Hi there,
I'd like to model the following relationships in my database:
project has_many documents
document has_many versions
I've written a view which will return all documents plus a version count:
map:
----
function(doc) {
if(doc.type == "document") {
emit(doc._id, doc)
}
if(doc.type == "version") {
emit(doc.document_id, 1)
}
}
reduce:
-------
function(keys,values) {
var count = 0;
var doc;
for(var i = 0 ; i < values.length ; i++) {
value = values[i];
if(typeof(value)=="number") {
count+=i;
} else {
doc = value;
}
}
doc.version_counter = count;
return doc;
}
The request my_database/_view/document/with_version_count?group=true
returns the results I need. However, I'd like to restrict these
results to a specific project. Is that possible? Only documents have a
project_id attribute, versions don't know which project they belong
to. I could always just add a project_id to each version, but I
thought there might be a better way. Any help would be much
appreciated.
Cheers
Adam
