[Zope] Problems with External Script

[Thomas B. Passin]

If you want an external method to do something with the REQUEST, you have to
pass it as a parameter when you call that external method.  Otherwise the
method won't know anything about it.  Also, there is not an instrinsic
"self" parameter in a python function call.

All you need to do is something like this in the Zope page that calls the
external method:

<dtml-var "the_external_method(REQUEST)">

And in the external method:

def the_external_method(request):
    # Code to work with the request goes here
    # For example:
    some_variable=request['the_variable_name']
    # ...
    return thedata # Assuming that you have some data to return

No muss, no fuss, no selfs.

Cheers,

Tom P

When you use external scripts you don't use context. Just use self as you

It throws the same error, but with 'self':

Site Error
An error was encountered while publishing this resource.
Error Type: NameError
Error Value: global name 'self' is not defined

Troubleshooting Suggestions
·       This resource may be trying to reference a nonexistent object or
variable global name 'self' is not defined.
·       The URL may be incorrect.
·       The parameters passed to this resource may be incorrect.
·       A resource that this resource relies on may be encountering an
error.
For more detailed information about the error, please refer to the HTML
source for this page.
If the error persists please contact the site maintainer. Thank you for
your patience.

Again, here's the script:

import string

def myaffiliateprogram():
  user_id, banner_id, page =
self.REQUEST['user_id'],self.REQUEST['banner_id'],self.REQUEST['page']
  redirect =
"http://www.myaffiliateprogram.com/u/%(user_id)s/t.asp?id=%(banner_id)s&p=%(
page)s"
% locals()
  print "Location: %(redirect)s\n" % locals()

The idea of the script is to have someone hit the page (which has only this
External Method) and be redirected. Obviously, I'm missing something
fundamental here. Ideas?
TIA,
BenO
