View configuration

[Thomas Williams <th...@dubitlimited.com>]

Hi chaps,I've spent a couple of days playing around with version 0.80 and I
think I might be missing something. Is it possible to configure views at
query time or do they have to always be effectively 'static'. I mean can I
write a view something like this:

function(doc, user_id) {
  if(doc.user_id=user_id)
    emit(doc)
}

Then pass user_id as a parameter to each query. If not, does anyone know how
I can go about retrieving data based on a unique key in an efficient manner?

Thanks,
Tom

Views must be pure functions from the doc alone (no other data). The
way to build you query is described at
