How to check availability and reserve usernames in CouchDB

Question

Hi

I have a registration page which asks the user to enter a username and email address.

I need to check to see if the username + email is available. How to do I do this with just one http request.

BTW: the username is used as the docID.

What I'm doing right now is check to see if the docID exists, then using a view to check for the availability of the email address. But that's 2 http requests.

I thought about using a view to emit [ username, email ] as the key and query the view with a "key" param = [ username, email ]. But this won't work if the username and email belong to different existing users.

Thanks

Thanks for tip for using email address to login.
