Hello all,
I recently upgraded to CouchDB 1.0.2 for development and found some of our view
map functions broke. Apparently it's no longer possible to modify data a doc in
a view function before emitting. I found "Documents are now sealed before being
passed to map functions." in the changelog for 1.0.2.
This is an example of a map function which no longer works under 1.0.2:
----
function(doc) {
if(doc.type === 'schedule') {
var events = doc.events;
if (events) {
events.forEach(function(event) {
var broadcasters = event.broadcasters;
if (broadcasters) {
broadcasters.forEach(function(broadcaster) {
if(broadcaster === 'VPRO') {
event.channel = doc.channel;
event.channelName = doc.channelName;
emit(event.end, event);
}
});
}
});
}
}
}
----
A colleague suggested using this:
----
events.forEach(function(e) {
var event = eval(uneval(e));
----
This creates a deep copy before modifying event properties. It works, but it
looks ugly to me. Is this the way to go or is there a cleaner way?
Nils.
