First of all, thanks to everyone for their help. I've been trying to figure out how to do this one set of things for ages now. I've sent countless emails to the newsgroup and I still run into problems. Here's my problem, perhaps you can help once more... I'm creating a site where people will come and signup to become members. This is what happens (or should happen): 1. The user fills out a form that has fields to choose their username and password along with a confirmation field. This form posts the python script below which is called "addUser" (I left out the top half of this script which adds a user to the acl_users folder) ------------------------------------------------------------------------------------------ request = container.REQUEST RESPONSE = request.RESPONSE request = context.REQUEST request.set('id', request.form['username']) tmpObj = context.membersfolder.manage_addProduct['MyProduct'] tmpObj.MyZclass_add(tmpObj, request, NoRedir=1) ------------------------------------------------------------------------------------------ As you can see, this script adds an instance of my zclass (MyZclass) in an adjacent folder called "membersfolder" with owner set to my admin account. This works fine, until I add the two lines below which should change the owner: ------------------------------------------------------------------------------------------ #THE FOLLOWING LINE IS LINE 27 - SEE THE TRACEBACK BELOW obj = _.getitem(request.form['username']) context.custom_changeOwnership(request.form['username'], obj) ------------------------------------------------------------------------------------------ The two lines above are supposed to work with the external script below: ------------------------------------------------------------------------------------------ def custom_changeOwnership(self, username, obj): """ explicitly setup changeOwnership for TTW """ acl_users = getattr(self, 'acl_users') #UserFolder source user = acl_users.getUser(username).__of__(acl_users) obj.changeOwnership(user) ------------------------------------------------------------------------------------------ When I add those two lines, I keep getting the following error where "foo" is the username I'm typing in the form: ------------------------------------------------------------------------------------------ Error Type: KeyError Error Value: foo Traceback (innermost last): File /Users/rfoster/Desktop/Zope-2.4.1-MOSX/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /Users/rfoster/Desktop/Zope-2.4.1-MOSX/lib/python/ZPublisher/Publish.py, line 187, in publish File /Users/rfoster/Desktop/Zope-2.4.1-MOSX/lib/python/Zope/__init__.py, line 226, in zpublisher_exception_hook (Object: LockableItem) File /Users/rfoster/Desktop/Zope-2.4.1-MOSX/lib/python/ZPublisher/Publish.py, line 171, in publish File /Users/rfoster/Desktop/Zope-2.4.1-MOSX/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: addUser) File /Users/rfoster/Desktop/Zope-2.4.1-MOSX/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: addUser) File /Users/rfoster/Desktop/Zope-2.4.1-MOSX/lib/python/Shared/DC/Scripts/Bindings. py, line 324, in __call__ (Object: addUser) File /Users/rfoster/Desktop/Zope-2.4.1-MOSX/lib/python/Shared/DC/Scripts/Bindings. py, line 354, in _bindAndExec (Object: addUser) File /Users/rfoster/Desktop/Zope-2.4.1-MOSX/lib/python/Products/PythonScripts/PythonScript. py, line 363, in _exec (Object: addUser) (Info: ({'script': <PythonScript instance at fdaf60>, 'context': <Folder instance at ffeaf0>, 'container': <Folder instance at ffeaf0>, '_': <TemplateDict object at 0xcbfa20>, 'traverse_subpath': []}, (), {}, None)) File Script (Python), line 27, in addUser (Object: guarded_getitem) KeyError: (see above) ------------------------------------------------------------------------------------------ I should also note that the binding in my script is set to: "_" Any help would be appreciated. I must really suck. I've been working on this same darn problem for almost three weeks now... ugh. I should also mention that I'm pretty green... All this code was written by others and I'm just trying to get it all to work right (I'm no programmer) Thanks in advance, Rob
