Where can I find good AREL documentation? [closed]

Answer 1

I wrote an article about Arel a few weeks ago (The definitive guide to Arel, the SQL manager for Ruby). It walks through the whole library and explains how things work internally and how you can use it from your own application.

Answer 2

I got tired of reading tests and code, in the arel tree, so I put some slides together. They cover v2.x, I haven't even looked at v3 yet.

Answer 3

Complete documentation is here: http://rubydoc.info/github/rails/arel/master/Arel Look in the modules for specific methods.

Answer 4

Yeah, I'm having a real hard time finding doc too. The Arel test suite might be of some use:

Answer 5

I think that this will be useful :
