def define_json_presenter_class(klass)
  @json_presenter_class = klass
end

#json_presenter_class ⇒ Object

Returns the presenter class if it has been explicitly set or can be implied through naming conventions, or returns nil if no presenter class exists.

By default, the presenter class is inferred to be named after the model class, but with the suffix of “Presenter”.

e.g. If you have a model class called Foo, its presenter is assumed to be called FooPresenter

Alternatively, the presenter class can be explicitly defined with ::defined_json_presenter_class
