You should not build applications on CouchDB's revision system. http://wiki.apache.org/couchdb/Document_revisions says: "You cannot rely on document revisions for any other purpose than concurrency control. Due to compaction, revisions may disappear at any time. You cannot use them for a client revision system."
I suggest looking at other ways to solve your problem, like for instance creating a document per message with a chatroom and a timestamp property and a view to collect all messages by chatroom and timestamp. If you really want to do version control using CouchDB (which I don't believe is what you should be looking at for a chat application) check out this blog post: Simple Document Versioning with CouchDB http://blog.couchbase.com/simple-document-versioning-couchdb Nils. ________________________________________ Van: Jon Morehouse [[email protected]] Verzonden: vrijdag 3 februari 2012 0:30 Aan: [email protected] Onderwerp: Retrieving Multiple Revisions Hello, I'm creating a chat application based on revision history for documents. Each new post is a new revision in my chat room and I am simply querying multiple revisions to update each post. My question is, how do I work with the individual revisions inside of the returned object? Here Is what I'm getting when I print it recursively with PHP, I would like to go in and loop through each json document to make a nicer output: --c89953e79622d85ed9037f797611162f Content-Type: application/json {"_id":"ben","_rev":"1-8159fce5e15466f7ebbffce24824ed6a","message":"this is the first message in this chatroom"} --c89953e79622d85ed9037f797611162f Content-Type: application/json {"_id":"ben","_rev":"2-c6d8d60b58e0d34e9d7bde15c7f57d6d","username":"Ben","message":"BenMessage"} --c89953e79622d85ed9037f797611162f Content-Type: application/json {"_id":"ben","_rev":"3-6e11c76fa6ac5b38d05c210d1d51d941","username":"Ben","message":"BenMessage"} -- Also, for future reference is it good practice to work with revisions like this?
