Provides helper functionality for ruby classes that store various database-unfriendly types as instance variables. It automatically serializes and deserializes things like classes and symbols to interact easily with both the database and your application code.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install attribute_helpers
This gem exposes the
attr_class class methods, which when
called will wrap the related instance method to allow for better database
require "attribute_helpers" class Vehicle < ActiveRecord::Base extend AttributeHelpers attr_class :manufacturer attr_symbol :status end car = Vehicle.new car.manufacturer = Tesla # This is a class. car.status = :parked car.save! car = car.reload # After a DB round-trip, typically these fields are strings. car.manufacturer # Tesla (the class) rather than "Tesla" (the string) car.status # :parked (the symbol) rather than "parked" (the string)
Note: while this gem was written to help with ActiveRecord objects, it has no dependencies and works great with any database backend (or none!). You can extend it into pure Ruby classes just fine!
