[Zope-dev] Python method wrapping around DTML method

2003-01-03 Thread Bjorn Stabell 
Title: Message



Hi,

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. :)

I have 
two functions, PlainFunc and DTMLFunc, where PlainFunc is Python method in a 
file system product, and DTMLFunc is a DTML Methodin the 
ZODB.

What I 
want to do is this:

 ZPublisher calls PlainFunc (publishes 
it)
 PlainFunc calls DTMLFunc

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.

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?

There isnt one true namespace. You can create your own as easy as { }, and it 
will be as good as any other.

If you want an authentic ZPublisher namespace then you need

It is pretty simple:

class myProduct:

# The dtml object
DtmlFunc = HTMLFile('DtmlFunc', globals())

# to call it
def PlainFunc(self):
Remember docstring
extraParameter = 'Some string'
return self.DtmlFunc(self, self.REQUEST,
extraParameter=extraParameter)
