problem with querying a catalog
Hi, I have some trouble querying a catalog. This DTML works. It get's only the edf objects in the path. <dtml-in expr="dfcatalog(meta_type='edf', path='/avin/literatuur/antroposofische_literatuur/artikelendatabase/ms')"> <a href="&dtml-absolute_url;"><dtml-var title></a> </dtml-in> This Python script doesn't work. It returns ALL the edf objects on the site. zcat=container.dfcatalog results=zcat({'query' : '/avin/literatuur/antroposofische_literatuur/artikelendatabase/ms','meta_typ e':'edf'}) Thoughts? Henny
you do not indicate whath index to use for the path. Robert Henny van der Linde wrote:

Thoughts?

No it doesn't. I tried that before. Henny

Have you tried: zcat=container.dfcatalog results=zcat.searchResults({'path' : '/avin/literatuur/antroposofische_literatuur/artikelendatabase/ms','meta_typ e':'edf'}) This assumes that 'zcat' is a ZCatalog and that 'path' and 'meta_type' are indexes you have set up. Jonathan

with other words: zcat() and zcat.searchResults() are equivalent :-) zcat.search() has a different call signature :-) Regards Tino
Hi, To all who respondend. Thanks I made two stupid errors. First I didn't have a path index defined. Second the dtml worked the same as the python script, I will not get in the gritty details. ;) Henny

Why "path" in the dtml example but "query" in the python script example? Different arguments to the same method can produce different results :-) Regards Tino

The dtml is an example I picked from the net. The python script is in the Zope book while using records. However this: zcat=container.dfcatalog results=zcat({'path' : '/avin/literatuur/antroposofische_literatuur/artikelendatabase/ms','meta_typ e':'edf'}) won't work either. Henny .

Well. You still use different interfaces :-) Why not in the python script use _the same_ expression? After all, its the very same object and so the same interface like in the DTML example :-)) Python Script: results=container.dfcatalog(meta_type='edf',path='/avin/literatuur/antroposofische_literatuur/artikelendatabase/ms') See the identity? :) See also Zope Book API description. Or the source of ZCatalog: 625 def searchResults(self, REQUEST=None, used=None, **kw): 626 """Search the catalog 627 628 Search terms can be passed in the REQUEST or as keyword 629 arguments. 630 631 The used argument is now deprecated and ignored 632 """ 633 634 return self._catalog.searchResults(REQUEST, used, **kw) 635 636 __call__=searchResults 637 638 def search( 639 self, query_request, sort_index=None, reverse=0, limit=None,merge=1): 640 """Programmatic search interface, use for searching the catalog from 641 scripts. 642 643 query_request: Dictionary containing catalog query 644 sort_index: Name of sort index 645 reverse: Reverse sort order? 646 limit: Limit sorted result count (optimization hint) 647 merge: Return merged results (like searchResults) or raw 648 results for later merging. 649 """ Regards Tino
