Zope to make one up as it prints the HTML. The data set has two columns called this and that. I need the code that generates the  in the following code.  ROW_NUM=  THIS=, THAT=  As always - Thanks in Advance. Theodore E. Patrick http://www.ishophere.com Where do you shop?

how to call overridden method of super-zclass?
by Martijn Faassen 05 Aug '99

05 Aug '99

Hi there, Imagine I have two ZClasses, ZClass A and ZClass B. ZClass B derives from ZClass A. Now if ZClass A has a DTML Method 'foo' and I override this DTML Method inside ZClass B, how can I still access this method from within the overridden method? Basically I want to refine methods, keeping the functionality of the superclass but adding some new functionality of my own. Regards, Martijn

If so, can anyone recommend a site where there >is a demo or tutorial or any other good information relevant to this. If it >isn't suitable, can anyone recommend any other good tools (either opensource >or commercial). Zope is _outstanding_ for maintaining database content. I'm mid-way through building a quite large and complex database application (a customer database) which uses Zope as the frontend, and an SQL database or two as the backend. It's not something that I can show outside, unfortunately, but it makes heavy use of Zope's SQL interfacing abilities... Anthony (ob-zope-dev: oracle's SQL features a neat feature allowing you to automatically traverse parent/child object trees - this allows you to do some incredibly cool stuff. look for select... connect by... in the docs.)

Re: [Zope-dev] PyGreSQL DA: help testing
by Ross J. Reedstrom 05 Aug '99

Zopistas: I've been doing a little testing, and it looks like my TM integration isn't quite there yet :-( I threw an error in the backend by putting a typo in an ZSQL method (I did it on purpose... right ;-) This threw an error, all right, and the backend was in a transaction, but it never saw an abort. So, it looks like I need to dig into the TM machinery a bit more: my self._abort() isn't getting called when I throw an error inside the db.py itself. Any hints on what I need to be doing? (RTFS and a pointer to the right S would be fine ;-) Ross -- Ross J.
