Re: [Zope-dev] problem adding ZClass instances via DTML

[Gilles Lenfant]

Mark,

It seems you forget the id of your new object !!
I use do do it in Python script (easier for testing initial data from request). But 
you can translate in DTML if you prefer...
# Test initial data from REQUEST and redirect somewhere if required
...
# Create the new ZClass based object
newobject = 
somefolderishobject.manage_addProduct['MyProduct'].MyZClass.createInObjectManager(newId,
 context.REQUEST)
# May add computed values to properties
props = {}
props['created'] = DateTime()
props['creator'] = context.REQUEST.AUTHENTICATED_USER.getUserName()
...
newobject.propertysheets.mypropertysheet.manage_changeProperties(props)
# Redirect somewhere or return the object or whatever

HTH

: Any suggestions?

Where is the second positional argument for DTML objects?

Please read "Calling DTML objects" in

  

to avoid such errors in the future.
