The actual indexes are defined elsewhere. So to upgrade catalogs you should do:<br><br>cat = getUtility(ICatalog, 'my_catalog')<br>cat['new_attribute'] = grok.index.Field.index_class('new_attribute')<br>cat.updateIndexes()<br><br>Regards,<br><br>Danilo G.

Following the example at
Grok<br>Documentation[1], let's say i've:<br><br>class SiteCatalog(grok.Indexes):<br> grok.site(Testvalueindex)<br> grok.context(MyObject)<br> grok.name('my_catalog')<br><br> counter = Value()<br><br>An my new catalog has a new attribute, called new_attribute:<br><br>class SiteCatalog(grok.Indexes):<br> grok.site(Testvalueindex)<br> grok.context(MyObject)<br> grok.name('my_catalog')<br><br> counter = Value()<br> new_attribute = grok.index.Field()<br><br>So, the problem is i've to re create SiteCatalog for my application<br>and "Source code for grok.index"[2] says "Note that, since index<br>creation (and thus a call to our :meth:`setup()` method) currently<br>occurs only during the creation of a new Grok `Application` object in<br>the Zope Database".<br><br>I tried to instantiate the index and they monkey patch, which it<br>wouldn't
be the most elegant solution but it could solve the problem<br>runing an upgrade method just once and i got an "can only be<br>instantiated on class level" exception.<br><br>So... any suggestion is very appreciated.<br><br>Kind Regards<br>Roberto Allende<br><br>1. <a href="http://grok.zope.org/documentation/how-to/implementing-search/view" target="_blank">http://grok.zope.org/documentation/how-to/implementing-search/view</a><br>2. <a href="http://grok.zope.org/doc/dev/_modules/grok/index.html" target="_blank">http://grok.zope.org/doc/dev/_modules/grok/index.html</a><br><br><br>------------------------------<br><br>_______________________________________________<br>Grok-dev mailing list<br><a ymailto="mailto:Grok-dev@zope.org" href="/mc/compose?to=Grok-dev@zope.org">Grok-dev@zope.org</a><br><a href="https://mail.zope.org/mailman/listinfo/grok-dev" target="_blank">https://mail.zope.org/mailman/listinfo/grok-dev</a><br><br><br>End of Grok-dev Digest, Vol
