Hi,
=20
This has been buggering me for ages, and I've spent too many hours
trying to figure it out already, so I'm resorting to the list for help.
:)
=20
I have two functions, PlainFunc and DTMLFunc, where PlainFunc is Python
method in a file system product, and DTMLFunc is a DTML Method in the
ZODB.
=20
What I want to do is this:
=20
ZPublisher calls PlainFunc (publishes it)
PlainFunc calls DTMLFunc
=20
in such a way that DTMLFunc gets everything it needs, e.g., namespace,
but PlainFunc can do funky things to this namespace before-hand (like
insert a few variables into it). In other words, I want a Python method
to wrap around a DTML method.
=20
I've encountered many problems caused by the awkward calling conventions
for DTML methods and the automagic switching between different calling
conventions by the ZPublisher (isDocTemp; can I set that for a normal
Python method?). Right now, I'm struggeling because I cannot get the
namespace to be passed to PlainFunc, therefore PlainFunc cannot pass the
namespace on to DTMLFunc. Any clues?
=20
Bye,
--=20
