Your situation is perfectly covered by REST approach.

According to that approach you should have the single IncidentsController controller. Then you should have

  1. show action which would expose particular incident to show.html.erb view as @incident instance variable
  2. index action which would expose the list of all (or some) incidents to index.html.erb view as @incidents instance variable.

So you don't need and should not call some controller's action from another controller's action.

It's the "Rails Way", it's the "REST Way". It's the way how one should do that.

The simplest tip in your situation is generate rails scaffold for your incidents resources and use the generated files properly to set up things.

rails generate scaffold Incident
