Subject [jira] [Created] (COUCHDB-1268) "?rev=" URL query parameter
Date Wed, 31 Aug 2011 23:57:09 GMT
"?rev=" URL query parameter
---------------------------

                 Key: COUCHDB-1268
                 URL: https://issues.apache.org/jira/browse/COUCHDB-1268
             Project: CouchDB
          Issue Type: Improvement
          Components: Database Core
    Affects Versions: 1.2
         Environment: linux
            Reporter: gert cuykens
            Priority: Trivial


When PUTting a document you have to specify the current revision as a _rev key in the JSON;
whereas many related requests (like DELETE, COPY and PUT of an attachment) specify the revision
in a "?rev=" URL query parameter instead. The first example, will result into a document conflict
because rev is not specified in the JSON and the rev from the url gets ignored. All other
examples work. I strongly believe JSON bodies like this should never contain _id and _rev
and will improve in much better client code.

curl -X PUT http://localhost:5984/_users/user%3Agert?rev=5xxx -H
'Content-Type: application/json' -d{
 "_id"          : "user:gert",
 "type"         : "user",
 "name"         : "gert",
 "roles"        : [],
 "password_sha" : "",
 "salt"         : ""
}'

curl -X PUT http://localhost:5984/_users/user%3Agert -H 'Content-Type:
application/json' -d{
 "_id"          : "user:gert",
 "_rev":"5xxx",
 "type"         : "user",
 "name"         : "gert",
 "roles"        : [],
 "password_sha" : "",
 "salt"         : ""
}'

curl -X PUT http://localhost:5984/_users/user%3Agert/picture?rev=5xxx
-H 'Content-Type: image/png' -d @picture.png
