Re: [Zope] Catalog question

Is it possible using an expression to disallow an object being added to a catalog based on a certain string being contained in its path? For example, I want to include all objects in a subfolder except if the path includes the name 'sample' in the path.

I think this may be possible utilizing the "expr" field on the Find Objects tab of a ZCatalog, but I'm not certain how to write the expression. Can anyone offer some advice? I solve problems of this kind with the following two step approach:

* determine the list of objects in any appropriate way. My favorite is "ZopeFind" (the method behind Zope's "find" tab). * Interate over the list and call "Catalog.catalog_object" for each object. Dieter
