$resource returns Object with numeric attributes

Question

I'm trying to read the return value from a CouchDB _update, which returns a string. I'm calling it via an AngularJS $resource, like so:

var cb = function(rtn){console.log(rtn);};
var foo = $resource('/myDb/_design/myDesignDoc/_update/thingie/:arg', {}, { update: {method: 'PUT'}});
foo.update({arg: "blah"}, null, cb);

This prints the following to the console:

Object { 0: "4", 1: "d", 2: "a", 3: "7", 4: "3", 5: "1", 6: "1", 7: "4", 8: "-", 9: "8", 51 more… }

The attributes with the numeric indexes are my desired output, but how to convert them back into a string?

I've tried rtn.join("") but it complains about not finding rtn.join. I suspect this of being obvious, but I'm stuck for now...

This (unanswered) question appears to be very similar to mine. This one was self-answered, suggesting returning a dictionary rather than a string. Simply returning a dictionary didn't work for me, but returning a JSON string containing a dictionary did, like so:

JSON.stringify({rtn_value: "the actual return value"})

Grumble. This should really be added to the AngularJS docs... maybe I'll do it (or better, someone who reads this should do so!)
