[Zope] Zope bug or my stupidity?
...I'm betting on the latter :)
The problem in a nutshell is that a dtml method seems to be returning itself
(that is, the dtml source of the method), rather than what it ought to be
returning. I have two classes, a "Topic" class, derived from ObjectMananger, and
a "Story" class. The Topics contain Stories. As you might imagine, I wanted a
method that would dig up the most recent stories in a Topic. So I wrote one and
put it in the the methods of the Topic class. Done with that, I wanted a method
that would decide which of the Stories from each topic to put on the main page.
But a weird thing happened. I got errors telling me that my function was
returing a string (I was trying to use it in a dtml-in tag). That's odd, I
thought, so changed the function to simply spit out the results of the method
call with a dtml-var tag. I discovered that it was spitting out the source of my
dtml method. Yikes! Aren't all variables supposed to be rendered?
Here's the method (named get_storys) in the Topic's methods:
dtml-call "REQUEST.set('stories', [])"
dtml-in "objectValues('Story')" reverse sort=Date
dtml-if numStories
dtml-if "sequence-index (numStories - 1)"
dtml-call "stories.append(id)"
/dtml-if
dtml-else
dtml-if "sequence-index == 0"
dtml-call "stories.append(id)"
/dtml-if
/dtml-if
/dtml-in
dtml-return stories
Here's the method that calls that method:
dtml-in "objectValues('Topic')"
dtml-with sequence-item
dtml-var "get_storys"
/dtml-with
/dtml-in
dtml-with "Economic.ColdFusion"
dtml-var id
/dtml-with
In case you're wondering, I'm running zope 2.2.0.

I am fairly new to zope, but this seems pretty weird, especially the method
returning its dtml source.

And you've been caught by one of the most common (and understandable) newbie
mistakes. (o8.
'sequence-item' is not a valid Python name. To Python it looks like "
sequence - item ", the mathematical expression.
This is a holdover from days of old, and not much has been done to deprecate
it (all my shouting, and that of others, has so far come to naught.)
dtml-var sequence-item will work, because that is in Zope Land... no
quotes.
dtml-var "_['sequence-item']" is the Python Land equivalent. the _[] name
space lookup is your friend for this sort of problem.
dtml-if "sequence-index (numStories - 1)"
should be written as:
dtml-if "_['sequence-index'] (numStories -1)"

Re: [Zope] Zope bug or my stupidity?
Once again I'll point out that I have a patch that allows sequence_item. I've
submitted it to the collector but it was rejected because of the AFAIK
not-yet-scheduled "named dtml-in" feature.
