[Zope] Catalog Awareness

[Robert Rottermann]

hi geoff,

add the following methods (they are from Zwiki)
and call self.reindex() each time you change something
the code assumes that a catalog called 'Catalog' can be aquired.

Robert

    def getCatalogId(self):
        """Return the name of the catalog used by this document"""
        return getattr(self, 'Catalog')

    def url(self):
        """Return the absolute object path"""
        return string.join(self.getPhysicalPath(),'/')

    def index_object(self):
        """A common method to allow Findables to index themselves."""
        if hasattr(self, self.getCatalogId()) and \
           not getattr(self, 'NOT_CATALOGED', 0):
            #sys.stderr.write( 'INDEXING PAGE!' +'\n') #SKWM
            getattr(self, self.getCatalogId()).catalog_object(self,
self.url())
            self.is_indexed_ = 1
            #sys.stderr.write( 'INDEX DONE!' +'\n') #SKWM

    def unindex_object(self):
        """A common method to allow Findables to unindex themselves."""
        #sys.stderr.write( 'UNINDEX_OBJECT!' +'\n') #SKWM
        if hasattr(self, self.getCatalogId()):
            getattr(self, self.getCatalogId()).uncatalog_object(self.url())
            self.is_indexed_ = 0

    def reindex_object(self):
        """Reindex the object in the Catalog"""
        if getattr(self, 'is_indexed_', 0): self.unindex_object()
        self.index_object()
