[Zope] Help! Trying to create an instance and then change the owner...

13 Nov 2001

      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 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
