Hi all,
This is probably a really simple question, but for some reason* I
can't figure it out.

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]) }
In any case, this isn't valid logic - you need to do something like
theSum = 0;
for (var i in values)
theSum = theSum + values[i][1];
return theSum;
