to_map

A to_map function is very useful when you want to convert models to PLAIN OLD DATA. Think presenters, conductors, APIs, JSON, etc...

Installation

Add this monkey-patch to your Rails project and call it on your model instances.

Example Models

What the what?!

Ruby objects can be built in a way such that they are easier to use/test/debug from the point of view that if you do not automatically run their intended functionality from the constructor, potential side-effects and bugs can be better examined.

In general, I find it helpful to consider a constructors' purpose constrained only to setting instance-level attributes based on the passed arguments or using pre-defined defaults. Anything outside of that, I would consider setting up a class-level factory method.

Consider creating semantically-named factory style class methods that create an object and then call a specific method.

I find this especially helpful for hand-rolled presenters and worker classes (e.g. for Resque).
