Instance Method Details

#as_json(options = nil) ⇒ Object

Looks for the option ‘:presenter_action`. If it exists, looks for a method called `#as_<presenter_action>_json` and delegates to that method. If `:presenter_action` isn’t in the options, or it references a method that the presenter doesn’t respond to, falls back to the resource’s ‘#as_json` implementation.

e.g.

‘presenter.as_json(presenter_action: :index)`

will delegate to

‘presenter.as_index_json`
