Jason, I reported this issue to the Collector (the Zope bug tracking system) and I hope to get a chance to take a closer look at it tomorrow. Sorry I can't be more helpful right now... - C ----- Original Message ----- From: "Jason Joy" <kyroraz@usa.net> To: "Chris McDonough" <chrism@digicool.com> Sent: Tuesday, April 10, 2001 8:24 PM Subject: Re: [Re: [Re: [Zope] Problem with passing objects from External Methods]] Yes, there is visible (non-only source) tracebacks available: Zope Error Zope has encountered an error while publishing this resource.

Chris,

I thank you for all your help with this frustrating issue. All your

changes

have pointed me in the right direction, but I am facing one other issue with it that I was wondering if you could shed some light on.

The <dtml-var foo> within the <dtml-in passthis(bar)> is raising an interesting error of:

Error Type: TypeError Error Value: call of non-function (type string)

Removing the <dtml-var foo> does not bring up this error, of course. Is there something that I am missing?

Chris McDonough <chrism@digicool.com> wrote: Hi Jason,

This is a stumper. But there's a solution. Rewrite your external method to look like this:

import string, regex from AccessControl import ClassSecurityInfo from Acquisition import Implicit import Globals

class element(Implicit): security = ClassSecurityInfo() security.declareObjectPublic() security.setDefaultAccess('allow')

def passthis(passed): info = [] structures = string.split(passed) for structure in structures: bit = element() bit.data = foo bit.source = structure info.append(bit) return(info)

Globals.InitializeClass(element)

For more info on why this is necessary, see

http://dev.zope.org/Wikis/DevSite/Projects/DeclarativeSecurity/ZopeSecurityF orDevelopers

HTH,

- C

...

def passthis(passed): class element: pass info = [] structures = string.split(passed) for structure in structures: bit = element() ## Get Information here, and store it in foo. bit.data = foo bit.source = structure info.append(bit) return(info)

This one has been driving me a bit crazy and I think there is a simple solution to this. I have written an external method to return a list of objects back to a DTML method which executes the code via a dtml-in.

The dtml code looks like:

<dtml-in processMethod(passthis)> <dtml-var sequence-index><dtml-var data><BR> </dtml-in>

And this is passthis.py:

import string, regex

def passthis(passed): class element: pass info = [] structures = string.split(passed) for structure in structures: bit = element() ## Get Information here, and store it in foo. bit.data = foo bit.source = structure info.append(bit) return(info)

When I run the code, I get a box that asks me to revalidate my Zope

login

and

...

nothing works, finally, the system gives up and gives me an error with this at the bottom:

File /usr/local/Zope-2.3.0/lib/python/AccessControl/ZopeSecurityPolicy.py, line 168, in validate Unauthorized: data

Does anyone have any advice on this one? This is an example of what I am doing and I need to pass a list of objects (with about 10 properties on each) to be run through a dtml-in.

Thanks,

Jason
