Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object

Used to proxy all method and attribute requests not implemented on the controller to the model.

On first call of a missing method a method is generated to avoid the missing lookup next time, this should be faster for repeated lookups of the same method, e.g. reg

Instance Method Details

#controller ⇒ Object

Means that when dealing with a controller/model pair, you can always call obj.model and obj.controller to get the one you want, regardless of the one you currently have.
