Class Method Details

.decorate(base) ⇒ Class

Why ‘.decorate`? In my tests for Rails 5.2, I’m not able to use the prepended nor included blocks to assign a class_attribute when I “prepend” a module to the base class. This method allows me to handle that behavior.

Parameters:

  • base (Class)

Returns:

  • (Class) —

    the given base, now decorated in all of it’s glory
