How to create a new Database per new user in CouchDB without application Tier

Question

I'm facing the "How to keep private user data private in CouchDB" challenge. Detailed quite well on the couchdb wiki: http://wiki.apache.org/couchdb/PerDocumentAuthorization

I've chosen to make a new database per user, because that's the best fit for the applications I'm creating and because there's a lot of advice from the community to go that route.

I'm having trouble figuring out how to do this. Is there a built in way to do this in CouchDB? So far I have no other need for a middle tier or application tier, and would love to keep this purely a couch + htmll5 application. What is the best case practise for this?

Answer 1

A new feature will add support for auto creating/deleting a database per user.

The following section will be added to default.ini and local.ini:

[couch_peruser]
; If enabled, couch_peruser ensures that a private per-user database
; exists for each document in _users. These databases are writable only
; by the corresponding user. Databases are in the following form:
; userdb-{hex encoded username}
enable = true

; If set to true and a user is deleted, the respective database gets
; deleted as well.
delete_dbs = true
