Overview

Prohibits helper :name calls at controller class scope. Implicit helper inclusion makes the helper method's call site impossible to grep from the controller — call the helper module explicitly where you need it instead.

Examples:

# bad
class FoosController < ApplicationController
  helper :bar
end

# good
class FoosController < ApplicationController
  def show
    @label = BarHelper.label_for(@foo)
  end
end
