The first thing I would suggest is to forget about trying to do this in DTML. Write a Script for it, so you can code your logic in Python. You might also want to take a look at the CMFNewsFeed from the collective project on SourceForge (http://sourceforge.net/projects/collective/). The code there runs as a ZEO client, but you could do much of the same thing in your product. Doug On Thursday 03 October 2002 9:24 am, Paul Smith wrote:
Dear all,
Apologies if this seems a dumb question, but I've developed Zope-blindness from looking at this for a while now, and would appreciate someone pointing me in the right direction...
I'm trying to create a simple product for adding News items to folders within the ZODB. I am wanting to create the folder if it does not exist, and the folder name is built from values passed through from the form preceeding the constructor. Once the folder is created, or if it already exists, a news item should be added within the folder. This is where I am hitting a wall - I can't seem to create a namespace which allows me to create an object within the folder... The following is working code which creates a folder if needed, and the news item, but the next step is to create a news item within the newly created / existing folder.
<dtml-call "REQUEST.set('folderdate', displayfrom_month + displayfrom_year)">
<dtml-if "_.hasattr(this(), folderdate )"> <p><dtml-var folderdate> exists.</p> <dtml-with "newseventitem.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-call "propertysheets.newsevent.manage_editProperties(REQUEST)"> <dtml-call reindex_object> </dtml-with> <dtml-else> <dtml-call "manage_addFolder(id=folderdate,title=folderdate)"> <dtml-with "newseventitem.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-call "propertysheets.newsevent.manage_editProperties(REQUEST)"> <dtml-call reindex_object> </dtml-with> <p><dtml-var folderdate> doesn't exist.</p> <p>Item added</p> </dtml-if>
[newseventitem is the ZClass, and newsevent is the propertysheet associated with this ZClass]
If anyone can point me the right direction, or suggest a better way of doing this, I would be most grateful.
Cheers
Paul
