Subject Fwd: Redirect from _list function?
Date Sun, 27 Sep 2009 03:39:58 GMT
Hey guys,

I need to find a way to do a redirect from a _list function after
calling the getRow() function. After looking at render.js for a while
I can't see how to solve this without at least adding to the API.

Basically, I think that calling getRow() shouldn't cause the view
server to send the headers (or awaiting chunks) unless we've already
called send() or something like that. That way, we can return from the
_list function after iterating to the first row that should redirect.
(I'm not sure if this is a breaking change from the current semantics,
however...)

Would greatly appreciate a little guidance on how to attack this!


Cheers,

Zach

Yes... The headers are sent when the first getRow is called. Fixing
this is definitely something I'd support.
