Hi all,
This is probably a really simple question, but for some reason* I
can't figure it out.
(* reason is most like extreme dumbness on my part)
I've got a bunch of views where i have something like this:
get_all_by_field:
map: if (doc.type == 'my_doc') emit(doc.field, doc);
count_all_by_field:
map: if (doc.type == 'my_doc') emit(doc.field, 1);
reduce: function(keys, values) { return sum(values) }
That works fine, but seems like it could be more elegant ..
I thought I'd be "clever" and try to combine the two, so I could get
the "search" output by calling the map alone, and then getting the
count by turning on reduce, something like this:
map: function(doc) {
if (doc.type == 'my_doc') emit(doc.field, [doc, 1]);
}
reduce: function(keys, values) { return sum(values[1]) }
The idea being that if i turn off reduce, it outputs the docs I want,
but if I turn it on, I can just count the second element in the
emitted array.
But for some reason it doesn't work. I've tried the above, just
returning values[1], trying to sum values[0][1], etc. I either get
errors or nothing.
This is probably some really simple thing that I'm missing in my tired
state. Can anyone give me a hint as to what it is? : )
thanks!
Sho
