[Zope-CMF] Administering CMF discussions

[Pieter Claerhout]

Hi Tres,

I just upgraded to CMF 1.2 beta 2, and I'm trying this again, but without
luck.

I'm just wondering if I did it right or not. Here's what I did:

1. I created the script, and changed "talkback =
context.portal_discussion.getDiscussionFor()" to "talkback =
context.portal_discussion.getDiscussionFor(context)", because otherwise it's
saying that it is missing an argument.

2. In the list of replies, I add a link to each discussion item, which looks
like:
   http://myserver/site/test.html/talkback/1011210891/discussionitem_delete

If I try this out, it gives me the following traceback:

<!--

Any ideas why I did wrong?

Pieter

You will need to add a skin method, e.g., 'discitem_delete', which

operates on the 'talkback' object of the discussed content, e.g.::

   ## Script (Python) "discitem_delete"
   ## parameters=
   ## title=Delete discussion item
   parent = context.inReplyTo()
   talkback = context.portal_discussion.getDiscussionFor()
   talkback.deleteReply( context.getId() )

   context.REQUEST['RESPONSE'].redirect( parent.absolute_url()
             + '?portal_status_message=Reply+deleted' )


Then create an action for DiscussionItem (like the one you made
for edit) which has 'discitem_delete' as its action.  The
permission which governs 'deleteReply' is 'Manage portal', so
you won't be able to let others besides managers use the action
unless you write it as an ExternalMethod, or give it proxy roles.
