Module: FleetVentures::Serialization

Defined in:
lib/rdf_for_sqlite.rb

Overview

Rather than going through a Rails commit process, I’ve just hijacked this code and run it as my own module. For Spira models, the attributes hash uses symbols rather than strings, and so I have to map them to strings on line 15 below.
