Getting error while deleting a document in couchdb using node-couchdb-api

Question

Getting error while deleting a document in couchdb using node-couchdb-api

var couchdb = require("couchdb-api");
var server = couchdb.srv(localhost, 5984, false, false);
var db = server.db("test");
var doc = db.doc("d5e1d042d579fcb1b3d4df07bc001f74");
doc.del(function (err, response) {
console.log(response);
console.log(err);
});

after that i am facing the problem,

null
{ error: 'bad_request', reason: 'Invalid rev format' }

but the corresponding document having the proper revision like 1-135dc47e3492a980fa45b3af9eb22a97 and proper data.

Please provide me the solution.

Thanks in advance.

I'm the creator of this module. The issue here is that you are attempting to delete the document without a revision number. (there is a _rev number on your document, but couchdb-api does not have that information) Any other attempt to write would also trigger this error under these conditions.

You have a couple options as it stands now:

Get the current document before attempting to write/delete

doc.get(function (err, body) {
    doc.del(function (err, results) {
        // the delete will be successful
    });
});

Explicitly set your revision number before attempting the write/delete

doc.body._rev = "1-myrevisionnumber";
doc.del(...);

I'm going to add a better error message here, and I'm considering adding a special flag that will tell couchdb-api to "force" a delete even if it doesn't have the latest revision number. (ie. it will call get before del in order to avoid MVCC)
