acts_like?(duck)
Instance Public methods
A duck-type assistant method. For example, Active
Support extends Date to define an
acts_like_date? method, and extends Time to define acts_like_time?. As a
result, we can do x.acts_like?(:time) and
x.acts_like?(:date) to do duck-type-safe comparisons, since
classes that we want to act like Time simply need
to define an acts_like_time? method.
