[Product-Developers] kupu base href

[Derek Richardson]

I am attempting to rewrite the urls generated by kupu into a different 
format (I'm moving the content between sites and rearranging in the 
process and need links to be uuids, not normal hrefs. I'll transform 
them back into normal hrefs on the other side.). So, I need to take a 
kupu url and traverse to the object it represents.

Kupu generates only relative urls for internal links and depends on the 
base element's href attribute for resolution. So, I need to resolve the 
relative urls into absolute urls, of which I can then chop the front 
part and throw it away, leaving a string I can pass to restricted traverse.

The problem is that I cannot figure out how plone generates the base 
href for a page. For a folder, it seems to be that folder. But, for a 
page, it seems to be the folder the page is in. This surprised me.

This may be as convoluted as it gets, but, having been surprised once, 
I'd like to see the code plone uses to generate the base href. Does 
anyone know where it lives? Or does anyone know a better way to do what 
I'm trying to do?

Thanks,

Derek
