Re: [Zope-dev] skinscript and URL traversal question
Hi all, A solution has been found. woohoo. A not found error was produced with direct URL traversal. Steve Spicklemire sent this solution off list. The process is split into two steps: Do the query to 'load the object on traversal': WITH QUERY searchBy_Name(name=self.id) COMPUTE name Do the query to 'load the attributes needed for rendering a particular document': WITH QUERY searchByNameCheck(self.id) COMPUTE username,coupon_text,categorylist,categoryheader,expirationdate,status,couponterms During traversal AUTHENTICATED_USER is not yet defined, so it's no good trying to get to it. However, once authentication has happened (after Zope has sorted out what object you're after an imposed security on the object..) then it should be OK. Since the Storage tab uses 'name' to load the object, we can't access AUTHENTICATED_USER before loading 'name', but the other attributes are OK. -Aaron ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

[Zope-dev] skinscript and URL traversal question
Hi all, I originally posted this to the zope list and, upon suggestion, I am reposting it to zope-dev. I'm using a zsql method in a skinscript with query ... compute ... and it mostly works. Retrieving the dataskin with getItem() works. For example, Cid is the id of the coupon dataskin. Trying to access the object directly through URL traversal fails. http://CouponSite/CouponManager/977931214.694/CouponDetails Where: CouponManager is a specialist 977931214.694 is the id of the coupon dataskin CouponDetails displays the coupon attributes with: It returns a not found error. The CouponManager specialist can't find the coupon 977931214.694. Any thoughts why this is so?
