[Grok-dev] Create index catalog in Zope3 management interface

[Simon Jagoe]

Hi,


I have recently started using Grok 1.0 to develop an application. I am
now looking into indexing items in the ZODB, and one thing I was
trying to do is add and manipulate catalogs through the Zope3
management interface at http://localhost:8080/app/++etc++site/ .

I have created a new catalog through the interface, but when I try to
create index fields to this catalog, I get the traceback below
(ForbiddenAttribute on the keys() method of my grok.Application) in
the console. If I use the app.keys() method in my application,
everything seems to be OK (the zope.manager user does have access to
this attribute). Do I need to add some rules to the ZCML or is there
some other way to build indexes after the application has been
created?

This error occurs in a fresh application created using the grokproject
command. Can anybody provide me some pointers of where to look?

indexing.app.Indexing is the application class inheriting from
grok.Application and grok.Container.
