#all ⇒ Object

This is a basic implementation that just delegates to find_all.

def all
  find_all
end

#find(criteria = :all, *args, &evaluator) ⇒ Object

Simple pattern for delegating find operations to the resource. This is pretty similar to earlier AR versions that did not proxy to Relation.

The biggest difference is that all finder methods accept an evaluator block allowing bulk operations to be performed on returned results.
