What’s the proper way to initialize a class_attribute in Rails?
I am using this:
class Foo < ActiveRecord::Base
class_attribute :foobar
self.foobar = []
# ...
end
Which seems to work fine, but also seems to look a bit non-Railsy to me.
Everything is described here: http://apidock.com/rails/Class/class_attribute
If you click on “Show source” you will see there are no options available to set default value. You are doing it right.
