check_class_collision(options={}) protected

Add a class collisions name to be checked on class initialization. You can supply a hash with a :prefix or :suffix to be tested.

check_class_collision :suffix => "Observer"

If the generator is invoked with class name Admin, it will check for the presence of “AdminObserver”.
