[Zope] Please Help! - Changing instance owner with external script...

[Rob Foster]

Hi there,

I've been trying to get the external script below to work with little 
success (I found it on ZopeLabs):

def custom_changeOwnership(self, username, obj):
     acl_users = getattr(self, 'acl_users')
     #UserFolder source
     user = acl_users.getUser(username).__of__(acl_users)
     obj.changeOwnership(user)

--------------------------------------------------------------------------------------------------------

I've got a script that grabs a username value "name" from a form and 
creates an instance in an adjacent directory. Using your script, I'm 
trying to get the owner changed to the same value... with no luck. I 
keep getting messages like this:

--------------------------------------------------------------------------------------------------------

Error Type: AttributeError
Error Value: changeOwnership

AttributeError: (see above)

  --------------------------------------------------------------------------------------------------------

Here's the script:

context.REQUEST.set('id', request.form['name'])
my_context= context.members.manage_addProduct['MyProduct']
my_context.Member_add(my_context,context.REQUEST, NoRedir=1)

context.customChangeOwnership(request.form['name'], 
context.members.REQUEST['name'])

  --------------------------------------------------------------------------------------------------------


I think maybe part of the problem is that I don't know what "context" 
means exactly and how to use it. I'm guessing this error is caused 
because an object can't be found?

Any help would be greatly appreciated.

Thanks,
Rob
