Howdy. I'll get right to it:
Say I have a folder structure, a/b/c
I'm in c. I want to establish some kind of method (my current attempts are a python script), stored in a, which will render the following:
<a href="http://myserver.org/a/">A</a>: <a href="http://myserver.org/a/b/">B</a>: <b>C</b>:
My current attempt only gets me:
<a href="http://myserver.org/a/">A</a>: <b>C</b>:
Here's the code for recursiveLinks:
--- SNIP ---
import string
if list == None: list = []
if len(list) > 0: list.append( '<a href="%s">%s</a>' % ( context.absolute_url(), context.title or context.id ) ) else: list.append( '<b>%s</b>' % context.title or context.id )
if context is container: list.reverse() print string.join(list,' > ') return printed else: # this doesn't work: return context['..'].recursiveLinks(list=list) return container.recursiveLinks(list=list)
--- SNIP ---
Now, what I _really_ want is for 'context' to give me an object which is 'the context one level up from here', so I can recursively step up until i hit a folder I somehow designate as "top". I thought I was getting that with context and container, but as it turns out, container, where the above python script (recursiveLinks) lives, is not the container of context (the 'c' folder in this case) -- it's the container of the script (near as I can tell, since the result I'm getting is A: C and not A: B: C)
How can I get 'next-folder-up' from this, in an object context so that I can grab the 'title' and other attributes off of the object, and recurse (as I thought I was doing above) by going to yet another 'next-folder-up'?
Any help here's appreciated. I'm about 48 hours into learning zope. :)
