The session starts with a quick overview of the technique used to create a class that acts like an Active Record Model class, while not inheriting from ActiveRecord::Base.

This is followed by a code review of the results of applying the technique. Particular attention is paid to handling query conditions, and rewriting/remapping sql table references.

The session wraps up with lesions learned in the exercise.

A secondary benefit of the session for newer developers is to demonstrate techniques and willingness to deal with Rails source and internals.

I have 32 years industry experience; 8 of it in Smalltalk, and 25 in Objects of various kinds. I have worked on most aspects of the tool chain from compilers to SCM systems, and high end engineering modeling tools to financial modeling tools. I am on my third startup, and glad to be back into the Smalltalk/Ruby family of languages.
