Basic part of sample doesn't work. With clean setup, cannot edit a beer. Solution included.

If you click on [Edit] for any beer, and edit any field and then press [Save Changes], the following error is printed to the browser:

ReferenceError: rc is not defined

Solution

It seems that rc. was erroneously added to the front of rc.doc.brewery_id on line 163 of beer_app.js. Remove the text rc., save the file, and restart the server and the edit feature now works.

  db.get( rc.doc.brewery_id, function(err, result) {

becomes

  db.get( doc.brewery_id, function(err, result) {

Editing should now work.

Note: I'm really surprised this hasn't been noticed for nearly a year now. Is nobody learning to use Couchbase on Node.js?

Note #2: I really wish there were more sample applications for Node.js, more full-fledged examples that show best practices of using Node.js and of using Couchbase. Samples with production-ready error handling, and samples that are perhaps designed to demonstrate the scalability of couchbase as part of the application (like perhaps some data-processing on statistics or something involving alot of data crunching, maybe GeoSpatial). Perhaps someone could suggest some solid open source projects which do this, for me to look over?
