In a SkinScript COMPUTE statement, should I be allowed to supply
different names in the OTHERWISE LET section as in the attributes section?
For example:
WITH some_query() COMPUTE
foo,bar,baz
OTHERWISE LET
foo='There is no foo',
spoon='There is no spoon'

DataskinAddons provides a nice DataSkin-derived class for debugging purposes
- it has a debug() method that prints out __dict__, and lets you

The debugger is your friend. ;-). Seriously I'd be lost without it:

Hi Steve,
that did it, many thanks, how did you debug this ? By the way, it only work

didn't work before applying the patch, with an setup like this:

Hi Steve,
somehow I got the first part working, I don´t exactly remember, what was
wrong, but it worked anyhow.
my setup was:
SkinScript method in defaultRack, Data-Skin:
WITH ['a','b'] COMPUTE event_id=RESULT[0],datum_von=RESULT[1]
and under Storage I specified my ZClass and loaded accessin
Hi Joachim,
Hmm... I just put all the code in myself... to be *really* sure, and
it does work. What do you see for 'current attribute handling' in the
Data PlugIns tab of the default rack? I would try to simplify. Take
out all the skin script execpt for the one line.

Hi Steve,
I did exactly (hopefully) as you sugested, but the dtml-method fails with:
(I moved the SkinScript with first to the top)
Error Type: KeyError
Error Value: movie_link

My Experience with 'raw' DataSkins is that you'll quickly
run afoul of the Zope Security system. Using a ZClass that has
ZPatterns:DataSkin as a base class avoids this, and gives
you an easy way to put a 'user interface' on your objects.

Hi Steve,
thanks for the tips, I try to do it without the ZClass, according to my
understanding, and Phil Eby's reply that should work too, but apparently I

Hmm.. I would start start really simple here, and then 'work up'

Yes that's what I found too,
for debugging I inserted in Specialists.py in getItem:
return str(self.rackList) <-- inserted
for rack in self.rackList:
item = rack.__of__(self).getItem(key)
if item is not None: return item
this alway returns an empty list, when calling it from the dtml:
returns "[]"

can I do it just by defining the appropriate SkinScript Method in my

No. I just guessed.
I think I might have read it in the source the other day too.
I'll take a look at the wiki now:

Just out of curiosity, did you find this out by reading the draft

Let's say I have a DataSkin that has a propertysheet "journey", which
has a "steps" property of type "lines". I can expose its "steps"
property as an attribute, and also a neatl
