how to delete if _id="" ?
Hello,
today I got a slightly funny problem. Creating a document using an update
handler, I had the hope an _id would be crated if I dont provide one
(similar to POST do the DB). This hope was in vain, so now I have one
document with _id: "". (I did only once, because the second try gave an
update conflict of course :) Futon doesn't give the possibility to open it
(because a link text of length 0 doesnt make a link in the browsers I
tested: Firefox, Opera, Crome), and I just can't imagine to curl it (curl -X
DELETE http://locahost/sofa/ should rather delete the DB, right??).
Any ideas?
Thank you a lot & kind regards
alux

I had the same issue a few days ago. I did ask about it in the irc channel,
but no one came up with a way to remove it, except for deleting the entire
DB (which worked for me). Apparently, an empty string is considered to be a
legal value for a doc's '_id', even though you can't really do much with
such a document.
I think this edge case is confusing, and maybe should not be exposed to
users at all.
a.

Sounded good.
$ curl -X POST -H "content-type: application/json" http://localhost/sopha -d
@no_id.json
returned
{"ok":true,"id":"9894038c9531e364efee7644dd000c8d","rev":"1-de715bf126efc93d225d9e3f8e8eb81a"}
So it happily created a new document, with a shiny new id. (And then it took
me a while, to understand why I cannot see it in futon. (Futon doesnt show
deleted docs.))
Hm.
Thanks nevertheless. I hadnt tried that.

Hi,
Could you post {"_id": "", "_deleted": true} to the database?
Cheers

I have no idea how you can remove this document, but maybe you could open a JIRA ticket on this (since an empty document ID should not happen).
