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

[Zope] Zope bug or my stupidity?

[Peter Hernberg]

...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:














Here's the method that calls that method:









In case you're wondering, I'm running zope 2.2.0.
