Hi,
The output that we get with the _changes database API tells us which
document was changed and its revision information.
Is there a way to get the notification when a particular key of a document
is changed?
Basically is there a way to listen to a specific key of a document of a
database?
For eg: Suppose I have a database as "helloworld", which has 2 documents
"app1" and "app2" whose contents are as follows:
app1 :
{
"_id": "app1",
"_rev": "2-c1765690ce0ba5c4d51bd6e06f6d63e1",
"name": "Hello",
"title": "World"
}
app2:
{
"_id": "1",
"_rev": "2-95ca949e944d55bdb0dc79b8d8223f05",
"a": 2,
"b": 4
}
Now I want to listen to the key "name" of the document "app1" for changes.
So I should receive the notification when the value of "name" changes and
not if the value of "title" changes.
Is there a way to do this in CouchDB? If yes, then how?
Any help would be much appreciated.
Thanks,
Chirayu.
