selective replication not working for deleted source documents
Hi,
I have successfully setup selective replication as I have posted on
http://thinkinginsoftware.blogspot.com/2011/10/couchdb-filtered-replication.html
Everything works perfectly but I have a user story I cannot complete and it is:
When a document is deleted in source
Then the document should be deleted from target
Any idea how can I get this done preferably using the _replicator. I
am not able to discover a magic flag that would allow me to achieve
what I need.
Thanks,
-Nestor

Yes the changes API could be used from a script to do something around
this, in fact filtered replication is based on the change API after
all as it reads the changes feed to decide what to replicate.
I was more interested in an out of the box setting to state something
like "Run filters for all documents" in which case any document
existing in the target but not in the source could be removed of
course as a "one time shot".
Thanks!

I thing if you run a _change request from target/source you should be able
to remove what should be removed. just an idea :)

Great! Tested and worked but only for the new documents I add. Any
documents deleted from source before the addition of the filter will
not be deleted in the destination. Nothing big but definitely to be
kept in mind. Probably there is an option to force even deleting
those?
Thanks!

Your filter function blocks replication of deletions.
add;
if (doc._deleted) {
return true;
}
