sorry about this red herring - the problem was that i had
inadvertently chose 'redirect_to' instead of 'traverse_to' in my
controller page template, which of course, zapped the options. 20
hours of programming time wasted!

i solved it like this:
python:request.set('compname',options['compname'])
and then accessed it as
request['compname']
from what i can see, the end script called is a recursive script and
for some reason, it only works if the variable comes from 'request'
and not from 'options'. I am going to make the simplest example of a
recursive script and see if this hypothesis is correct. will revert

hi
i am having a very weird experience. I have a page template
called manageheads. This requires a parameter called
'companyname' to be passed to it. I access this option as:
python:somefunction(companyname=options['companyname'])
when i call the ZPT from the web like so:
http://.../manageheads?companyname=nameofcompany
it works
Are you shure this works? Did you redefine 'options' somewhere?
but if i call it from a python script like so:
return manageheads(companyname=nameofcompany)
it complains saying
key error 'companyname'
It should simply work.
The weird thing is that i have several similar ZPTs where this
call from python scripts work perfectly in the same zope
instance. So why not in this one? any clues?
Maybe you did redefine 'options' in your template.
options has not been redefined anywhere. The problem appears to be in
the way to call a particular python script
this is a bit long, but interesting nevertheless -:)
the variable in question is 'compname' which is either
request['compname'] or options['compname'] depending on how the ZPT
is called (from web it goes to 'request' and from script in goes to
'options')
This is the script:
callheadtree.py
parameter list: compname
theads=context.getheadleafs()
heads=[]
for k in theads:
heads.append(k['id'])
htree=context.getheadtree(compname=compname,id=1,name='chart',ret=[],heads=heads)
headtree=[]
for k in htree:
headtree.append({'name':k})
return headtree
when tested using the test tab it works
when the originating ZPT is called from the web using '?' notation it
works
when called from the following script:
onetest.py
names=callheadtree(compname='testcompany')
return names
it gives a Keyerror 'compname'
when the originating ZPT is called from a script:
it gives a Keyerror 'compname'
Ok, you've got a KeyError, but where? Traceback?
