 looking at it, it seems that the 'correct' way is to call

Yes, here is the idiom I now use everywhere, according to what I read
in the code and documentation:

def addFoo(dispatcher, id, REQUEST=None, **kw):
 Adds a Foo. 
ob = Foo(id)
container = dispatcher.Destination()
container._setObject(id, ob)
if REQUEST is not None:
dispatcher.manage_main(dispatcher, REQUEST)

In any case calling the first argument self is really overloading
the meaning of the word, as we are nowhere near a method here.

[Zope-dev] dynamically using inheritance

2002-02-02 Thread Ed Colmar

Hey all. 

I'm working ona little skinning implementation where I want to pull a 
folder name out of a database, then navigate to it to get dtml methods.

Hardcoding it is easy, but how exactly would I insert a variable into this 
simple dtml-with?

dtml-with skins.default
dtml-var standard_skin_appearance

to get an idea of how the site is layed out, here's where the skins 
and inside data would live:

I tried variations on:

dtml-call REQUEST.set('skinname', 'skins.default')
dtml-with _.string(skinname)

with no luck...  

In the docs, I'm seeingt that it shoulod be possible with the right 
syntax.  What would that be?

Thanks so much!
