shows nicely how to add a ZCatalog in a ContainerClass. How does one implement the same functionality when deriving a class A from ZCatalog:
A(ZCatalog) -- B(CatalogAware)
Check out my How-To, http://www.zope.org/Members/tseaver/inherit_ZCatalog
cool, thanks a lot. PARENTS[1].id is what I was looking for :-) (I forgot the .id)
How to modify <dtml-with "Catalog"> <dtml-call "manage_addColumn('area',REQUEST,RESPONSE,URL1)"> ?
Just call the method (of the ZCatalog-derived class):
<dtml-call "manage_addColumn( 'area', REQUEST, RESPONSE, URL1 )">
ok, I'll try that...
<dtml-with _catalog> will not work.
Right, attributes/methods starting with "_" are invisible to DTML.
I like deriving from ZCatalog, so the users do not see the Catalog (otherwise one could delete it) and the ContainerClass (Books) is the catalog of its members (Book).
Any hints?
This is essentially what I am doing -- I just tried adding a DTMLMethod named "Catalog" to the ZCatalog-derived class, which just returns this() -- IT WORKS!
Could you explain that with code? I'm not exactly shure hoh you do that. With that you do not need <dtml-call "manage_editCataloger( PARENTS[1].id, REQUEST )"> anymore. Is that right? You should ad this very cool trick to your howto (this will be my number 1. Zope magic Trick for this week :-)) -- Tom
