Re: [Zope-dev] ZPatterns Project Help!
Hi Ben, GAPs are sort of deprecated at this point in favor of SkinScript. In SkinScript you might do something like this: WITH accounts.getItem(self.account_id) COMPUTE account_object=RESULT or more carefully... WITH accounts.getItem(self.account_id) COMPUTE account_object=(RESULT is _.None) and NOT_FOUND or RESULT -steve "bentzion" == bentzion [EMAIL PROTECTED] writes: bentzion Another question... bentzion I want to have a GAP that will add some other Object to bentzion an attribute of my DataSkin.

RE: [Zope-dev] ZPatterns Project Help!
Thanks for answering Steve.
Unfortunitly I am working with version 0.3 of ZPatterns so I have
to use GAP.
When I try to translate your Skinscript into GAP like this
"attrsexprs:account_object=(RESULT is _.None) and NOT_FOUND or
RESULT" and I try to access the object's id with dtml-var
"account_object.id" I get a "NameError" on account_object.
Alternativly if I do dtml-var account_object I get a "KeyError".
(BTW. for testing I used "accounts.getItem('1434')" which is a
valid object. If I do "account_object=RESULT.id" it works fine.)
I appreciate any help on this.

Perhaps this is a security issue? When you set account_object=RESULT.id,
then the account_object attribute is a string, and has no security
protection from access by DTML. When it is an object, however, your DTML
must have permissions to the object itself. I am not positive, but I think
ZPatterns 0.3 may have executed GAP expressions as the superuser, so it may
be that your GAP is able to access the object, but not the DTML which is
using the DataSkin.
