[Zope] Acqusition and External Methods...

[Tony McDonald]

Ok,
I 'simplified'? my code of a few hours ago and got this

External Method: testDocTemplate.py

import DocumentTemplate
from Acquisition import Implicit

def doit(self):
         template_str = '''<table>
<tr><td bgcolor=silver colspan=2>This data is being dynamically 
generated from a database</td></tr>
<dtml-in "info_from_email(email=content)">
<tr><td><dtml-var Title> <dtml-var Surname></td></tr>
</dtml-in>
</table>'''
         template = DocumentTemplate.HTML(template_str)
         return template(content='hirst')

(1) info_from_email is a ZSQL method *in the same folder* as the 
external method itself.
(2) Ideally I want to get a DTML document in the folder heirarchy, ie 
template_str = str(self.Actors.RENDER.modulecontributor)

On clicking 'Try It' I get:

<!--
  Error type:  NameError
  Error value: info_from_email
  -->
