Hi there, I am new to couchdb and currently stuck with the sample app I am working on.
I managed to put some data into couchdb, for example: File CountLineCode SumCyclomatic RatioCommentToCode content/events/src/nsQueryContentEventHandler.cpp 432 226 0.12 content/events/src/nsXMLEventsElement.cpp 47 11 0.79 content/events/src/nsXMLEventsManager.cpp 352 94 0.15 content/html/content/src/nsClientRect.cpp 82 35 0.48 content/html/content/src/nsFormSubmission.cpp 813 187 0.49 content/html/content/src/nsGenericHTMLElement.cpp 2652 646 0.13 content/html/content/src/nsHTMLAnchorElement.cpp 456 132 0.18 content/html/content/src/nsHTMLAreaElement.cpp 365 101 0.16 content/html/content/src/nsHTMLAudioElement.cpp 43 26 1.02 (every row is put into its own document) Now I want to query the datastore using map/reduce views. The reduce function should add the values for a given key (keys are part of the file value). For example a query for "content/html/content/src/nsFormSubmission.cpp" would result into "CountLineCode": 813, "SumCyclomatic": 187, "RatioCommentToCode": 0.4. A query for "content/html/" would add the values where File matches the given prefix. "content/" would add more and "" would add the values of all documents. I feel that this is exactly what couchdb is good at and I think there is a very simple solution to this. Unfortunately I do not have much practise with the map reduce functions and I need some help. Maybe there is tutorial available to help with similar path oriented views? Maybe I got it all wrong and should put all the lines above into one single document. I had this before but futon stopped working nicely because the document had about 5000 lines. I think in this scenario I could not even apply the map reduce functions. I have to traverse the document by myself. What do you think? regards, Mark
