Ok I see why deleting using the sync gateway does not work. I've now tried
to delete it directly using the Couchbase Java SDK (wrapped into the ColdFusion
cfcouchbase library <https://www.ortussolutions.com/products/cfcouchbase>).
But for some reason I still seem to doing something wrong - as I get back
documents from the query but as soon as I try to delete them, Couchbase
returns the getStatus().getMessage() as 'Not Found'.
Can you please tell me, where I've done a locigal mistake?
*FYI: the couchbaseClient variable is a ColdFusion wrapper for the Java
Class com.couchbase.client.CouchbaseClient.*
This code is in my added view:
function(doc,meta){
if( !doc._deleted && doc.channels && doc.channels.length && doc.type !=
'Setting' ){
for( var i = 0; i < doc.channels.length; i++ ){
emit(doc.channels[i],doc);
}
}
}
This is saved with the following name (designDocumentName, viewName,
mapFunction):
couchbaseClient.asyncSaveView('channels','channel',... map function code
from above ...)
Then I'm querying this view using the following query (designDocumentName,
viewName, options):
couchbaseClient.query('channels','channel',{ key=arguments.channelId })
Last but not least: I'm looping over the result set and call the delete
function for the document.id:
<cfloop array="#local.docs#" item="local.doc" index="local.index">
<cfset future = couchbaseClient.delete(local.doc.id) />
<cfoutput>#future.getStatus().getMessage()#</cfoutput><cfabort> <!---
this outputs 'Not Found' ---->
</cfloop>
