Expansion

Motivations

We include parent (belongs_to) type relationships in serializations, but should not require n+1 to lookup all parents. This is especially powerful when coupled with the de-nesting strategy.

Example

Addons include a plan. This is usually included in a summary that looks like:

Change Makers - Makers meeting
Geek Out Go Out - Geek social gathering
ICRuby - Ruby developer meeting
Iowa City Open Coffee - Coffee with entrepreneurs and creatives
IowaJS - Javascript developer meeting
Iowa Mobile Developers - iOS, Android, Windows phone meeting
Iowa Tech Chicks - Women's tech meeting
Iowa Web Designers & Developers - Web technology and methodology
OpenHack and Open Source Hardware - Hacker and tinkerer gathering
