new ActiveSupport.Initializer(options)

• options (Object)

The options hash can contain:

• database (String | Array): URL of a JSON database to load, or an array of arguments to ActiveRecord.connect
• routes (Object | Function): A hash of routes, or a function that returns one. Usually a function is needed as the objects that will be routed to are not available when the initializer is loaded.
• callback (Function): The function to be called when the initializer has completed.
