What's wrong with Ruby libraries for CouchDB?

During the last year, I have worked on couple of Ruby/Rails based projects where the primary datastore was CouchDB. CouchDB, to me, is a dream database for web developer come true. The simplicity, the HTTP-based API, the abandonment of SQL semantics, the inspiring community, that all reminds me of when I came into Rails years ago.

However, working with Couch in Ruby and Rails is very, very painful, in my opinion. I'd like to briefly summarize some of my frustrations here. Maybe they are shared, maybe not -- if they are, I think we should launch some coordinate effort to make using Couch in Ruby a pleasure and intelectual satisfaction, not endless loops of research and hacks to „make it work“.

Please note, that my interest is solely to stir the debate. I may be severely mistaken in any point. But, I'd like using Couch in a Ruby application to be a joy, not a frustration, which is what I've met more times than I'd ha

What Killed Waterfall could Kill Agile.

Robert C. Martin
20 Nov, 2010

In 1970 a software engineer named Dr. Winston W. Royce wrote a seminal paper entitled Managing the Development of Large Software Systems. This paper described the software process that Royce felt was appropriate for large-scale systems. As a designer for the Aerospace industry, he was uniquely qualified.

He began the paper by setting up a straw-man process to knock down. He described this naïve process as “grandiose”. He depicted it with a simple diagram on an early page of his paper. Then the paper methodically tears this “grandiose” process apart. In the end, Royce proposed a far more nuanced and insightful approach, leaving the reader to giggle at the silliness of the “grandiose” model.

le API design

A consumer needs to lookup a single user by their github name (jordanbyron). That consumer doesn't know the user's ID. There is a possibility to also search by email and twitter.

"/users.json?github=jordanbyron"
=> [{github: "jordanbyron", id: 1}]

When there are no results an empty array is returned

"/users.json?github=noexist"
