--------------------------------------
Summary: In view map function doc object does not have
.constructor defined on any of the contained objects.
Key: COUCHDB-1476
URL: https://issues.apache.org/jira/browse/COUCHDB-1476
Project: CouchDB
Issue Type: Bug
Components: JavaScript View Server
Affects Versions: 1.2
Environment: CouchDB 1.2 Release binary on Windows 2003
Reporter: Andrew Reslan
Priority: Minor
I am doing some complex view map processing using external libraries.
These libraries use the following checks when parsing a JSON document:
function _isObject(v) {
return (v !== null && !_isUndefined(v) && v.constructor === Object);
}
function _isArray(v) {
return (v !== null && !_isUndefined(v) && v.constructor === Array);
}
The 'doc' object passed to the mapping function does not appear to have the
.constructor property defined, nor on any of the enclosed objects, this causes
the JSON processing to fail.
A simple workaround is to stringily the doc object and parse the results back,
the fixed document then has the .constructor properties correctly set on all
objects
var fixed = JSON.parse(JSON.stringify(doc));
