问题 I am trying to cover for an issue where CouchDB is rolled back, causing PouchDB to be in the future. I want to find a way to detect this situation and force PouchDB to destroy and reload when this happens. Is there a way to ask PouchDB for it's current pull seq number? I am not able to find any documentation at all on this. My google-foo is not strong enough. So far my only thought is to watch the sync.on(change) feed, and record the seq number on every pull. Then on app reload, run this as

问题 QUESTION Is it possible to query other couchdb documents as part of a standard couchdb validation function ?

问题 I am writing a small Python program that loads some documents into couchdb. It would be very convenient to check whether a database with a certain name already exists, so I can either create a new one or open the existing one. What I want to do is something like this: import couchdb def connect(url, dbName): server = couchdb.Server(url) if dbName exists: # how do I do this? return server[dbName] else: return server.create(dbName) I know a try-except block would do the trick, but isn't there a
