I've run up couchdb and am trying to use it to serve JSON requests
from a browser javascript application (using google maps).
I've been doing this with MySQL and RoR but the replication and the
ability to simply add image attachments is very appealing to me.
Essentially the client-side requests points that fall within a given
latitude and longitude boundary i.e. a southwest lat, long and a
northeast lat,long.
These are my first steps with map/reduce but I've determined how I can
use startkey and endkey to pull documents within a latitude. I'm
a bit stumped on a URL query that can do both however.
A simple view such as;
function(doc) {
if (doc.lat && doc.lng) {
emit([doc.lat, doc.lng], [doc._id, doc.rating, doc.name,
doc.description]);
}
}
I'm fortunate in that I'm only having to deal with an area that
doesn't cross the equator or prime meridian so essentially I just need
to query
two floats that fall within ranges provided by startkey and endkey.
I'd be very grateful if someone had some idea as to how to do this..
Cheers!
